Yhteiskuntavastuuraportointi kansainvälisissä öljy-yhtiöissä vuonna 2013

Tutkimuksen tavoitteena oli selvittää, kuinka suuret yhdysvaltalaiset ja eurooppalaiset öljy-yhtiöt raportoivat yhteiskuntavastuustaan vuonna 2013 sekä kuinka laadukasta ja laaja-alaista raportointi oli. Yhtiöiden raportointia tutkittiin GRI-viitekehyksen taloudellisen, sosiaalisen ja ympäristövastuun näkökulmasta. Yritysten raportointia arvioitiin myös maa-alue- sekä liikevaihtokohtaisesti tutkien, voidaanko eroja näiden suhteen löytää. Lisäksi raportoinnin laatua analysoitiin yritysten asettamien yhteiskuntavastuutavoitteiden määrän kautta. Tutkimuksessa selvitettiin myös GRI-viitekehyksen sekä muiden yleisimpien yhteiskuntavastuuviitekehyksien käyttöä tutkimusyrityksissä. Tutkimusaineisto koostui 30:stä listatusta yhdysvaltalais- ja eurooppalaisyrityksen vuoden 2013 yhteiskuntavastuuraporteista. Tutkimustapana käytettiin kvalitatiivista sisällönanalyysiä. GRI-viitekehys oli tutkimusyrityksissä käytetyin viitekehys. Tulosten mukaan eurooppalaisyritykset raportoivat pääsääntöisesti laadukkaasti vastuustaan ja raportointi oli Euroopassa selkeästi Yhdysvaltoja laadukkaampaa kaikilla vastuun osa-alueilla. Tutkimusyrityksen koko vaikutti raportoinnin laajuuteen sekä määrään vain Yhdysvalloissa. Suuremmat yhdysvaltalaisyritykset raportoivat pienempiä paremmin. Tulosten perusteella yrityksen koko ei vaikuttanut tavoitteiden määrään. Maantieteellinen sijainti vaikutti raportoinnin laatuun. Eurooppalaisyritykset raportoivat laajemmin, laadukkaammin sekä asettivat tavoitteita huomattavasti yhdysvaltalaisia yrityksiä useammin ja enemmän kaikilla vastuun osa-alueilla.

Pääomasijoittaminen metsäteollisuuteen vuosina 1995-2005

Tutkimuksen tavoitteena oli selvittää metsäteollisuuteen tehtyjä pääomasijoituksia. Tutkimuskohteena olivat kansainväliset metsäteollisuusyritykset ja niihin tehdyt pääomasijoitukset vuosina 1995-2005. Tutkimuksessa tarkasteltiin miten pääomasijoitukset metsäteollisuuteen ovat kehittyneet lukumääräisesti sekä miten metsäteollisuuteen tehtävien pääomasijoitustenkoko on muuttunut tällä ajanjaksolla. Tutkimuksessa tarkasteltiin myös metsäteollisuuteen sijoittavien pääomasijoittajien maantieteellistä jakautumista sekä näiden kohdeyhtiöiden maantieteellistä jakautumista. Tutkimustulosten mukaan pääomasijoittaminen kansainvälisiin metsäteollisuusyrityksiin on lisääntynyt vuosina 1995-2005. Pääomasijoitukset metsäteollisuuteen ovat pysyneet keskimääräiseltä kooltaan samalla tasolla koko tarkasteluajanjakson. Metsäteollisuuden pääomasijoituksista lähes puolet tuli eurooppalaisilta pääomasijoittajilta tarkasteluajanjaksona. Viime vuosina pohjoisamerikkalaiset, eurooppalaiset ja aasialaiset pääomasijoittajat ovat jokainen tarjonneet metsäteollisuuden vuosittaisistapääomasijoituksista lähes yhtä suuren osuuden. Metsäteollisuuteen sijoittavatpääomasijoittajat preferoivat sijoituksissaan omaa maantieteellistä aluettaan.

Sähkönjakeluverkon komponenttien pitoajat

Suomessa sähkönjakeluverkkoyhtiöt toimivat verkkovastuualueillaan yksinoikeudella. Verkkovastuualuiden ominaispiirteet voivat olla hyvin erilaiset. Energiamarkkinavirasto valvoo sähkömarkkinalainsäädännön noudattamista jakeluverkkotoiminnassa. Jakeluverkonhaltijat on velvoitettu Energiamarkkinaviraston valvontamallin kautta määrittämään tiettyjen rajoitusten mukaisesti verkkokomponenteillensa sopivimmat teknistaloudelliset pitoajat. Nämä pitoajat vaikuttavat varsinkin verkkoyhtiön tuottomahdollisuuksiin ja asiakkaiden siirtohintoihin. Lisäksi huomioon on otettava jaettavan sähkön laatu, verkon käyttövarmuus sekä vaikutukset ympäristöön ja turvallisuuteen. Pitoaikojen matemaattinen mallintaminen on usein monimutkaista. Teknistaloudellinen pitoaika valitaankin monesti kokemuksen ja harkinnan perusteella. Tärkeimmät reunaehdot jakeluverkkokomponenttien teknistaloudellisten pitoaikojen valinnalle muodostavat verkkovastuualueen sähkönkulutuksen kasvun sekä infrastruktuurin muutoksen nopeudet. Hitaan muutoksen alueilla verkkokomponenttien teknistaloudelliset pitoajat lähenevät teknisiä pitoaikoja, joihin vaikuttavat voimakkaasti verkkovastuualueen maantieteelliset ja ilmastolliset ominaispiirteet. Yhtiöittäin vaihtelevat verkon rakennus- ja ylläpitomenetelmät tulee myös huomioida. Tässä diplomityössä keskitytään pääosin sähkönjakeluverkon komponenttien teknistaloudelliseen pitoaikaan verkon ja verkkovastuualueen ominaispiirteiden kautta. Aluksi määritellään jakeluverkon pitoaika usealla eri tavalla, sekä selvitetään pitoajan merkitystä nykytilanteessa. Lisäksi työn alkuosassa esitellään Energiamarkkinaviraston vuoden 2005 alusta käyttöönotettu jakeluverkkotoiminnan hinnoittelun kohtuullisuuden valvontamalli ja käydään läpi teknistaloudellisen pitoajan merkitys siinä. Sen jälkeen tarkastellaan jakeluverkkokomponenttien ja niiden osien tekniseen pitoaikaan vaikuttavia tekijöitä. Erityisesti puupylväisiin ja niihin liittyviin ajankohtaisiin asioihin kiinnitetään huomiota, koska puupylväät määräävät monesti koko ilmajohtorakenteen uusimisajankohdan. Lisäksi suolakyllästeiselle puupylväälle esitetään yleinen rappeutumismalli ja jakelumuuntajan rappeutumistapahtumaa tutkitaan. Lopuksi tarkastellaan Graninge Kainuu Oy:tä jakeluverkonhaltijana sekä määritetään sen verkkovastuualueelle ominaisia komponenttien teknisiä ja teknistaloudellisia pitoaikoja haastattelujen, tuoreimpien lähteiden, tutkimustulosten, vertailun ja harkinnan avulla.

Diplomityö on tehty Stora Enso -konserniin kuuluvalle Stora Enso Timberille. Tutkimuksen ensisijaisena tavoitteena on ollut analysoida Honkalanden sahan röntgenin mittaamia laatutietoja. Tavoitteena oli selvittää, voiko laatutietojen perusteella määrittää leimikkokohtaisia laatueroja eri maantieteellisille alueille tai kasvupaikkatyypeille.

St. Petersburg Court Chant and the Tradition of Eastern Slavic Church Singing

The present study examines the repertory of liturgical chant known as St. Petersburg Court Chant which emerged within the Imperial Court of St. Petersburg, Russia, and appeared in print in a number of revisions during the course of the 19th century, eventually to spread throughout the Russian Empire and even abroad. The study seeks answers to questions on the essence and composition of Court Chant, its history and liturgical background, and most importantly, its musical relationship to other repertories of Eastern Slavic chant. The research questions emerge from previous literary accounts of Court Chant (summarized in the Introduction), which have tended to be inaccurate and generally not based on critical research. The study is divided into eight main chapters. Chapter 1 provides a survey of the history of Eastern Slavic chant and the Imperial Court Chapel of St. Petersburg until 1917, with special emphasis on the history of singing traditional chant in polyphony, the status of the Court Chapel as a government authority, and its endeavours in publishing church music. Chapter 2 deals with the liturgical background of Eastern chant, the chant genres, and main repertories of Eastern Slavic chant. Chapter 3 concentrates on chant sources: it introduces the musical notations utilised, after which a typology of chant books is presented. The discussion continues with a survey of the sources of Court Chant and their content, the specimens selected for closer analysis, the comparative materials from other repertories, and ends with a commentary on some chant sources that have been excluded. The comparative sources include a specimen from around the beginning of the 12th century, a few manuscripts from the 17th century, and printed and manuscript chant books from the early 18th to early 20th century, covering the geographical area that delimits to the western Ukraine, Astrakhan, Nizhny Novgorod, and the Solovetsky Monastery. Chapter 4 presents the approach and methods used in the subsequent analytical comparisons. After a survey of the pitch organization of Eastern Slavic chant, the customary harmonization strategy of traditional chant polyphony is examined, according to which a method for meaningful analysis of the harmony is proposed. The method is based on the observation that the harmonic framework of chant polyphony derives from the standard pitch collection of monodic chant known as the Church Gamut, specific pitches of which form eight harmonic regions that behave like the usual tonalities of major and harmonic minor. Because of the considerable quantity of comparative chant forms, computer-assisted statistical methods are applied to the analysis of chant melodies. The primary chant forms and their respective comparative forms have been pre-processed into reduced chant prototypes and divided into redactions. The analyses are carried out by measuring the formal dissimilarities of the primary chant forms of the Court Chant repertory against each comparative form, and also by measuring the reciprocal dissimilarities of all chant versions in a redaction, the results of which are subjected to agglomerative hierarchical clustering in order to find out how the chant forms relate to each other. The dissimilarities are determined by applying a metric dissimilarity function that is based on the Levenshtein Distance. Chapter 5 provides the melodic and harmonic analyses of generic chants (chants used for multiple texts of different lengths), i.e., chants for stichera samoglasny and troparia, Chapter 6 of pseudo-generic chants (chants that are used for multiple texts but with certain restrictions), i.e., chants for heirmoi, prokeimena, and three other hymns, and Chapter 7 of non-generic chants, covering nine chants that in the Court repertory are not shared by multiple texts. The results are summarized and evaluated in Chapter 8. Accordingly, it can be established that, contrary to previous conceptions, melodically, Court Chant is in effect a full part of the wider Eastern Slavic chant tradition. Even if it is somewhat detached from the chant versions of the Synodal square-note chant books and the local tradition of Moscow, it is particularly close to chant forms of East Ukraine and some vernacular repertories from Russia. Respectively, the harmonization strategies of Court Chant do not show significant individuality in comparison with those of the available polyphonic comparative sources, the main difference being the part-writing, which generally conforms to western common practice standard, whereas the deviations from this tend to be more significant in other analysed repertories of polyphonic chant. Thus, insofar as the subsequent prevalence of Court Chant is not based on its forceful dissemination by authorities (as suggested in previous literature but for which little tangible evidence could be found in Chapter 1), in the present author’s interpretation, Court Chant attained its dominance principally because musically it was considered sufficiently traditional, and as a chant body supported by the government, was conveniently available in print in serviceable harmonizations.

Surface transformation hardening of carbon steel with high power fiber laser

This study investigated the surface hardening of steels via experimental tests using a multi-kilowatt fiber laser as the laser source. The influence of laser power and laser power density on the hardening effect was investigated. The microhardness analysis of various laser hardened steels was done. A thermodynamic model was developed to evaluate the thermal process of the surface treatment of a wide thin steel plate with a Gaussian laser beam. The effect of laser linear oscillation hardening (LLOS) of steel was examined. An as-rolled ferritic-pearlitic steel and a tempered martensitic steel with 0.37 wt% C content were hardened under various laser power levels and laser power densities. The optimum power density that produced the maximum hardness was found to be dependent on the laser power. The effect of laser power density on the produced hardness was revealed. The surface hardness, hardened depth and required laser power density were compared between the samples. Fiber laser was briefly compared with high power diode laser in hardening medium-carbon steel. Microhardness (HV0.01) test was done on seven different laser hardened steels, including rolled steel, quenched and tempered steel, soft annealed alloyed steel and conventionally through-hardened steel consisting of different carbon and alloy contents. The surface hardness and hardened depth were compared among the samples. The effect of grain size on surface hardness of ferritic-pearlitic steel and pearlitic-cementite steel was evaluated. In-grain indentation was done to measure the hardness of pearlitic and cementite structures. The macrohardness of the base material was found to be related to the microhardness of the softer phase structure. The measured microhardness values were compared with the conventional macrohardness (HV5) results. A thermodynamic model was developed to calculate the temperature cycle, Ac1 and Ac3 boundaries, homogenization time and cooling rate. The equations were numerically solved with an error of less than 10-8. The temperature distributions for various thicknesses were compared under different laser traverse speed. The lag of the was verified by experiments done on six different steels. The calculated thermal cycle and hardened depth were compared with measured data. Correction coefficients were applied to the model for AISI 4340 steel. AISI 4340 steel was hardened by laser linear oscillation hardening (LLOS). Equations were derived to calculate the overlapped width of adjacent tracks and the number of overlapped scans in the center of the scanned track. The effect of oscillation frequency on the hardened depth was investigated by microscopic evaluation and hardness measurement. The homogeneity of hardness and hardened depth with different processing parameters were investigated. The hardness profiles were compared with the results obtained with conventional single-track hardening. LLOS was proved to be well suitable for surface hardening in a relatively large rectangular area with considerable depth of hardening. Compared with conventional single-track scanning, LLOS produced notably smaller hardened depths while at 40 and 100 Hz LLOS resulted in higher hardness within a depth of about 0.6 mm.

Sorbent characterization for circulating fluidized bed scrubbers

Harmful sulfur dioxide (SO2) emissions from power plants have increasingly been restricted since the 1970’s. Circulating fluidized bed (CFB) scrubber is a dry flue gas desulfurization method of absorbing SO2 out of the flue gas with sorbent. In current commercial plants, the used sorbent is commercial or on-site hydrated calcium hydroxide. The CFB scrubber process is characterized by a close but adequate approach to the flue gas saturation temperature that is achieved by spraying water to the absorber followed by a particulate control device. Very high SO2 removal is achieved along with a dry byproduct that is continuously recirculated back to the absorber for enhanced sorbent utilization. The aim of this work is to develop a method that would characterize the reactivity of sorbents used in CFB scrubbers and to conclude how different process parameters and sorbent properties affect the sulfur absorption. The developed characterization method is based on a fixed bed of sorbent and inert silica sand, through which an SO2 containing gas mixture is led. The reaction occurs in the bed and the SO2 concentration in the outlet as a function of time, a breakthrough curve, is obtained from the analyzer. Reactivity of the sorbents are evaluated by the absorbed sulfur amount. Results suggest that out of process parameters, lower SO2 concentration, lower temperature and higher moisture content enhance the desulfurization. Between different sorbents, specific surface area seems to be the most significant parameter. Large surface area linearly leads to more efficient desulfurization. Overall, the solid conversion levels in the tests were very low creating uncertainty to the validity of the results. New desing is being planned to overcome the problems of the device.

Research progress in wood-plastic composites: A review

The interest towards wood-plastic composites (WPCs) is growing due to growing interest in materials with novel properties, which can replace more traditional materials, such as wood and plastic. The use of recycled materials in manufacture is also a bonus. However, the application ofWPCs has been limited because of their often poor mechanical and barrier properties, which can be improved by incorporation of the reinforcing fillers. Nanosized fillers, having a large surface area, can significantly increase interfacial interactions in the composite on molecular level, leading to materials with new properties. The review summarizes the development trends in the use on nanofillers for WPC design, which were reported in accessible literature during the last decade. The effect of the nanofillers on the mechanical properties, thermal stability, flammability and wettability ofWPC is discussed.

Home Made Cars: An insight on Consumer Ethnocentrism – Case Saab

Saab outstands in the history of the Finnish car manufacturing. This is not only due to that these cars have been manufactured in Finland more than other passenger vehicles altogether. Finns also have a special emotional attachment to the “Finnish Saabs”. Findings from previous studies show that consumers connect cars well to the origin of the brand (COB). They are however rarely aware of the Country of Manufacturing (COM). Domestic brands are often popular in the COB, but research from situations in which the domestic origin is limited to the COM is rare. The case of this study is a phenomenon, in which the products origin is two dimensional and divided into domestic COM and foreign COB. The aim is to understand the phenomenon’s effect on consumer behavior. The research problem is approached with two sub questions: • Which country do consumers perceive as the origin country of the car? • What is the role of this origin in the consumers’ product perception and purchasing decision of the car? The theoretical framework of this study applies previous findings of two areas of interest: Country of Origin effect and Consumer Ethnocentrism. This is followed by feasibility studies that present and discuss the history and current state of Finnish car manufacturing. Based on the findings of earlier stages of the study, the role of the domestic COM on consumer behavior is presumed high. This expectation is confirmed by the experts and also by the first consumer respondent, who states domestic origin having been the main motivation to his car choice. All further consumer respondents do however not connect Saab to the home country, but discuss it as a Nordic car. This unexpected finding means that they do not perceive the origin to be neither the COM nor COB, but a geographical area that includes both countries. In other words, consumers have widened their in-group in a way that is in this thesis explained with reference group theory. The consumers’ perceived origin of the car is in this research found to be an important factor to the consumers’ product perception and purchasing decision. Being fit for the yields of the local environment is discovered to have been the most important factor to Finnish consumers purchasing choice of a Saab and the Nordic origin has been an indicator of this fit to them.

Design and characterization of large area position sensitive radiation detectors

Planar, large area, position sensitive silicon detectors are widely utilized in high energy physics research and in medical, computed tomography (CT). This thesis describes author's research work relating to development of such detector components. The key motivation and objective for the research work has been the development of novel, position sensitive detectors improving the performance of the instruments they are intended for. Silicon strip detectors are the key components of barrel-shaped tracking instruments which are typically the innermost structures of high energy physics experimental stations. Particle colliders such as the former LEP collider or present LHC produce particle collisions and the silicon strip detector based trackers locate the trajectories of particles emanating from such collisions. Medical CT has become a regular part of everyday medical care in all developed countries. CT scanning enables x-ray imaging of all parts of the human body with an outstanding structural resolution and contrast. Brain, chest and abdomen slice images with a resolution of 0.5 mm are possible and latest CT machines are able to image whole human heart between heart beats. The two application areas are presented shortly and the radiation detection properties of planar silicon detectors are discussed. Fabrication methods and preamplifier electronics of the planar detectors are presented. Designs of the developed, large area silicon detectors are presented and measurement results of the key operating parameters are discussed. Static and dynamic performance of the developed silicon strip detectors are shown to be very satisfactory for experimental physics applications. Results relating to the developed, novel CT detector chips are found to be very promising for further development and all key performance goals are met.

Jatkotoimenpiteiksi ehdotetaan laitteiston jatkotestausta, liikkeen ja nopeuden testausta sekä lopulta paikkaherkkyystoiminnon toteuttamisperiaatteen valintaa ja testausta.

Clustering and International Competitiveness of Information Technology Industry in the Saint Petersburg Area

The main objective of this study is to assess the potential of the information technology industry in the Saint Petersburg area to become one of the new key industries in the Russian economy. To achieve this objective, the study analyzes especially the international competitiveness of the industry and the conditions for clustering. Russia is currently heavily dependent on its natural resources, which are the main source of its recent economic growth. In order to achieve good long-term economic performance, Russia needs diversification in its well-performing industries in addition to the ones operating in the field of natural resources. The Russian government has acknowledged this and started special initiatives to promote such other industries as information technology and nanotechnology. An interesting industry that is basically less than 20 years old and fast growing in Russia, is information technology. Information technology activities and markets are mainly concentrated in Russia’s two biggest cities, Moscow and Saint Petersburg, and areas around them. The information technology industry in the Saint Petersburg area, although smaller than Moscow, is especially dynamic and is gaining increasing foreign company presence. However, the industry is not yet internationally competitive as it lacks substantial and sustainable competitive advantages. The industry is also merely a potential global information technology cluster, as it lacks the competitive edge and a wide supplier and manufacturing base and other related parts of the whole information technology value system. Alone, the industry will not become a key industry in Russia, but it will, on the other hand, have an important supporting role for the development of other industries. The information technology market in the Saint Petersburg area is already large and if more tightly integrated to Moscow, they will together form a huge and still growing market sufficient for most companies operating in Russia currently and in the future. Therefore, the potential of information technology inside Russia is immense.

Proportionality and Party Success in Europe

This thesis consists of four articles and an introductory section. The main research questions in all the articles are about proportionality and party success in Europe, at European, national or district levels. Proportionality in this thesis denotes the proximity of seat shares parties receive compared to their respective vote shares, after the electoral system’s allocation process. This proportionality can be measured through numerous indices that illustrate either the overall proportionality of an electoral system or a particular election. The correspondence of a single party’s seat shares to its vote shares can also be measured. The overall proportionality is essential in three of the articles (1, 2 and 4), where the system’s performance is studied by means of plots. In article 3, minority party success is measured by advantage-ratios that reveal single party’s winnings or losses in the votes to seat allocation process. The first article asks how proportional are the European parliamentary (EP) electoral systems, how do they compare with results gained from earlier studies and how do the EP electoral systems treat different sized parties. The reasons for different outcomes are looked for in explanations given by traditional electoral studies i.e. electoral system variables. The countries studied (EU15) apply electoral systems that vary in many important aspects, even though a certain amount of uniformity has been aspired to for decades. Since the electoral systems of the EP elections closely resemble the national elections, the same kinds of profiles emerge as in the national elections. The electoral systems indeed treat the parties differentially and six different profile types can be found. The counting method seems to somewhat determine the profile group, but the strongest variables determining the shape of a countries’ profile appears to be the average district magnitude and number of seats allocated to each country. The second article also focuses on overall proportionality performance of an electoral system, but here the focus is on the impact of electoral system changes. I have developed a new method of visualizing some previously used indices and some new indices for this purpose. The aim is to draw a comparable picture of these electoral systems’ changes and their effects. The cases, which illustrate this method, are four elections systems, where a change has occurred in one of the system variables, while the rest remained unchanged. The studied cases include the French, Greek and British European parliamentary systems and the Swedish national parliamentary system. The changed variables are electoral type (plurality changed to PR in the UK), magnitude (France splitting the nationwide district into eight smaller districts), legal threshold (Greece introducing a three percent threshold) and counting method (d’Hondt was changed to modified Sainte-Laguë in Sweden). The radar plots from elections after and before the changes are drawn for all country cases. When quantifying the change, the change in the plots area that is created has also been calculated. Using these radar plots we can observe that the change in electoral system type, magnitude, and also to some extent legal threshold had an effect on overall proportionality and accessibility for small parties, while the change between the two highest averages counting method had none. The third article studies the success minority parties have had in nine electoral systems in European heterogeneous countries. This article aims to add more motivation as to why we should care how different sized parties are treated by the electoral systems. Since many of the parties that aspire to represent minorities in European countries are small, the possibilities for small parties are highlighted. The theory of consociational (or power-sharing) democracy suggests that, in heterogeneous societies, a proportional electoral system will provide the fairest treatment of minority parties. The OSCE Lund Recommendations propose a number of electoral system features, which would improve minority representation. In this article some party variables, namely the unity of the minority parties and the geographical concentration of the minorities were included among possible explanations. The conclusions are that the central points affecting minority success were indeed these non-electoral system variables rather than the electoral system itself. Moreover, the size of the party was a major factor governing success in all the systems investigated; large parties benefited in all the studied electoral systems. In the fourth article the proportionality profiles are again applied, but this time to district level results in Finnish parliamentary elections. The level of proportionality distortion is also studied by way of indices. The average magnitudes during the studied periodrange from 7.5 to 26.2 in the Finnish electoral districts and this opens up unequal opportunities for parties in different districts and affects the shape of the profiles. The intra-country case allows the focus to be placed on the effect of district magnitude, since all other electoral systems are kept constant in an intra-country study. The time span in the study is from 1962 to 2007, i.e. the time that the districts have largely been the same geographically. The plots and indices tell the same story, district magnitude and electoral alliances matter. The district magnitude is connected to the overall proportionality of the electoral districts according to both indices, and the profiles are, as expected, also closer to perfect proportionality in large districts. Alliances have helped some small parties to gain a much higher seat share than their respective vote share and these successes affect some of the profiles. The profiles also show a consistent pattern of benefits for the small parties who ally with the larger parties.

Maritime transportation in the Gulf of Finland in 2007 and in 2015

The Gulf of Finland is said to be one of the densest operated sea areas in the world. It is a shallow and economically vulnerable sea area with dense passenger and cargo traffic of which petroleum transports have a share of over 50 %. The winter conditions add to the risks of maritime traffic in the Gulf of Finland. It is widely believed that the growth of maritime transportation will continue also in the future. The Gulf of Finland is surrounded by three very different national economies with, different maritime transportation structures. Finland is a country of high GDP/per capita with a diversified economic structure. The number of ports is large and the maritime transportation consists of many types of cargoes: raw materials, industrial products, consumer goods, coal and petroleum products, and the Russian transit traffic of e.g. new cars and consumer goods. Russia is a large country with huge growth potential; in recent years, the expansion of petroleum exports has lead to a strong economic growth, which is also apparent in the growth of maritime transports. Russia has been expanding its port activities in the Gulf of Finland and it is officially aiming to transport its own imports and exports through the Russian ports in the future; now they are being transported to great extend through the Finnish, Estonian and other Baltic ports. Russia has five ports in the Gulf of Finland. Estonia has also experienced fast economic growth, but the growth has been slowing down already during the past couples of years. The size of its economy is small compared to Russia, which means the transported tonnes cannot be very massive. However, relatively large amounts of the Russian petroleum exports have been transported through the Estonian ports. The future of the Russian transit traffic in Estonia looks nevertheless uncertain and it remains to be seen how it will develop and if Estonia is able to find replacing cargoes if the Russian transit traffic will come to an end in the Estonian ports. Estonia’s own import and export consists of forestry products, metals or other raw materials and consumer goods. Estonia has many ports on the shores of the Gulf of Finland, but the port of Tallinn dominates the cargo volumes. In 2007, 263 M tonnes of cargoes were transported in the maritime traffic in the Gulf of Finland, of which the share of petroleum products was 56 %. 23 % of the cargoes were loaded or unloaded in the Finnish ports, 60 % in the Russian ports and 17 % in the Estonian ports. The largest ports were Primorsk (74.2 M tonnes) St. Petersburg (59.5 M tonnes), Tallinn (35.9 M tonnes), Sköldvik (19.8 M tonnes), Vysotsk (16.5 M tonnes) and Helsinki (13.4 M) tonnes. Approximately 53 600 ship calls were made in the ports of the Gulf of Finland. The densest traffic was found in the ports of St. Petersburg (14 651 ship calls), Helsinki (11 727 ship calls) and Tallinn (10 614 ship calls) in 2007. The transportation scenarios are usually based on the assumption that the amount of transports follows the development of the economy, although also other factors influence the development of transportation, e.g. government policy, environmental aspects, and social and behavioural trends. The relationship between the development of transportation and the economy is usually analyzed in terms of the development of GDP and trade. When the GDP grows to a certain level, especially the international transports increase because countries of high GDP produce, consume and thus transport more. An effective transportation system is also a precondition for the economic development. In this study, the following factors were taken into consideration when formulating the future scenarios: maritime transportation in the Gulf of Finland 2007, economic development, development of key industries, development of infrastructure and environmental aspects in relation to maritime transportation. The basic starting points for the three alternative scenarios were: • the slow growth scenario: economic recession • the average growth scenario: economy will recover quickly from current instability • the strong growth scenario: the most optimistic views on development will realize According to the slow growth scenario, the total tonnes for the maritime transportation in the Gulf of Finland would be 322.4 M tonnes in 2015, which would mean a growth of 23 % compared to 2007. In the average growth scenario, the total tonnes were estimated to be 431.6 M tonnes – a growth of 64 %, and in the strong growth scenario 507.2 M tonnes – a growth of 93%. These tonnes were further divided into petroleum products and other cargoes by country, into export, import and domestic traffic by country, and between the ports. For petroleum products, the share of crude oil and oil products was estimated and the number of tanker calls in 2015 was calculated for each scenario. However, the future development of maritime transportation in the GoF is dependent on so many societal and economic variables that it is not realistic to predict one exact point estimate value for the cargo tonnes for a certain scenario. Plenty of uncertainty is related both to the degree in which the scenario will come true as well as to the cause-effect relations between the different variables. For these reasons, probability distributions for each scenario were formulated by an expert group. As a result, a range for the total tonnes of each scenario was formulated and they are as follows: the slow growth scenario: 280.8 – 363 M tonnes (expectation value 322.4 M tonnes)
