A comparative benchmarking analysis of main Iberian container terminals: a DEA approach

Benchmarking is an important tool to organisations to improve their productivity, product quality, process efficiency or services. From Benchmarking the organisations could compare their performance with competitors and identify their strengths and weaknesses. This study intends to do a benchmarking analysis on the main Iberian Sea ports with a special focus on their container terminals efficiency. To attain this, the DEA (data envelopment analysis) is used since it is considered by several researchers as the most effective method to quantify a set of key performance indicators. In order to reach a more reliable diagnosis tool the DEA is used together with the data mining in comparing the sea ports operational data of container terminals during 2007.Taking into account that sea ports are global logistics networks the performance evaluation is essential to an effective decision making in order to improve their efficiency and, therefore, their competitiveness.

Energy Consumption and Efficiency: Emerging Challenges from Reefer Trade in South American Container Terminals

This issue of the FAL Bulletin discusses the relevance of energy consumption as a basis for identifying energy efficiency potential and calculating the carbon footprints of ports and terminals in Latin America and the Caribbean (LAC), focusing on the Southern Cone countries of Argentina, Chile, Paraguay and Uruguay.

Asset productivity at container terminals in Latin America and the Caribbean: 2005-2013

This issue of the FAL Bulletin shows productivity trends at container terminals in Latin America and the Caribbean during the period from 2005 to 2013, comparing them to the trend of earlier years (2000 to 2004). One of the conclusions of the study is that most terminals in the region have improved their quay productivity in recent years, although there are large differences between the three container terminal size categories analysed. However, the author identifies a number of challenges still to be met at the region’s ports.

Berth Management in Container Terminals: Quality of Service

This paper empirically evaluates container terminal service attributes. The methodology proposed focuses on statistical control. Based on the concept of service segmentation, the authors employed control charts to classify container terminal services. The purpose of control charts is to allow simple detection of events that are indicative of actual process change. This simple decision can be difficult where the process characteristic is continuously varying, the control chart provides statistically objective criteria of change. When change is detected and considered good its cause should be identified and possibly become the new way of working, where the change is bad then its cause should be identified and eliminated. Both theoretical and practical implications of the research findings are discussed in this paper.

A methodology proposal to obtain operational parameter forecasts and operational risk assessment in container terminals

Las terminales de contenedores son sistemas complejos en los que un elevado número de actores económicos interactúan para ofrecer servicios de alta calidad bajo una estricta planificación y objetivos económicos. Las conocidas como "terminales de nueva generación" están diseñadas para prestar servicio a los mega-buques, que requieren tasas de productividad que alcanzan los 300 movimientos/ hora. Estas terminales han de satisfacer altos estándares dado que la competitividad entre terminales es elevada. Asegurar la fiabilidad de las planificaciones del atraque es clave para atraer clientes, así como reducir al mínimo el tiempo que el buque permanece en el puerto. La planificación de las operaciones es más compleja que antaño, y las tolerancias para posibles errores, menores. En este contexto, las interrupciones operativas deben reducirse al mínimo. Las principales causas de dichas perturbaciones operacionales, y por lo tanto de incertidumbre, se identifican y caracterizan en esta investigación. Existen una serie de factores que al interactuar con la infraestructura y/o las operaciones desencadenan modos de fallo o parada operativa. Los primeros pueden derivar no solo en retrasos en el servicio sino que además puede tener efectos colaterales sobre la reputación de la terminal, o incluso gasto de tiempo de gestión, todo lo cual supone un impacto para la terminal. En el futuro inmediato, la monitorización de las variables operativas presenta gran potencial de cara a mejorar cualitativamente la gestión de las operaciones y los modelos de planificación de las terminales, cuyo nivel de automatización va en aumento. La combinación del criterio experto con instrumentos que proporcionen datos a corto y largo plazo es fundamental para el desarrollo de herramientas que ayuden en la toma de decisiones, ya que de este modo estarán adaptadas a las auténticas condiciones climáticas y operativas que existen en cada emplazamiento. Para el corto plazo se propone una metodología con la que obtener predicciones de parámetros operativos en terminales de contenedores. Adicionalmente se ha desarrollado un caso de estudio en el que se aplica el modelo propuesto para obtener predicciones de la productividad del buque. Este trabajo se ha basado íntegramente en datos proporcionados por una terminal semi-automatizada española. Por otro lado, se analiza cómo gestionar, evaluar y mitigar el efecto de las interrupciones operativas a largo plazo a través de la evaluación del riesgo, una forma interesante de evaluar el effecto que eventos inciertos pero probables pueden generar sobre la productividad a largo plazo de la terminal. Además se propone una definición de riesgo operativo junto con una discusión de los términos que representan con mayor fidelidad la naturaleza de las actividades y finalmente, se proporcionan directrices para gestionar los resultados obtenidos. Container terminals are complex systems where a large number of factors and stakeholders interact to provide high-quality services under rigid planning schedules and economic objectives. The socalled next generation terminals are conceived to serve the new mega-vessels, which are demanding productivity rates up to 300 moves/hour. These terminals need to satisfy high standards because competition among terminals is fierce. Ensuring reliability in berth scheduling is key to attract clients, as well as to reduce at a minimum the time that vessels stay the port. Because of the aforementioned, operations planning is becoming more complex, and the tolerances for errors are smaller. In this context, operational disturbances must be reduced at a minimum. The main sources of operational disruptions and thus, of uncertainty, are identified and characterized in this study. External drivers interact with the infrastructure and/or the activities resulting in failure or stoppage modes. The later may derive not only in operational delays but in collateral and reputation damage or loss of time (especially management times), all what implies an impact for the terminal. In the near future, the monitoring of operational variables has great potential to make a qualitative improvement in the operations management and planning models of terminals that use increasing levels of automation. The combination of expert criteria with instruments that provide short- and long-run data is fundamental for the development of tools to guide decision-making, since they will be adapted to the real climatic and operational conditions that exist on site. For the short-term a method to obtain operational parameter forecasts in container terminals. To this end, a case study is presented, in which forecasts of vessel performance are obtained. This research has been entirely been based on data gathered from a semi-automated container terminal from Spain. In the other hand it is analyzed how to manage, evaluate and mitigate disruptions in the long-term by means of the risk assessment, an interesting approach to evaluate the effect of uncertain but likely events on the long-term throughput of the terminal. In addition, a definition for operational risk evaluation in port facilities is proposed along with a discussion of the terms that better represent the nature of the activities involved and finally, guidelines to manage the results obtained are provided.

Scheduling of straddle carriers in a container terminal

Report for the scientific sojourn at the University of California at Berkeley between September 2007 to February 2008. The globalization combined with the success of containerization has brought about tremendous increases in the transportation of containers across the world. This leads to an increasing size of container ships which causes higher demands on seaport container terminals and their equipment. In this situation, the success of container terminals resides in a fast transhipment process with reduced costs. For these reasons it is necessary to optimize the terminal’s processes. There are three main logistic processes in a seaport container terminal: loading and unloading of containerships, storage, and reception/deliver of containers from/to the hinterland. Moreover there is an additional process that ensures the interconnection between previous logistic activities: the internal transport subsystem. The aim of this paper is to optimize the internal transport cycle in a marine container terminal managed by straddle carriers, one of the most used container transfer technologies. Three sub-systems are analyzed in detail: the landside transportation, the storage of containers in the yard, and the quayside transportation. The conflicts and decisions that arise from these three subsystems are analytically investigated, and optimization algorithms are proposed. Moreover, simulation has been applied to TCB (Barcelona Container Terminal) to test these algorithms and compare different straddle carrier’s operation strategies, such as single cycle versus double cycle, and different sizes of the handling equipment fleet. The simulation model is explained in detail and the main decision-making algorithms from the model are presented and formulated.

Container Terminal Simulation. A case study: port of Valencia.

This paper is concerned with the study of non-Markovian queuing systems in container terminals. The methodology presented has been applied to analyze the ship traffic in the port of Valencia located in the Western Mediterranean. Two container terminals have been studied: the public container terminal of NOATUM and the dedicated container terminal of MSC. This paper contains the results of a simulation model based on queuing theory. The methodology presented is found to be effective in replicating realistic ship traffic operations in port as well as in conducting capacity evaluations. Thus the methodology can be used for capacity planning (long term), tactical planning (medium term) and even for the container terminal design (port enlargement purposes).

Deterministic approach for multiple-source tsunami hazard assessment for Sines, Portugal

In this paper, we present a deterministic approach to tsunami hazard assessment for the city and harbour of Sines, Portugal, one of the test sites of project ASTARTE (Assessment, STrategy And Risk Reduction for Tsunamis in Europe). Sines has one of the most important deep-water ports, which has oil-bearing, petrochemical, liquid-bulk, coal, and container terminals. The port and its industrial infrastructures face the ocean southwest towards the main seismogenic sources. This work considers two different seismic zones: the Southwest Iberian Margin and the Gloria Fault. Within these two regions, we selected a total of six scenarios to assess the tsunami impact at the test site. The tsunami simulations are computed using NSWING, a Non-linear Shallow Water model wIth Nested Grids. In this study, the static effect of tides is analysed for three different tidal stages: MLLW (mean lower low water), MSL (mean sea level), and MHHW (mean higher high water). For each scenario, the tsunami hazard is described by maximum values of wave height, flow depth, drawback, maximum inundation area and run-up. Synthetic waveforms are computed at virtual tide gauges at specific locations outside and inside the harbour. The final results describe the impact at the Sines test site considering the single scenarios at mean sea level, the aggregate scenario, and the influence of the tide on the aggregate scenario. The results confirm the composite source of Horseshoe and Marques de Pombal faults as the worst-case scenario, with wave heights of over 10 m, which reach the coast approximately 22 min after the rupture. It dominates the aggregate scenario by about 60 % of the impact area at the test site, considering maximum wave height and maximum flow depth. The HSMPF scenario inundates a total area of 3.5 km2. © Author(s) 2015.

Entitat Metropolitana del Transport. Centre Operatiu d'Autobusos del Prat

El projecte contempla la resolució d’un Centre Operatiu d’Autobusos Metropolitans amb un programa que ha de donar cabuda a un mínim de 300 places d’aparcament de diferents mesures, tallers de manteniment, túnels de neteja, sortidors de repostatge, vestuaris, administració, oficines i serveis generals. L’emplaçament se situa en el barri de Sant Cosme del Prat de Llobregat, en un solar que esdevé la façana d’aquesta població a l’entrada a Barcelona des de l’aeroport. L’entorn el conformen els espais de protecció de les pistes que es perllonguen fins a tocar el Parc Natural del Delta del Llobregat, una zona humida protegida d’àmbit europeu. Al mateix temps, els requeriments del concurs sol•liciten mantenir un 50% de la superfície del solar com a parc urbà. Això comporta abordar la resolució d’un edifici extens, però de 3 alçades i mitja, per tal de poder encabir tot el programa. Tot i així, la proposta integra el gran volum de l’edificació en harmonia compositiva i cromàtica amb el canyissar i manté l’alçària en una cota similar a la dels edificis de l’entorn. L’àrea verda es concentra en la part de la parcel•la que té continuïtat directe amb el pati del nou Esplai del barri, per tal de optimitzar-ne l’ús. Al mateix temps, les àrees de circulació, neteja i manteniment dels autobusos se situen a la part posterior del solar, per fer-les compatibles amb la resta de requeriments funcionals i perquè la volumetria principal doni front a les vies d’entrada a l’àrea metropolitana. La cotxera està continguda en un únic volum lleugerament soterrat, per limitar l’alçària total. La construcció principal, de 120 x 55 x 14,5 metres, es troba configurada per una estructura regular que respecta les mesures i moviments dels autobusos, i per una pell consistent en una gelosia oberta en tres cares, i tancada en l’alçat nord. Aquest tancament es realitza amb prismes verticals de colors similars a la vegetació del entorn, separats harmònicament per tal de dissoldre lleument els contorns del volum. Com a contrapunt a la gran peça principal, es proposa un petit edifici vidriat que indica l’entrada a les oficines i conté les activitats administratives.Les àrees de funcionament es resumeixen en les següents:1. La circulació dels autobusos: el conjunt disposa de tres vies simultànies, una d’accés i dues de sortida, situades en línia amb dos punts de repostatge, aspiració interior i traspàs de dades i recaptacions, aptes per a ser utilitzades per tres vehicles alhora. També es disposen tres túnels de rentat previs a l’entrada a l’interior de la cotxera, amb pas per a tres carrils en by-pass. Es preveu una quarta via especial d’accés i sortida directes al taller, per situacions extraordinàries.2. La circulació dels vehicles de personal: tenen un accés i un recorregut independent al dels autobusos, amb control informatitzat. 3. La entrada peatonal de visites o personal: l’edifici disposa també d’una entrada peatonal que es produeix des de la porta principal, situada en el front del edifici administratiu.4. El edifici principal: consta de diferents nivells. El Nivell 0, a cota –1,3 m. es troba ocupat per la zona d’aparcament de vehicles privats (98 uts), l’aparcament de minibusos (20 uts), el taller d’autobusos (23 uts standard amb ITV, 2 uts articulats, 1 ut pintura articulat, 2 uts reparcions sostres), i l’àrea d’explotació i de dependències per conductors (vestidors, àrea de descans, cafeteria i espais habitables).El Nivell 1, a cota 2,4 m. està ocupat per l’aparcament de 47 autobusos de 13 m. de llarg i per 20 autobusos de 15 m.El Nivell 2, a cota 4,8 m. l’ocupen 22 places d’autobusos de 15 m., 6 places d’articulats i 37 de 13 m.El Nivell 3, a cota 7,2 m. és idèntic al Nivell 1.El Nivell 4, és idèntic al Nivell 2 i permet que la rampa continuï fins a un Nivell 5 de coberta, que excepcionalment pot convertir-se en aparcament descobert de 67 autobusos de més.La proposta contempla amb fermesa criteris de Sostenibilitat. Aquests es centren en primer lloc en la sobrietat del projecte que garanteix una organització clara en quan a circulacions i rendiment del espai i que, per tant, no malbarata més recursos dels necessaris. En segon lloc, s’aprofiten al màxim la llum i la ventilació naturals i, al mateix temps, es genera la pròpia energia per millorar la eficiència. També es resol el re-processament dels residus generats pel complex, es re-aprofiten les aigües utilitzades en els vestuaris i oficines pel rentat dels vehicles, i s’emmagatzemen les aigües pluvials per tal de complementar la generació d’energia i per escalfar amb el sol aigua calenta de neteja. En tercer lloc, es té especial cura en l’impacte ambiental del edifici, procurant adequar-lo a l’estructura urbana tant en alineacions com el alçària. També s’evita la contaminació acústica apantallant el so intern per tal de no enviar-lo a les àrees habitades, s’endrecen els accessos dels autobusos des de la rotonda de la via pública per alterar el mínim el trànsit dels veïns, i es concentra l’àrea verda en la zona on es té més contacte amb l’activitat veïnal comunitària: l’Esplai del barri.

MCDA: análise de decisão multicritério como ferramenta de avaliação de instalações portuárias: o caso dos terminais de contêineres brasileiros

Este trabalho busca avaliar, com suporte da metodologia MCDA - análise de decisão multicritério, os terminais de contêineres brasileiros quanto a suas potencialidades como vetores de crescimento sustentado da economia, no médio e longo prazo, para priorização de investimentos públicos e privados. O trabalho se consubstancia em um levantamento bibliográfico do tema decisório, que lhe serve de base, seguido de um estudo do tema portuário, a fim de levantar os fatores que tornam viável o florescimento e desenvolvimento de um sítio portuário, além de buscar tendências do setor de contêineres no Brasil. Após estas etapas, foi desenvolvido uma modelagem para o problema de avaliação dos terminais, com ajuda do software Expert Choice. Os resultados obtidos apontam para uma alteração sensível de paradigma no panorama portuário nacional em um cenário futuro. Portos que hoje se localizam na parte superior da lista de movimentação de contêineres, à frente nas estatísticas, podem não ter para onde se expandir, enquanto outros, que se encontram menos pujantes, podem florescer nas próximas décadas, devido às características de cada sítio portuário. As mais relevantes foram selecionadas como critérios do modelo desenvolvido, são eles: águas abrigadas, retroáreas, acessos terrestres e marítimos, equacionamento de questões ambientais, localização estratégica, vocação regional, extensão de cais e áreas de expansão. Entre as conclusões deste estudo, pode-se citar: 1 - O Porto de Santos, tradicional líder do ranking nacional em movimentação de contêineres, deve se manter entre os primeiros, graças à sua proximidade com o principal centro econômico e industrial nacional, a região da grande São Paulo, embora esteja com sua capacidade perto do limite operacional, conta com áreas de expansão, como o projeto Barnabé-Bagres. 2 - Outro porto que se destacou na classificação final foi o de Itaguaí, já hoje com movimentação crescente e enorme potencial de crescimento na área de contêineres. Possui excelente condição de águas abrigadas, boa localização estratégica, entre Rio de Janeiro e São Paulo, dois pólos econômicos fortes, com influência decisiva no cenário nacional, e que dispõe de consistente plano de expansão, especialmente relacionado ao aumento de contêineres.

Criterios de calidad del servicio prestado en el ámbito de la línea de atraque de las terminales portuarias de contenedores

Esta Tesis Doctoral evalúa empíricamente la calidad del servicio en la línea de atraque de las terminales portuarias de contenedores. La metodología propuesta utiliza indicadores de calidad y se basa en el concepto de la segmentación de servicio. Para ello se desarrolla la teoría del Control Estadístico de Procesos (CEP) y se utilizan los gráficos de control para clasificar el servicio en las terminales de contenedores. El propósito de la Tesis es proporcionar una metodología basada en el Control Estadístico de Procesos (CEP) para evaluar la calidad del servicio y detectar las escalas de un servicio regular de línea que se encuentran fuera de control. Por tanto, la metodología se puede utilizar para detectar eventos que son indicativos de cambio real del proceso en la línea de atraque. Esta detección puede ser compleja pues las características de los procesos en terminales de contenedores son variables. La metodología proporciona mediante los gráficos de control criterios estadísticamente objetivos de cambio. Cuando el cambio es detectado y considerado bueno sus causas deben ser identificadas y posiblemente convertirse en la nueva forma de trabajar, cuando el cambio es negativo, entonces sus causas deberían ser identificadas y eliminadas. La Tesis Doctoral está organizado de la siguiente manera: La primera parte es la introducción, e incluye los capítulos 1 al 4, la segunda parte presenta el Estado del Arte (capítulo 5) y algunos de los estudios que han inspirado esta investigación, la tercera parte se centra en la metodología utilizada (capítulo 6) y su aplicación sobre un caso de estudio (capítulo 7). Finalmente, en la cuarta parte se presentan las conclusiones y se proponen algunas de las nuevas líneas de investigación que quedan abiertas (capítulo 8). This Thesis empirically evaluates the quality of service in the berthing face of container terminals. The methodology proposed is focused on quality of service indicators and is based on the concept of service segmentation. The Statistical Process Control (SPC) theory and the control charts are used to classify container terminal service. The aim of this Thesis is to provide a methodology based on Statistical Process Control that can evaluate the quality of service and also can detect scales of shipping liner service that are out of control. Therefore, the methodology can be used to detect events that are indicative of real change in the berthing process of container vessels. The methodology proposed allows simple detection of events that are indicative of actual process change in container terminals. This detection is complex because the characteristics of the processes are variable in the container terminals; the control chart provides statistically objective criteria of change. When change is detected and considered good its cause should be identified and possibly become the new way of working, where the change is bad then its cause should be identified and eliminated. This Thesis is organized as follows: The first part is the introduction (includes Chapters 1 to 4), the second part presents the State of the Art (Chapter 5) and some of the studies that have inspired this research. The third part focuses on the methodology used (Chapter 6) and its application to a case study (Chapter 7). Finally, Part 4 presents the conclusions and suggests future research (Chapter 8).
