1. Structural Analysis of the Double Bottom Structure During Ship Grounding by Finite Element Approach
Abstract Possibility of a water-transportation mode to experience numerous accidental loads is predicted limitless and always demand sustainable analysis. Impact phenomenon raises as main reason of environmental damage, for instance, grounding contributes in form of short-time impact and produces massive damage on the bottom structure of a marine vessels, e.

2. Numerical Simulation for the Collision Between Side Structure and Level Ice in Event of Side Impact Scenario
Abstract With the opening of the Northern Sea for international shipping routes, various vessels prefer to use this option to reach Europe as distance is significantly reduced if a ship is sailing through this route. In the same time, the demand to ensure ship safety rises as impact phenomenon between ship structures and ice causes numerous casualties. This

3. Alternativas de tratamento da água de lastro em portos exportadores de minério de ferro. / Ballast water treatment alternatives in the iron ore ports exporting.
This thesis aims at making a technical and economic analysis of the ballast water treatment in Brazilian iron ore ports. Three distinct treatment alternatives were studied: (1) onshore ballast water treatment; (2) water desalination plant to ballast water treatment; (3) onboard ballast water treatment in shuttle tanker vessels operating in the mooring, where

4. Application of Bayesian Networks in the human error contribution analysis of collision accidents. / Aplicação de Redes Bayesianas na análise da contribuição do erro humano em acidentes de colisão.
Recently, in the naval industry, the normalization of classification societies and IMO (International Maritime Organization) has presented a gradual change, going from prescriptive procedures to a regulatory structure based on risk. That perspective offers some advantages to operators and constructors: 1) greater capacity to incorporate innovations in design

5. Sorção de petróleo por fibras vegetais
Nowadays, when accidents with oil tanker or shore tanks occur and there is oil spill, some arrangements are made in order to repress and to fix the situation. For the containment, barriers or detours are usually made of synthetic materials such as polyurethane foam. In order to clear water away, techniques like in loco burning, biodegradant agents, dispersan

6. Estudo da influência dos efeitos de interação hidrodinâmicos em operações de alívio auxiliadas por sistemas DP. / An study about the influence of the hydrodynamic interaction effects in offloading DP operations.
Hoje em dia, a maioria das operações de alívio é feita utilizando um sistema de posicionamento dinâmico (DP). O sistema DP permite controlar a posição relativa entre o navio aliviador e o FPSO (Floating Production Storage and Offloading), trazendo desta forma muitas vantagens à operação. Neste tipo de operação os dois corpos flutuantes precisam f

7. Técnica de otimização multiobjetivo aplicada ao projeto preliminar de navios petroleiros. / Multi-objective optimization technique applied to preliminary design of a tanker.
Este trabalho apresenta um processo racional para a seleção das dimensões e coeficientes de forma ótimos para um navio petroleiro usando a técnica dos algoritmos genéticos. É proposto um procedimento para balanceamento em função do peso e espaço disponível de carga, determinando sua viabilidade e permitindo balancear navios de peso ou de volume. A

8. Adaptive techniques applied to offshore dynamic positioning systems
Dynamic positioning systems (DPS) comprise the deployment of active propulsion to maintain the position and heading of a vessel. Several sensors are used to measure the actual position of the floating body, while a control algorithm is responsible for the calculation of forces to be delivered by each propeller, in order to counteract all environmental forces

9. A indústria de construção naval: uma abordagem estratégica. / The shipbuilding industry: a strategic approach.
The strategic approach of any industry is grounded on the knowledge of the mechanisms which regulate the competition within this industry. The players, based on reason or not, try to achieve an advantageous position relative to the others, so as to take competitive advantages, which implies in superior profits. Therefore, it is necessary to formulate a strat

10. Educación ambiental en tiempos de catástrofe: la respuesta educativa al naufragio del Prestige
In November 2002, the Prestige, an obsolete oil tanker, sank and spilled her cargo offshore Galicia (in the northwest of the Iberian Peninsula). This accident originated a social experiment, unwanted but valuable to understand how the catastrophic experience of the "manufactured risks" is socially represented. The present article analyzes the response of the

11. REQUIRED TANKER FLEET FOR OIL PRODUCTS DISTRIBUTION IN AN URBAN OPERATION IN BRAZIL / FROTA NECESSÁRIA A UMA OPERAÇÃO DE DISTRIBUIÇÃO DE DERIVADOS DE PETRÓLEO
Esta dissertação apresenta um estudo sobre a Logística de Distribuição de Derivados de Petróleo, com o desenvolvimento de um modelo para a determinação do tamanho mínimo da frota rodoviária necessária a uma operação de distribuição. Esse modelo, implementado através de uma heurística, não se propõe a determinar o tamanho ótimo da frota e
