Development of a New Concept of Multimission Pollution Control Vessel and Optimization of its Bulbous Bow

Abstract

Controlling marine pollution caused by hydrocarbons spilling from oil tanker accidents and oil rigs is urgently needed. Conventional pollution control vessels currently in service worldwide do not meet certain safety criteria, storage capacities, and response times owing to their technical shortcomings. This study proposes a new concept of multimission and autonomous antipollution vessels capable of acting quickly and efficiently to counter such pollution threats. The objective of this study is to carry out a total and rapid recovery of the spilled oil slick in complete safety. Hence, optimizing the bulbous bow adapted to the pollution control vessel during its displacement is necessary to horizontally straighten the accompanying waves formed around the hull and to laminate the flow upstream of the side openings for the recovery of spilled oil. This optimization improves the nautical qualities specific to this ship to reduce the total resistance to progress and to standardize the flow upstream of the side openings to allow the collection of spilled oil at high speed. This optimization study can open a field of application for the construction of modern multi-mission pollution control vessels. Tests in hull basins will be planned to validate and adjust the results obtained from the simulations.
