In this paper we intend to present the advantages of the double hull projects and to show how double hulled tankers are considered to be more secure in case of grounding especially if the soil is not too rocky.

The objective of the present research is to study the ultimate strength of ship’s hull considering cross section and beam finite element under longitudinal bending. The single hull bulk carrier and double hull oil tanker are taken to be analysed. The one-frame space of ship is considered in the calculation. The cross section of ship’s hull is divided into element composed plate and stiffened plate. The cross section is assumed to be remained plane and the simply supported is imposed to both side of the cross section. The longitudinal bending moment is applied to the cross section for hogging and sagging condition. The Smith’s method is adopted and implemented into the in-house program of the cross section and beam finite element to calculate the ultimate strength of ship’s hull. The result of the ultimate strength for hogging and sagging condition obtained by considering the cross section and beam finite element is compared with one another.

Double Hull

FPSOs are often converted from, and carry ship safety certification as, oil tankers. The two types of ship have been reasonably compatible until passage in early 1992 of new international requirements for tankers to be constructed or converted to double hull requirements and for existing vessels to be phased out when they have been in service for 25 to 30 years. Such requirements, which have become increasingly onerous since 1973, are based on the hazards involved in navigation of oil tankers and do not reflect the risks applying to FPSO operations.In cooperation with the Australian offshore industry, AMSA made a number of submissions to the International Maritime Organisation (IMO), seeking clarification on whether FPSOs should be subjected to the rules for oil tankers. To cover the possibility that it is confirmed that FPSOs should comply with the rules, the submission proposed modifications to those rules to reflect the FPSO operating environment.The submissions resulted in IMO deciding, in March 1993, that although FPSOs would continue to be treated as oil tankers, they would not be required to comply with the double hull requirements which could have necessitated their withdrawal from service upon reaching 30 years of age.Achievement of a successful conclusion to this project has involved a cooperative effort between AMSA and the offshore oil and gas industry.

In recent decades, the safety of ships at sea has become a major concern of the global maritime industries. Ships are rarely subject to severe accidents during their life cycle. Collision is one of the most hazardous accidents, with potentially serious consequences such as the loss of human life, structural damage and environmental damage, especially if large tankers, LNG and/or nuclear-powered vessels are involved. This study presents a Quantitative Risk Assessment (QRA) for double hull oil tankers that have collided with different types of ships. The methodology used to perform the QRA is based on the International Maritime Organization’s (IMO) definition of a Formal Safety Assessment (FSA). Using probabilistic approaches, ship-ship collision scenarios are randomly selected to create a representative sample of all possible scenarios. The collision frequency is then calculated for each scenario. As this is a virtual experiment, the LS-DYNA nonlinear finite element method (NLFEM) is used to predict the structural consequences of each scenario selected. In addition, the environmental consequences are estimated by calculating the size of each scenario’s oil spill. To assess the economic consequences, the property and environmental damages are calculated in terms of monetary units. The total risk is then calculated as the sum of the resultant structural and environmental damages. Exceedance curves are established that can be used to define the collision design loads in association with various design criteria.
