Abstract

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.
