Comparative Risk Analysis of Spar-Based FPSO's

Project was a comparison of risks for a Spar-based FPSO with other deepwater production systems studied in the Comparative Risk Analysis of Deepwater Production Systems in the Gulf of Mexico. Those systems were a tanker-based FPSO with wet trees, a conventional Spar with dry trees, a TLP with dry trees, and a shallow water jacket serving as a hub and host for deepwater production. The spar-based FPSO configuration studied was a spar with wet-oil storage, dry trees, oil export by shuttle tanker and a gas export by pipeline.

FPSO Roll Motions

Investigate the effect of the location and extent of the bilge keels on the motions of an FPSO hull and assess its effectiveness in mitigating roll motions. Develop a computationally efficient finite volume method to study the unsteady flow around a 2-D hull section subject to roll motions with or without bilge keels. Evaluate the motions of an FPSO hull in the absence of the bilge keels (WAMIT).

An International Workshop on Fire and Blast Engineering for the Offshore Industry

This project will organize and facilitate a two-day international workshop on fire and blast engineering in June 2002. This meeting will work on the initiatives that have begun to update existing API guidance relating to Fire and Blast to include technological advancements over the last 10 years to encompass deepwater, floating and moored structures. Seven working groups will be used at this meeting and are as follows:

Interim Damage Criteria for Replacing Damaged Polyester Rope

BP EXPLORATION, Upstream Technology Group has requested that Stress Engineering Services (SES), perform a set of tests and analyses to develop an interim criteria for replacing damaged polyester mooring rope. BP and SES recognize that the Offshore Technology Research Center (OTRC) is developing a more thorough, longer-term project on the same subject, funded in part by the Minerals Management Service (MMS). BP believes it will have Gulf of Mexico applications for polyester rope taut line mooring systems before a criterion is available.
