To develop a draft API document that includes important inspection related issues concerning maintenance practices on fixed platforms.
The primary objective of this research project is to identify and measure significant noise sources, paths and radiators generated from shallow water drilling and production operations on a gravel island in the Alaskan Beaufort Sea and to determine and recommend the most effective treatment for each source type. Knowing the equipment currently being used on a gravel island that is conducting drilling and production operations, what could be done to decrease the radiated noise entering the environment?
This project evaluated new and / or improved repair techniques for ageing or damaged structures, such as clamps, underwater welding, use of composite techniques, liners, member replacement or the use of ROVs in repair operations.

This project used the WINPOST program (a hull/mooring/riser nonlinear coupled dynamic analysis in the time domain), and will included all hydrodynamic interaction effects.
Project includes several efforts related to improving the understanding of ocean turbulence and how to predict its effect on offshore structures, particularly Spars; Collaborate with DeepStar on planning of a field measurement program to gather data on ocean turbulence and on use of DeepStar experimental test data to validate a CFD model of turbulent flow interactions with a Spar platform. Collaborate with design and analysis of CFD experiments to study the effect of ocean turbulence on Vortex-Induced Motions of Spar platforms.
Effect of ocean turbulence on the hydrodynamic forces is currently an important issue for offshore installations in the GOM. The two focus areas are; 1 - completion of the CFD study in 2-D of the effect of upstream turbulence on the hydrodynamic forces exerted on cylinders, and 2 - study of the effect of upstream turbulence using 3-D CFD simulations. The project developed techniques for the simulating prescribed turbulence structures in the upstream flow field, as well as on simulations of flows around cylinders with and without turbulence being present in the current profile.
Cooperative project with OTRC on VIM/SPAR Industry Forum. The workshop forum led to sharing data and experiences that have been gained to date. Focus on objectives as follows: Initiate a path for development of an industry-acceptable design practice/ methodology on Spar VIM; Identify uncertainties and technical needs in Spar VIM and a path forward to fill the identified gaps;
Educate industry on the technical challenges involved.
Project is a JIP with industry and is to develop engineering methodology and risk model for the analysis of submarine slope stability under critical loading conditions. This project is an extension of project 404, Offshore Deep Slopes (PODS) is named Phase II of the earlier project (404). Phase II of the study focused on physical and numerical modeling aspects. Additionally, results were analyzed, along with further development of a risk framework suited to the offshore environment.
Project will study failures of offshore drilling rigs, MODUs, Jackup Rigs associated with the passage of Hurricane Lili in the autumn of 2002. Develop any recommendations updates on criteria, review data from the Hurricane Andrew timeframe and the make recommendations to SNAME RP for possible future mitigation action.
