Improve the accuracy of liquid level measurements by providing guidance on selecting the right location for sensors and the appropriate sampling interval; provide practical solutions for analyzing liquid level measurements.
The objectives of this study are: To provide a review of subsea processing equipment available in industry and identify uncertainties and challenges related to these technologies.
To perform a risk assessment and evaluate additional implications and risks imposed by applying subsea processing equipment.
This project had been cancelled by mutual agreement between the OTRC and MMS.
The primary purpose of the project was to develop and document design guidance for composite production risers based upon the results of the Comparative Risk Analysis (CRA) of Steel and Composite Risers and other recent industry experiences with composite risers. Design guidance focuses on the design considerations that are unique to composite risers, while incorporating the established design and analysis procedures for metallic risers.
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.
The main objective of this project was to investigate severe slugging occurrence, prediction and elimination thoroughly for ultra deep-water production systems and develop a novel approach for the elimination.
In deeper waters, well fluids must travel longer distances (both horizontally and vertically), to reach offshore treatment facilities. The ability to boost (or pump) these untreated fluids has the potential to increase ultimate recovery and accelerate production. Multiphase pumps have become a mature technology onshore, but there is still little experience with their use offshore. This JIP was aimed at developing a tool to support the selection of cost-optimum solutions and maintenance strategies for subsea multiphase boosting in deepwater.
This is a continuation of TAP Project #239 with additional JIP members enrolled. Additional data will be gathered to fill in the gaps of the modeling done in the 1st project (239). The project will now analyze the expanded study of all multiphase flowlines. Earlier phases of the project have been completed
For the safety of an FPSO in survival conditions, it is important to accurately predict any extreme response and the maximum mooring tension during a storm. This study will examine a mooring/riser dynamic analysis program and compare its predictions with OTRC experiments.
Experimental and theoretical work developed explicit models for predicting effects of Viscoelasticity and time-dependent damage on deformation and damage response of composite coiled tubulars. The experimental work used viscoelastic property tests (creep, recovery and constant rate) on composite tubes and uniaxial specimens cut from tubes.
