Troubleshooting a complex offshore system based on technical evaluation and integrity assessments - case study of module handling system
MetadataVis full innførsel
The offshore industry is seeing the advent of new technologies and complex systems as it ventures into harsher and more remote locations. Integrity and reliability are the keys to such systems. It is critical to technically evaluate these complex systems thoroughly and modify them to meet the harsh challenges they have to withstand. The already existing mobile assets also have to be studied and recertified to meet the higher load conditions of rougher seas. The module handling system (MHS) is a complex system which could handle up to 60Te of subsea modules at 4.5Hs making it versatile system in the North Sea subsea market. The MHS has various structural, electrical, mechanical, hydraulic, control subsystems which have to be upgraded and properly interfaced to meet the requirements. The main objective of this thesis is to evaluate the system by studying all the subsystems in detail and providing with solutions / recommendations for improving the reliability. Various areas of improvement have been identified. Recommendations provided for the improvements of the systems are generic and could be used in the asset management in the offshore industry.
