Mooring System Design Considerations

/
A permanently moored Floating Production Unit has a complex mooring system with many constraints. A wide variety of factors must be considered to try to predict the future and account for degradation of the system.

Testing SAMIR Update

SAMIR (Semi-Autonomous Mooring Inspection Robot) testing is continuing with excellent results so far; we are getting the system ready for the offshore trial scheduled later this year.

How to assess the risk of mooring failure in a Floating Production system

/
Published in 2008, the Oil and Gas UK (O&G UK) Mooring Integrity Guidance is used by much of the industry to develop and implement an effective risk management strategy. The “risk” associated with mooring failure is a combination of consequence and likelihood of specific events.

What is mooring failure?

/
The primary objective of a mooring system is to maintain vessel position to protect the risers and prevent collision with nearby infrastructure. So at what point is a mooring system considered to have failed: single line failure, two line failure, or at the point of collision or riser failure?
