AMOG

PROJECT NAME: Offshore mooring Chain Failure 

Brief Introduction:

The Offshore Oil industry relies on mooring systems which includes chains, mooring lines and connectors to fix offshore floating platforms and other vital equipment to the floating platform and sea bed. The integrity of a mooring system is essential to prevent any major failure; the potential results being damage to equipment or a major pollution incident. In this case an offshore mooring chain failed short of its intended life. The catastrophic failure in the mooring chain resulted in litigation between the designer of the mooring chain and the asset owner of the offshore platform.

Client: AMOG Consulting

Objective: To provide subject matter expert advice for a lawsuit between the designer of a mooring chain and the asset owner of the offshore platform.
