LONDON -- 2H Offshore has supplied a Moorassure real-time acoustic mooring line monitoring system to SBM Offshore. The system has been successfully deployed on the FPSO Espirito Santo in the BC-10 field off the coast of Brazil and has been fully commissioned since May, the company says.
The Espirito Santo FPSO consists of a subsea turret anchored with nine mooring lines. Each mooring line has anacoustically-linked inclinometer attached to the chain hawse to measure the inclination of the mooring line.
The data logger features onboard memory storage, tri-axial inclination sensors, has a battery life in excess of five years and features full acoustic communication. The measured inclination is transmitted from all mooring lines to three acoustic receivers mounted on the chain table of the turret to achieve cable-free data communication.
Software is able to present historical tension and angle data to the end user, to determine mooring line performance. In addition to the mooring line monitoring facility, polyester line creep can be evaluated, enabling the end user to calculate the length of mooring line that needs to be reeled back in order to restore target tensions, the company says.
