2H Offshore Provides Mooring Line Monitoring System for SBM Offshore

July 24, 2009 at 12:02 am Leave a comment

2H Offshore recently supplied a real-time acoustic mooring line monitoring system called MOORASSURE™ to SBM Offshore. The monitoring system has been successfully deployed on the FPSO Espirito Santo located in the BC-10 field offshore Brazil and was fully commissioned in May 2009.

The Espirito Santo FPSO consists of a subsea turret anchored with nine mooring lines, each with an acoustically linked inclinometer attached to the chain hawse to measure the inclination of the mooring line. The accompanying data logger features onboard memory storage of the data provided by the tri-axial inclination sensors. It has a battery life of five years and features full acoustic communication.

The measured inclination is transmitted from all the 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 users, allowing them to make informed conclusions about how the mooring lines are performing.

In addition to the mooring line monitoring facility, polyester line creep can be evaluated, enabling users to calculate the length of mooring line that needs to be reeled back in order to restore target tensions.
