Pulse Awarded NOV Contract for Monitoring System

Pulse Structural Monitoring (Pulse), an Acteon company, has been awarded a contract with National Oilwell Varco (NOV) Arendal in Norway to provide an acoustic mooring line subsea monitoring system to measure mooring line inclination and tension.

The contract is for 12 mooring line subsea monitoring sensors and ancillary topside equipment, which have been enhanced to meet specific client requirements. The equipment will be installed in the North Sea.

Eivind Vethe, business development manager, Pulse, said, “Our on-going focus on reliability, combined with maintaining excellent client relationships, has resulted in a significant contract with NOV, which represents an important addition to the Pulse project portfolio. With our established and proven technology and products, Pulse delivers reliable and cost-efficient solutions for global oil and gas operators.”

The Pulse system consists of 12 ROV deployable INTEGRIpodTM acoustic data loggers on the mooring line’s upper section to measure actual inclinations. The MoorASSURETM software then regenerates the angles to corresponding tension and horizontal displacement, as well as presence detection of the line. The mooring line sensor array is acoustically linked to an innovative acoustic receiver’s arrangement in the hull of the ship. Calculated data is communicated back to the NOV control system and ship control room.
