HAMPSHIRE, UK – SOFEC Inc. has contracted BMT and Sonardyne Inc., under their teaming agreement, to supply a mooring monitoring system for Eni’s Coral South floating liquefied natural gas (FLNG) project offshore Mozambique.

SOFEC, a MODEC Group company, is supplying the turret mooring system for the FLNG vessel under an EPC contract with a joint venture between TechnipFMC and JGC Corp.

Currently under construction at Samsung Heavy Industries shipyard in Geoje Island, South Korea, the FLNG facility will be designed to produce 3.4 MTPA of LNG and will be moored in 2,000 m (6,562 ft) of water in Mozambique’s Area 4.

Above the waterline, BMT will supply the station-keeping turret monitoring system and local control panel with touchscreen interface. The control panel will also house Sonardyne’s topsides equipment, to minimize the system’s footprint. Additionally, the system will allow SOFEC’s client to gain remote data access through BMT’s secure cloud-based portal, BMT DEEP.

Below the waterline, Sonardyne’s SMART (Subsea Monitoring, Analysis and Reporting Technology) will be used to constantly monitor mooring integrity on each of the 20 anchor legs. Daily summary reports and automatic fault detections will be wirelessly communicated to the surface in real time.

Stephen Auld, global business manager, Subsea Asset Monitoring, Sonardyne, said: “Our SMARTs use fast burst and highly energy efficient acoustic telemetry, as well as ultra-low power electronics, reducing through-life costs for customers... For this project, we’ve also increased the time between battery replacement to in excess of six years, so it’s a long-life, easy to use system to ensure integrity data acquisition.”
