HOUSTON -- APL Offshore Singapore has awarded First Subsea a contract to supply four diverless bend stiffener connectors for two STL buoys destined for the Neptune LNG deepwater project North and South.
The submerged turret loading (STL) buoys will be used for mooring LNG regasification vessels at the offshore processing Neptune deepwater port. The diverless bend stiffeners for each of the STL buoy's gas offloading riser and umbilical will comprise First Subsea diverless bend stiffener connectors (DBSC) and Trelleborg CRP bend stiffeners. They will be used for gas risers and umbilicals carrying hydraulic and power lines.
The DBSC uses First Subsea's Ballgrab ball and taper technology where female DBSC connectors are integrated into the STL buoy ahead of tow out. The DBSC male connectors are then inserted offshore to provide a secure connection for a gas offloading riser bend stiffener within a J tube and an umbilical within an I tube on each of the buoys. The risers and umbilicals are secured at the top of each respective I/J tube.
Final delivery of APL's buoy system is expected in May 2009 and the installation campaign will begin soon after.
