Deepwater mooring specialist, First Subsea, has completed the installation of subsea mooring connectors for Anadarko Petroleum's Heidelberg truss spar platform moored in 5310ft (1620m) of water in field development in the Gulf of Mexico.
The 23,000-ton spar has been moored by nine Series III Ballgrab ball and taper mooring connectors attached to polyester mooring lines. The connector's male mandrels are manufactured in compliance with American Bureau of Shipping (ABS) 2009 approval for specialist subsea mooring connectors.
Ball and taper subsea mooring connectors (SMCs) offer a two-part mooring. A connector receptacle is preinstalled, attached by ground chain to a mooring pile. When the spar arrives on-station the ball and taper mooring connector is attached to the mooring line and lowered into the receptacle to complete the mooring line connection.
The Heidelberg spar will have a capacity of more than 80,000 b/d and 2.3 MMcu m/d.
