NEUILLY-SUR-SEINE, France – MatthewsDaniel, part of the Bureau Veritas group, has completed its marine warranty services for Anadarko on the installation of the Heidelberg spar in the Gulf of Mexico. The installation was done using the semisubmersible crane vessel Thialf.
MatthewsDaniel provided project engineering review and attendance monitoring for all critical operations including the lift and set of the spar production topsides, living quarters module, stair towers, platform crane, flare boom, and cellar deck extension.
Located in the Green Canyon area of the Gulf of Mexico, the Heidelberg joint-venture is led by Anadarko Petroleum Corp. and features a truss-spar design. The spar dimensions are 33.5 m (109 ft) diameter, 184 m (603 ft) length, and gross weight of nearly 20,000 metric tons (22,046 tons) moored by nine combination chain/polyester mooring legs in 1,600 m (5,249 ft) water depth.
Installation of the topsides involved transportation to its location 390 mi (628 km) offshore from Corpus Christi, Texas, and a lift of 9,255 metric tons (10,201 tons) to set the main topsides in place.
