November 3 - London, UK headquartered MatthewsDaniel has completed marine warranty services on behalf of Anadarko Petroleum Corporation for the installation of the Heidelberg spar in the Gulf of Mexico.
MatthewsDaniel was on hand to provide project engineering review and attendance monitoring for all critical operations including the lift and set of the spar production topside, living quarters module, stair towers, platform crane, flare boom, and cellar deck extension. The installation works were completed using the semi-submersible crane vessel Thialf.
Located in the Green Canyon area of the Gulf of Mexico, the Heidelberg joint venture is led by Anadarko and features a truss-spar design. The spar measure 33.5 m in diameter, 184 m long and had a gross weight of nearly 20,000 tonnes, moored by nine combination chain/polyester mooring legs at a 1,600 m water depth.
The topsides, the largest of which weighed in at 9,255 tonnes, were transported to the offshore location 390 miles (623 km) from Corpus Christi, Texas.
Kevin Jarman, ceo at MatthewsDaniel, commented: "MatthewsDaniel enjoys a long-standing relationship with Anadarko, dating from our appointment in 1996 as marine warranty surveyor for the transport and installation of the world's first production spar. This is the latest example of MatthewsDaniel providing valued marine expertise for transport and installation of their high-value assets."
