Anadarko recently completed the successful upending of its massive 23,000-ton Heidelberg floating spar in 5300ft water depth, in Grand Canyon block 859, about 140mi off the coast of Louisiana.

The 80 MMscf/d capacity Heidelberg truss spar is the second of Anadarko’s “design one, build two” concept being deployed in the US Gulf of Mexico. Heidelberg’s twin spar, Lucius, began production in January of this year.

Heidelberg's topsides were constructed at the Kiewit yard in Ingelside. The hull was constructed by Technip in Pori, Finland. To reach Texas, the spar sailed 7300nm over 27 days from September to October 2014 on Dockwise's Mighty Servant I.

The Heidelberg spar has a topsides operating weight of 16,000-ton, and a hull weight of 23,000-ton. The spar's measures 605ft-long with a 110ft-diameter.

The Heidelberg development consists of six production wells, the standalone spar, two drill centers, dual looped 8in flowlines, and 16in oil and gas export lines. First oil from Heidelberg is expected by April 2016.

Anadarko operates Heidelberg with 31.5% interest. Its partners include Cobalt (9.375%), Eni (12.5%), ExxonMobil (9.375%), Freeport McMoRan (12.5%), Marubeni (12.75%), and Statoil (12%).
