Heerema Marine Contractors contracted C & C Technologies, Inc. and alliance partner Century Subsea, for the Vastar Resources, Inc., Horn Mountain SPAR Project. The SPAR was successfully moored in approximately 5400 feet of water in the Mississippi Canyon Block 126 and 127 in the Gulf of Mexico.

Heerema hired C & C for surface and subsurface positioning on the CV Balder and AHT President Hubert while installing nine suction piles and the SPAR hull. Surface positioning was completed with the aid of C-Nav, C & C’s new worldwide DGPS service. A Long/Ultra Short Baseline network was used to perform the subsurface positioning.
