HOUSTON -- InterMoor has anchored a mobile offshore drilling unit (MODU) and preset anchors for a tender assist drilling (TAD) vessel for Cabinda Gulf Oil Co. (CABGOC) offshore Angola.
InterMoor provided design, engineering, procurement, and installation services for the permanent preset moorings at the Tombua Landana location and the Tombua South drill center. The company also handled the fabrication of a 60-ft (18-m) suction follower and various installation aids that were required for the installation of suction-embedded plate anchors (SEPLA) at Tombua Landana.
Eight mooring anchors were installed at both sites. At Tombua Landana, installation of the eight SEPLA anchors at a water depth of 1,250 ft (381 m) began on Oct. 28 and was completed by Nov. 5. On average, it took just more than a day per anchor to complete the installation, the company says.
