Delmar Systems Inc. has set a new ultra-deepwater installation world record in the Gulf of Mexico. The company recently completed construction activities on the Coulomb development using the Heave Compensated Landing System (HCLS) to install 10,000-psi production equipment from an anchor handling vessel in 7,570 ft of water, establishing a new world record for installation.
The sixth addition to the Na Kika host facility consisted of two subsea wells tied back from the Coulomb field. The C-2 well is 100% Shell owned, and the C-3 well is 2/3 Shell owned and 1/3 Petrobras owned. The HCLS provides for a safe, efficient, and cost-effective method for subsea component installation, the company says.
The Na Kika semisubmersible production facility is moored in 6,350 ft of water, the deepest for any installation of its type in the world. In its entirety, the Na Kika development consists of five independent fields – Kepler, Ariel, Fourier, Herschel, and East Anstey – which Shell and BP have developed with the installation of a centrally located, permanently moored semisubmersible floating development and production facility. The Kepler, Ariel, and Herschel fields are primarily oil, while the Fourier and East Anstey fields are primarily gas. The sixth field, Coulomb, is primarily gas and is in 7,570 ft of water.
