Delmar Installs 'World's Heaviest' Tree Systems in the Gulf of Mexico

Delmar Systems continues to meet the challenges of ultra-deepwater subsea projects by using the Heave Compensated Landing System (HCLS) to successfully install three of the "heaviest tree systems in the world."

These 240,000-lb systems were installed at BP's Viosca Knoll 915 (King South) and Mississippi Canyon 129(Dorado) locations in October 2008 in water depths of 5600' at King South and 3500' at Dorado using the Edison Chouest AHV.

The HCLS provides for a safe, efficient, and cost-effective method for subsea component installation. Delmar Systems, Inc. has used this patented HCLS technology for installing a variety of different components ranging from construction to field maintenance activities. This installation method has now been used for over 150 subsea tree installation as well as a number of equipment recovery campaigns for equipment refurbishment and reuse. It has also been used in the Gulf of Mexico, Angola, and Brazil. Delmar is a licensed user of this patented technology owned by Shell Oil Company (US Patent #5,190,107).

"The use of the HCLS minimizes rig critical path installation activities, increases utilization of existing long-term chartered installation vessels, and accelerates development timelines," said James Soliah, Delmar's subsea manager. "The HCLS provides for a safe, efficient, and cost-effective method for subsea component installation."
