InterMoor Completes Heave-Compensation Job in U.S. GoM

InterMoor, an Acteon company, has successfully completed a contract with Cross Group, Inc. that included the provision of heave-compensation services for the installation of a Cross 7.0 workover riser package (WRP).

An InterMoor compensated anchor-handler subsea installation method (CASIM) unit played a key role in deploying and recovering the WRP.

“The CASIM system enabled us to provide effective heave compensation and to recover the delicate WRP on a vessel without an active heave-compensated crane or stern roller,” said InterMoor vice president of business development David Cobb. “That was the only way to achieve the WRP installation from this vessel. The success of this project underlines the value of the CASIM system as a cost- and time-effective solution, and explains why more and more subsea contractors and operators are choosing it to facilitate the installation of workover packages.”

Each standard CASIM unit has a maximum stroke of 3 meters and can accommodate loads up to 50 tons.

The heave compensation operation was in water depths of about 140 meters and used Cal Dive’s Uncle John DP saturation diving vessel to install the 29-ton WRP. The project took place at East Cameron well 378#3, offshore Louisiana, USA. The Cross Group is conducting a plugging and abandonment (P&A) program in the field for EPL Oil & Gas, Inc.

This project demonstrates how InterMoor can provide cost-effective solutions for the installation of subsea workover equipment using vessels of opportunity. Operators trust InterMoor to be part of their P&A campaigns and to help them meet BOEMRE NTL No. 2010-G05 requirements for timely decommissioning of idle infrastructure on active leases.
