InterMoor Heave Compensation from Vessel of Opportunity
In the Gulf of Mexico, InterMoor provided heave compensation services for the Cross Group’s installation of a 29t workover riser package (WRP) in approx 140 m water depth. On board Cal Dive’s Uncle John DP saturation diving vessel, 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… 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 m and can accommodate loads up to 50 t.
