Aquatic, the flex-lay and retrieval brand in Acteon’s Energy Services division, completed installation and project support on the Crown and Anchor project. Aquatic was subcontracted by TechnipFMC in support of the installation of the LLOG Exploration Crown and Anchor project, which involved the installation of umbilicals, risers, and flowlines. The field is in the Viosca Knoll Block 959 of the Gulf of Mexico in 3,300-ft. water.
Aquatic provided equipment and personnel for the project and deployment of its 500 Te Powered Reel Drive System supporting the installation of 3 umbilicals (dynamic, gas lift and static), from 2 x 9.2m reels.
Installation and mobilisation activities on the TechnipFMC Deep Blue vessel were supported by Aquatic’s locally based equipment from Morgan City, Louisiana and operations personnel from both the US and UK.
Over 10,000 ft. (more than 3 km) of dynamic and gas lift umbilicals were installed from a single 9.2m reel. An additional, 29,000 ft. (more than 8 km) of static umbilical was installed from a second 9.2m reel.
The Aquatic equipment was configured to complement the TechnipFMC vessel equipment during installation and involved front-end collaboration between Aquatic’s and TechnipFMC’s engineering and operational teams. These equipment refinements included:
The client was extremely satisfied with the high level of attention and coordination that went into ensuring the Powered Reel Drive System (PRD) operated efficiently and safely during the vessel lay operations ensuring successful fail-safe operations, and completion of the project.
