Контекст:

Перевожу резюме менеджера по проекту. В одно время этот чел работал в качестве Senior Marine Operations Manager и в его обязанности входило:
1. Project manager of XXX project. This endeavor entailed the design, installation, of the back down mooring systems.
2. Completed re-design and installation of the suction skid for the ROV's.

Subsea 7's Mooring Suction Anchor Installation
Brazil's Barracuda - Caratinga field is situated in the Campos Basin in water depths ranging from 2,493 to 3,608 feet (760 to 1,100m). A total of 52 subsea wells will produce from reserves of 1.229 million barrels of oil and 14.7 billion cubic meters of gas.

The main field development contract was awarded to Kellogg Brown & Root, who sub-contracted the subsea installation scope of work to Subsea 7. The project's work scope comprised the installation of all subsea hardware, including suction anchors for the floating, production, storage, and offloading (FPSO) vessel's mooring and riser anchoring.

The installation raised various engineering challenges related to the 5m-diameter, 90-ton mooring suction anchors. Subsea 7 answered the challenges by building an ROV-based suction skid system, orienting the pile heading, and overcoming the potential resonance in the lift lines.

Suction anchors are cylindrical steel tubes, open at the lower end and closed at the top. Installation involves lowering the anchor to the seabed at the correct location, where it sinks into the seabed a certain distance (self-penetration).

The water inside the anchor is then pumped out by an ROV fitted with a special pumping skid, causing the anchor to be sucked down into the seabed to the required depth. Once in position, lines are attached to the anchors used to moor the FPSO or the flowline risers.

Each anchor has an internal volume of 325 cubic meters that must be displaced during installation. An efficient suction skid is required to drive it to the correct depth in an acceptable time.

Subsea 7 built two suction skids that were fitted underneath and powered by a work class ROV. Careful interfacing of the skids allowed unhindered operations of other ROV functions.
