World’s first Modular Capture Vessel sails away from Drydocks World

BY MELANIE CRUTHIRDS, News Editor

DUBAI -- International service provider Drydocks World has announced that the world’s first Modular Capture Vessel (MCV), Eagle Texas, sailed away from its yard. The conversion of the AFRA max tanker was carried out by Drydocks World–Dubai, and was completed for Singapore-based AET, a global petroleum shipping company, and is the first of two similar projects. AET is under a 20-year agreement with Marine Well Containment Company (MWCC), a consortium comprised of Anadarko, Apache, BHP Billiton, BP, Chevron, ConocoPhillips, ExxonMobil, Hess, Shell and Statoil. The consortium is committed to safe deepwater drilling in the U.S. Gulf of Mexico. The MCVs will operate as normal tankers in the Gulf, and would be deployed for containment services in the event of a deepwater well control incident in the region.

The amount of steel used for the project was 2,530 t, with an additional 19.68 km of pipes and 292 km electrical cables also used. The MCV will have 700,000 bbl of liquid storage capacity, and can process, store and offload the liquids to shuttle tankers. Modular, adaptable process equipment installed on the MCV will connect to the riser assembly that directs the flow from the subsea components. The process equipment will separate the liquids from gas, safely store the liquids and flare the gas. Then, the liquids will be offloaded to shuttle tankers, which will transport the liquids to shore.

The shipyard’s scope of work included installing components, including: four retractable azimuth thrusters, one tunnel bow thruster, new machinery spaces, diesel generator sets and associated tanks, auxiliaries, switchboards and electrical distribution equipment. The main engine was modified for CPP operation, and a control system was added for dynamic positioning, power management and equipment monitoring. Structural support stools and foundations were added for the future installation of topsides processing modules, a turret, a flare tower, communications equipment, control facilities and other miscellaneous equipment. The ship’s systems were modified to provide services to topsides processing equipment, as well as hydraulic systems for the CPP, thrusters, cargo valve control and fire pumps.  A new main deck central pipe rack was fabricated and piping was installed to support topsides processing equipment. The ship‘s living quarters were also upgraded to accommodate more than 65 people.  Mechanical completion, pre-commissioning, commissioning, testing and sea trials of the converted vessel were also carried out.
