DUBAI, UAE – Drydocks World has completed Eagle Texas, a tanker also designed to serve as a modular capture vessel (MCV) in the Gulf of Mexico.
In this alternate role it would provide containment services following a deepwater well control incident in the region.
Drydocks World converted the vessel from an AFRA max tanker for Singapore-based shipping group AET. The latter has a 20-year agreement to provide two MCVs to Marine Well Containment Co. (MWCC), the consortium comprising Anadarko, Apache, BHP Billiton, BP, Chevron, ConocoPhillips, ExxonMobil, Hess, Shell, and Statoil.
In total Drydocks World fabricated 2,530 metric tons (2,789 tons) of steel for the construction program with 19.68 km (12.3 mi) of pipes and 292 km (181 mi) of electrical cables.
The MCV will have 700,000 bbl of liquid storage capacity, and can process, store, and offload liquids to shuttle tankers. Modular, adaptable process equipment on the vessel will connect to the riser assembly that directs flow from the subsea components.
The process equipment will then separate the liquids from gas, safely store the liquids and flare the gas. Thereafter the liquids will be offloaded to shuttle tankers for transport to shore.
In Dubai, the work scope of the shipyard included installing 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 future installation of topsides processing modules, a turret, flare tower, communications equipment, and control facilities.
In addition, 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 living quarters were also upgraded to accommodate more than 65 persons. The program included mechanical completion, pre-commissioning, commissioning, testing and sea trials of the converted vessel were also carried out.
