CONTAINMENT CAPABILITY

EXPANDED CONTAINMENT SYSTEM

About the System

The expanded containment system is being built for use in deepwater depths up to 10,000 feet and has the capacity to contain up to 100,000 barrels of liquid per day (and handle up to 200 million standard cubic feet of gas per day). The expanded containment system will include a 15k psi subsea containment assembly, dedicated capture vessels and a dispersant injection system.

Significant progress continues toward delivering the expanded containment system, which began delivery in 2013 and is expected to be available in 2014. Fabrication is underway on all key components. The capability of the interim containment system will continue to build as components of the expanded system are completed and delivered.

In April 2013, MWCC announced that Theodore, Alabama, near Mobile, had been selected as the shore base location to house its subsea umbilicals, risers and flowlines (SURF) equipment. MWCC will utilize the facilities and services of Technip USA and Core Industries to store, maintain and test the equipment, which is an integral part of its ECS. In July 2013, MWCC then announced that Ingleside, Texas had been selected as the shore base location to house equipment to outfit the company's modular capture vessels (MCVs) in the event of a deployment. The equipment, which includes modular processing facilities for the MCVs and the centerpiece of the containment systems, the capping stacks, will be stored, maintained and tested at Kiewit Offshore Services' Ingleside facility near Corpus Christi.

Surface Components

The expanded containment system design includes use of capture vessels (modified Aframax tankers) with up to 700,000 barrels of liquid storage capacity, and can process, store and offload the liquids to shuttle tankers, which can then safely take the liquids to shore for further processing.

Modular, adaptable process equipment will be installed on the capture vessels and 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 handle the gas. Then the liquids will be offloaded to shuttle tankers which will transport the liquids to shore.

During hurricanes, capture vessels will disconnect and move away from the storm for the safety of the operating personnel. Once the storm passes, the vessels will return and be reconnected to the subsea containment components.

Subsea Components

A newly-fabricated subsea containment assembly (SCA) will create a connection and seal to prevent fluids from escaping into the ocean. The assembly will be equipped with a suite of adapters and connectors to interact with various interface points, including a variety of well designs and equipment used by oil and gas operators in the U.S. Gulf of Mexico.

If the well will allow, this assembly can shut in the well and stop the flow, without additional system equipment. If there are well conditions that require that the flow continue, the SCA will attach to risers and other containment equipment to direct the flow of fluids to the capture vessels for storage.

The fluids, captured by the SCA, will flow through flexible pipes to riser assemblies, configured to connect to the capture vessels at the ocean surface. An additional component will be available to inject dispersant into the subsea system during a hurricane when surface vessels must disconnect.

Vicinay Cadenas was recently selected by Technip USA to design and fabricate tether chains that will be utilized to secure the free-standing riser assemblies, should they be deployed. The free-standing riser assembly would be utilized when the modular capture vessels are deployed at water depths greater than 2,000 feet.

Using specialized equipment as pictured below, chains are efficiently rotated through welding, cleaning and cooling steps.

Chain links are being slowly raised into a hot furnace to receive heat treatment. Following heat treatment, each link will be bathed in water to cool the steel, followed by testing for strength.

The EAGLE TEXAS has entered the drydock in Dubai at Drydocks World Dubai (DWD) to continue the construction phase of the ship conversion. While in the drydock, this phase of the ship conversion of the EAGLE TEXAS will include a variety of steel work to the forward and aft thruster rooms, installation of bridge wing extensions, under deck strengthening to support the new topside process modules and the turret outrigger, installation of a larger controllable pitch propeller, extensive rudder modifications, a new jib crane, and accommodation upgrades.
