Galliano, LA: Edison Chouest to build 40 new supply vessels

BY: Jennifer Larino, Managing Editor

Edison Chouest Offshore said today it will build more than 40 new vessels to meet growing demand for offshore oil and gas support in the Gulf of Mexico, the Arctic and Brazil.

The new vessels continue an aggressive build campaign the Galliano-based company launched in 2011. The privately held company, which has vessels under construction at shipyards through the U.S. and in Brazil and Poland, did not disclose the cost of the newest round of builds.

Most of the construction work will be spread among Chouest’s four U.S.-affiliate shipyards — North American Shipbuilding in Larose, LaShip in Houma, Gulf Ship in Gulfport, Miss., and Tampa Ship in Tampa, Fla. — as well as its Brazilian shipyard, Navship.

The largest portion of the new build program will be the construction of 17 diesel-electric platform supply vessels. Chouest intends to market the new vessels, which feature a new hull form designed to carry more weight while lowering hydrodynamic resistance, as a more fuel-efficient option to oil and gas operators in the Gulf of Mexico.

Chouest’s plans also include two new ice class vessels designed for service work in the Arctic and four new subsea construction vessels slated for service in the Gulf of Mexico. The company’s fleet of icebreaking vessels, which will total six when the new builds are delivered, has supported Royal Dutch Shell’s drilling activity in Alaska.

Chouest also provided an update about its affiliated port facilities at Port Fourchon.  The C-Port 3 facility currently under construction will open in March and feature six covered slips to transfer cargo and provide support for deepwater support vessels. Design has begun on an additional section, C-Port 4, which could have as many as nine covered slips.

The company is also planning to expand its C-Terminal worksite at Fourchon to include outside storage areas, warehouses, cement and barite plants, and fuel, water, mud and drilling fluid sales stations. Chouest purchased the facility earlier this year.

Chouest, founded as Edison Chouest Boat Rental in 1960, operates a fleet of nearly 250 offshore service and support vessels worldwide.

VIDEO: Ulstein, NOV Present Next Generation Offshore Vessel

In the following video, National Oilwell Varco (NOV) and ULSTEIN present what they describe as the “next generation of modern offshore vessels.”

According to the caption of the video published on Ulstein’s YouTube channel “this is the standard for future offshore construction.”

The vessel platform used is the ULSTEIN designed Deepwater Enabler.

The 160.0 m long Deepwater enabler is a Multi-purpose Offshore construction vessel of a highly flexible design that can, according to Ulstein, be customized to meet client’s specifications and requirements.

The construction vessel is designed for various offshore operations. With a simplistic customization process it can be used to install and maintain offshore wind turbines, as well as for flex-lay, well intervention and slim hole drilling operations for the offshore oil and gas industry.

If February this year, Toisa placed an order for a construction vessel of the Deepwater Enabler design. The vessel will be built by South Korea’s Hyundai Heavy Industries.

VIDEO: ‘Overdrill’ Drillship Design by Fincantieri and Aker Solutions

Fincantieri, one of the world’s largest shipbuilders, has launched a video showing its drillship design: The Overdrill.

The vessel is the next generation drillship which will enable the drilling contractors to drill to a maximum depth of 50.000 feet.

The design has been developed by joint effort of Fincantieri and Aker Solutions. The OVERDRILL design was first introduced to the public last month during the Offshore Technology Conference in Houston, USA.

During the event, Giuseppe Coronella, EVP of Fincantieri Offshore, stated: “The offshore drilling market is driven, on the one hand, by demand for traditional standard systems and, on the other, by ultra-deepwater exploration demanding innovative solutions. With support from Aker Solutions, Fincantieri has produced a rig design that provides solutions to both these needs”.

Ulstein Presents Benefits of Its SX121 Design

Advancement in technology is permitting the offshore oil and gas industry to move into progressively deeper and colder waters in remote locations. ULSTEIN supports this development by providing products and solutions that contribute to safer, smarter and greener operations.

A case in point is the versatile and flexible OCV/subsea vessel design SX121, which ULSTEIN is currently building customized versions of for GC Rieber Shipping and Island Offshore. The design can be tailored for a multitude of offshore construction and subsea operations in deep and ultra-deep waters both below and above the Arctic Circle.

Deepwater and ultra-deepwater projects occur outside of the continental shelf at water depths between 400 and 1,500 metres and depths greater than 1,500 metres respectively. Deep waters mean remote locations, harsh weather conditions and sensitive ecosystems. This type of environment requires vessels that are reliable and safe, cost-efficient and environmentally sound.

“We aim to develop ships that can operate reliably, safely and efficiently in harsh conditions with as small an environmental footprint as possible. The robust configuration, system integration and X-BOW® hull line of the SX121 ensure safety and comfort for the crew, an increased operational window and significantly reduced environmental impact,” says sales manager in Ulstein Design & Solutions, Lars Ståle Skoge.

Currently, there are four sailing SX121 vessels designed and built by ULSTEIN. The vessels, which operate in different segments such as offshore construction, riserless well intervention and inspection/maintenance/repair, have received very good feedback.

Gordon L. Wilkinson in Veolia ES said the following about ‘Viking Poseidon’’s work in the Gulf of Mexico: “She is the Queen of the Gulf.”

At the end of 2012 shipowner Island Offshore, together with their American partner Edison Chouest Offshore, ordered another SX121 vessel from ULSTEIN currently under construction at Ulstein Verft. “We’ve received very good feedback on our two operating vessels of this design, ‘Island Constructor’ and ‘Island Intervention’,” says Technical Manager in Island Offshore, Trond Hauge. “I’m confident that this type of vessel is a safe and comfortable platform for the performance of advanced work in the years to come.”

Optimized for heavier installations

“The SX121 is a compact vessel that can perform deepwater and ultra-deepwater operations for which currently larger vessels are frequently used, thus providing the customer with a more cost-efficient solution,” says Håvard Stave, Sales Manager in Ulstein Verft.

“The typical SX121 vessel operates at depths down to 3,000 metres, which comprises most current oil & gas activities. The need to deploy heavier equipment in deep waters such as offshore Brazil and Africa and in the Gulf of Mexico, has spurred market interest in OCV vessels with a 400-tonne crane, which we’ve now incorporated in the SX121 design.”

ULSTEIN has drawn on experiences from its latest SX121 projects, and optimized the utilization of the hull with regards to work from deck as well as crane construction work, resulting in an even more versatile OCV/subsea vessel.

The robust platform is optimized for efficient operations in deep waters with a crane capacity of up to 400 tonnes and a substantial remaining deck loading capacity, and it can be configured for a variety of mission equipment. There is a large deck area of 1,750 m2, and the area around the main moon pool is reinforced in order to sustain a VLS or module handling system. The ROV installation is designed and chosen for operations in significant wave heights of 4.5 metres or more. Two heavy-duty work ROVs are situated in the enclosed hangar, one to be deployed from the starboard side, the other through a dedicated moon pool.

Extended redundancy

A reliable vessel is key for cost-efficiency, as down-time and aborting on-going operations are costly affairs, particularly when operating far from shore.

The SX121 vessel meets the highest standard for position keeping, DYNPOS-AUTRO, with redundancy on all major components. Featuring the ‘Operation+’ concept, an increase in redundancy in AUTR operations if a single major failure occurs, the vessel will still maintain system redundancy throughout the most critical areas. The typical configuration is diesel electric propulsion powered by six identical medium speed main generator sets. The switchboard system, propellers and diesel motors can be configured in groups of two, three or four. If a major failure occurs, the vessel will only lose one third of its power and propulsion. The combination of system architecture and power stations, three side thrusters and three main thrusters, ensures that the operation can be safely completed using two thirds of its capacity.

Smart and safe

In order to optimize capacities and performance of the vessel, the freeboard has been increased by one metre compared with the previously built vessels of this design. This increase also improves safety and ensures a dry work deck. In addition, the helideck has been moved further back in order to increase the weather window for helicopter landings.

The vessel’s X-BOW provides good motion characteristics for safe operations. It also reduces the vessel’s environmental footprint through lower fuel consumption and reduced emissions. With optimized resolution of the power generation plant, the vessel will have high fuel efficiency in all operational modes.

The vessel accommodates a crew of 130 and complies with all international requirements for comfort and safety.
