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.

KBR to Design Bonaparte FLNG Vessel for GDF Suez

KBR has been selected by GDF SUEZ Bonaparte Pty. Ltd. (GDF SUEZ), operator of the Bonaparte LNG project, to execute floating liquefied natural gas (FLNG) production vessel design work for its project offshore Darwin, Australia.

This award is one of two contracts being let by GDF SUEZ as part of an initial concept definition design competition for the vessel. The award also pre-qualifies KBR as a contender for the EPC delivery phase of the project. The concept definition work is already underway in KBR’s London operations centre in Leatherhead, and is expected to last up to 12 months.

KBR has developed an extensive global FLNG engineering capability in recent years, and draws on its experienced resource pool with capabilities in FPSO and onshore LNG EPC delivery.

“KBR is delighted to be working with GDF SUEZ on this project. We look forward to working together in a new relationship which we hope will prove valuable for both companies as this project moves towards the EPC phase,” said Roy Oelking, Group President, Hydrocarbons.

This work follows KBR’s recent FLNG front-end projects in London, Houston and Perth. FLNG represents a new market for the industry and KBR’s engineering capability is already being utilized in several FLNG projects around the world.

Aker Solutions has been awarded a FEED (front-end engineering and design) contract from Statoil to design the world’s largest Spar platform for the Aasta Hansteen field development in the Norwegian Sea.

With a total hull length of 193 meters and a draught of 170 meters, the Aasta Hansteen (formerly named Luva) Spar platform will be the largest of its kind. A Spar platform is a cylinder shaped floating offshore installation. Aasta Hansteen will be the first Spar platform on the Norwegian continental shelf (NCS), and also the world’s first Spar platform with condensate storage capacity – a so called Belly-Spar.

The Belly-Spar concept is an exclusive Aker Solutions design. The ‘belly’ refers to the increased diameter on part of the circular shaped hull, where the condensate storage tanks are located. This gives the Aker Solutions’ Belly-Spar its characteristic shape.

Henning Østvig, head of Front-End & Technology in Aker Solutions says: “The Aasta Hansteen Spar will be the first production platform on the NCS with steel catenary risers. With a water depth of 1300 meters, this is probably the only riser technology that can meet the challenges on the Aasta Hansteen field”.

The steel catenary risers are made of self-supporting steel pipes in a bow shape between the platform and the seabed. The shape helps the risers compensate for the motions on the floating facility.

Innovation

“The Belly-Spar concept is a result of the innovative spirit and culture among our engineers, who have come up with the right solutions for the challenging conditions on the Aasta Hansteen field,” says Valborg Lundegaard, head of Engineering business area in Aker Solutions.

The mooring system for Aasta Hansteen Spar platform consists of a set of polyester lines. “There are currently no installations on the NCS with polyester mooring. Aasta Hansteen may be the first, and it will definitely be operating in the deepest water,” says Henning Østvig.

The FEED study will be completed in the third quarter of 2012. The contract value is undisclosed.

Aasta Hansteen

The field was discovered in 1997 and lies 300km offshore in the Vøring area. The licence partners are Statoil (75 per cent), ExxonMobil (15 per cent) and ConocoPhillips (10 per cent).

Aker Solutions’ contract party is Aker Engineering & Technology AS.
