GustoMSC presented the Magellan-class drillship, the next step in deep-water drillship design.
Named after Ferdinand Magellan who was the first sea explorer to circumnavigate the earth, GustoMSC developed the Magellan-class drillship in the explorer’s own tradition of endurance, perseverance and determination. The Magellan is outperforming the current generation fleet with respect to redundancy, autonomy, safety and load carrying capacity.
Advanced new drilling techniques and developments in drilling equipment, together with the growing interest in units that could drill in deeper water and have more operational flexibility and capability, prompted thinking about a new class of drilling vessel. “The design is the result of a specific focus on operators’ requirements. We also received feedback on our existing products and, of course, learn from the industry in general. After the Macondo incident in 2010, for example, there were many recommendations concerning operational procedures and rig design – with an emphasis on safety. We naturally wanted to incorporate that information into the new design,” says Sjoerd Hendriks, Design Manager of the Magellan project.
The Magellan is the largest drillship that GustoMSC has designed to date. The design backbone of the ship consists of the well-established and field-proven principles of its predecessors. The most important step forward is that the Magellan design is equipped for 20,000 psi well-control systems, including the associated increases in capacity, such as high hook loads and setback capacities. Magellan’s ability to accommodate higher pressure, high variable loads, mud volumes and setback capacities and incorporate any type of advanced drilling techniques – such as managed pressure drilling and dual gradient systems, means it is equipped to drill well beyond the current market limit of 12,000 feet.

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”.

Fincantieri, one of the largest shipbuilding groups in the world, is showing its strong commitment in the offshore market, not only through its new subsidiary VARD (previously known as STX OSV), but also by providing the market with the next generation of drillship: the “OVERDRILL design” which will put the drilling contractors in condition to drill to an overall max depth of 50.000ft.
The OVERDRILL design, which has been developed by Fincantieri in cooperation with Aker Solutions, incorporates perfectly Fincantieri Offshore’s mission to offer vessels born and designed around the drilling system, maximizing its integration with the hull. Aker Solutions has supported the development of the new Fincantieri Offshore’s design based on its experience as a supplier of high quality drilling equipment and services.
Compared to other ships of this category, the ones of OVERDRILL design will also feature an increased variable deck load capacity despite reduced overall dimensions. This represent an opportunity for the drilling contractors to evolve their current fleet with a new class of vessels, featuring a higher level of performance and efficiency at the same time, which can be further adapted to their specific requirements and operational attitudes.
The number of offshore wells currently account for about 15% of the global total. Although offshore drilling activities have been successfully going on for several decades, the current phase, with its move into ultra-deep waters, might be the start of a new era.
Commenting on the new design Mr. Giuseppe Coronella, EVP of Fincantieri Offshore, said: “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”.
Mr. Thor Arne Håverstad, Head of drilling technologies at Aker Solutions, said: “Fincantieri Offshore’s expertise in vessel design combined with Aker Solutions’ knowledge of drilling technologies created a very powerful partnership, which made it possible to create the OVERDRILL design.”
The drilling package is designed to meet new requirement related to water depth and drilling length with upgraded capacities, such as increased well pressure (20k) and hook load (1500st).
OVERDRILL design will be presented during the Houston OTC of May 6-10, 2013.
Noble Corporation today announced that the Company has entered into two three-year term drilling contracts with Plains Exploration & Production Company for the Noble Sam Croft and the Noble Tom Madden, two of Noble’s new ultra-deepwater drillships currently under construction at the Hyundai Heavy Industries Co.

Seadrill is an outstanding company and we are looking forward to the business relationship.”
Drilling contractor Pacific Drilling S.A. has announced that Total S.A. has elected to exercise a one-year option to extend the firm contract term for the Pacific Scirocco to January 2015.
The contract provides for a further option, to be exercised at the client’s discretion by April 7, 2014, which could result in two additional years of contract term at a higher dayrate.
The additional one year term increases the drillship’s backlog by approximately $180 million, bringing the company’s total contract backlog as of April 9, 2013, to approximately $3.4 billion. The additional extension for two years would add a further $364 million backlog if exercised.
The Pacific Scirocco is capable of operating in water depths of up to 12,000 feet and drilling wells 40,000 feet deep.
With the heightened expectations of stakeholders in the aftermath of the Deepwater Horizon incident, Hyundai Heavy Industries (HHI) has listened to its drilling operator clients and designed a new generation of drillship. The new 80k class, heavy duty, wide beam drillship design, HD12000, can drill up to depths of 12,000 feet.
It has greater versatility, strength and more available deck space than its predecessors and has been developed drawing on previous experience of drillships. The HD12000 has an increased beam, which allows for larger and more variable load capacity (up to 24,000 metric tonnes) and reserve buoyancy for heavy duty – with compartment arrangement improvements – as well as being able to accommodate a cylinder rig concept that could be used for bigger derrick load requirements.
The JDP put the wide beam drillship design through design review, ship motion analysis, fatigue and FE analysis. Throughout, and on a global basis, Lloyd’s Register experts in hull structures, marine, mechanical, electrical and drilling systems worked in co-operation with HHI’s lead engineers to review and give feedback on the design development.
At the closing meeting at HHI’s Ulsan shipyard, Gyung-Jin Ha, Executive Vice President, Hyundai Heavy Industries, commented: “HHI and Lloyd’s Register have strong advantages in their own specialised fields, and it is therefore desirable to share experiences with each other and have cooperation between the two companies. HHI will never stop innovating to meet new market demands.”
Lloyd’s Register Drilling Integrity Services specialists in Moduspec were able to provide 25 years of valuable ‘people, systems and equipment’ insight and perspective regarding the drilling systems arrangements, when considering the operational integrity of the proposed design. At 223 metres long, 40 metres wide and 18.5 metres deep, the HD12000 drillship can probe a depth of 40,000 feet below the rotary table and is designed to accommodate the increasing complexity, pressures and sizes of drilling equipment and their handling needs. In addition, the arrangement of mud pumps and riser hold storage inside the hull envelope provides for a large free deck area for tube storage and other equipment, as well as greater flexibility and versatility of operations.
It has fully dynamic, positioning-compliant, station-keeping capabilities, with sufficient power to allow it to maintain position in emergency situations. Efficient The HD12000’s innovative hull form design is based on HHI’s longstanding and accumulated technology on merchant vessels. It enables a high transit speed of 11.5 knots (reduced form resistance with integrated thruster pod to hull) with a reported 40% less fuel consumption, enhanced sea-keeping performance (reduced roll angle by 20%), reduced interaction and thruster efficiency improvement and enhanced DP capability (reportedly 20% less fuel consumption).
A patented thruster canister design allows for in-site inspection and maintenance of the thruster without the need for docking, with reduced non-productive time.
Alan Williams, Lloyd’s Register’s Korea Marine Operations Manager, said: “Lloyd’s Register has been able to clearly demonstrate to a significant customer for drillship construction how it can support them, drawing upon the pool of expertise from across the organisation for that segment. Korea represents the technological coalface for drillship construction, gaining momentum for innovation, and we will continue to play our part. Lloyd’s Register is positioned to fully support the drilling operators and building yards through integrated marine and drilling system specialist teams, working closely with these clients to develop and offer solutions.”
The latest revision of LR’s rules for Mobile Offshore Units utilises the specialist drilling integrity capabilities of Moduspec and WEST, and will incorporate new classification notations for mobile offshore drilling units. These will be released in February.
