Tug Fairmount Glacier has delivered rig La Muralla IV in Bay of Campeche, Mexico. The rig has been towed from Okpo, South Korea, via Sunda Strait and Cape of Good Hope.
La Muralla IV is a brand new semi-submersible drilling rig for ultra deep water operations, owned by Mexican Grupo R. The rig is constructed by Deawoo Shipbuilding & Marine Engineering in South Korea. La Muralla IV is designed to drill up to depths of 10.000 meters. The rig has a length of 118,6 meters and a width of 96,7 meters.
Fairmount Marine’s Fairmount Glacier hooked-up with the rig at the end of October last year offshore the port of Okpo, South Korea. The convoy sailed via Sunda Strait en Cape of Good Hope towards the Gulf of Mexico, where it arrived at the end of February after covering a distance of over 16,200 miles with an average speed of 6,6 knots.
During the voyage bunker stops were made in Singapore, Mauritius, Walvis Bay and Curacao. At Mauritius the Fairmount Glacier performed several runs between the port and the La Muralla IV to transfer cargo and crew.

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.

Pacific Drilling S.A. has reached an agreement with South Korea’s Samsung Heavy Industries to extend an option to construct an eighth ultra-deepwater drillship until January 18, 2013, on the same commercial terms, including delivery scheduled for the first quarter of 2015.
Pacific Drilling currently operates four recently delivered drillships under customer contract and has three drillships under construction at Samsung, two of which are under customer contract.
The Laguna Star, QGOG Constellation’s new ultra-deepwater drillship, arrived, Nov. 7, in Brazil. Samsung Heavy Industries shipyard, located in South Korea, built the Laguna Star as well as the Amaralina Star drillship, which is currently in operation by QGOG.
The unit will be operated by its subsidiary, Queiroz Galvão Óleo e Gás (QGOG), in water depths of up to 10,000 feet and well depths of up to 40,000 feet. It is equipped to operate in ultra-deepwater including the Brazilian pre-salt area.
The Laguna Star is the second drillship to be operated by QGOG, after Amaralina Star, which arrived in Brazil in August, 2012. The unit contributes to expanding and diversifying QGOG’s portfolio in ultra-deepwater drilling.
“The arrival of Laguna Star is another key milestone for the QGOG Constellation’s ultra-deepwater operations and, together with Amaralina Star, reinforces our operational track record,” said QGOG Constellation CEO Leduvy Gouvea.
These two drillships are chartered to Petrobras under six-year contracts, with options to renew for six additional years. Drilling services will be provided by QGOG.
