Following sea trials during the past few weeks, Dockwise, a Dutch heavy lift and transportation specialist, now confirms the delivery of Dockwise Vanguard. The vessel has left the yard of Hyundai Heavy Industries (“HHI”) this morning and started its maiden trip.
Dockwise Vanguard will sail to the Samsung Heavy Industries (“SHI”) yard in Korea to pick up the giant hull of the Jack / St Malo semi-submersible floating production facility for transportation to the US Gulf of Mexico.
“We are pleased to see Dockwise Vanguard leave the yard following a delivery without a single LTI (Lost Time Incident), on schedule for its maiden trip for one of our key customers. As said before, we are confident that that the Vanguard will rapidly earn its place in the market and has the potential to create a new market of its own”, comments André Goedée, Dockwise’s CEO..

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.

Rowan Companies plc (“Rowan” or the “Company”) announced that it has exercised its option to build a fourth GustoMSC P10,000 design ultra-deepwater drillship with Hyundai Heavy Industries Co., Ltd. (“HHI”) with delivery scheduled in March 2015.
The cost for this rig, including commissioning, project management and spares, but excluding capitalized interest, is estimated to be approximately $620 million. This cost compares to peer companies’ previously announced 12,000 foot capable rigs equipped with 10,000 feet of riser. Rowan plans to equip its drillships with 2,000 feet of additional riser to enable operations in water depths up to 12,000 feet upon delivery. Each drillship will also be equipped with a second BOP for minimizing non-productive time. The Company will also incur operational training and personnel ramp-up costs in readying the drillships to commence well operations. Expected costs for the additional riser, BOP and training and ramp-up costs will be approximately $75 million. Total cost for the Company’s fourth drillship will be approximately six percent higher than the Company’s first three drillships primarily due to equipment price increases and projected labor cost increases. The agreement with HHI also includes an option for a similar fifth drillship exercisable in the fourth quarter of 2012, for delivery in the third quarter of 2015.
Matt Ralls, President and Chief Executive Officer, commented, “We are very pleased to add a fourth ultra-deepwater drillship to our fleet. The recent three-year contract obtained for our first drillship, the Rowan Renaissance, and strong customer enthusiasm for Rowan’s history of operational excellence, high-specification drillship design and experienced deepwater team, reaffirms our confidence in our expansion into the ultra-deepwater market.”
The Rowan Renaissance struck steel in July 2012 and is expected to be delivered in late 2013. The second and third drillships are expected to be delivered in the second and fourth quarters of 2014, respectively.
