    Default Hyundai unveils new drillship design

    with all the hoopla about the never ending Shell Alaska clown circus and that miserable excuse named Paul Watson, I missed this one earlier


    Hyundai Heavy Unveils the HD12000 Drillship, a Joint Development Project with Lloyd’s Register
    By Lloyd's Register On January 10, 2013

    A joint development project (JDP) between HHI and Lloyd’s Register meets market demand for a new generation of drillships

    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 specialized 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. Their input added strength to Lloyd’s Register’s holistic approach, in which a number of teams worked together on the JDP in various technology and support centres globally.

    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.

    Dont forgot these two new ones as well:

    Frigstad Offshore orders $1.3bn semisub pair







    11 January 2013 09:57 GMT


    Frigstad Offshore has ordered two newbuild ultra deep-water semi submersibles from CIMC Raffles at a cost of $1.3 billion.

    The Cyprus-registered, Singapore-based contractor has ordered the pair on turnkey contracts from the CIMC Raffles Yantai yard in China, with options for another four units.
    Frigstad Offshore chief executive Simen Skaare Eriksen said the order was a further step on the company’s road to becoming “a leading operator of ultra deepwater drilling units at the very top end of this highly attractive market segment”.
    Eriksen said he had full confidence in the yard’s capabilities, adding that “after the CIMC Group’s takeover of the Yantai Raffles yard, we have seen considerable improvements to infrastructure and execution skills at the yard”.
    The dynamically-positioned drilling units are of Frigstad Engineering’s Frigstad D90 design.
    The semi-submersibles are capable of operating in water depths up to 12,000 feet and drilling to a total depth of 50,000 feet, and will be outfitted with two blowout preventers as well as a dual activity drilling package.
    The pair are due for delivery by the end of the fourth quarter of 2015 and by the end of the second quarter of 2016 respectively.
    Frigstad Offshore is to manage the construction, marketing and operation of the rigs, which were ordered through its drilling subsidiary Frigstad Deepwater.
