There is a marked preference for deepwater capability and a focus on drillships in recent orders. John Mueller reports.

New orders for offshore drilling rigs have been led by drillships, demand further underscored with the recent booking of six newbuild ultra-deepwater units. Floating production activity has also been highlighted by Golar LNG’s landmark move to have a Moss spherical tank LNG carrier converted into a floating LNG vessel.

Golar LNG reached agreement with Keppel Shipyard in Singapore for development of the company’s first floating LNG vessel, based on the conversion of an existing Moss LNG carrier of which Golar owns three potential candidates. Keppel will perform a front-end engineering and design (FEED) study, to be concluded mid-2013 when vessel conversion is expected to start. The completed FLNG vessel, estimated to cost around $600 million, will have a capacity of up to 2mtpa and utilize existing LNG storage of 125,000m3 on board the selected carrier.

Golar has already converted three Moss carriers into floating storage and regasification units of which Keppel delivered two.

Bumi Armada of Malaysia and Shapoorji Pallonji have taken delivery of FPSO vessel Armada Sterling, converted by Keppel Shipyard in Singapore from the 107,000dwt tanker Monte Umbe. The FPSO will be deployed for ONGC in the D1 field, 200km offshore Mumbai, for which the joint venture Forbes Bumi Armada Offshore has been awarded a seven-year charter worth $620 million.

Transocean has ordered four newbuild drillships from Daewoo Shipbuilding & Marine Engineering, prompted by the award of 10-year operations contracts for four ultra-deepwater drillships by Shell. The rigs are to be delivered from the DSME yard in Okpo, South Korea at six-month intervals from mid-2015 at an aggregate cost of $3 billion. The DSME-1200 design 780ft long by 138ft wide drillships will have the capability to drill in 12,000ft of water to 40,000ft and be equipped with 20,000psi BOPs and dual activity derricks.

Atwood Oceanics has entered into a turnkey contract with DSME to construct a third ultradeepwater DSME-1200 design drillship in South Korea, to be named the Atwood Admiral, delivery expected in 1Q 2015 at a cost $635 million. Rig design is identical to the previously ordered drillships Atwood Advantage and Atwood Achiever, all DP3 with dual derricks.

Seadrill has entered into a turnkey contract with Samsung Heavy Industries to build a ultra-deepwater drillship in South Korea valued at around $600 million, delivery in 4Q 2014.

national drilling companyNational Drilling Company of Abu Dhabi has taken delivery of two of its jackup drilling rigs, upgraded by Drydocks World in Dubai, UAE: Beynouna (above), which received major maintenance that included new spud cans, cranes overhaul, pipes renewal and improved accommodation; and Delma.

The unit will be capable of drilling in 12,000ft water depths and be equipped with a seven ram configuration of the BOP stack. Seadrill has also agreed to a fixed price option to build a further drillship at the yard, with delivery in 1Q 2015.

Rongsheng Offshore & Marine has secured an engineering, procurement and construction contract for a drilling assisted deepwater tender barge. The vessel will have a drilling depth of 20,000ft in water up to 6500ft deep.

D’Emerald is to purchase a newbuild jackup drilling rig under construction by China Petroleum Liaohe Equipment at its yard in China. The CPLEC CP-300 design rig will be capable of drilling to 30,000ft in 300ft water depths, delivery expected by 2Q 2013.

Teniz Burgylau has awarded Saipem, through its jointly controlled company Ersai Caspian Contractor in consortium with Keppel Kazakhstan, a contract for the fabrication, outfitting and commissioning of a KFels B Class jackup drilling rig. Designed for the Caspian Sea, the rig will be able to drill to 20,000ft in water up to 260ft deep. Final assembly and commissioning will be undertaken at Ersai Kuryk yard, the first jackup built in Kazakhstan with delivery in 1Q 2015.
