New drilling semi-submersibles
has launched a new drilling semi- submersible series: the Ocean-HE. Based on extensive experience in harsh environments and existing Ocean designs, these units aim to add value to the market in terms of safety, workability and efficiency. The Ocean-HE and Ocean1600-HE
D
form the basis for the mid-water and deepwater harsh environment regions of operations. The semi-submersible hull shape is especially designed for low motion characteristics and optimum station keeping capabilities. The Ocean1600-HE is the top of the range and the largest drilling semi design by GustoMSC to date. With a maximum displacement of approximately 70,000 tons, a large derrick, DP3 and a 16 point mooring system for station keeping, combined
riven by the increasing requirements for harsh environments, GustoMSC
with a large deck area and large variable deck load, it aims at the high-spec deepwater spectrum. It is designed to cope with the North Atlantic environmental conditions. With the Ocean850-HE a cost-efficient midwater harsh environment design is provided. In the current market CAPEX needs to be controlled as well as the OPEX, to enable operators to work profitably at a reasonable day rate. It resulted in a moored-only harsh environment semi-submersible of around 50,000 tons displacement with
a water depth rating of 1,000m and a sixth generation efficient single derrick combined with horizontal riser storage. GustoMSC has been involved in
the design and engineering of semi- submersibles since the 1970s. In the mid-1980s, Keppel Fels-DTG and GustoMSC teamed up to develop the DSS series of drilling semisubmersibles, including the Maersk D-rigs, the Gold Star and the Floatel DSS20-NS designs. This successful development is still continuing. GustoMSC’s proprietary Ocean
series, started in 2008, has also become a success story with five units built and introduced within weight, budget and time. With the introduction of the Ocean-HE series GustoMSC is able to provide full coverage of the harsh environment drilling spectrum. l

Partnership sets out to challenge traditional maintenance The agreement covers Maersk
M
aersk Drilling and National Oilwell Varco have entered into a five-year partnership to improve
maintenance predictability for drilling equipment. The shared vision behind the partnership is to implement a new maintenance mindset that will increase value for customers by minimising operational downtime, while lowering maintenance cost levels.
Drilling’s three deepwater D-class semi-submersibles as well as the four ultra-deepwater V-class drillships. Until now, major overhaul of drilling equipment has been carried out with five-year intervals as part of the special periodic surveys (SPS) at quayside. Through the partnership, Maersk Drilling will switch to a condition-based maintenance strategy, where overhaul and repairs will, to the extent possible, be carried out as rolling maintenance while the unit is operating. “This is a new way of looking at
maintenance, and our ultimate goal is to eliminate the need for quayside SPS yard stays every five years, while still ensuring the highest level of safety and operational efficiency possible. We wish to collaborate with industry leaders to challenge traditional ways of thinking and continue to enhance

the way we operate,” explains Frederik Smidth, CTO. To continuously improve the
entire process from daily scheduled maintenance to major overhauls, it is crucial to include knowledge and experiences from both the equipment designer and operator. “By partnering up with National Oilwell Varco, we aim to achieve a higher level of maintenance predictability, hereby reducing the cash-flow impact from maintenance activities – ultimately resulting in less downtime for our customers. Collecting, analysing and sharing data as well as detailed knowledge about the equipment will be key in succeeding, which is why we believe a long-term partnership is a must,” Smidth continues. l
