Seabox AS Acquired by NOV

National Oilwell Varco (NOV) has acquired 97% of the shares in Seabox for an undisclosed amount from a group of shareholders led by HitecVision.

Seabox is a Norwegian subsea technology company founded around the patented SWIT technology (Subsea Water Intake & Treatment). The technology enables treatment of raw seawater on the seabed (as opposed to on a platform) for injection into oil & gas wells for pressure support and increased oil recovery.

The company was established in 2004, and has, through a series of Joint Industry Projects backed by the Norwegian Research Council and by potential end-users such as ExxonMobil, ConocoPhillips, Shell, Total, Statoil, GDF Suez and others, developed the technology to a level where it is now ready for commercialization. Seabox has 12 employees.

Helge Lunde, CEO of Seabox comments: “We are very excited to team up with NOV’s global organization, which will significantly increase our reach and chances of succeeding in commercializing our technology. We are both proud and happy for their recognition of our efforts and technical solutions, and their commitment to backing us through the coming growth phase. We are convinced that our growth will be faster and stronger together with NOV.”

Michael Hjorth, President of Flexibles and Subsea Production Systems, comments: “NOV has a strong history and presence in Norway, where some of our key technologies for drilling, turret mooring and deck cranes have been developed, and to a large degree also manufactured. When it comes to subsea, which is an area where NOV wants to develop and expand, Norway is pretty much the “Silicon Valley” of the industry, so it is natural for us to search for new technologies and ideas here. In Seabox we have found what we deem to be innovative yet robust technical solutions, which offer more cost effective solutions but more importantly will offer the oil & gas companies greater flexibility in optimizing their reservoir drainage and field profitability. This is a huge market, with some 250 million barrels of seawater injected daily world-wide, which is almost three times the daily oil production. We are excited to explore these market opportunities together with Seabox.”

Huisman to Deliver Well Intervention System for Helix’s Q7000

Huisman, a Dutch specialist in lifting, drilling and subsea solutions, has secured a new contract from Helix Energy Solutions Group, Inc. for the delivery of a Well Intervention System onboard Helix’s new build Semi submersible “Q7000”.

The system, which is based on Huisman’s proven Multi Purpose Tower (MPT) design, will be built by the Huisman production facility in China.

The fully integrated 800mt Well Intervention System will be capable of handling the Intervention stack, the high pressure riser and other components. The Huisman Multi Purpose Tower has the same functionality as a normal derrick but offers improved accessibility to the well center, which allows for new improved handling procedures that increase efficiency and safety. The superior accessibility to the well center and the small footprint of the MPT are ideally suited for well intervention and subsea installation services. Subsea equipment can be skidded into the well center from three sides, offering enhanced flexibility.

The active heave compensation hoist system of the MPT provides excellent means for safe landing of equipment at the seabed while the passive heave compensation system provides a safe and redundant means to supply top tension to the risers. A guide trolley, travelling the entire length of the tower, guides the subsea modules during lifting operations. The system also features multiple transfer hatches that can be used to move equipment into the well center, and a skiddable work floor covering the moonpool flush with main deck.

The skiddable work floor allows large subsea modules to be deployed, without the need for a raised work floor. When large objects need to pass the moonpool the work floor can be skidded aside. In closed position, the work floor is flush with the main deck, which significantly reduces HSE risks and improves equipment handling on deck.

In addition to the Well Intervention System Huisman will also supply a 150mt Knuckle Boom Crane and a 160mt Pedestal Mounted Crane. Previous orders from Helix, amongst others, the Multi Purpose Tower onboard the “Q4000”, “Well Enhancer” as well as the cranes for the “Q4000” and “Q5000”.

Q7000: Helix Orders Semi-Submersible Rig from Sembcorp Marine

Sembcorp Marine’s subsidiary Jurong Shipyard has secured a US$346 million contract to build a second semi-submersible well intervention rig for Helix Energy Solutions Group, Inc. (Helix), a market leader in subsea well intervention services.

Scheduled for delivery in mid-2016, the semi-submersible light well intervention rig will be built based on a design jointly developed by Sembcorp Marine Technology Pte Ltd (SMTP), a fully-owned Research & Development subsidiary of Sembcorp Marine, and Helix. Featuring the latest technology, the rig – named Q7000 by Helix – is an efficient purpose-designed platform with capabilities to perform a wide variety of tasks, including conventional and extended top hole drilling, subsea construction, decommissioning well intervention, coiled tubing operations and twin ROV deployment.

The Dynamic Positioning (DP) class 3 unit has the ability to operate in deepwater operations worldwide, including the North Sea and West of Africa.

William Gu, General Manager of Offshore Division said: “We are honoured that Helix has chosen to build their second semi-submersible well intervention rig with us. This repeat order is significant as it testifies as to their trust and confidence in our design and building capabilities in rigs with well intervention and subsea capabilities that are customised to meet this new growth segment of the market. We are committed to build on our partnership with Helix and to meet their stringent standards of quality, safety and reliability.”

Owen Kratz, Helix’s President and Chief Executive Officer, said: “We are pleased to work with our trusted partner Jurong Shipyard on this second unit of the semisubmersible well intervention rig, to be named Q7000.”

The above is not expected to have any material impact on the consolidated net tangible assets per share and earnings per share of Sembcorp Marine for the year ending December 31, 2013.
