The cutting edge Seven Viking vessel, designed for operations in the harshest environments is being unveiled and named at a ceremony in Stavanger, Norway, by Subsea 7, Eidesvik Offshore and Ulstein today, 30 January 2013.
The next generation Inspection, Maintenance and Repair (IMR) vessel, the Seven Viking, is co-owned by Subsea 7 and Eidesvik and has been constructed in partnership with Ulstein.
The ICE-C class vessel with a crew capacity of 90 and a top speed of 17 knots, will work for Statoil on a five year contract. It has been custom-built according to the operator’s specifications to carry out tasks including inspection, maintenance and repair of subsea installations in addition to scale treatment and RFO work scopes (Ready For Operations).
The vessel Godmother is to be Christine Sagen Helgø, the Mayor of Stavanger.
Subsea 7 Vice President for Norway Stuart Fitzgerald said: “The collective effort, and strong cooperation, between Ulstein, Eidesvik and Subsea 7, has resulted in the Seven Viking. The Seven Viking represents another class leading asset in the Subsea 7 fleet and captures Subsea 7’s unparalleled experience with IMR operations in harsh environments. The design and build of this state of the art vessel would not have been possible without the expertise and dedication of many people within both Subsea 7 and our project partners, and we take pride in their achievement. We look forward to many years of safe and efficient operations with Seven Viking for our Customer, Statoil.”
Jan Fredrik Meling, CEO Eidesvik Offshore said, “We in Eidesvik are very satisfied with the close and constructive cooperation with Subsea 7. The relationship between our companies has developed over many years and has enabled us, together with Ulstein, to launch this outstanding vessel.”
Gunvor Ulstein, Ulstein Group CEO said, “Ulstein is proud to deliver a vessel of unmatched technical and operational capacity in its sector, and I am confident that the Seven Viking will meet Statoil’s expectations.”
The Seven Viking incorporates the X-BOW® hull line design to reduce motion in transit and gives increased stability in the potentially high waves that characterise the North Sea. Despite this enviable stability usually associated with size, this version of the Ulstein SX148 design has been crafted to be compact in stature – measuring only 106.5 metres long and 24.5 metres wide. The dimensions will allow the Seven Viking to manoeuvre with ease in confined spaces, such as between platforms, accessing difficult to reach areas.
Thanks to a clever configuration whereby hull space is maximised and equipment is integrated within a large hangar area, the Seven Viking and its crew have the ability to carry all necessary maintenance equipment on board, ensuring that operational downtime is kept to a minimum.
Safety, efficiency and environmental considerations have been the prime focus for the three partners when developing the Seven Viking, which carries the Clean Design notation.
A customised module handling system (MHS) has been integrated in the ship’s hangar for the safe launch and retrieval of subsea modules weighing up to 70 tons through the moon pool.
To facilitate cooperation and communication, all operational personnel are gathered in one area adjacent to the hangar, with panoramic windows in the control room giving a full overview of this key activity area. The Seven Viking has been developed to meet the highest working environment standards, and is classified as a comfort class COMF-V (3) vessel. Minimal noise levels in the hangar have been achieved by opting for electric winches for the ROVs, the MHS and other utility equipment.
Notable environmental initiatives include diesel electric propulsion, which reduces atmospheric emissions, and the electrical winches which nullify the risk of emissions of hydraulic oil.

Jun 19, 2012 – Statoil reported that the Valemon jacket was successfully delivered and installed on the field, which lies in the Norwegian sector of the North Sea. The 9,000-ton steel jacket was carried out as planned and the project remains on schedule. The jacket, which was built by Heerema Fabrication Group in Vlissingen in the Netherlands, was transported from the shipyard and out to the field by the crane barge Thialf. Development of Valemon involves a fixed platform with a steel jacket for the separation of gas, condensate and water. The rich gas will be transported via a new pipeline to the existing pipeline from Huldra to Heimdal for further processing. The condensate will be piped to the Kvitebj??rn platform for stabilization and further transport via the Troll oil pipeline to the Mongstad refinery. At peak production, Valemon is expected to deliver roughly 86,000 barrels of oil equivalent per day. The field is expected to come on stream in the fourth quarter of 2014 and has a life expectancy of 11 years.

Jun 15, 2012 – Statoil has submitted a plan for development and operation for the Svalin field to the Norwegian government and reported it expects to bring the field online in 2013. Recoverable reserves at the field are estimated at around 75 million barrels of oil equivalent, with two structures Svalin C and Svalin M containing similar quantities. The Svalin C and Svalin M discoveries will be developed through a ‘fast-track’ method that uses a standard solution involving processing by existing infrastructure. The Svalin development will be tied-back to the Grane platform. Svalin M will be produced by a well drilled from the Grane platform, while Svalin C will be a subsea development connected via a four-mile long flowline to the Grane platform. The hydrocarbons will utilize shared processing and export facilities. The gas compression facility at the Grane platform will be modified to handle gas from Svalin. Oil from the Svalin development will be transported, along with production from the Grane field, through the existing pipelines for storage and shipment from the oil terminal at Sture.

There are great things happening aboard the vessel “Havila Phoenix” nowadays. During the last two years there have been installations and tests of a whole new system likely to revolutionise the offshore light well intervention market.
The vessel, a Havyard 858 design, is designed and constructed by the ship technology group, Havyard Group AS, and owned by Havila Shipping, both located in Fosnavåg at the west coast of Norway. The offshore construction vessel was delivered from Havyard Ship Technology in Leirvik, Norway in 2009.
The vessel has over the last year-and-a-half been working on a contract for Fugro-Salt Subsea, part of the massive Fugro group, which is a Dutch-based corporation with more than 14.000 employees spread across 60 countries. Fugro-Salt Subsea cooperates with Expro in terms of developing the new “AX-S”-system aboard Havila`s advanced construction vessel.
So far the development of this new system has been running for seven years and cost NOK 1.2 billion in research and investments in ground-breaking new technology. The breakthrough appeared around a month ago when tests in the Norwegian Onarheim fjord proved very successful.
“AX-S” is a brand new system for well intervention involving remote-controlled subsea tools. The new system is, according to both the Havila management and the management of Fugro-Salt Subsea, a revolutionary system using solutions so far never utilised in subsea operations from a construction vessel. This involves employing extremely advanced remote-controlled subsea tools during well intervention that can handle up to eight different tools within the same operation, as well as using a light fibre rope instead of heavy steel wires. These are the main elements of the recent innovation. Should the system also win approval in a business sense, it could have a major impact on the offshore light well intervention market.
STABLE HAVYARD VESSEL
In the last year-and-a-half the 110 metre long vessel, a ship now docked in the port of Montrose between Dundee and Aberdeen, Scotland, has looked more like a research station than an offshore vessel. Havila Phoenix has been outfitted with a 35 metre tall tower and several modules on deck with a combined weight of over 500 tonnes. And there is no coincidence that the Scottish group has chosen a Havyard 858 design for this unique project.
- We needed a big, solid and modern vessel, and Havila Phoenix has lived up to all our expectations. If we fully succeed with this project we will likely be looking to acquire vessels of a similar design, but we will then need to be part of the planning straight from the start and get more of the system directly integrated below deck, says Operation Manager Darren Bown of AX-S.
The captain of Havila Phoenix, Leif Magne Lynge from Gursken, Norway, confirms that the vessel still remains impressively stable despite the enormous added weight.
- Yes, things have been working really well and the vessel also performs really well for its purpose. Facilities are also excellent, says Lynge who`s been captain aboard the vessel since the initial delivery. Captain and crew are definitely looking forward to heading out to the North Sea in order to start using this exciting new system.
UNIQUE REMOTE-CONTROLLED TOOLS
Michael Earlam of Fugro-Salt Subsea informs that there are several factors making the AX-S system a world sensation. In addition to the utilization of fibre ropes instead of wires for AX-S deployment, Earlam emphasizes the remote-controlled handling and deployment of the subsea packages with the ability to deploy 8 subsea tools is each time is unique.
- By using traditional well intervention equipment you can only perform one task at a time before the equipment needs to be raised to the surface in order to swap tools and then perform a subsequent operation. The equipment used in the AX-S system manages to handle eight various tools while on the seabed, without having to be raised to the surface to swap over any tools. This makes the operation much more effective and cost-efficient, Michael Earlam informs.
And after seven years of preparation the system is nearing its baptism of fire. In September, Havila Phoenix with 500 tonnes of “subsea factory” on deck will be heading out to work in the British sector of the North Sea.
- Yes, following the successful commissioning of the AX-S system on NUTEC’s “cold well” in Onharheimsfjord, south of Bergen, during April and May be performing operations in the North Sea, the Operations Manager for AX-S, Darren Bown of Expro, confirms.
