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.

Anadarko Petroleum Corporation today announced the Atum exploration well discovered another significant natural gas accumulation within the Offshore Area 1 of the Rovuma Basin.
The Atum discovery well encountered more than 300 net feet (92 meters) of natural gas pay in two high-quality Oligocene fan systems. Preliminary data indicates this latest discovery is connected to the partnership’s recent Golfinho discovery located approximately 10 miles (16.5 kilometers) to the northwest in the Offshore Area 1.
“The combined success at Atum and Golfinho and apparent connectivity of these Oligocene fan systems, indicate these discoveries represent our partnership’s second major natural gas complex offshore Mozambique,” said Sr. Vice President, Worldwide Exploration Bob Daniels. “We estimate this new complex, which is located entirely within the Offshore Area 1 block, holds 10 to 30-plus trillion cubic feet (Tcf) of incremental recoverable natural gas resources. We plan to immediately commence a four-well appraisal program of this complex, which has the potential to underpin a large LNG development.”
The Atum exploration well was drilled to a total depth of approximately 12,665 feet (3,860 meters), in water depths of approximately 3,285 feet (1,000 meters). Once operations are complete at Atum, the partnership plans to commence appraisal activities that are expected to be followed by a drillstem testing program in the Golfinho and Atum complex.
“With this latest discovery at Atum and a successful upcoming appraisal program, we believe the total estimated recoverable natural gas resource in Mozambique’s Offshore Area 1 is between 30 and 60 Tcf, and the current upside for total gas in place for the discovered reservoirs on the block is approaching 100 Tcf. We still have additional exploration opportunities that could expand the resource potential further,” said Anadarko President and CEO Al Walker. “A recoverable resource base of this scale supports our initial two-train development plans, as well as significant future expansions. Our current activity is focused on achieving reserve certification and a Final Investment Decision in 2013, as the partnership works toward expected first sales of LNG in 2018.”
Anadarko is the operator in the Offshore Area 1 with a 36.5-percent working interest. Co-owners include Mitsui E&P Mozambique Area 1, Limited (20 percent), BPRL Ventures Mozambique B.V. (10 percent), Videocon Mozambique Rovuma 1 Limited (10 percent) and Cove Energy Mozambique Rovuma Offshore, Ltd. (8.5 percent). Empresa Nacional de Hidrocarbonetos, ep’s 15-percent interest is carried through the exploration phase.
