M/V “Bourbon Orca”, an Anchor Handling Tug Supply Vessel of ULSTEIN AX104 design with ULSTEIN X-BOW, was elected SKIPSREVYENs SHIP OF THE YEAR 2006. The ceremony took place at the SMM 2006 Exhibition in Hamburg in September.
Ulstein Verft AS, Ulsteinvik delivered the first Anchor Handling Tug Supply vessel of the new Ulstein AX104 design on 24 June to Bourbon Offshore Norway AS as the yard’s hull no. 273. M/S «BOURBON ORCA» is designed by Ulstein Design AS. M/V «BOURBON ORCA» is the final product of a collaboration between Bourbon Offshore, Ulstein Design and ODIM and has several special features, like the X-Bow, the Odim SAHS and the Diesel electric propulsion system.
The inverted bow is a striking feature. The bow stemline is pulled back, and the hull reaches the bridge deck. A conventional bow throws a lot of water up and forward, especially in heavier seas. This results in slamming and vibrations throughout the vessel, and the sea can cause damage to the superstructure. When the X-Bow ship enters a wave, the foreship’s submerged volume immediately increases, and the retardation forces are distributed over an extended period of time. This results in lower acceleration/retardation levels. The advantages for the crew with better working and safety conditions and greater comforts in terms of noise, vibration and stability is striking.
Anchor handling may be the most dangerous operation carried out by the service fleet in the oil industry. Involved in the development of the ODIM SAHS (safe anchor handling system) one finds Bourbon Offshore Norway, Ulstein Design and Odim.
In 2004 Statoil invited offshore players to develop solutions for safer anchor handling operations. For each of the hazardous anchor handling operations that Bourbon Offshore Norway identified, the partners developed a safer alternative. The result is a completely new solution involving a new stern.
Ulstein Diesel-Electric Propulsion System
The Ulstein solution eliminates the need for a high voltage system onboard resulting in lower cost and less space needed. The system gives increased manoeuverability, a high degree of redundancy and dynamic positioning capabilities thereby reducing the fuel consumption and the emission levels. The use of frequency converters is a key element.
Bourbon Offshore Norway is the Norwegian division of the french Groupe Bourbon and has at the time of writing 18 vessels in operation and six newbuildings in order. The company is located in Fosnavåg, south of Ålesund.
Groupe Bourbon is one of the giants of the international shipping sector with a total of around 250 vessels at its disposal. With 4,300 employees, Bourbon Offshore has a fleet of 190 modern, powerful and multi-purpose vessels and is preparing for the challenges of tomorrow with more than 90 offshore vessels on order or under construction.
Already present in 23 countries, Bourbon Offshore is expanding its presence in its historic areas of operations, like the North Sea and the “Golden Triangle”, the West Coast of Africa, Brazil and the Gulf of Mexico, and is assisting the growth of its clients in new operating regions like Latin America and Southeast Asia. In 2005, the Bourbon Offshore Division reported revenues of 277.2 million euros, up 24%.
In fact the shipowning company is now the biggest foreign contractor of newbuildings in China measured in number of ships. This includes an order for 36 supply vessels placed with Dayang shipyards in China involving two series of vessels. In addition to China and Norway the company has also gone to India with a number of new orders.
At the end of February in the context of its “Horizon 2010 plan”, Bourbon announced investments of 1.45 billion euros, 85% of which will be devoted to the Offshore Division. In line with its growth strategy in deepwater offshore oil and gas marine services, Bourbon has defined in detail and ordered new, innovative vessels, equipped with the latest technologies to guarantee the best safety conditions during operations. The deliveries and commissioning of these vessels will be staggered from the final quarter of 2007 until the first half of 2009.
And shipbuilding – it was recently announced that Groupe Bourbon was entering shipbuilding through the acquisitin of Piriou which has interests in Nigeria, Vietnam and Brazil in addition to France.
The companies in the Ulstein Group are gathered under the holding company Ulstein Mekaniske Verksted Holding ASA which, in addition to functioning as a holding company, also has the primary objective of business development across the business structure.
Ulstein Verft AS is one of the world’s foremost suppliers of advanced vessels; primarily anchor handling tug supply vessels, platform supply vessels and specialised and multifunctional vessels. The shipyard serves as the Ulstein Group’s development base for the detail design and assembling of capital and equipment intensive specialised vessels and is the Group’s most important expertise base for carrying out projects.
The main yard is in Ulsteinvik, Norway, but there is also a department in Vanylven, Norway, where steel-sections for the main yard are built. The steel intensive components of the hull are manufactured at Maritim-Shipyard Sp. z.o.o. in Poland and production there is followed up by the Ulstein Poland Ltd.
Ulstein Group’s design department, Ulstein Design, was established as an independent company in 2000. Since then an extensive portfolio of Ulstein designs have been developed. The threee series of vessels are Ulstein A series (AHTS), Ulstein P series (PSV) and Ulstein S series (specialised/multifunctional vessels). So far four Ulstein A101 design vessels and five PSV vessels of the Ulstein P103 have been built. In addition five ships are under construction.
