Ulstein Verft to build two vessels on specYard News // December 21, 2010
Ulstein Verft is to build two PX121 PSVs on spec.
Ulstein Verft is to build two medium-sized PX121 PSVs for a newly established company in the Ulstein Group. The vessels will be delivered in the first quarter and second quarter of 2012.
“We have analyzed the market to make the right choices for Ulstein Group. We strongly believe that there will be an increased demand for this type of medium-sized platform supply vessel, "said Ulstein Group's CEO Gunvor Ulstein.
“On the basis of competence, quality and benchmarking of prices, Ulstein Verft is competitive, and it is an advantage that we can use our own yard to build the first vessels in this series. Ulstein Verft has had attractive delivery time frames as such the ships will be completed at a period where the market will need this type of tonnage."
“We have been focusing on an efficient hull design and a conscious choice of propulsion systems to minimize fuel consumption and emissions. The vessels are built with the X-BOW hull design that is particularly well-suited for this type of vessel."
"A bow of this type will in good weather offer the same efficiency as a traditional bow with a bulb, but over a large variation in depth foregoing. This is particularly important for vessels that operate with varying loads such as a PSV often does."
"In addition, the X-BOW has unique characteristics in terms of motion and propulsion efficiency in heavy seas, and this is a positive contribution to the well-being on board, as well as efficiency," says Tore Ulstein, head of Ulstein Design & Solutions.
“Ulstein Verft´s order book is now filled until end of summer 2012. These are important contracts, which contribute to fill our capacity," said the company's managing director of Ulstein Verft, Karsten Sævik.
The ships have a length of 83.4m and beam of 18m. They have a cargo deck of 875m2 and loading capacity of 4,200 tonnes.
With good tank capacities and a flexible, segregated arrangement, the multi-function vessels will be able to undertake a variety of contracts.
The hull and propulsion have been selected with the North Sea in mind. The ships meet the requirements of Clean Design, and have treatment systems for ballast water and are prepared for fire-fighting class Fi-Fi 2.
Beyond the usual tanks for oil, water and drilling fluids, the vessels have four stainless steel tanks for flammable liquids, such as methanol. They will reach a speed of at least 15 knots, but the vessels are optimized for low fuel consumption at a speed of 12 knots. They are equipped for 24 persons in 17 cabins, with modern accommodation. The two ships will be build numbers 291 and 294 at Ulstein Verft.
