Engines Bergen goes with


MAN power MAN Diesel & Turbo has recently signed a supply contract with Norwegian shipbuilder, Bergen Group Fosen, in Rissa, Norway. Under the terms of the deal, MAN Diesel & Turbo will supply eight state-of-the- art, common-rail-based 10L32/44CR main engines, along with six L21/31 auxiliary generating-sets and four RENK gearboxes for two ferries to be operated by Fjord Line Danmark A/S, the Danish subsidiary of the Norwegian ferry company. Te main engines could optionally be retrofitted to a dual-fuel (DF) version, once the development of the DF type has been completed. Fjord Line reached an agreement earlier this year


with Bergen Group Fosen for the construction of two modern cruise-ferries. Both ferries will have the capacity to carry up to 1500 passengers and 600 vehicles, and will offer daily sailings on services between Norway and Denmark. Te vessels will sail under Danish flag.

Bergen Group Fosen chose the well-proven MAN


32/44 common-rail engines on account of their fuel-efficiency and minimal emissions. The two vessels are due for delivery to Fjord Line in 2012. Hulls will be constructed by Bergen Group’s Polish partner, Stocznia Gdansk, while final completion, assembly and interior work will be carried out by Bergen Group Fosen.

Lifesaving Design-your-own


lifejackets Viking Life-Saving Equipment has launched a new product appealing to the offshore and commercial shipping industries: design-your-own inflatable SOLAS lifejackets. Customers will now be able to tailor their own


solutions for specific working conditions such as those encountered in maritime environments as well as offshore wind power, offshore welding and industrial conditions. The company offers a variety options including


a choice of 180 Newton or 275 Newton buoyancy for those carrying extra weight, e.g. as with tool belts. There’s a choice of three different closure (buckle) types, including an optional integrated harness for offshore wind industry workers. As well as cover materials ranging from durable Cordura, wipe clean covers and even aluminium covers for welders or fire situations. A host of accessories and colours are also possible. All combinations are SOLAS approved, so no matter how the lifejacket is designed, it will fulfill the existing and future SOLAS requirements described in MSC-200(81). Viking, CEO, Henrik Uhd Christensen says the


new lifejackets are just part of the company’s drive to provide flexible and fast solutions to a changing market. “We’ve always offered a choice of models and styles, but if our customers wanted to change any detail of the standard specification it would take a while to get the approvals through. Now, an offshore welder can quickly and easily specify a spark-resistant aluminium covering with a host of personal features, while someone else working in an oily or greasy production area of a platform may prefer some of the same features with a wipe clean cover.”
