Propulsion Wärtsilä and MHI
renew agreement Wärtsilä and Mitsubishi Heavy Industries Ltd (MHI) have signed a ten-renewal of the existing co-operation agreement for the sale, manufacture and service of Wärtsilä low-speed marine diesel engines. Te licence co-operation agreement is a basis for
exchanging diesel-engine technology between Wärtsilä and Mitsubishi, defining and regulating intellectual property rights, and the delivery and feedback of technical information and support. Such licence agreements allow synergies to the
participating companies of aggregating research, development and design with the licensor while distributing and localising manufacture to licensees in separate countries. Besides building Wärtsilä-designed engines,
Mitsubishi has over the years also contributed to the development of Wärtsilä low-speed engines and oſten built the first examples of new engine types. Tis long co-operation led more recently to successful joint development of the Wärtsilä RT-flex50 and Mitsubi- shi UEC50LSE two-stroke engine types. A joint project was agreed in 2008 between Wärtsilä
and Mitsubishi for the design and development of new small, low-speed marine diesel engines of cylinder bores of 350mm and 400mm and a power range of 3500kW–9000kW. Mitsubishi is taking an important role in this project based on its successful experience in this small-bore-sized engine range. Each engine is available as Wärtsilä RT-flex electronically controlled common-rail and Wärtsilä RTA mechanically controlled engine types. Based on the RTA engine designs with these two bore sizes, Mitsubishi is developing its own UEC-LSE series engines.
Interiors Tailor-made pilot
seats add comfort Newly established Norwegian company Alu Design & Services AS has announced the launch of AluTech 500, a new ergonomical pilot chair that combines technology, comfort and style, resulting in a tailor- made ship-bridge work station. Einar Ulrichsen, chief executive officer of Alu
Design & Services AS, said: “Functionality, design and price are the leading success factors. [Although the product range was only launched this year] we have received several orders from leading offshore, ferry and merchant marine operators and shipyards. We are witnessing a growing interest by international
8
shipowners and planning international expansion.” Te concept behind AluTech 500 was to create a
design that blends simplicity, appearance and usability. Te AluTech pilot chair is reported to deliver a smooth, balanced support throughout the recline, upright and forward tasking positions and is designed to respond to each user’s sitting and work style/back support needs. Alu Design & Services AS is able to deliver units
within a 14-day work period, providing specifications are made available.
Vessel construction Lightweight rescue
boat launched Brude Safety AS has announced that it has completed the design and construction of a new fast rescue boat, HD720 ASI, built in seawater-resistant aluminium and divided in to four watertight compartments. Compared to using expanded foam, this design is said to be more environmentally friendly and is claimed to have several advantages, such as lower weight, no fungal, easy inspection, no inside corrosion and, easier maintenance and repair. Te rescue vessel is 7.2m loa and 2.4m wide and
features excellent manoeuvrability and reliability, as well as sea-keeping abilities but is also designed for other applications, such as serving as a dive support vessel, a patrol boat or being used for other work-boat related duties. Te vessel has a low weight of 1890kg and an impres-
sive payload. While it is designed for a capacity of 6 persons, it can carry up to 15 persons. It is designed and built according to safety of life at sea (SOLAS) 83, amendment 96, life-saving appliances (LSA) code. Te propulsion arrangement consists of a 220hp
Bukh + Steyr SOLAS 236 and an Almarin 230 waterjet, providing a speed of 34kts with 3 persons onboard and a bollard pull of 450kg.
Propulsion HJ exceed
expectation A Korean Coast Guard (KCG) vessel, powered by a pair of HT1000 waterjets, has exceeded its target speeds during sea trials, New Zealand-based waterjet manufacturer, HamiltonJet has reported. Te first pair of HT1000 waterjets, each with an
impeller diameter of 1.2m, was delivered to Korea and sea trials commenced in November 2008. Te units have now completed sea trials and entered service in a 55m loa Korea Coast Guard (KCG) patrol vessel. HamiltonJet’s latest offering, the HT1000, is the
