Schottel Going Full Speed Ahead
Schottel ended the year 2003 with record sales. With 550 employees worldwide, the company continued the previous year’s trend, achieving sales in the new systems and service sectors totalling 90 million euro (2002: 81 million). Sales for the group were thus increased by 11%, and once again exports accounted for some 80% of the total. The extremely satisfactory volume of incoming orders in the last 12 months, amounting to some 88 million euro, means that 42 million euro of orders are on hand for the year 2004. Of particular significance are the latest worldwide sales successes in the areas of tug propulsion systems, offshore supply vessels, cruise ships, research vessels, ferries and military vessels.
Feature: Schottel Broadens Electric Propulsion Options
German engineers have strengthened the Schottel offering through the development of a propulsor which melds technical design and performance features of the company's proprietary, azimuthing Rudderpropeller series with those of electric podded drives. The resulting hybrid system, known as the Schottel Combi Drive (SCD) and distinguished by its compactness and inboard placement of the integral electric motor, has been designed for unit power applications in the 1,900 to 3,800-kW range. The innovative new product employs proven mechanical elements from the Rudderpropeller design and the latter's optimized-efficiency, Twin-Propeller (STP) version.
Deck Machinery
Research Winches for R/V Maria S. Seven special winches were supplied by Hatlapa in December 2003 after being tested and demonstrated in the factory. These winches are intended for the new research vessel Maria S. Merian, which will support the vessel Polarstern during operations in the Arctic. Hatlapa has escorted this project for five years, during which time the design of the winches was formed in close cooperation with the order principal BAW (Bundesanstalt für Wasserbau) and the shipyard Krögerwerft in Rendsburg. One specialty is the combination of friction and storage winch for handling the very long and relatively thin measuring cables. The advantage is that the sensitive and expensive research ropes can be spooled on the storage winch free from load.
MAN B&W Hits New Milestone in Emission Control
MAN B&W Diesel A/S, Holeby, Denmark, has recently tested and supplied a package consisting of two 8L21/31 and two 6L21/31 GenSets. These GenSets will power an advanced Diesel-Electric research vessel for the State Ministry of Education & Science of Mecklenburg-Vorpommern, Germany. The vessel, Maria S. Merian, is now under construction at the Lürssen-Krögerwerft, Rendsburg, Germany, and is scheduled for delivery towards the end of the year. ‘Blue Angel’ is a German standard for environmentally friendly technology, which covers a wide range of subjects. In the marine world, ‘Blue Angel’ has a comprehensive set of rules, including exhaust emission from diesel engines. ‘Blue Angel’ only allows a NOx emission of 80% of the IMO limits.
