more than 450 seats. Air conditioning throughout has been supplied by Koja Marine, the Finnish company that additionally has contracts to install equipment on Galaxy's sister and on the new Tallink fast ferry that will be built at Aker Finnyards' Helsinki complex. Compared with the previous ship, public spaces have been re-arranged. The conference area has been moved from deck 9 aft to the forward end of deck 5. The discotheque is now placed aft on deck 10 (moved from deck 7). Passenger saunas with a swimming pool are on deck 2 amidships, and the numbers and types of restaurants have been changed. Galaxy has nine lifts, all supplied by MacGregor, which also supplied six lifts each to Victoria and Romantika. There are five passenger lifts, each for 16 people or a load of 1200kg, together with one 1200kg service lift,

and two 1500kg or 20-person capacity service lifts. All use Kone's compact MiniSpace technology and have a service speed of 1.0m/sec The MacGregor Group was acquired by Kone
Corp in December 2004 and Kone Group's marine elevator business is today handled by Kone Marine, whereas MacGregor is now part of the separately listed company Cargotec. The new cruise-ferry has 1130lane metres on one level for both private cars and lorries. As on the earlier vessels, propulsion is provided by four Wärtsilä 16V32 diesel engines totalling 26,240kW. These are connected in pairs to two shafts driving Kamewa CP propellers. Auxiliary power is provided by three Wärtsilä 6L32 diesel engines driving 2960kVA Leroy Somer alternators as well as by two Leroy Somer gear- driven alternators (2 x 2700kVA). The service speed will again be 22knots. Catalytic exhaust- gas units, supplied by
Wärtsilä and
manufactured by H+H Umweld und Industrie Technik GmbH, are installed for reducing NOx emissions.
Hi-Fog MT4 - Marioff's newest concept for machinery-space fire protection
water-based local fire extinguishing, in category A machinery spaces larger than 500m3
A in volume, on
all existing passenger ships of 2000gt or more. Since July 2002, a similar requirement has already been in force on new passenger ships with a gross tonnage exceeding 500gt, and on cargo vessels exceeding 2000gt; this complements the mandatory CO2
or other type of total flooding
system. Statistically, most fires start in the engineroom. Compared with CO2
bottles, water-based
firefighting systems can be released immediately, without having to evacuate a space, thus saving valuable time in the case of local fires. These new
RECENT major SOLAS improvement in fire safety was the requirement to have fixed
regulations, requiring mandatory sprinkler systems, have kept Marioff busy over recent years. Some 200 Hi-Fog watermist retrofit installations have been made for cruise ships and ferries since the year 2000.
The principal benefits of using water only to extinguish fires in enginerooms have lead Marioff to develop its own version of a total fire protection layout, which the company calls Hi-Fog MT4. This system has successfully passed the latest IMO fire test requirements, as defined in MSC/Circ. 1165, adopted in May 2005. Classification society type-approvals have already been issued by the major classification societies. With Hi-Fog MT4, water-based total flooding fire protection is now available for vessels with

machinery spaces of approximately 4000m3 size, with a ceiling height up to 11m. The concept uses using a pump unit only - no pressure cylinders are required for redundancy or other purposes.
The system has been designed to provide both total flooding and local application, using the same pump unit, tubing, and spray heads. One particular additional benefit with water-based systems is that they can be tested regularly, to ensure proper working condition and to demonstrate operation to a crew. In addition to the passenger ship market, Marioff aims to penetrate the cargo ship sector with this new product. The first contracts have already been signed.
