2 MAN Diesel & Turbo The responsible way in leading technology MAN Diesel & Turbo is the world s leading designer and manufacturer of low and medium speed engines. Our involvement with electrical power generators goes back to 1904 when we supplied the first ever diesel generator sets to the Kiev Tram System. Since those early days, MAN Diesel & Turbo has never lost its technological preeminence in the large engine field. Likewise, our engines have never relinquished their status as the most efficient combustion engines available. More than ever before, MAN Diesel & Turbo s development focus is on the environmental performance of our engines. Using our unrivalled grasp of large engine technology, we aim to make our engines progressively cleaner, more powerful and more efficient. With our absolute commitment to reducing emissions while increasing fuel efficiency and power density and, with our active partnership in the emissions law making process, we intend to be part of the global emissions solution.

3 Floating Diesel Power Stations For coastal regions or large river sites, floating power stations are an ideal solution for meeting power supply needs on a fast track basis. The advantages are: Simple and straight forward location of power station where power is required. Supports rapid infrastructure development in remote regions. Short building times: for example 70 MW power station can be installed in less than 12 months. Reduced reliance on poor or nonexistent local capabilities. Floating power stations can take advantage of financing incentives from shipbuilding regions. Unaffected by landslides and earthquakes. Minimal environmental impact as only a small area of coastal or up-river land is required. Independence from local infrastructure. The floating Diesel power station can be supplied with two cooling alternatives: sea water cooling or roof-mounted radiator equipment. Minimum operator s investment risk due to the mobility, versatility and adaptability of this type of plant. 4 Floating Diesel power stations Floating Diesel power stations 5

5 72 MW Floating Diesel Power Station Basic design and structure Main deck Upper deck Lower deck Pontoon: Air cooled option Sea water cooled option Main deck Upper deck Lower deck Pontoon Diesel generating sets with cooling water, fuel, luboil separator, nozzle cooling modules, etc. Workshops (mechanical and electrical) and electrical switchgear. The fully equipped, noise-protected workshops and tool rooms mean that maintenance and repair work can be carried out on board. Control room, sanitary and social rooms. The control room is noise-protected, air-conditioned and fire-protected. The social and sanitary rooms are designed to accommodate a crew of 15. Tanks with transfer pumps, fuel processing and seawater pumps. The seawater pump room features a multi-stage filter system for seawater cooling. The tank capacities are designed for approx. two days of operation at 100% load. The fuel processing equipment is housed in separately ventilated and fire proof compartments. With noise-protected engine-house and front-end mounting for the electrical part, control room, open-air substation, sanitary and social rooms. 8 Floating Diesel power stations Floating Diesel power stations 9

8 Transporting and Tank Farm Transportation of a 124 MW floating diesel power station Tank farm Transporting the barge Seaborne transport is via lift ship or towable, submersible transport barge. River-bound transport is by tugs. Waste-heat utilisation The overall efficiency of the power plant can be improved by utilising waste engine heat from the exhaust gas and cooling water, e.g. in a freshwater production system for generating drinking water, both for meeting on-board needs and for supplying drinking water to the local community. Tank farm Usually the tank farm for fuel storage is erected on land, although it can be installed on an additional tanker barge. The use of tanker barges ensures complete independence from the local infrastructure. Fuel is supplied by tanker, tank trailer lorry, barge or pipeline. 14 Floating Diesel power stations Floating Diesel power stations 15
