MTU Marine Diesel Generators

MTU Marine Diesel Generators

Our standard specification includes marine heat exchanger cooled MTU engines with fully classifiable specification. Keel / hull cooling is also available – prices on request (marine radiator cooled engines are not available from MTU). We include Mecc Alte ‘marine rated’ alternators. Newage Stamford (now Cummins Generator Technologies) alternators are offered as an option.

Included in the Generating Set Price

Fully classifiable specification suitable for survey including, duplex change over fuel filters and flexible fuel connections for inlet and return, fire retardant and ‘type’ approved. Double skinned (sheathed) fuel injector pipes. UMS specifications, etc. All engines are IMO Tier II emission compliant with technical file and EIAPP certificate included. The “Standard Specification” of the generating set is listed below. Alternators are selected to give marine ratings for class ‘F’ temperature rises in marine ambient engine room temperatures of 45°C. Frame sizes selected may be pushed into class H temperature rises for lower voltage ratings.

Visa Energy Marine Generating Sets – Specifications

Marine Generating Set having a continuous rated “Prime” power output, 3 phase, at 0.8PF, with a capability for 10% overload in accordance with ISO standard; designed, built and tested by Visa Energy Marine Limited, each comprising:

  • Powered by a MTU model as per price list water cooled 4-stroke diesel engine having vee twelve cylinders, turbocharged and rated for continuous operation when running at 1500 rev/min for 50Hz or 1800rpm for 60Hz. Suitable for operation in ambient temperatures up to 45°C, sea water 32°C, RH 80% and 760mm H2O. The engine will be subject to makers standard bench tests. Type approval certificate.
  • Sea water cooling using engine mounted heat exchanger cooling equipment complete with fresh water make-up tank, thermostat, sea water pump and fresh water pump. Water cooled exhaust manifolds.
  • 24 Volt electric start system with battery charging alternator and stop solenoid valve. Marine type insulated return.
  • Temperature sensors for lube oil, coolant, intake air, charge air, fuel, exhaust A & B. Pressure transmitters for lube oil, coolant, charge air, fuel. Protection sensors low lubricating oil pressure, high jacket water temperature and speed. Level monitors for coolant, fuel leakage and pressure monitor for differential oil filter pressure. Governor for generating set suitable for single and parallel operation. Engine mounted ECU and EMU pre wired to engine components. System cables from ECU and EMU to LOP. All suitable for marine class.
  • Local Operating Panel: MTU local control panel (LOP) for electronic monitoring and control of the engine with alphanumeric colour display of measured values and alarm reports, combined control elements for; ready for operation; local operation; engine start; engine stop; engine emergency stop; engine speed increase; engine speed decrease; engine overspeed test. The panel is supplied loose with plug connectors for mounting near the engine on a bulkhead or may be mounted on the generating set if preferred. The panel is prepared for binary and analogue inputs and outputs.
  • Speed governor to control engine speed to the requirements of ISO 3046 for diesel generating set.
  • MTU standard fuel oil, lubricating oil and combustion air filters suitable for marine class.
  • Mecc Alte alternator marine rated to ISO standard, 4 pole, brushless, self ventilated with IP 22 protection, two bearing construction. The generator is self regulating and self excited and is complete with terminal box and automatic voltage regulator, droop circuit ct, fully suitable for use in engine room environments of 45°C. The generator will be subject to makers standard bench test. Type approval certificate.
  • Engine and generator are close coupled together with flexible coupling and mounted on marine failsafe anti-vibration mountings to isolate the set form its combined welded steel baseplate.
  • Paint: Cobalt blue RAL5013.
  • Each generating set is “full load” tested in accordance with our quality document QA001. On turbocharged engines load acceptance is limited in accordance with ISO 3046.
  • Paint: Cummins white.
