Beta Marine Perkins-Sabre Generating Sets

Our standard specification includes marine heat exchanger cooled Perkins-Sabre engines. We can also offer both keel / hull cooled engines and (in some cases) radiator cooled engines as an option - prices on request. We include Mecc Alte ‘marine rated’ generators, Newage Stamford (now Cummins Generator Technologies) generators are offered as an option.

Beta Marine Generating Sets - Specifications

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

  • Powered by a Perkins Sabre marine specification heat exchanger cooled auxiliary diesel engine and rated for continuous operation in accordance with ISO 3046.
  • Heat exchanger cooling complete with cupro-nickel tube bundle, with fresh and sea water pumps, including lubricating oil cooler and sump drain pump.
  • Water cooled exhaust manifolds with dry exhaust stub and flexible bellows section.
  • 12 volt electric start system with battery charging alternator and stop solenoid valve. Marine type insulated return.
  • Combined start, alarm and shutdown panel engine mounted and pre-wired to engine components and including: start/stop keyswitch, oil pressure gauge, coolant temperature gauge, tachometer/hours run meter, shutdown on low lubricating oil pressure, high coolant temperature, and overspeed; indicator lamps for faults and power on, provision for connection of customers remote emergency stop.
  • Speed governor to control engine speed to the requirements of ISO 3046 for diesel generating set.
  • Perkins Sabre standard fuel oil, lubricating oil and combustion air filters. Flexible fuel connections.
  • Mecc Alte alternator marine rated to ISO standard, 4 pole, brushless, self ventilated with IP 23 protection, single bearing construction. The generator is self regulating and self excited and is complete with terminal box and automatic voltage regulator, fully suitable for use in engine room environments of 45°C.
  • Engine and generator are close coupled together and mounted on a combined welded steel baseplate.
  • Marine failsafe anti-vibration mountings to isolate the set from the ships seating.
  • Paint: Perkins Sabre Blue and black.
  • 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).

Optional Extras and Alternative Equipment

  • Engine options: Alternative engine cooling options - keel cooling, or radiator cooling with mounted radiator and engine driven fan, (radiator cooled output is slightly derated due to power absorbed by fan). 24 Volt electric starting or air starting, and a second means of starting. Starter batteries. Dry exhaust silencer. Spark arrestor exhaust silencer. Water injection exhaust elbow for wet system. Fuel/water separators. Duplex changeover fuel filters with flexible inlet hose. Double skinned (sheathed) high pressure fuel injection pipes (these are not included in the standard specification).
  • Alternator options: Anti condensation heaters, droop kit, 3 phase sensing etc.
  • Generating set options: 2 bearing generator with flexible coupling drive and torsional vibration analysis. Extra alarm switches for UMS operation. Parallel operation. Automatic mains failure equipment. Extended control panels. Mains output panels etc.
  • Generating sets manufactured to Class: Lloyds Register, Det Norske Veritas, Bureau Veritas, American Bureau of Shipping, Germanischer Lloyd, RINA, etc.
  • Export packing and FOB UK port.
  • All goods are offered and supplied in accordance with our 'General Terms of Tender and Sale'.

Class survey fees, for guidance allow 15%.
Any additional charges for approvals of drawings or calculations by class society will be passed on ‘at-cost’

AC output panels and circuit breakers, not normally supplied on marine sets as these items usually form part of the separate ships switchboard, however we offer as follows:

  • 3 Phase “Over mounting” type panel fitted on generator terminal box and pre-wired to generator terminals with AC ammeter(s), Voltmeter with selector switch, Frequency meter and meter fuses
  • Circuit breaker (MCCB) in enclosure mounted on the set and pre-wired to the generator terminals
Export packing and delivery FOB UK Port

Notes: Alternators are selected to give marine ratings for class ‘F’ temperature rises in marine ambient engine room temperatures of 45°C. Frame sizes may alter to meet required voltage / frequency.
