They are V12 4 stroke high pressure common rail direct injection engines which are turbocharged and inter-cooled, of 24.24 litres displacement. Fitted with MAN supplied SCR catalytic exhaust system using Urea injection to achieve IMO Tier III compliance.

3.2 REVERSE REDUCTIONS GEARBOXES
Reverse, reduction gear boxes are coupled to the main engines via a torsional coupling. Reduction ratio is approximately 3:1

3.3 ENGINE MOUNTING
The engines are resiliently mounted to reduce noise and vibration.

3.4 SHAFT SYSTEM AND PROPELLERS
The shaft line is supported on water lubricated bearings. The propellers are five bladed outboard turning and made from Nickel Bronze Aluminium. They are cast and then CNC machined and balanced and finished to exceed ISO 484/2 class S4.

3.5 SHAFT LINE BEARINGS AND SEALS
The shaft is made from Aquamet 17 or equivalent duplex stainless steel shaft material. The stern tube glands (seals) are of the mechanical drip less type, water lubricated face slip seals.

3.6 ENGINE ROOM AIR SUPPLY
Engine room ventilation is provided by reversible variable speed axial fans to meet the engine manufacturers requirements for air supply and cooling. Air inlets and outlets are fitted with efficient mist and spray elimination systems.

3.7 EXHAUST SYSTEM
The exhausts exit the hull underwater through in-hull sound muffling boxes with a pressure relief slow running bypass installed permanently open and exiting below the lower rub rail (sponson).

3.8 CONTROLS AND INSTRUMENTS
The pilothouse has a MAN engine information panel for each engine which shows engine data including RPM, % Load, Fuel Consumption, Oil Pressure, Coolant Temperature and other relevant data for both engines. 

MAN engine control panels for the engine room are fitted.
