DIESEL ELECTRIC ENGINE DETAILS
AKULA has 3 (three) 430kW Deutz engines which drive 3 DC generators which provide power for 1 (one) 816kW MPM (Main Propulsion Motor), they also provide power for the forward DC windlass and the bow thruster.
These engines also drive 3 AC generators which provide the 380v 3 phase and 220v single phase power through all the other systems on board.
In addition there are 2 x harbour generators which provide AC power for the vessel either at anchor or alongside for quieter more efficient generation when the MPM or other DC powered units are not required.
One of the major benefits of a diesel electric system is that the engines/power units do not need to be positioned aft but theoretically anywhere as all one needs is some wiring to go back to the propulsion motor which is situated way aft with a short and much quieter shaft than one which has a long run through the vessel.

Formerly a Dutch navy pilot vessel "Akula" was converted to a world cruising explorer yacht in 1999 at the Vosper Thornycraft shipyard. BMT Nigel Gee provided all naval architecture and structural design for the conversion including the addition of a flight deck and helicopter hangar. Refit work
was completed at Vosper Thornycraft in 1999. A further interior and exterior refit was completed at
H2X in La Ciotat in 2008. Engine overhaul in Malta in 2010. Akula is a wonderful example of a well-kept conversion from her working days as a Dutch Pilot vessel. Originally built in Holland to the highest Dutch naval specification, her condition today reflects her high standard of construction and the maintenance and care that has followed throughout her life until now.
Akula was refitted to accommodate professional helicopter operations and to be able to cruise the most unfriendly of oceans in style, safety and comfort. Akula is equipped with four Vosper stabilizers that assist rough weather heli-operations allowing comfortable landings in up to around Force 6 weather conditions.
Three main diesel electric engines provide single screw propulsion and power. Together with the silenced generators sound (DB) levels compare well with modern day building standards. Stern and bow thrusters allow for ease of maneuvering and positioning.
This vessel, with its sturdy launches and equipment reflects the type of use she was intended for and portrays the feeling of strength and safety with a homely, comfortable atmosphere.
