Wärtsilä - The most complete offering in the marine business

HMS Queen Elizabeth

The HMS Queen Elizabeth is the largest ship ever built for the Royal Navy. The prime movers selected for the generating sets are two 12-cylinder and two 16-cylinder Wärtsilä 38 engines for each ship. (photo courtesy of BVT)

They will supply 40 MW of the total installed power of over 100 MW, the remainder coming from two gas turbine alternators. Wärtsilä engines were selected for their durability, reliability, cost-efficiency, extended interval time between maintenance, and full compliance with current and foreseen emission regulations.

The HMS Queen Elizabeth is fitted with Wärtsilä Hamworthy Advanced Waste Water Processing Membrane Bioreactor MBR200N which is based on biological degradation and membrane separation. The system allows for the treatment of grey and black water to satisfy the most stringent standards. The process produces the highest quality discharge without requiring any addition or generation of chemicals that are hazardous to the environment or ship operation.

The HMS Queen Elizabeth is also equipped with M series stern shaft seals. An innovative wrapped bellows design, incorporating fully or partially split assemblies, enables installation and service of the equipment without the need to remove the propeller or tail-shaft.

The new Queen Elizabeth-class carriers will give the UK the ability to project military power more than 700 nautical miles, over land as well as sea, from anywhere in the world. The HMS Queen Elizabeth and HMS Prince of Wales will be the largest warships ever built in the UK, and the most capable aircraft carriers outside of the U.S. Navy.
