Wärtsilä Hamworthy has won a contract from Fincantieri Cantieri Navali Italiani S.p.A. to supply two Membrane BioReactors (MBRs) to the 141,000gt newbuilding under construction for P&O Cruises.

Hamworthy has delivered more than 25 MBR advanced wastewater systems to the world’s largest cruise ship operator, Carnival. The company’s MBR system produces the highest quality discharge without requiring any addition or generation of chemicals that are hazardous to the environment or vessel operation. For this contract Wärtsilä Hamworthy will also be responsible for UV polishing.

The 3,611 passenger capacity vessel is set to enter service in March 2015. It will be the largest to be constructed for the British market and the order includes an option for a second vessel.

Incorporating a twin-line funnel profile, the newbuilding will reflect the highest technological standards as well as a stylish interior décor.

Kevin Robertson, Sales Director, Wärtsilä Water Systems, said: “Carnival group is once again showing confidence in the ability of Hamworthy’s advanced wastewater treatment technology to meet increasing environmental legislative requirements.”
