DHW loop performance control in substations
The jewel liner owned by shipowner CUNARD, ‘QUEEN MARY II’ is an impressive 350 metres long, with 157,000 horsepower, 150,000 tons, 2,620 passengers, 1,253 crew members and, to ensure the thermal comfort of all, whether cruising in the icy waters of the North Atlantic or dropping anchor in the Caribbean, an installation with a heating capacity of 9 MW and a cooling capacity of 22 MW for a chilled water flow rate of 2,700 m3/h.
t was during a stopover on this exceptional liner that the T.E.C. teams had to intervene in a very short space of time, given the operating requirements, to identify the problems affecting the production of chilled water on this giant of the seas.
By drawing up precise and optimised investigation and test protocols, and with full knowledge and control of the centrifugal chilled water production equipment, the T.E.C. teams, with the support of specialist laboratories, succeeded in highlighting the phenomena impacting production.
In this way, T.E.C. has helped to describe and quantify the operating procedures that can be used to put an end to the problems while avoiding any impact on the vessel’s operations.
