Major order from Dubai for nitrogen systems
The 45,000 dwt IMO type 2 product and chemical carriers are scheduled for delivery by SLS Shipbuilding between January 2011 and June 2012.
“The contract, which was worth in excess of £6 million, was significant for an inert gas systems agreement” said Morten Letnes, marine business unit director at Hamworthy Moss. “This has been a successful project, with invaluable support from Hamworthy’s sales offices in Dubai and Korea, enabling us to secure our largest single order for nitrogen generator systems”
Each nitrogen generator will have a capacity of 3.750 Nm3/h at 95% purity. Nitrogen gas is distributed to cargo oil tanks and slop tanks. The generator will also supply nitrogen to the ballast water tanks for inerting and gas freeing.
UACC said that its latest ships had been designed for maximum operational flexibility. The 183m long, 32m wide vessels will feature 22 cargo tanks apiece, of up to 2,000m3 capacity each.
UACC vice president – technical, Johan Thuresson said: “It is fair to say that these ships will be our most sophisticated newbuildings to date. We have specified Hamworthy in the past as a supplier of engine room pumps and sewage systems, but this is the first time for us with their nitrogen generator system. We selected Hamworthy based on their global support network and the quality of equipment.”
Hamworthy claims to be well known in the marketplace for its inert gas systems and has over 1500 systems in the field. The latest nitrogen generator is a compact, high efficiency system based on air separation, using hollow fibre membrane modules, which are either cabinet or skid mounted.
Its control system is based on programmable logical control (PLC) technology and features a touch screen type control panel. Several mimic flow diagrams are implemented as well as the controls required for safe operation with a minimum of operator supervision.
