Cathelco BWT system installedon MV EddystoneAs shipboard testing proceeds, the principal aim is to achieve IMO approval,but as Robert Field explains, this phase of the programme also provides theopportunity to fine tune the system ready for commercial production.In August, Cathelco installed a 400 m 3 /hr BWT system on the ‘MV Eddystone’during a scheduled refit at theRemontowa yard in Gdansk, Poland.The ‘MV Eddystone’, built in 2002, isa 23,000 tonne ro-ro vessel owned byForeland Shipping and managed byAndrew Weir.“The project is on target and everythingwe have done up to this point has beensuccessful. We are confident of gettingIMO approval by the middle of nextyear”, said Robert Field, group technicalmanager at Cathelco.The key to the successful installationon board the Eddystone was theamount of planning which took placebefore anyone set foot on the ship. Thisinvolved a comprehensive survey ofthe installation area, the preparation ofdetailed drawings and discussions withthe owners regarding the logistics andtimings.As the installation took place in a ‘voidarea’ on the vessel, it was necessary tobegin by erecting temporary staging toprovide safe access for the installationteam before moving on to build thepermanent staging.“We discussed various logistic routesfor getting the BWT equipment onboard and in this particular case,because of other refitting work, the bestoption was to cut an aperture in theside of ship to allow the equipment tobe put directly into position within an 8hour time frame”, said Robert Field.An important aspect of the installationwas the successful integration of theBWT control systems with the existingballast water system.“At a very early stage we talked to theengineers who supplied the existingballast water system and brought themin as part of the team”, said Mr Field.“In this way, we were able todo a considerable amountof the software integrationbefore we went aboard thevessel. When we arrived inGdansk it was only necessaryto carry out the final checksand commissioning”, headdedWith everything proceeding smoothly,the installation time for the system was12 days with an additional 4 days forcommissioning. The aim is now toreduce the installation time to 8 days.“I would particularly like to thank theAndrew Weir team and Remontowashipyard for their assistance with theproject”, said Mr Field.Shipboard testingOver the coming months anindependent IMO approved scientificteam will board the MV Eddystone atvarious ports of call to take samples ofthe ballast water for testing.UV chambersMV Eddystone in dock4
