May 2006 45 Any 'out of specification' levels were detected by the NalTrak 3200, which is illustrated by a dramatic spiking on the trend graph. The unit responded rapidly with an automated application of Nalfleet oxy- gen scavenger. The return condensate pH trend graph showed that the con- trolled application of Nalfleet corrosion inhibitor maintained the condensate pH within the target ranges of 8.5 to 9.5. Circle 5 on Reader Service Card Sea Water Scrubber Installed on Ferry Krystallon - a joint venture between BP Marine and Kittiwake - together with P&O Ferries, recently announced the development and installation of the first Krystallon sea water scrubber on board a commercial vessel, P&O's Pride of Kent passenger ferry, which sails on the Dover to Calais route. Initial results indicate no measurable SO2 emissions after the scrubber despite using a 2.0%S fuel. The Krystallon sea water scrubber test results are not only below the level required by the IMO's SECAs (Sulfur Emissions Control Areas), which allows emissions of 6g/kW/hr. of SO2, but they may even comply with the more strin- gent in port requirements of the European Union, which will come into force in January 2010. "P&O Ferries has led the field in sup- porting this pioneering work and has underlined its commitment to environ- mental policy in reducing emissions of SO2 both at sea and in the ferry ports they use," said Don Gregory, Director, Environment and Sustainability at BP Marine. "With SECAs requiring sulfur emis- sions of maximum 1.5 percent, sea water scrubbers may be the cheapest long term solution for vessels spending a significant portion of their time in the SECA. Sea water scrubbing from Krystallon enables vessels to reduce sulfur emis- sions without requiring changes of fuel or modification to engine design. The results of our first shipboard installation have been dramatic and even more suc- cessful than we had anticipated. Although the Pride of Kent was using a two per cent sulphur fuel the initial analysis could not detect any sulfur oxide emissions after the sea water scrubber was installed. We can therefore conclude that the sea water scrubber will be able to easily meet its design performance criteria of 95 percent scrubbing efficiency."
