Hamworthy has completed the acquisition of Krystallon Limited. Fluid handling systems supplier Hamworthy has acquired the company that pioneered gas scrubber development as a commercially viable alternative to costly low sulphur content distillates, to comply with new International Maritime Organization (IMO) MARPOL Annex VI regulations on emissions. Last year IMO agreed the concept of Emission Control Areas, ruling that the maximum sulphur content in fuels used in such zones must be cut to 1.5%, then to 1% by 2012, and to 0.1% in 2015. The regulations are already in force in the North Sea, English Channel and the Baltic. Similarly the US and Canada have applied for ECA status for the waters extending 200 Nm from their coasts. Other countries are expected to follow suit.
