Clean Marine say they have been contracted by Hudong-Zhonghua Shipbuilding in China to supply exhaust gas cleaning systems (EGCS) for two 38,000 dwt. Chemical Tankers being built for Stolt Tankers and NYK Stolt Tankers.
The two vessels are to be built in a series of six sister ships, where the remaining four vessels will be designed with the flexibility to add an EGCS at a later stage. The order will enable these new vessels to comply with sulphur emissions legislation without switching to more expensive fuels.
" For vessels operating in European or US waters, inside the emission control areas (ECAs), a maximum sulphur limit of 0.1 percent will apply from January 2015," says Clean Marine CEO Høy-Petersen. "The Clean Marine system supplied to Stolt Tankers will clean both sulphur oxides (SOx) and particulate matter emissions from one main engine, three auxiliary engines, and three boilers. In total, a single Clean Marine EGCS unit will manage seven exhaust sources and will be designed to clean 140,000 kg exhaust per hour." Installation of the EGCS unit is scheduled to take place during 2015.
Clean Marine explains that its EGCS system is based on the Advanced Vortex Chamber technology that provides unique cleaning efficiency. The system's integrated fan and gas recirculation technology allows the one EGCS unit to simultaneously serve several combustion units.
The system supplied to Stolt Tankers is a hybrid system that allows the vessel to operate seamlessly in all types of water (including low alkaline and saline water) without loss of efficiency. Furthermore, the Clean Marine EGCS meets the current pH limit for washwater discharge in Europe and USA with good margin.
