Clean Marine has been selected by Hudong-Zhonghua Shipbuilding in China to[ds_preview] 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 built in a series of six sister ships, while the remaining four vessels will be designed with the flexibility to add an EGCS at a later stage, Clean Marine reported. The order will enable these new vessels to comply with sulphur emissions legislation without switching to more expensive fuels.
The Stolt Tankers fleet consists of more than 150 ships and barges and the EGCS should ensure that the new vessels operate well within all applicable local and international regulatory requirements. According to Clean Marine, the company has developed an EGCS based on the Advanced Vortex Chamber technology that provides unique cleaning efficiency. The system’s integrated fan and gas recirculation technology allows the EGCS unit to simultaneously serve several combustion units.
The system supplied to Stolt Tankers is a hybrid system that should allow the vessel to operate seamlessly in all types of water (including low alkaline and saline water) without loss of efficiency. It 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, the manufacturer said. The installation of the EGCS units is scheduled to take place during 2015.
