Clean Marine to Supply Exhaust Gas Cleaning Systems for NYK Stolt Tankers

The two vessels are 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. Nils Høy-Petersen, CEO in Clean Marine, states that the contract reflects the growing demand for Clean Marine’s unique and competitive multi-stream EGCS solution. “We are very pleased to experience a breakthrough also in the Chinese shipbuilding market and to be selected by Hudong-Zhonghua, a yard which during its 70 years history has delivered over 3,000 quality ships. We also look forward to delivering a cost-effective solution to help Stolt Tankers comply with the new emissions regulations which comes into force from 2015”, he says.

Stolt Tankers operates globally and has one of the world’s largest and most sophisticated fleet of chemical tankers. The Stolt Tankers fleet consists of more than 150 ships and barges. Stolt Tankers have a strict focus on safety and environmental protection, and the EGCS from Clean Marine will ensure that the new vessels operate well within all applicable local and international regulatory requirements.

Clean Marine 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 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.

“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 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.
