The ECO VLGC Corvette, delivered from Hyundai Heavy Industries on January 2, 2015, is fitted with a Class and Flag State approved exhaust gas cleaning system (EGCS) provided by Clean Marine.
The measurements of exhaust gas emission and washwater criteria are well below the required limits stated in the MEPC guideline 184(59). This ensures vessel compliancy with the 0.1% sulphur limit in ECAs, which has been in place from January 1 this year. The vessel is also compliant with the stricter U.S. EPA requirements of a pH above 6 in washwater, measured at the outlet.
The vessel’s Class Society ABS, on behalf of the Bahamas Flag, issued a formal letter on January 8, 2015, confirming that the EGCS complies with “Scheme B – EGC System Approval, Survey and Certification Using Continuous Monitoring of SOx Emissions” of the IMO Resolution MEPC.184(59), 2009 Guidelines for Exhaust Gas Cleaning Systems
The approved EGCS will enable the new Dorian LPG vessel to comply with current and future legislation relating to sulphur emissions without switching to more expensive fuels, Clean Marine noted.
Dorian LPG is a liquefied petroleum gas shipping company and a leading owner and operator of modern VLGCs. Dorian LPG currently owns and operates six modern VLGCs and one pressurized LPG vessel. In addition, Dorian LPG has 16 ECO VLGC newbuildings under construction. Dorian LPG has offices in U.S.A., U.K. and Greece. Corvette, Dorian's third newbuilding delivery, will initially trade in the spot market and is the first of 15 deliveries that the company expects in 2015.
John Lycouris, Chief Executive Officer at Dorian LPG (U.S.A.) said, "Dorian LPG is proud to be the first within the gas carrier market to install the Clean Marine EGCS and we look forward to trading the Corvette with the considerable technological and environmental advantages over similar vessels in the market.”
Lycouris continued, “The hybrid EGCS delivered by Clean Marine to Dorian LPG vessel Corvette is an advanced solution compliant with the stricter washwater regulations in U.S. waters. We are confident that EGCS will play an important role in moving the shipping industry to comply with the new sulphur regulations in ECAs, as well as with the global cap in 2020 in a cost competitive manner.
Clean Marine and Dorian collaborated during planning, delivery and commissioning of the system, Lycouris said, adding that the Class and Flag State approval process was quick and efficient.
Clean Marine offers a proven, futureproof EGCS which enables vessels to trade in all waters and ports well within the IMO and local regulations. The system’s integrated fan and gas recirculation technology allows one EGCS unit to simultaneously serve all combustion units, including the boilers – this Allstream feature is valuable and cost-efficient for vessels with many exhaust sources.
The Clean Marine system onboard the Corvette cleans both sulphur oxides (SOx) and particulate matter emissions from the main engine, three auxiliary engines, and one boiler. In total, a single Clean Marine EGCS unit will manage five exhaust sources and clean 140,000 kilograms exhaust per hour.
The system supplied to Dorian LPG is a hybrid type which can operate seamlessly in both Open Loop and in Closed Loop (zero discharge mode). Clean Marine’s EGCS features a unique particulate matter trapping efficiency and meets the pH limit for washwater discharges with good margin, causing Clean Marine to call it a “futureproof” solution.
