Scrubber fitted in Dorian VLGC Corvette meets EPA wash water pH requirements

JANUARY 15, 2015 — Dorian LPG Ltd. (NYSE: LPG), Stamford, CT, has taken delivery of the ECO VLGC (Very Large Gas Carrier) Corvette from shipbuilder Hyundai Heavy Industries.

Corvette is 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.

The ship is fitted with an exhaust gas cleaning system (EGCS) provided by Clean Marine AS, Lysaker, Norway.

Clean Marine says the measurements of exhaust gas emission and washwater criteria are well below the required limits stated in the MEPC guideline 184(59). This ensures compliance with the 0.1% sulfur limit in place in ECAs since January 1 this year. The vessel is also compliant with the stricter US 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 sufur emissions without switching to more expensive fuels.

Scrubber frontJohn Lycouris, Chief Executive Officer at Dorian LPG (USA) 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.

“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 sulfur regulations in ECAs, as well as with the global cap in 2020 in a cost competitive manner.

“We are pleased with the cooperation with Clean Marine during planning, delivery and commissioning of the system, and the Class and Flag State approval process has been quick and efficient.”

The Clean Marine 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 sulfur 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 that can operate seamlessly in both Open Loop and in Closed Loop (zero discharge mode).
