EGCS for Dorian Installed and Approved

The ECO VLGC Corvette, delivered from Hyundai Heavy Industries on 2 January, 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 1 January 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 8 January, 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.

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 USA, UK 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 (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 US 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.

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.”

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. This is why we call it a futureproof solution.

Clean Marine celebrates launch of ground-breaking ‘compact’ scrubber with a seven-system order from Inventor Chemical Tankers

Exhaust Gas Cleaning Systems (EGCS) company Clean Marine has secured a multi-vessel contract from Inventor Chemical Tankers AS (ICT). The agreement, covering seven 19900 DWT chemical tankers, marks the launch of the firm’s revolutionary CleanSOx Compact Hybrid Allstream scrubber to the marketplace.

According to Clean Marine CEO Nils Høy-Petersen, the company has been exclusively dedicated to EGCS solutions since its inception in 2006.

“Our latest product has been designed to ensure ship owners can achieve simple, cost and space efficient compliance with the IMO’s SOx regulations, coming into force in 2020,” he said.

“The new Compact scrubber has all the advantages of our existing, patented EGCS technology, with added benefits for ship owners looking for ease of retrofitting, especially where space is at a premium.”

Mr Høy-Petersen notes that the system’s ‘Allstream’ capability allows it to treat exhaust from all sources onboard vessels with no back pressure in the exhaust system, while its compact design means it delivers very significant size and weight advantages against market alternatives.

“What this means is minimal impact upon the vessel with maximum emission cleaning performance – exactly what the market is looking for.”

Høy-Petersen added: “Our system is simple, compliant, and ensures clean sailing on existing heavy fuels. And with our unique understanding of both EGCS technology and ship owners’ requirements, we are confident we can offer outstanding EGCS solutions to our customers.”

After an exhaustive review of competing EGCS suppliers, ICT has partnered with Clean Marine and Technical Manager Diamond Shipmanagement, to manage the installation and commissioning of the systems aboard seven vessels, built between 2015 and 2017. All vessels were ECO designed and built by the Japanese-based Fukuoka Shipyard.

ICT Chief Operating Officer Torfin Eide said the decision to choose the ‘compact’ solution was driven by a number of factors: “Together with our technical management team, we compared performance, size, weight, price and operating costs of similar products developed by other companies before choosing Clean Marine,” he said.

“Considering parameters such as Allstream, size, weight, design, hybrid technology, and the total associated cost to have it installed and commissioned onboard, we believe we have found the optimal EGCS solution for our chemical tankers. Also, Clean Marine’s compact size for this scrubber means that we can avoid a major retrofit — a significant contributing factor in our decision.”

Mr Eide adds that ICT is committed to minimising its environmental footprint by utilising “green technology”.

“Our investment in this project is a clear demonstration of our efforts to reduce emissions and achieve compliant sailing, well before the 2020 regulations come into force. Our goal is to deliver the best performance and value for all our stakeholders.”
