Maritime Comity is the largest zinc-coated MR equipped with an exhaust gas cleaning system on the market and the lead vessel of eight 60,000 m3 shallow draft, scrubber-equipped MR chemical tankers on order from China State Shipbuilding Company for Aurora Tankers.
Aurora Tankers is the shipping arm of the IMC Industrial Group. The Group’s beginnings go back to 1949 when the business was founded in Hong Kong by the late Tan Sri Frank Tsao, before International Maritime Carriers (IMC) was established in 1966.
The IMC Industrial Group started out as a shipping company and that has remained its main focus, although the Group has expanded into other businesses including logistics and ports, marine and offshore engineering, and plantations.
The shipping division comprises three companies active in three distinct sectors: dry bulk carriers (IMC Shipping); chemical/product tankers (Aurora Tankers); and shipping crew management (MSI).
Through the group’s different shipping interests and entities, it had a wide range of experience to call upon when choosing its next direction of investment.
IMC Industrial Group is a traditional first-tier shipping operation, in that it is not active in buying second-hand tonnage.
Of the current 26 vessels spread across the three ship-controlling entities, only one vessel was a second-hand purchase.
Aurora Tankers is based in Singapore and operates a fleet of 19 chemical tankers.
This fleet can be split into three tranches:
the oldest is a pair of 1998-built, 45,300 dwt MR2 chemical/product tankers built at Dalian Shipyard in China; the second group includes eight 44,400 dwt MR2 chemical/product tankers also constructed at Dalian Shipyard between 2001 and 2005; the third tranche was built during 2016 to 2017 at Dalian Shipbuilding Industry Corp (formerly known as Dalian Shipyard) and comprises four 50,000 dwt MR2 chemical and product tankers.
For the latest series of tankers, Aurora Tankers turned to Guangzhou Shipyard International (GSI) in China.
Maritime Comity’s steel cutting commenced on 6 December 2018 with the keel laying taking place on 5 September 2019.
The vessel was launched on 8 January 2020 and delivered on 21 August 2020 as the lead vessel in a series of eight 55,000 dwt, 60,000 m3 chemical/product tankers.
Aurora Tankers Pool has been earmarked for the commercial management of Maritime Comity. The addition of Maritime Comity to the Aurora Tankers Pool will lift the current average age of the pool, which stands at 16-years old.
The remaining six newbuildings are scheduled to be delivered throughout 2021. The series will be operated in the Aurora Tankers Pool, bringing the total MR fleet to 22 vessels.
Aurora Tankers took delivery of its second vessel in the series of eight IMO Type II MR chemical tankers – Maritime Tranquillity – on 30 September 2020. Maritime Tranquility is the third generation of IMO Type II MR chemical tankers designed and managed by IMC’s in-house technical team.
The design has been developed by Aurora Tankers, which has over 20 years’ experience in trading IMO Type II cargo. IMC Industrial Group senior director, shipping, Mr Frederik Guttormsen, said:
“Aurora Tankers’ first newbuilding in this series of eight supports our strategy of growth and will continue to improve our service offering to our customers. The series will be operated in our Aurora Tankers pool, strengthening our position as a leading IMO 2 MR operator.”
Maritime Comity’s cargo arrangements consists of 21 tanks in total. Each cargo tank is zinc coated with PPG supplied coating; 20 of the cargo tankers are below 3,000 m3 and one tank is 1,400 m3. There is also one slop tank (1,100 m3) and one residual tank (230 m3).
Marflex has supplied 23 electric-driven deep-pumps. The tank ullage sensing equipment is supplied by Musasino.
Oxymat was chosen to supply the nitrogen inert gas system to ensure a longer life of the coating and reduced cleaning costs.
Oxymat was chosen due to Aurora Tankers experience with the reliability of the equipment. Consilium supplied the gas sensors and detection equipment. Cargo valve control is handled by Wouter Witzel and the all-important ballast water treatment system is supplied by Sunrui.
The Sunrui BalClor ballast water treatment system is type-approved by the US Coast Guard and has been type-approved to meet the IMO revised G8 requirements, too. The main engine is a WIN GD W6X52 fitted with a low pressure SCR (Tier III).
The power output is: MCR 10,860kW X 105 rpm; CMCR 7400kW X 85.9 rpm; and NCR(CSR) 6290kW X 81.4 rpm. The main engine is fitted with a Clean Marine Scrubber exhaust gas cleaning system. Four auxiliary engines are fitted, consisting of four Yanmar Main D/G producing 1,080 kW each.
The emergency generator provides 150 kW EDG. Also in the machinery space are the boilers. These consist of two Alfa Laval units with a capacity of 15,000 kg/hour and a composite auxiliary boiler with a capacity of 1,200 kg/hour.
Freshwater is provided by one 25-tonne per day capacity Sasakura FWG and a 20-tonne per day capacity Hansun RO Water Maker.
The purifiers are provided by GEA/Wesfalia: two handle heavy fuel oil, one is for marine diesel oil and two are for lubricating oil.
Boll & Kirch has supplied the filters and fuel management is by VAF. The fuel oil shifter is from Hokishin.
The drivetrain consists of a FPP propeller with steerage handled by a Yoowon SG semi-balanced type rudder with rudder bulb.
On the deck, hose handling is accomplished by a 15-tonne Ningbo Kairong hose-handling crane.
The mooring equipment is provided by Wuhan Marine winches and windlasses. On the bridge, the helm is a Yogokawa auto-pilot with navigation equipment, including ECDIS and AIS provided by Japan Radio Company (JRC).
The communication equipment is also provided by JRC. The bridge cargo control monitoring system consists of an Emerson valve remote control system.
Aurora Tankers has chosen VAF Instruments of the Netherlands to provide a vessel performance monitoring system. According to VAF, the system consists of propulsion performance instrumentation and analysis.
The system measures the torque of the propeller over time and this, in conjunction with other instruments, can lead to a 10% reduction in fuel costs, according to the manufacturers.
Maritime Comity is a modern eco design that allows maximised cargo loads with low specific gravity and features a shallow draft design allowing for maximum flexibility for trading and operations.
