Dynagas, the liquefied natural gas (LNG) shipping arm of the George Prokopiou shipping enterprises, took delivery of Arctic Aurora, the second of two ice-class membrane LNG tankers, during a ceremony at Hyundai Heavy Industry (HHI) Ulsan shipyard, Korea on July 26th. The first, Yenisei River, was delivered the day before. Both ships are powered by Wartsila-Hyundai dual-fuel diesel engines, enabling operation on either natural gas or marine diesel oil.
The 155,000 cbm (cubic metres) ships are fitted with GTT Mk III containment systems. Propulsion for the ships is provided by a dual-fuel diesel generator engine system. Four Wartsila-Hyundai diesel engines in each ship, fuelled either by gas or fuel oil, will power two propulsion motors driving a single fixed pitch propeller. Registered in the Marshall Islands, the ships will operate on charter to Gazprom and Statoil.
The design complies with Lloyd’s Register (LR)’s Ice-Class and Winterisation Rules for operation under harsh Arctic conditions, and the ShipRight FDA plus notation for a 40-year North Atlantic fatigue assessment. The ships also have been constructed in accordance with ShipRight Construction Monitoring procedures, and built to LR’s Environmental Protection ‘ECO’ notation demonstrating the operator’s commitment to, and investment in, environmentally friendly ships while also featuring an Inventory of Hazardous Materials (IHM).
The LNG carrier contract, established mid-2011, includes an option for a third vessel as well.
