South Korea’s Daewoo Shipbuilding & Marine Engineering (DSME) has signed new contracts to build four vessels, including two ME-GI engine-powered liquid natural gas (LNG) carriers, and two very large crude carriers (VLCCs) for Maran Gas Maritime and Maran Tankers Management.

The deal includes a number of options for both the ship types.

Maran Gas Maritime has already placed an order for four ME-GI powered LNG carriers to DSME.

"Compared to a standard LNG carrier, this engine type increases fuel efficiency and reduces emissions."

The company is the LNG shipping company of Greece-based shipowner Angelicoussis Shipping Group, and Maran Tankers Management is the tanker unit of Angelicoussis.

The newly ordered LNG carriers are scheduled for delivery in 2019, while the VLCCs are due in the first half of 2018.

With a capacity of 173,400 cubic metres (cbm), both the LNG carriers will be 295m in length with a breath of 46m.

Each of the carriers will be fitted with MAN B&W 2 x 5G70ME-C9.5-GI gas and fuel burning engines, fulfilling IMO Tier III compliance by EGR in both gas and fuel mode.

Compared to a standard LNG carrier, this engine type increases fuel efficiency and reduces emissions.

The new VLCCs will have 318,000 deadweight tonnage (dwt) capacity and will feature a length of 336m and a breadth of 60m.

Each of the VLCCs will be powered by a single MAN B&W 7G80ME-C9.5 engine equipped with new fuel saving technologies and an exhaust gas recirculation system ensuring Tier III compliance.

Developed by MAN Diesel & Turbo, ME-GI dual fuel low-speed diesel engine provides shipowners and operators the option of using either heavy fuel oil (HFO) or gas, mainly natural gas, to run their ships.

Last month, MAN Diesel & Turbo had secured an order to supply fixed pitch Kappel propellers, propeller boss caps with fins, and engine-power limitation for two container vessels of Danaos Shipping.
