Germany-based TGE Marine Gas Engineering has secured a contract from Japanese shipbuilder Mitsubishi Heavy Industries (MHI) to deliver two complete liquefied natural gas (LNG) fuel systems to be equipped on two new-build cruise ships.

MHI is currently building two new-generation cruise ships for Carnival’s German cruise firm AIDA Cruises at its Nagasaki Shipyard & Machinery Works.

Each 124,500dwt vessel will have the capacity to accommodate around 3,300 passengers and are scheduled for delivery in March 2015 and 2016.

According to TGE, the new ships will be the first cruise vessels to be equipped with dual-fuel engines, allowing the ships to operate on both conventional fuels as well as LNG, depending on its availability at the port.

The new cruise ships will feature advanced environmental technologies such as the Mitsubishi Air Lubrication System (MALS), which is expected to reduce fuel consumption by about 7% and cut carbon dioxide (CO2) emissions through the use of a layer of air bubbles blown from the vessel’s bottom.

Earlier in July 2013, Caterpillar Marine Power Systems delivered its first MaK M 46 DF dual-fuel marine engine to MHI to be equipped on one of the new vessels.

The ships will be powered by three conventionally-fuelled 12 M 43 C marine engines.

According to Caterpillar, the new engine, which is capable of changing from gas to diesel mode during operation, allows reliable vessel operation in different geographical areas, whether using gas, marine diesel oil (MDO) or heavy fuel oil (HFO).

In gas mode, the engine offers optimised fuel consumption in compliance with IMO Tier III and EPA Tier 4 limits.
