A marine LNG engine is a dual fuel engine that uses natural gas and bunker fuel to convert chemical energy in to mechanical energy. Due to natural gas' cleaner burning properties, the use of natural gas in merchant ship propulsion plants is becoming an option for companies in order to comply with IMO and MARPOL environmental regulations.
The first Soviet mass-produced diesel locomotive, TE3, was powered by a 1470 kW (2000 hp) 2D100 engine, direct descendant of the marine 38 8-1/8 engine. The TE3 was produced in high numbers (up to 7600 units), and proved to be a reliable mainline freight locomotive. Later this engine evolved to the turbocharged 10D100, rated at 2200 kW (3000 hp).
Dual fuel engines are fueled by either marine grade diesel, heavy fuel oil, or liquefied natural gas (LNG). A Marine LNG Engine has multiple fuel options, allowing vessels to transit without relying on one type of fuel. Studies show that LNG is the most efficient of fuels, although limited access to LNG fueling stations limits the production of ...
Combined diesel–electric and gas (CODLAG) is a modification of the combined diesel and gas propulsion system for ships. A variant, called the combined diesel–electric or gas ( CODLOG ) system, contains the same basic elements but will not allow simultaneous use of the alternative drive sources.
The CODLAD propulsion system is based on the use of electric motors directly connected to the axes (generally two) of the propellers. The electric motors are powered by diesel generators and to have higher speeds, as happens in CODAD propulsion systems, the higher power diesel engine is inserted which is disconnected from the transmission system to return to cruising speed.
An example of integrated electric propulsion in the Type 45 destroyer (GT: gas turbine; DG: diesel generator) Integrated electric propulsion (IEP), full electric propulsion (FEP) or integrated full electric propulsion (IFEP) is an arrangement of marine propulsion systems such that gas turbines or diesel generators or both generate three-phase [1] electricity which is then used to power ...
A hydrogen ship is a hydrogen fueled ship, using an electric motor that gets its electricity from a fuel cell, or hydrogen fuel in an internal combustion engine. A hydrogen-powered ship is a vessel that uses hydrogen as its primary source of energy, typically through fuel cells or hydrogen combustion engines, to achieve propulsion. These ships ...
