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).
The Deltic-powered Hunt-class mine countermeasures vessel HMS Ledbury. Development began in 1947 and the first Deltic model was the D18-11B, produced in 1950. It was designed to produce 2,500 hp (1,900 kW) at 2000 rpm for a 15-minute rating; the continuous rating being 1,875 hp (1,398 kW) at 1700 rpm, based on a 10,000-hour overhaul or replacement life.

Straight-six engines typically use a firing order of 1-5-3-6-2-4. However, a firing order of 1-2-4-6-5-3 is common on medium-speed marine engines. V6 engines with an angle of 90 degrees between the cylinder banks have used a firing orders of R1-L2-R2-L3-L1-R3 or R1-L3-R3-L2-R2-L1. Several V6 engines with an angle of 60 degrees have used a ...
The General Electric LM6000 is a turboshaft aeroderivative gas turbine engine. The LM6000 is derived from the CF6-80C2 aircraft turbofan. It has additions and modifications designed to make it more suitable for marine propulsion, industrial power generation, and marine power generation use.
Placing the cooling radiator section in seawater rather than ambient air allows for the radiator to be smaller. The engine's cooling water may be used directly or indirectly for heating and cooling purposes of the ship. The Stirling engine has potential for surface-ship propulsion, as the engine's larger physical size is less of a concern.
For an example the new CODAG-propelled Fridtjof Nansen-class frigates of the Royal Norwegian Navy, the gear ratio for the diesel engine is changed from about 1:7.7 (engine:propeller) for diesel-only to 1:5.3 when in diesel-and-turbine mode. Some ships even have three different gear ratios for the diesel engines — one each for single-diesel ...
A CODLAG system employs electric motors which are connected to the propeller shafts (usually 2). The motors are powered by diesel generators.For higher speeds, a gas turbine powers the shafts via a cross-connecting gearbox; for cruise speed, the drive train of the turbine is disengaged with clutches.
140-ton – also described as 135-ton – vertical triple-expansion engine of the type used to power World War II Liberty ships, assembled for testing prior to delivery. The engine is 21 feet (6.4 meters) long and 19 feet (5.8 meters) tall and was designed to operate at 76 rpm and propel a Liberty ship at about 11 kn (13 mph; 20 km/h).
