FAQs & glossary
Answers
Frequently asked
Glossary
- Propulsion train
- The complete system that converts engine or fuel-cell power into thrust, typically including the prime mover, gearbox, shafting, propeller or waterjet.
- Azimuth thruster
- A steerable propulsion unit that can rotate 360 degrees, often used for manoeuvring, dynamic positioning and offshore vessel station-keeping.
- Podded propulsion
- An electric drive where the motor is housed in a submerged pod that also carries the propeller, improving hydrodynamic efficiency and manoeuvrability.
- Hybrid propulsion
- A system combining combustion engines with batteries or other energy storage to cut fuel use, emissions and noise in port and low-load operations.
- Dual-fuel engine
- An engine able to run on conventional marine fuel and a lower-carbon fuel such as LNG or methanol, depending on availability and operating mode.
- Energy Efficiency Existing Ship Index (EEXI)
- An IMO measure setting a required energy-efficiency level for existing ships, driving engine power limitations and propulsion retrofits.
- Carbon Intensity Indicator (CII)
- An IMO operational rating that measures CO2 emissions per transport work; poor ratings can push owners toward efficiency upgrades and slower steaming.
- Shaft generator
- A generator driven by the main engine shaft to supply electrical power at sea, often paired with a power take-in for boost or electric-only mode.
- Controllable pitch propeller (CPP)
- A propeller whose blade pitch can be adjusted in service to optimise thrust and fuel use across different speeds and loading conditions.
- Dynamic positioning (DP)
- A computer-controlled thruster system that holds a vessel on station without anchors, important for offshore, research and service vessels.
- Shore power
- Also called cold ironing, it lets ships shut down engines in port by plugging into the local electricity grid, reducing local emissions and noise.
- Methanol dual-fuel retrofit
- Conversion of an existing engine and fuel system to burn methanol in dual-fuel mode, a candidate pathway for cutting CO2 and sulphur emissions.
