- Emergency Escape Breathing Device (EEBD)
A self-contained breathing device providing approximately 10 minutes of breathable air to escape a smoke-filled space.
- Emergency Fire Pump
A self-contained fire pump located outside the machinery space, capable of supplying fire mains if the main pumps are disabled.
- Emergency Generator
A self-contained standby generator automatically supplying essential electrical power to safety systems if the main supply fails.
- Emergency Position Indicating Radio Beacon (EPIRB)
A satellite beacon that transmits a distress signal with vessel identity and position to the Cospas-Sarsat system when activated.
- Emergency Shutdown (ESD)
Automated/manual system that stops cargo transfer in seconds when a high-level alarm, leak, or other unsafe condition is detected.
- Emission Control Area (ECA)
A sea area designated under MARPOL Annex VI where stricter limits on sulfur and NOx emissions from ships apply.
- EmS Guide
IMO Emergency Response Procedures for Ships Carrying Dangerous Goods; gives Fire and Spillage schedules referenced from the DG list.
- Energy Efficiency Design Index (EEDI)
Design-phase efficiency index (g CO2 per t·nm) required for newbuilds since 2013; tightens in successive phases.
- Energy Efficiency Existing Ship Index (EEXI)
One-off retroactive efficiency index applied to ships built before EEDI; effective 2023.
- Engine Cadet
A trainee engineer officer undertaking approved sea service as part of an engineering degree programme to qualify for a watchkeeping certificate.
- Engine Log
The official daily record maintained by the engine department of machinery performance, fuel consumption, and maintenance events.
- Engine Room Resource Management (ERM)
Engine-room equivalent of BRM — teamwork, communication, fatigue management, situational awareness for engineers.
- Enhanced Group Call (EGC)
Inmarsat-C broadcast service for distributing safety, navigational, and security messages to ships in defined geographic areas.
- EPIRB Categories (EPIRB)
Two categories of 406 MHz EPIRB: Cat I auto-deploy and float-free; Cat II manual deployment.
- Equasis
A free public database providing safety-related information on commercial vessels including inspection history, class, and owner details.
- Escort Tug
Powerful, manoeuvrable tug attached to a tanker via line during port approach to brake or steer if main engine/steering fails.
- Estimated Position (EP)
A position obtained by advancing a known fix using course and speed while applying estimated leeway and current allowances.
- Exclusive Economic Zone (EEZ)
A sea zone extending up to 200 nautical miles from a coastal state's baseline where it has sovereign rights over resources.
- Exhaust Gas Cleaning System (EGCS)
A device fitted in the exhaust line that removes sulfur oxides from engine gases, allowing use of high-sulfur HFO under IMO 2020.
- Exhaust Gas Cleaning System (EGCS)
Scrubber system reducing SOx from exhaust gas to comply with MARPOL Annex VI without using low-sulphur fuel.
- Exhaust Gas Economiser (EGE)
Heat exchanger in the funnel that recovers waste heat from main-engine exhaust to generate steam.
- Exhaust Gas Recirculation (EGR)
NOx-reduction technique that recirculates a portion of exhaust gas back into the engine intake, lowering combustion peak temperature.
