Introduction
Joining a ship as a junior engineer can be both exciting and overwhelming. The transition from classroom learning to real-life maritime operations requires adaptability, attentiveness, and a willingness to learn fast. Senior engineers may not always have time to train newcomers in detail, so it’s essential for junior engineers to proactively observe, ask questions, and master practical tasks early.
This guide lists 17 vital things every junior engineer should learn when joining a ship, helping you gain confidence, efficiency, and respect among your peers at sea.

1. Familiarize Yourself with the Ship
Your first task onboard is to explore and understand the vessel. Learn the ship’s layout—engine room, deck, accommodation areas, cargo holds, control room, and emergency exits. The faster you familiarize yourself with your surroundings, the more comfortable and efficient you’ll be during operations or emergencies.
2. Know the Escape Routes
Safety should always come first. Study all escape routes and emergency exits as soon as you board. During an emergency, knowing your way to muster stations or lifeboats without hesitation can save lives. Practice these routes until they become second nature.
3. Locate Important Valves and Pipelines
One of your first duties as a junior engineer will be tracing pipelines and identifying valves. Learn where vital systems—fuel, seawater, bilge, and cooling lines—are located. This knowledge helps during maintenance, isolation procedures, and emergencies.
4. Identify the Designated Person Ashore (DPA)
Every ship has a Designated Person Ashore (DPA) who ensures safe operations and compliance with maritime laws. Knowing who your DPA is allows you to report safety concerns directly to the responsible authority if needed.
5. Know Muster Stations
The muster list outlines crew responsibilities in emergencies like fire, collision, or abandon-ship scenarios. Identify your assigned muster station, understand your duties, and participate actively during drills.
6. Practice Good Housekeeping
Cleanliness in the engine room is essential not just for orderliness but also for early leak detection. Oil spills and clutter can lead to accidents. Always clean up after maintenance jobs and ensure pathways remain clear.
7. Learn Garbage Segregation Rules
Ships follow strict Waste Management Plans. Learn how to segregate garbage properly—plastics, metals, food waste, and oily rags go into color-coded bins. Proper waste handling ensures compliance with MARPOL regulations and keeps the marine environment safe.
8. Study Company Rules and Policies
Every shipping company operates under unique policies regarding safety, conduct, and environmental protection. Review these carefully. Understanding your employer’s policies helps avoid mistakes and maintain professional discipline onboard.
9. Learn How to Use Emergency Equipment
Your safety depends on knowing how to operate emergency tools. Learn how to use fire extinguishers, breathing apparatus, emergency generators, and life-saving appliances. Also know where they are stored and how to access them quickly.

10. Understand Lifeboat Launching Procedures
Different vessels use different lifeboat systems—freefall, davit, or on-load release mechanisms. Observe lifeboat drills and learn how to release, board, and operate them, including how to start the lifeboat’s engine during emergencies.
11. Learn Ship Alarms and Signals
Recognize the meaning of every alarm and signal onboard—fire alarm, general emergency alarm, or abandon ship signal. Quick recognition helps respond swiftly to emergencies and ensures coordinated action with your crew.
12. Read Manuals and Documentation
Technical manuals and checklists are your best friends. Study the operation and maintenance manuals of ship machinery—main engine, generators, purifiers, compressors, and boilers. This habit strengthens your understanding and helps you troubleshoot confidently.
13. Familiarize Yourself with Automation Systems
Modern ships rely heavily on automation in control rooms. Learn about sensors, alarms, and monitoring systems that control fuel flow, temperatures, and pressures. Understanding automation prevents operational errors and enhances your technical awareness.
14. Get Comfortable in the Engine Room
The engine room is where you’ll spend most of your time. Study its layout, equipment positioning, and operational flow. Familiarity with every section—purifier room, control room, and workshops—helps you move confidently and react swiftly during breakdowns or alarms.
15. Learn About Ship Maneuvering
Observe maneuvering operations carefully. During arrival, departure, or anchoring, understand how engineers coordinate with the bridge for propulsion control. Learn about main engine start/stop procedures, RPM control, and steering mechanisms.
16. Know About SOPEP
Shipboard Oil Pollution Emergency Plan (SOPEP) is mandatory under MARPOL. It guides crew members on handling oil spills, using containment kits, and reporting incidents. Familiarize yourself with the SOPEP locker and its contents.
17. Build Strong Working Relationships
Teamwork defines life at sea. Respect your seniors, communicate clearly, and assist peers during maintenance. Good relationships create a positive work culture, reduce stress, and promote learning.
Quick Checklist for New Junior Engineers
