Every Chief Engineer who has taken over a new vessel knows the feeling: you walk into an engine room full of equipment you have never seen configured quite this way before, with a departing engineer who has three days left on board and a Captain asking when you will be “up to speed.” The difference between a smooth transition and a dangerous one often comes down to a single document — the engine room familiarisation manual.
This is not a nice-to-have. It is a regulatory requirement under the ISM Code, and it is one of the first things a surveyor will ask to see during an audit.
The Regulatory Foundation
ISM Code Section 6: Resources and Personnel
Section 6.3 of the ISM Code (IMO Resolution A.741(18), as amended by MSC.353(92)) states:
“The Company should establish procedures to ensure that new personnel and personnel transferred to new assignments related to safety and protection of the environment are given proper familiarisation with their duties.”
This is deliberately broad. The IMO leaves the specifics to the Company and vessel, but the intent is clear: no one should be operating safety-critical equipment without documented familiarisation.
MCA Large Yacht Code (LY3)
For yachts subject to the MCA Large Yacht Code (MSN 1851 (M), as amended), LY3 Section 23 reinforces these requirements with specific attention to:
- Familiarisation with vessel-specific emergency procedures
- Location and operation of all fire-fighting equipment
- Operation of watertight doors and fire dampers
- Vessel-specific fuel and lubricating oil systems
What an Engine Room Familiarisation Manual Should Include
A well-structured manual serves two audiences: the new engineer who needs to learn the vessel, and the surveyor who needs to verify that familiarisation is happening systematically.
Essential Sections
| Section | Content | Why It Matters |
|---|---|---|
| Vessel particulars | Main dimensions, tonnage, classification details, flag state | Gives context for everything that follows |
| Main propulsion | Engine make/model, serial numbers, running hours, overhaul history | The engineer’s primary responsibility |
| Auxiliary engines | Same detail as main engines, including load-sharing configuration | Critical for power management |
| Fuel system | Tank arrangement, transfer procedures, purifier operation, fuel grades used | Survey focus area; MARPOL Annex VI compliance |
| Freshwater system | Watermaker operation, treatment, tank arrangement, testing schedule | Health and safety; MLC compliance |
| Bilge and ballast | System layout, oily water separator operation, MARPOL requirements | One of the most common PSC detention items |
| Fire-fighting systems | Fixed systems (CO2, water mist, foam), portable equipment locations | SOLAS Chapter II-2 compliance |
| Steering gear | Main and auxiliary systems, emergency procedures, testing requirements | SOLAS Chapter V, Regulation 26 |
| HVAC | System overview, refrigerant types and quantities, F-gas records | EU F-Gas Regulation compliance |
| Electrical distribution | Main switchboard, emergency generator, shore power changeover | Safety-critical knowledge |
| Alarms and monitoring | Alarm panel operation, alarm set points, override procedures | Watchkeeping competence |
| Emergency procedures | Vessel-specific responses to blackout, flooding, fire in engine room | ISM Code Section 8 |
The Often-Missed Items
From experience, the sections that most frequently get flagged during audits are:
- Alarm set points — Surveyors expect engineers to know the exact alarm and shutdown set points for main engines and generators. Your manual should list them.
- Valve identification — A valve location diagram specific to the vessel, not a generic system schematic. New engineers need to find the emergency fuel shut-off at 0300 in a smoke-filled space.
- Class and flag requirements — What special survey conditions or operational limitations apply to this specific vessel.
Structuring the Handover Process
A familiarisation manual is only useful if it is part of a structured handover process. Here is a framework that works well on superyachts.
The Three-Phase Handover
Phase 1: Pre-Arrival (Before the new engineer boards)
- Send the familiarisation manual digitally so the new engineer can review it in advance
- Provide a summary of any ongoing defects, pending class conditions, or upcoming maintenance
- Share the current planned maintenance schedule
Phase 2: On-Board Familiarisation (First 48-72 hours)
This is the critical period. Work through the manual systematically:
| Day | Focus Area | Sign-Off Required |
|---|---|---|
| Day 1 | Safety walk-through: emergency exits, fire stations, muster points, breathing apparatus locations, emergency stops | Both engineers + Master |
| Day 1 | Main propulsion systems: start/stop procedures, normal operating parameters, emergency procedures | Departing engineer |
| Day 2 | Auxiliary systems: generators, boilers, water treatment, sewage, OWS | Departing engineer |
| Day 2 | Deck machinery: stabilisers, bow thruster, anchor windlass, steering gear | Departing engineer |
| Day 3 | Administrative: PMS system, spare parts inventory, class certificates, oil record book procedures | Departing engineer |
Phase 3: Consolidation (First 2-4 weeks)
- New engineer works through operational checklists independently
- Identifies and documents any gaps in the familiarisation manual
- Reviews all outstanding work orders and planned maintenance
What Surveyors Actually Check
During ISM audits and annual flag state inspections, surveyors assess familiarisation in several ways:
Document Review
- Is there a familiarisation manual? Is it vessel-specific?
- Are there signed familiarisation records for all current engineering crew?
- Does the SMS include a procedure for familiarisation (not just the manual itself)?
Practical Assessment
Surveyors will often ask junior engineers direct questions to test whether familiarisation has actually occurred:
- “Show me how to start the emergency generator manually.”
- “Where is the emergency fuel oil shut-off valve?”
- “What is the procedure if the oily water separator alarm activates?”
- “What are the set points for the main engine high-temperature alarm and shutdown?”
If the engineer cannot answer confidently, the surveyor will raise a non-conformity against the familiarisation process — not against the individual.
Common Deficiencies Found During Audits
| Deficiency | ISM Code Reference | Severity |
|---|---|---|
| No familiarisation records on file | Section 6.3 | Major non-conformity |
| Generic manual not reflecting vessel systems | Section 6.3 / 6.5 | Non-conformity |
| No evidence of familiarisation for crew who joined within last 6 months | Section 6.3 | Non-conformity |
| Familiarisation manual not reviewed or updated after system modifications | Section 6.4 | Observation |
| No Master’s sign-off on safety familiarisation | Section 6.2 | Non-conformity |
Maintaining the Manual
A familiarisation manual is not a one-time document. It needs active maintenance:
- After every refit or system modification: Update affected sections, add new equipment details, revise diagrams.
- Annually: Review the entire document for accuracy, even if no major changes have occurred. Date and sign the review.
- After every audit finding: If a surveyor identifies a gap, update the manual and the familiarisation process immediately.
Under ISM Code Section 6.4, the Company must ensure that all personnel involved in the SMS have “an adequate understanding of relevant rules, regulations, codes, and guidelines.” Your familiarisation manual is the primary evidence that this requirement is being met at the vessel level.
The Practical Reality
On a superyacht, crew turnover is a constant reality. Engineers move between vessels frequently, and each vessel has its own quirks — the generator that needs a specific starting sequence, the fire damper that sticks, the bilge alarm sensor that reads high when the vessel heels to starboard.
A good familiarisation manual captures this institutional knowledge. It transforms what would otherwise be tribal knowledge passed on verbally (or not at all) into a documented, auditable system. When done properly, it does not just satisfy the surveyor — it keeps people safe and protects the vessel.
The investment of time in creating and maintaining a proper engine room familiarisation manual pays for itself the first time a new engineer has to respond to an emergency at 0200 on a vessel they have only been aboard for a week.
