🧭 Navigation Systems
4 topicsDual Compass Setup
- Gyro Compass: Points to True North — primary navigational compass.
- Magnetic Compass: Points to Magnetic North — backup system. Affected by ship's steel structure, wiring, and magnetic induction.
Gyro Compass — Working Principle (3-Stage Pendulous Loop)
Gyro Error Causes
- Speed Error: Vessel's own speed causes the gyro to sense a false rotation.
- Latitude Error: Gyro settles slightly east/west of true meridian at high latitudes.
- Ballistic Deflection: Sudden course or speed changes disturb the pendulous system temporarily.
"Explain the working principle of a gyro compass." — Focus on the three-stage loop: inertia → precession → pendulous correction. He may follow with: "What are the errors of a gyro compass?" — Know speed error, latitude error, and ballistic deflection. As CE you are responsible for maintaining gyro accuracy records in the Movement Book.
Purpose & Applicability
- Purpose: Globally identifies and tracks ships for safety, security, SAR, and coastal state awareness.
- Applicability: All ships 300 GT and above — SOLAS Chapter V, Regulation 19-1.
- Transmission: Every 6 hours automatically via existing satellite communication equipment.
- Master's authority: Can switch off transmission under exceptional circumstances (e.g., drydock).
Data Package Transmitted (3 elements)
- Ship Identity: IMO number, name, MMSI, call sign.
- Position: Latitude and longitude.
- UTC date and time of position fix.
LRIT Network Architecture
"What is LRIT and what data does it transmit?" — Know all 3 data elements, the 6-hour interval, and the 300 GT threshold. He may chain this with: "What is the difference between AIS and LRIT?" — See the next card. Key distinction: LRIT is closed-loop / secure; AIS is open broadcast.
| Parameter | AIS | LRIT |
|---|---|---|
| Primary purpose | Collision avoidance / local navigation | International safety, security & SAR |
| Network type | Open loop — public broadcast | Closed loop — secure, official DCs only |
| Medium | VHF radio (terrestrial) | Satellite communication |
| Range | 20–30 NM (line of sight) | Worldwide coverage |
| Frequencies | 161.975 MHz (AIS 1) / 162.025 MHz (AIS 2) | No fixed channels — encrypted satellite |
| Access | Anyone with receiver can read | Flag / coastal / port states only |
"What is the difference between AIS and LRIT?" — The open vs closed loop distinction is the key answer. AIS is for local collision avoidance and is publicly visible; LRIT is for long-range state-level tracking with restricted access. Both are mandatory under SOLAS V but serve entirely different purposes.
MMSI — Maritime Mobile Service Identity
- Format: Unique 9-digit number issued by Flag State.
- Structure: First 3 digits = MID (Maritime Identification Digits, allocated by ITU) + 6 unique digits for the vessel.
- Flag change rule: MMSI must change if the vessel changes Flag State — it is country-specific.
- Integration: Hard-programmed into DSC radio equipment, HF/VHF consoles, and AIS transponder.
Three Ship Identifiers Compared
| Identifier | Purpose | Changes? |
|---|---|---|
| Call Sign | Voice communication over VHF/HF — overcomes language barriers | Changes with flag state |
| IMO Number | Fixed 7-digit permanent identifier — never changes regardless of flag or name | Never changes |
| Official Number | Administrative/legal tracking in Official Log Book | Country-specific |
"What is MMSI and when must it change?" — Must change on flag change because the MID (first 3 digits) identifies the nation. Follow-up: "What never changes?" — The IMO number — it is permanently assigned at build and survives all flag, name, and ownership changes.
⚖ Stability & Structure
5 topics9 Mandatory Sections
- General description of the ship.
- Instructions on how to use the booklet.
- General Arrangement plan — watertight compartments, vents, air pipes.
- Capacity plan — tank volumes, centres of gravity, free surface effect data.
- Tank sounding and ullage tables.
- Hydrostatic curves and cross curves of stability (GZ curves).
- Descriptions of standard stability calculations and worked examples.
- Inclining experiment list and formal report data.
- Loading restrictions — maximum allowable KG limits, permissible draughts.
"What are the contents of the stability booklet?" — List all 9. He may follow with: "When is the stability booklet updated?" — After structural alterations, cargo modifications, or at the periodical inclining experiment (typically every 5 years or after major conversion). The booklet must be approved by the Administration or recognised organisation.
Key Principles
- Both GT and NT are dimensionless indices — not physical volumes in cubic metres, despite being derived from volume.
- GT = total enclosed volume of all spaces on the ship (including non-cargo).
- NT = volume of cargo-carrying spaces only — represents earning capacity.
- Measured and verified by a Classification Society surveyor; issued as the International Tonnage Certificate.
K₁ = 0.2 + 0.02 × log₁₀(V) | V = total enclosed volume (m³)
NT = K₂ × Vc × (4d/3D)² + K₃ × [(N₁ + N₂)/10]
Vc = cargo space volume | K₂ = 0.2 + 0.02 × log₁₀(Vc)
d = moulded draught | D = moulded depth | N₁/N₂ = passenger numbers
Applied Uses
- GT determines: Manning levels, SOLAS/MARPOL applicability thresholds, convention requirements, safety regulations.
- NT determines: Port dues, canal fees (Suez, Panama), pilotage charges, tonnage taxes.
"What is the difference between GT and NT?" — GT covers all enclosed spaces; NT covers only cargo spaces. He may ask: "Why does the Suez Canal use NT?" — Because NT reflects actual earning capacity and cargo-carrying use of the canal. SOLAS thresholds use GT because they reflect the overall size and complexity of the vessel.
Definition
The maximum weight a ship can safely carry when loaded to its maximum permissible summer load line. Does not include the lightship (empty vessel) weight.
Regulatory Significance
- CII calculation: DWT is the denominator in the AER formula — CO₂ ÷ (DWT × distance). Low DWT → higher CII (worse rating).
- EEDI/EEXI: DWT used as the capacity parameter for cargo ships in EEDI formula.
- MARPOL Annex I: ORB retention limits referenced against ship's DWT for some vessels.
"What is DWT?" — Define it as the maximum carrying capacity at summer load line. He may chain this to: "How does DWT affect CII?" — DWT is the denominator in AER; a larger DWT with the same fuel consumption gives a better (lower) CII. This is why running in ballast degrades CII — less transport work for same fuel burn.
Maximum lowest opening gap (from deck): 230 mm
Maximum intermediate rail spacing: 380 mm
Design Justification
- 230 mm lowest gap — prevents an adult's torso from passing through, stops MOB incidents.
- 380 mm intermediate spacing — prevents leg entrapment and falling through gaps.
- Where fitted as open rails (no bulwark), all three dimensions must be met.
"What are the dimensions of guardrails?" — Quote all three: 1,000 mm height, 230 mm lowest gap, 380 mm intermediate spacing. He may follow with: "Under which convention?" — Load Lines Convention (ILLC), Annex II. On container vessels these are critical on hatch covers and weather decks during lashing operations.
Definition
Girding occurs when a vessel pulls a connected tugboat beam-on (perpendicular) to its heading via the towline, creating a capsizing force on the tug. The tug is unable to manoeuvre out of the perpendicular position and is overwhelmed by the lateral pull.
4 Key Influencing Factors
- Suitability of the tug: Size, power, and hull manoeuvrability.
- Towline length: Longer scope alters the stability dynamics — shorter lines increase risk.
- Towing point location: Low towing point reduces girding risk; high point increases it.
- Environmental conditions: Wind, tidal streams, and currents amplify the perpendicular force.
"What is tug girding?" — Define the perpendicular pull mechanism and state all 4 factors. Relevant on container vessels when berthing/unberthing with tugs in ports like Singapore, Rotterdam, or during offshore operations. As CE, awareness of tug operations is expected at management level.
🔧 Machinery & Materials
2 topicsDefinition
Embrittlement: Loss of ductility in a material, making it brittle and prone to sudden fracture.
Caustic Embrittlement: A specific type of stress corrosion cracking caused by exposure of steel to concentrated Sodium Hydroxide (NaOH) under high temperature and stress — targets boiler bends, joints, and welds.
Chemical Accumulation Cycle in Boilers
Prevention: Strict pH control + phosphate treatment to neutralise localised caustic pockets
"What is caustic embrittlement?" — He expects the chemical mechanism: Na₂CO₃ → hydrolysis → NaOH → concentration at cracks → electrochemical cell → metal loss. Quote the boiler pH range: 8.5 to 10.5. He may also ask about the difference between caustic embrittlement and hydrogen embrittlement — different mechanism, same result (brittleness).
What it is
A mandatory statutory document approved by the Administration and prepared by the engine manufacturer. Required to maintain the engine's EIAPP (Engine International Air Pollution Prevention) Certificate under MARPOL Annex VI Regulation 13.
Contents (8 elements)
- Identification of all components, settings, and parameters that alter NOₓ emission profile.
- Full specifications for replacement parts affecting emissions.
- Allowable adjustment ranges for engine settings and timing sequences.
- Documentation for any emission-reduction equipment or exhaust after-treatment systems.
- Initial test performance data — rated power, engine speed parameters.
- Certified copy of the original parent engine test record data sheet.
- Documented operating restrictions or limitations on the parent engine.
- Approved onboard verification methodologies for Port State and Flag State surveys.
"What is the NOₓ Technical File and what does it contain?" — This is a Simon Sir favourite — he focuses on air pollution prevention. Know it is engine-specific, manufacturer-prepared, Administration-approved. During a PSC inspection, surveyor checks that onboard engine settings match the Technical File parameters. Any deviation = non-conformance.
🌍 GHG & Environmental
6 topicsApplicability & Function
- Applies to: Ships 5,000 GT and above on international voyages — from January 2023.
- Function: Measures annual operational efficiency — CO₂ emitted per unit of transport work.
- Rating scale: A (superior) → B (minor superior) → C (moderate) → D (minor inferior) → E (major inferior).
Required CII = (1 − Z/100) × CII Reference Baseline
Z = annual reduction factor (tightens each year toward 2030 targets)
Enforcement — Corrective Action Plan
Rated E for any single year → CAP required immediately
CAP must show pathway to C or better; must be approved by Administration
"What is CII and how is it calculated?" — Know the AER formula, the A–E rating system, and when a CAP is triggered (D×3 or E×1). He will likely follow: "What can you do operationally to improve CII on your vessel?" — Slow steaming, fuel optimisation, trim optimisation, cargo planning, route planning, shore power in port.
Persistent Oil
High-viscosity oils that do not evaporate or naturally degrade in water — remain in the environment for extended periods requiring active physical response. Examples: HFO, crude oil, heavy diesel.
Non-Persistent Oil — Classification Criteria
2. At least 95% of volume must distil at 370°C
Examples: Petrol, kerosene, light diesel
Significance for Spill Response
- Persistent spill: Requires booms, skimmers, dispersants — long-term response operation.
- Non-persistent spill: Evaporates relatively quickly — reduced long-term environmental impact but immediate fire/explosion risk.
"What is the difference between persistent and non-persistent oil?" — Quote the distillation criteria: 50% at 340°C and 95% at 370°C. He may link to SOPEP and MARPOL Annex I obligations. HFO carried on your container vessel is persistent — important for your Shipboard Oil Pollution Emergency Plan.
4 Mandatory Compliance Documents
- IBWMC — International Ballast Water Management Certificate — issued by Flag State / RO.
- BWMP — Ballast Water Management Plan — approved, ship-specific, describes the management method.
- BWRB — Ballast Water Record Book — records every ballast uptake, exchange, and discharge operation.
- Type Approval Certificate — confirms the onboard BWTS (Ballast Water Treatment System) meets IMO G8 or USCG standards.
Standards — D-1 vs D-2
- D-1 (Exchange Standard): Exchange ballast water at >200 NM from land, >200 m depth. 95% volumetric exchange. Transitional measure — being phased out.
- D-2 (Performance Standard): Treatment standard — specific limits on viable organisms per m³. Required for all new ships and retrofits.
"What documents are required for ballast water management?" — List all 4. He may ask about D-1 vs D-2 standards. Note: USCG has stricter requirements than IMO D-2 for ships entering US waters — relevant on container vessels calling US East Coast.
Regulation
- Effective: July 1, 2024 — ban on both carriage and use of HFO in Arctic waters.
- Exemption: Vessels flying flags of Arctic coastal states — extension to January 1, 2029.
- Regulation: MARPOL Annex I, Regulation 43A.
4 Environmental & Socio-Economic Drivers
- Black Carbon / Albedo Effect: HFO combustion produces black carbon soot. Deposited on Arctic ice → darkens surface → reduces sunlight reflection → accelerates ice melt and sea-level rise.
- Extreme Spill Persistence: HFO's high viscosity means spills form heavy tar clumps — virtually irrecoverable in freezing Arctic waters.
- Challenging Response: Geographic remoteness, absence of infrastructure, and harsh conditions make spill response almost impossible.
- Indigenous Livelihoods: Arctic communities depend entirely on clean waters for fishing and food security.
"Why was the Arctic HFO ban introduced?" — Quote all 4 reasons. Know the date: July 1, 2024. He may link this to the Polar Code (SOLAS/MARPOL mandatory from 2017) and ask whether your vessel trades Arctic — on container vessels, less common, but the regulatory awareness is tested.
Carbon Credits
- Origin: Introduced under the Kyoto Protocol, 1997.
- Definition: A legal permit allowing emission of 1 metric tonne of CO₂ equivalent (tCO₂e).
- 1 carbon credit = 1 tCO₂e reduced, removed, or avoided.
Cap and Trade System (EU ETS)
- Regulator sets a cap on total emissions across an industry.
- Entities reducing below their cap → sell surplus credits on the open market.
- Entities exceeding their cap → buy credits to cover the deficit or face penalties.
- Maritime EU ETS: From January 2024 — ships ≥5,000 GT calling EU ports must surrender allowances for 40% of emissions (2024), rising to 70% (2025) and 100% (2026).
"What is a carbon credit?" — 1 credit = 1 tCO₂e. He may then ask about EU ETS and its applicability to shipping from 2024. On Maersk container vessels calling EU ports, you are directly affected — EU ETS compliance is live. Know the phase-in: 40% (2024) → 70% (2025) → 100% (2026).
Carbon Footprint
Total GHG generated by an individual, vessel, or corporation — measured in CO₂ equivalent (CO₂e).
GWP — Global Warming Potential
Comparative index measuring how much heat a GHG traps over 100 years relative to CO₂ (baseline = 1).
| Greenhouse Gas | GWP (100-year) |
|---|---|
| CO₂ | 1 |
| CH₄ (Methane) | 27–30 |
| N₂O (Nitrous Oxide) | 273 |
| HFCs | 100–10,000 |
| SF₆ (Sulfur Hexafluoride) | 25,200 |
Ammonia (NH₃) as Marine Fuel — The Trade-off
- GWP = 0 | ODP = 0 — excellent decarbonisation credentials.
- Risk: Combustion can produce N₂O (GWP = 273) — if not managed, partially offsets the environmental benefit.
- Also: highly toxic and corrosive — major safety risk in enclosed spaces.
"What is GWP?" — Define it and quote at least: CH₄ = 27–30, N₂O = 273, SF₆ = 25,200. He may ask: "Why is LNG not truly green?" — Methane slip (unburned CH₄, GWP 27–30) escaping to atmosphere can negate CO₂ benefits. This is the methane slip problem — a key GHG oral topic.
⚓ Commercial & Legal
6 topics| Parameter | CLC 1969 | CLC 1992 Protocol |
|---|---|---|
| Geographical scope | Territorial Sea only | Extended to EEZ |
| Vessel coverage | Laden tankers only | Ballast tankers + combination carriers with oil residues |
| Preventive measures | Claims after spill only | Covers preventive actions before spill occurs |
| Liability limit | Lower scale | Max 89.77 million SDR |
"What is the difference between CLC 1969 and 1992?" — The 4 key improvements in 1992: EEZ coverage, ballast tanker coverage, preventive measures, and higher liability cap (89.77 million SDR). Link to: "What is the P&I Club's role?" — P&I insurance covers CLC liabilities. Blue Card = Certificate of Financial Responsibility.
| Parameter | In Rem | In Personam |
|---|---|---|
| Target | Against the physical property — the ship (the res) | Against a specific person or legal entity |
| Relationship needed? | No personal relationship required | Personal or contractual link required |
| Right scope | General right — enforceable against the whole world | Contractual right — enforceable only against named party |
| Transferability | Right follows the property through ownership changes | Cannot be transferred to another party |
| Example | Ship arrest for unpaid salvage / maritime lien | Breach of contract, personal debt |
"What is an action in rem?" — Action against the ship itself, regardless of who owns it. The classic maritime example is a ship arrest for unpaid salvage or crew wages. Key principle: the lien attaches to the ship and travels with it through ownership changes — that's why it is "against the world."
Definition

"What is a CBA and what does it contain?" — List the 7 elements. He may ask: "Can a CBA override MLC minimums?" — Only in the seafarer's favour — a CBA can provide better terms than MLC but never worse. The ITF (International Transport Workers' Federation) is the key union body monitoring CBAs.
Cabotage — Definition
Legal framework restricting domestic maritime cargo/passenger transport between ports of the same nation to vessels flying that nation's flag.
Indian Cabotage Framework
- Pre-2018: Only Indian-flagged or Indian-chartered vessels could engage in coastal trade.
- 2018 Relaxation: Foreign ships permitted to move transshipment containers between Indian hubs (EXIM) and transport specific domestic commodities (agricultural cargo, fish, horticulture, fertilisers).
DGS Trading Licences (3 types)
- GTL — General Trading Licence: Indian-flagged vessels — unlimited coastal + international trade. Validity: 10 years.
- CTL — Coastal Trading Licence: Domestic vessels restricted to coastal trade routes only.
- SPL — Specific Period Licence: Temporary licence granted to foreign-flagged vessels for defined coastal operations.
"What is cabotage?" — Define it, then explain the Indian context including the 2018 relaxation for transshipment containers. Know the 3 DGS licence types. As a seafarer on a Maersk vessel, your ship may call Indian ports — knowledge of coastal trade restrictions is relevant at CE level.
ROFR — Right of First Refusal
A protectionist procurement mechanism: when Indian government agencies or PSUs issue open tenders for shipping services, a qualified Indian-flagged bidder is given the first opportunity to match the lowest foreign bid. If matched, the contract goes to the Indian operator; only if declined does it go to the foreign vessel.
Duties of a Shipping Master (6 statutory duties)
- Verification and issuance of the Continuous Discharge Certificate (CDC).
- Supervision of sign-on and sign-off of officers, engineers, and ratings.
- Review port clearance applications — issue inward and outward clearances.
- Legal custodian of personal effects, documents, and wages of deceased/hospitalised seafarers (Section 132).
- Hear and arbitrate disputes between Master, Owner, Port Agent, and crew.
- Facilitate and regulate formal contracts for sea service apprenticeships.
"What are the duties of a Shipping Master?" — List all 6. He may ask: "Who issues the CDC?" — The Shipping Master (DG Shipping delegated authority). Know that the Shipping Master is a statutory officer under the Merchant Shipping Act 1958 — different from the Ship's Master.
Force Majeure
- Definition: Unforeseeable events completely beyond the control of contracting parties, making performance physically or legally impossible.
- Standard triggers: Acts of God (natural disasters), war, strikes, pandemics, terrorism.
- Legal effect: Affected party is shielded from liability for contractual failure.
Maritime Torts — 3 Categories
- Intentional Torts: Wilful acts designed to cause harm — e.g., defamation, trespass.
- Negligence Torts: Failure to exercise reasonable care causing accidental harm — e.g., navigator's failure causing collision.
- Strict Liability: Automatic liability regardless of fault — e.g., oil spill under CLC (shipowner liable even without negligence), defective equipment causing injury.
"What is Force Majeure?" — Define it and list standard triggers. He may follow: "What is the difference between a tort and a breach of contract?" — Tort is a civil wrong independent of contract; breach is failure of a contractual obligation. In maritime law, oil spill liability under CLC is a strict liability tort — the shipowner is liable even without negligence.
📋 Management Systems & Organisations
6 topicsCondition of Class (CoC)
- Issued for structural defects, mechanical damage, or issues with class-item machinery.
- Not immediately severe enough to suspend class — but carries a strict remedial deadline.
- Consequence of non-compliance: Certificate of Class is invalidated → ship becomes unseaworthy.
Memorandum of Class (MoC)
- Non-critical observations — do not affect class status or require immediate action.
- Serves to maintain owner/operator awareness of minor deviations, exemptions, or limitations.
- Common contexts: minor design deviations, survey exemptions, operating limitations.
Anniversary Date
The specific calendar day and month of each year corresponding to the expiry date of a major statutory certificate. Annual surveys must be completed within 3 months before or after the anniversary date.
"What is a Condition of Class?" — It is a formal directive from the Classification Society with a time-bound remedial requirement. He may ask: "What happens if you don't clear a CoC?" — Class is suspended → vessel is unseaworthy → trading prohibited. As CE you own the technical resolution of all CoC items.
