🔒 Maritime Security
3 topicsUKMTO — United Kingdom Maritime Trade Operations
- HQ: Dubai — primary liaison for Indian Ocean, Red Sea, Gulf of Aden, Arabian Sea.
- Role: Direct operational link between merchant vessels and military naval forces in the region.
- VRS (Voluntary Reporting Scheme): Vessels in High Risk Areas (HRA) are strongly encouraged to report position and suspicious activity. Not mandatory — but highly recommended by BMP5.
MSCHOA — Maritime Security Centre Horn of Africa
- Established by: EUNAVFOR (EU Naval Force) — combats piracy in Gulf of Aden and Indian Ocean.
- Monitoring: 24/7 surveillance — Western Indian Ocean, Gulf of Aden, Somali Basin.
- Functions: Intelligence collection & analysis; coordination with international naval forces; voluntary ship registration via MSCHOA website.
- Collaboration: Operates jointly with UKMTO, EUNAVFOR, and regional naval coalitions.
"What is the difference between UKMTO and MSCHOA?" — Know that UKMTO is operational liaison (Dubai-based, military coordination), while MSCHOA is intelligence and monitoring (EUNAVFOR, vessel registration). Both are referenced in BMP5 (Best Management Practices 5) which Simon Sir may ask about in context of piracy.
UNCLOS — Key Articles on Seaworthiness
- Article 91: Flag State duties — a ship must sail under only one flag; the flag state exercises jurisdiction and control over the ship in administrative, technical, and social matters.
- Article 94: Duties of the Flag State — must ensure ships flying its flag comply with international regulations on safety of life at sea, prevention of collision, manning, and prevention of pollution.
- Article 219: Enforcement measures — Port States may direct a vessel to the nearest appropriate repair yard if unseaworthy and likely to cause marine pollution.
"What does UNCLOS say about seaworthiness?" — He expects you to connect Flag State responsibility (Art. 94) with Port State enforcement (Art. 219). Note that Art. 91 is about nationality/flag, not seaworthiness per se.
A vessel is legally unseaworthy if any of the following apply
- Structural Faults: Material construction or design fails to comply with statutory regulations.
- Substandard Crewing: Master or crew unqualified, or numbers below Minimum Safe Manning Certificate.
- Missing Certificates: Any legally mandated statutory certificate is absent or expired.
- Deficient Equipment: Required machinery, safety equipment, or materials are missing.
- Mechanical Failure: Main machinery or auxiliaries unfit for the intended voyage.
- Improper Stowage: Cargo or ballast stowage that jeopardises safe conduct of the voyage.
"If you found the ship was unseaworthy — what would you do as CE?" — Frame your answer around ISM Code Clause 5 (Master's overriding authority), SOLAS I/14 (maintenance of conditions after survey), and reporting through the DPA. Do not say "sail and fix later."
⚖ Stability & Cargo
2 topicsDefinition & Functions
A type-approved software system used to determine structural impacts of loading and ballasting on ship stability. Key outputs: shear force, bending moment, GM, and stress limits — calculated before departure.
Key Rules
- All ship-specific stability data must be pre-loaded.
- Must be type-approved by the Flag State Administration or recognised Classification Society.
- Critical proviso: Serves as a calculation aid only — never a substitute for the approved Stability Booklet.
"What is a Loadicator and what are its limitations?" — Always state that it is not a replacement for the stability booklet. The approved booklet holds legal authority; the loadicator is a tool. Also mention type approval requirement.
Freeboard — Definition
The vertical distance measured amidships from the upper edge of the deck line to the upper edge of the applicable load line mark.
Permanently marked amidships on each side of the ship.
Significance
- Freeboard is the primary safety reserve — it limits how deep a ship can be loaded.
- Minimum freeboard is assigned by the Classification Society / Flag State per Load Lines Convention 1966 (LL 66) and Protocol 1988.
- Tabular freeboard is assigned per ship type and length, then adjusted for block coefficient, depth correction, sheer, and superstructure deductions.
"What is freeboard and why is it important?" — Link it to reserve buoyancy. He may then ask about the different load line zones (tropical, summer, winter, winter North Atlantic) or how freeboard varies for timber vessels.
🌍 Environmental & GHG
5 topicsPDMS — Polydimethylsiloxane
- Application: Silicone oil integrated into a matrix and applied as a foul-release coating on the underwater hull.
- Working Principle: Hydrophobic + lubricating properties lower the hull's coefficient of friction — marine organisms cannot adhere to the surface.
- Environmental Advantage: Non-toxic, entirely mechanical action — an eco-friendly alternative to biocidal anti-fouling paints (which are regulated under the AFS Convention 2001).
PSSA — Particularly Sensitive Sea Area
- Definition: An area designated by IMO requiring special protection from shipping activity due to ecological, socio-economic, or scientific significance.
- Designation Criteria: (1) Ecological significance — rare/unique ecosystems; (2) Socio-economic value — tourism, fisheries, trade; (3) Scientific/historical importance.
- Examples: Great Barrier Reef, Baltic Sea, NW Mediterranean, Torres Strait.
- Associated Protective Measures (APMs): May include routing measures, speed restrictions, discharge prohibitions, or mandatory pilotage.
"What is a PSSA and what measures apply?" — Know the three designation criteria and that the protective measures are separate IMO instruments approved alongside the PSSA designation. Do not confuse PSSA with ECA (Emission Control Area).
Carbon Factor (CF) — Definition
The mass of CO₂ emitted per unit mass of fuel burned. Derived from atomic masses of carbon and oxygen in the CO₂ molecule.
Mass Ratio = 44 ÷ 12 = 3.67
For fuel with 85% carbon (MDO): 3.67 × 0.85 ≈ 3.12
Standard CF Values (MARPOL Annex VI, Reg 27)
- HFO: 3.114 t CO₂ / t fuel
- MDO / MGO: 3.206 t CO₂ / t fuel
- LNG (Methane): 2.750 t CO₂ / t fuel
- LPG: 3.030 t CO₂ / t fuel
- Methanol: 1.375 t CO₂ / t fuel
- Ammonia: 0 t CO₂ / t fuel (zero-carbon fuel)
Total: 63 t/day × 3.114 = 196.18 t CO₂/day
"What is CF and how do you calculate CO₂ emissions?" — Know the formula, know the values for HFO and MGO from memory, and be able to do the multiplication. He may also ask how CF feeds into CII calculation (CO₂ ÷ transport work).
International Energy Efficiency Certificate (IEEC) — Chapter 4 Regulations
- Reg 22 (EEDI Technical File): Attained EEDI — applicable to new ships from 2013 based on build phase.
- Reg 23 (EEXI Technical File): Attained EEXI + EEXI OMM Manual — applicable from January 2023 to existing ships ≥400 GT.
- Reg 24 & 25: Required EEDI / EEXI structural limits by ship type and size.
- Reg 26 (SEEMP): Ship Energy Efficiency Management Plan — Part I (2013), Part II for DCS (2019), Part III for CII (2023). SoC required for Parts II & III.
- Reg 27 (IMO DCS): Data Collection System — fuel oil consumption reporting from 2019.
- Reg 28 (CII): Carbon Intensity Indicator rating — from January 2023.
International Air Pollution Prevention Certificate (IAPP) — Regulations
- Reg 12 (ODS): Ozone Depleting Substances — ODS Record Book.
- Reg 13 (NOₓ): NOₓ Technical File, EIAPP Certificate, Parameters Checklist.
- Reg 14 (SOₓ): BDN, fuel oil sampling, fuel changeover log. Global cap: 0.50% S (from 2020); ECA: 0.10% S.
- Reg 15 (VOC): VOC management plan for tankers.
- Reg 16 (Incineration): Incinerator type approval and operations.
"What regulations are covered under MARPOL Annex VI and which certificates do they generate?" — The IEEC and IAPP are the two key certificates. Know which regulation number maps to which requirement. Reg 26 (SEEMP), Reg 27 (DCS), Reg 28 (CII) are the GHG trio Simon Sir focuses on.
IMO DCS — Data Collection System (Reg 27)
- Applicability: Ships of 5,000 GT and above on international voyages.
- Incorporated in: SEEMP Part II (Data Collection Plan).
- Approved methodologies: (1) Flow meter; (2) Tank sounding/monitoring; (3) BDN method.
Primary GHGs in Shipping (per IMO GHG Strategy)
- CO₂, CH₄ (methane), N₂O (nitrous oxide), HFCs, PFCs, SF₆, NF₃
- Note: NOₓ is an air pollutant (Reg 13) but also has climate effects — do not confuse with the GHG list above.
"What is IMO DCS and how does the reporting work?" — Know the three fuel measurement methods and the 31 March → 31 May → 30 June timeline. Data privacy: vessel data is anonymised when submitted to GISIS.
IMO 2023 GHG Strategy — Key Targets
- Net-Zero GHG emissions from international shipping: by or around 2050.
- Indicative checkpoints: 20–30% reduction by 2030 and 70–80% reduction by 2040 (vs 2008 baseline).
- Mid-term measures: adoption expected 2025, effective mid-2027.
Two Pillars of Mid-Term Measures
- Technical Element: Goal-based marine fuel standard — phased reduction of GHG intensity of marine fuels (FuelEU approach).
- Economic Element: GHG pricing/carbon levy mechanism — mandatory financial contribution per tonne of fuel consumed.
Proposed Economic Schemes
- ZESIS (Japan) — Zero Emission Initiative, feebate model.
- IMSF&R (Argentina) — International Maritime Sustainability Funding & Reward.
- GHGL (Marshall & Solomon Islands) — GHG Levy.
- IMO Net-Zero Framework — GHG levy of ~$150/tonne CO₂eq under discussion (MEPC 83, 2025).
"What are the IMO GHG targets for 2050?" — Quote net-zero by or around 2050, checkpoints 2030 and 2040, and the two pillars: technical (fuel standard) and economic (pricing). He may push on "what is the difference between EEXI, CII and the 2050 strategy?"
🧭 STCW & Manning
8 topicsCore Document
The Minimum Safe Manning Document (MSMD) — issued by the Flag State Administration under SOLAS V/14 and IMO Resolution A.1047(27).
Determining Factors (8 Criteria)
- Ship particulars — size and type.
- Number, size, and type of main propulsion machinery and auxiliaries.
- Level of vessel automation (UMS operations).
- Nature of cargo carried.
- Number and frequency of port calls.
- Requirements of the Ship Security Plan (SSP).
- Designated trading areas.
- Prescribed grades and numbers of officers and ratings.
"What factors determine minimum safe manning?" — List all 8 criteria. He may ask: "Can the CE override the minimum manning document?" — No, but the Master has overriding authority under ISM Code Cl. 5 to not sail if he believes it is unsafe.
Core Definitions
- Hazard: A physical condition or situation with potential to cause injury, property damage, or environmental harm.
- Risk: The likelihood/frequency of a hazardous event occurring within a defined timeframe or circumstance.
(2) Consequence and severity of the event
(3) Frequency / probability of harm occurring
"What is the difference between hazard and risk?" — Classic Simon Sir opener. Then he links it to risk assessment in ISM Code (Cl. 7 — shipboard operations) and may ask for examples onboard a container vessel. Connect to PTW, toolbox talks, and HIRA.
COC — Certificate of Competency
- Issued to: Masters, Officers (Deck & Engine), GMDSS Radio Operators — STCW Chapters II, III, IV.
- Issuing authority: National Maritime Administration only (in India: DG Shipping).
- Granted after verification of training evidence, sea service, and examination.
COP — Certificate of Proficiency
- A credential other than COC — verifies meeting specific STCW training or competency standards.
- Examples: BST (EFA, FPFF, PSSR), PSCRB, STSDSD, Advanced Fire Fighting, Medical First Aid, ECDIS, tanker training COPs.
- Issued by approved Maritime Training Institutes (MTIs) or the Administration.
"What is the difference between COC and COP?" — Key distinction: COC is issued only by the Administration, while COP can be issued by approved training institutes. He may then ask "which certificate do you hold?" — always know your own COC rank and endorsements.
Entry into Force: 1 January 2012
7 Major Changes
- Fraud Prevention: Online verification systems (Master Checker) to combat fraudulent certificates.
- ETO (Electro-Technical Officer): Introduced as a mandatory COC rank for the first time.

- Rest & Fitness: Revised hours of rest; strict drug and alcohol abuse prevention guidelines.
- Specialised Training: Polar operations and Dynamic Positioning (DP) mandatory training criteria introduced.
"What were the key changes in the 2010 Manila Amendments?" — He expects at least 5 points. The ETO introduction and fraud prevention are the two most distinctive changes. Mention the transition period: certificates had to be revalidated to Manila standard by 1 January 2017.
VICT — Vertical Integration Course for Trainers
- Formerly known as: TOTA (Training for Trainers and Assessors).
- Based on: IMO Model Course 6.09 | Compliant with STCW Reg I/6.
- Duration: 10 days (60 instructional hours).
- Purpose: Mandatory for mariners seeking to qualify as certified instructors for DG Shipping-approved courses at Maritime Training Institutes (MTIs).

- Part B — Chapter III: Engine Department — pre-sea courses, MEO Class I syllabus, simulator requirements.
"What is the TEAP manual?" — He may ask this to assess whether you know the regulatory framework governing your own oral examination. Key point: it replaced META, it is published by DG Shipping, and it is aligned with STCW and IMO Model Courses.
Standard Rest Hour Limits (STCW Ch. VIII)
Minimum rest in any 7-day period: 77 hours
Max split: 2 periods, longest ≥ 6 continuous hours
Max interval between rest periods: 14 hours
Emergency Exceptions (Master's Authority)
Master may suspend rest requirements for: (1) immediate safety of the ship; (2) protection of cargo; (3) assisting ships/persons in distress. Compensatory rest must be provided afterwards.

- Company/SMS policy: Typically 0.00% BAC — avoid alcohol at least 4 hours before watch.
"What are the rest hour requirements?" — Know 10 hrs / 24 hrs and 77 hrs / 7 days cold. He will follow with: "Can the Master override rest hours?" — Yes, but only in the 3 emergencies listed, and compensatory rest must be given. Relaxation is different from emergency override.
7 Principles of Watchkeeping (STCW Reg VIII/2)
- Proper arrangement — assign watchkeepers per situation.
- Qualification & fitness — physically and mentally fit.
- Defined roles — clear individual/team responsibilities.
- Efficient resource management — personnel, equipment, information.

- Management Level: Chief Engineer / Second Engineer — STCW Table A-III/2.
"What are the principles of watchkeeping?" — He expects all 7 STCW principles. Then: "At what STCW level are you operating?" — As 2/E: management level (Table A-III/2). As a CE candidate, you must know both operational and management competency tables.
📚 Training & Education Concepts
2 topics3 Learning Domains
- Cognitive Domain: Knowledge-based learning — most widely applied in maritime training.
- Affective Domain: Attitude and values-based learning.
- Psychomotor Domain: Physical skill and motor coordination-based learning.
6 Cognitive Levels — Lower → Higher Order
→ 4. Analyzing → 5. Evaluating → 6. Creating
Updated in 2001 to focus on thinking processes and knowledge application. Original taxonomy (1956) used nouns; 2001 revision used verbs (action-focused).
"What is Bloom's Taxonomy?" — Simon Sir is an educator — he asks this to check if you understand learning frameworks. Know the 3 domains and 6 cognitive levels. He may ask: "At which level of Bloom's Taxonomy is an oral examination?" — Typically Analysis and Evaluation levels.
- Curriculum: The overarching educational plan — the "big picture" covering all subjects, activities, and educational milestones of a course programme.
- Syllabus: A descriptive list of specific topics to be taught within a single subject. A subset of the curriculum.
"What is the difference between a curriculum and a syllabus?" — Simple but important for candidates preparing for shore-based instructor roles. One-liner answer: curriculum is the whole plan; syllabus is the topic list for one subject.
🔥 LSA & Survival Equipment
3 topicsDynamic Test — Every 5 Years
Tests for structural deformation or failure of launching appliances and on-load release gear.
Test load: 1.1 × (boat weight + full complement)
Factor of Safety — Falls: 6 | Structural components: 4.5
Static Test — Davit & Winch Brake Capacity
- Lifeboat hull removed; framework tested independently.
- Wind to maximum cable turns on drum.
- Apply static load = 1.5 × Maximum Working Load — held by mechanical brake only.
- Lower smoothly for at least 1 full revolution of brake drum.
- Inspect for permanent deformation; confirm brake holding capacity.
Annual Mandate
On-load release test must be performed annually.
"What is the dynamic test for lifeboats?" — Know the 1.1× load, 82.5 kg/person, FoS of 6 for falls, and the 1 m max drop after brake. He may follow with: "How often is the on-load release test done?" — Annually. And the dynamic test — every 5 years.
Certification height: measured from still water to lowest point of boat in lightest seagoing condition.
Key Requirements
- Safety harnesses: Must secure persons up to 100 kg.
- Positive headway: Must make positive headway after launch under up to 10° trim and 20° list.
- Activation systems: Two independent activation systems — crew must be able to test without launching.
- Survey check: Certification height and stowage height verified during initial SEQ survey.
"What are the requirements for a free-fall lifeboat?" — Know the stowage height rule (≤ certification height), 100 kg harness, and the trim/list limits. Vessels with free-fall lifeboats include some bulk carriers and tankers — not typical on container vessels, but examinable.
Painter Line System
- Attachment: Permanently attached to ship's structure via a certified weak link.
- Manual release: Must be capable of manual release.
- Hydrostatic release: Must also have automatic hydrostatic release activating at not more than 4 metres depth.
The weak link is designed to break under the inflated liferaft's buoyancy, allowing it to float free if the ship sinks rapidly.
"At what depth does the HRU activate?" — Not more than 4 metres. He may ask: "What is the breaking strength of the weak link?" — Must break at a load not exceeding the HRU's lashing strength (typically 2.2 kN). Know the purpose: if ship sinks rapidly, HRU + weak link allows liferaft to float free and inflate automatically.
⚙️ Systems & Technology
4 topicsFlash Point — Definition
The minimum temperature at which a liquid fuel emits sufficient vapour to form an ignitable mixture with air when exposed to an external ignition source.
Testing Methods
- Open Cup Method: For high flash-point fuels (typically >79°C).
- Closed Cup Method: Standard for volatile fuels across 40°C to 360°C range.
- Equipment: Pensky-Martens Closed-Cup Tester — industry standard.
Exception: ships using fuel with FP below 60°C must comply with special requirements.
"What is flash point and how is it tested?" — Know both methods, the Pensky-Martens tester, and critically the SOLAS minimum of 60°C for marine fuel. He may ask: "What is the flash point of HFO?" — Typically 60–100°C. MGO: typically >60°C.
