01
Major Certificates & Documents to Carry On Board
The SOLAS, MARPOL, Load Line, Tonnage, STCW, ILO and liability certificates and documents a surveyor expects you to name.
02
The Saturday Routine: Planned Maintenance Checks
The weekly, fortnightly and monthly emergency and safety-equipment checks every engineer performs, and who is responsible for each.
03
Dry-Docking: Preparation, Procedure & Survey
What the engineer prepares months, days and hours before docking, what happens on the dock, and the survey and follow-up work.
04
Bunkering & Oil Transfer: Precautions & Procedures
The scuppers, hoses, signals and tank-changeover discipline that prevent a spill and a bad fuel problem.
05
Conditions of Assignment of Freeboard
The construction, openings, vents, scuppers, side scuttles, freeing ports and crew protection that must be met before a freeboard is assigned.
06
Why Oil Tankers Have Less Freeboard
Fewer openings, more subdivision, low tank permeability, lighter cargo and powerful pumping — the reasons a tanker needs less reserve buoyancy.
07
Safety on Oxygen & Acetylene Bottles
Flashback arrestors, colour coding, right/left-hand threads and separate storage — the rules for oxy-acetylene equipment on board.
08
Tonnage Measurement: Gross & Net Tonnage
The Tonnage Convention 1969, the GT and NT formulas, the deduction spaces and why tonnage drives regulation and port costs.
09
Load Line: Marks, Letters & Conventions
The Plimsoll mark, TF/F/T/S/W/WNA letters, how the marks are derived, the Load Line Convention and why the mark is on both sides.
10
Loadicator / Loading Computer
The onboard loading computer that proves adequate stability, allowable stresses and draughts before the ship sails.
11
Difference Between Audit and Survey
A survey checks the hardware; an audit checks the system, procedures and records behind it.
12
Emergency Generator: Testing & Requirements
Two starting modes, the weekly/monthly test schedule, battery/hydraulic/automatic start procedures and the stored-energy rules.
13
Starting Air Compressors, Receivers & Air Bottle Safety
Two compressors, the 15-to-25 bar in 30 minutes rule, the 12/6-start capacity and the mountings that keep an air bottle safe.
14
MGPS — Marine Growth Prevention / Anti-Fouling System
How copper and aluminium anodes use electrolysis to stop marine growth and corrosion in the sea water cooling system.
15
Quick Closing Valve: Construction & Working
The remote spring-loaded valve that shuts off fuel in an emergency, and how it differs from a pressure relief valve.
16
How to Measure the Depth of the Ship (Echo Sounder)
The echo sounder measures depth from the time a sound wave takes to travel to the seabed and back: S = V × T.
17
New Amendments (1 January 2013): SOLAS & MARPOL
The 2013 amendments: lifeboat on-load release hooks, EEDI/SEEMP energy efficiency, the US Caribbean ECA and the revised garbage rules.
18
Ship Accommodation, Midship Section & Container Stowage
Knowing your ship's particulars, the midship section, TEU/FEU container sizes and tare, net and gross weights.
19
Rudder: Construction, Types & Support
How a rudder is built, the balanced/semi-balanced/spade types, and how it is supported and prevented from lifting.
20
Fuel Consumption & Speed Relationship
Why fuel burn climbs with the cube of speed — specific fuel consumption, the fuel coefficient, and daily consumption.
21
Maritime Codes & Conventions: The Complete List
The codes and conventions every marine engineer must name — and what each abbreviation actually stands for.
22
STCW: The Convention & Its Eight Chapters
What STCW stands for and the eight chapters that set the training, certification and watchkeeping standard for seafarers.
