Reliquefaction systems. Cargo Emergency Shut Down system (ESD). Custody transfer system. Pump theory and characteristics, including types of cargo pumps and their safe operation
  • Effect of bulk liquid cargoes on trim and stability and structural integrity
  • Tanker safety culture and implementation of safety management requirements
  • Safe preparations, procedures and checklists for all cargo operations, including: post docking and loading: tank inspection, inerting (O2 reduction, dewpoint reduction), gassing-up, cooling down, loading, deballasting, sampling, including closed-loop sampling; sea passage: cooling down, pressure maintenance, boil-off, inhibiting; unloading: unloading, ballasting, stripping and cleaning systems, systems to make the tank liquid-free; pre-docking preparation: warm-up, inerting, gas-freeing; ship-to-ship transfer

  • Management and supervising of personnel with cargo-related responsibilities
  • Basic chemistry and physics and the relevant definitions related to the safe carriage of liquefied gases in bulk in ships. The chemical structure of gases. The properties and characteristics of liquefied gases (including CO2) and their vapours, including: simple gas laws; states of matter; liquid and vapour densities; diffusion and mixing of gases; compression of gases; reliquefaction and refrigeration of gases; critical temperature of gases and pressure; flashpoint, upper and lower explosive limits, auto-ignition temperature, compatibility, reactivity and positive segregation of gases; polymerization; saturated vapour pressure/reference temperature; dewpoint and bubble point; lubrication of compressors; hydrate formation. The properties of single liquids. The nature and properties of solutions. Thermodynamic units. Basic thermodynamic laws and diagrams. Properties of materials. Effect of low temperature – brittle fracture. Information contained in a Material Safety Data Sheet (MSDS)

  • Calibration and use monitoring and gas detection systems, instruments and equipment. Dangers of non-compliance with relevant rules/regulations
  • Safe working practices, including risk assessment and personal shipboard safety relevant to liquefied gas tankers. Precautions to be taken when entering enclosed spaces (such as compressor rooms), including the correct use of different types of breathing apparatus. Precautions to be taken before and during repair and maintenance work, including work affecting pumping, piping, electrical and control systems. Precautions for hot and cold work. Precautions for electrical safety. Use of appropriate Personal Protective Equipment (PPE). Precautions for cold burn and frostbite. proper use of personal toxicity monitoring equipment
  • Liquefied gas tanker emergency procedures. Ship emergency response plans. Cargo operations emergency shutdown procedure. Emergency cargo valve operations. Actions to be taken in the event of failure of systems or services essential to cargo operations. Fire-fighting on liquefied gas tankers. Jettisoning of cargo. Enclosed space rescue.
  • Actions to be taken following collision, grounding or spillage and envelopment of the ship in toxic or flammable vapour.
  • Medical first-aid procedures and antidotes on board liquefied gas tankers, with reference to the Medical First Aid Guide for Use in Accidents involving Dangerous Goods (MFAG)
  • Procedures to prevent pollution of the environment relevant provisions of the International Convention for the Prevention of Pollution from Ships (MARPOL) and other relevant IMO instruments, industry guidelines and port regulations as commonly applied
  • Proficiency in the use of the IBC and IGC Codes and related documents
