DGS-GASCO Advanced Training for Liquefied Gas Tanker Cargo Operations
DGS-GASCO: Advanced Training for Liquefied Gas Tanker Cargo Operations
Course Scope
The course is to give seafarers the essential education and training in tanker cargo operations to meet the knowledge, understanding and proficiency requirements set out by the IMO Convention on Standards of Training, Certification and Watchkeeping, STCW A-V/1-2, Table A-V/1-2-2. The course is designed for senior officers requiring specialist training for LIQUEFIED GAS tanker operations at a management level.
Course Aims
The course provides the necessary underlying knowledge, and understanding to make the participants proficient and competent on board a LNG tanker to,
- Safely perform and monitor all cargo operations with the knowledge, understanding and proficiency in design and characteristics of a liquefied gas tanker; Knowledge of cargo pumps and equipment and their safe operation; Loading, unloading, care and handling of cargo; in tanker safety culture and safety management; including cargo measurements
- Become Familiar with physical and chemical properties of liquefied gas cargoes having gained the knowledge, understanding and proficiency of basic chemistry and physics and including understanding the information contained in a Material Safety Data Sheet (MSDS)
- Take precautions to control and prevent hazards with the knowledge, understanding, and proficiency of hazards and control measures associated with liquefied gas tanker cargo operations and to calibrate and use monitoring and gas-detection systems, instruments and equipment
- Apply occupational health and safety precautions with the Knowledge, understanding, and proficiency of safe working practices, including risk assessment and personal shipboard safety relevant to liquefied gas tankers
- Respond to emergencies with the Knowledge, understanding, and proficiency of liquefied gas tanker emergency procedures following spillage of toxic or flammable vapour with medical first-aid procedures and antidotes on board liquefied gas tankers
- Take precautions to prevent pollution of the environment with the Knowledge, understanding, and proficiency to prevent pollution of the atmosphere and the environment
- Monitor and control compliance with legislative requirements with the Knowledge, understanding, and proficiency of relevant provisions of the IMO instruments; and the use of the IGC Codes and USCG rules and guidelines
