The LPG Carrier Operations and Cargo Handling Training Course offered by Oxford Training Centre is designed to develop the technical knowledge and operational skills required for the safe and efficient transportation of liquefied petroleum gas (LPG) by specialised gas carriers. LPG transportation involves complex vessel systems, specialised cargo equipment, strict safety procedures and careful coordination between shipboard personnel and shore-based facilities. This programme provides a comprehensive understanding of LPG carrier operations, covering vessel characteristics, cargo properties, loading and discharging procedures, cargo containment systems, refrigeration arrangements and operational controls. As part of the Shipping, Maritime and Ports Training Courses, it addresses the practical requirements of professionals responsible for managing LPG vessels and maintaining safe maritime cargo operations.
Participants will explore the technical and operational aspects of gas carrier operations, including cargo planning, tank preparation, ship-to-shore communication, cargo transfer procedures, pressure and temperature management, and emergency response. The course also examines LPG cargo handling practices, cargo compatibility, vapour management, operational monitoring and the prevention of leakage, fire and explosion incidents. Particular attention is given to cargo safety, international maritime requirements, shipboard risk assessment and the responsibilities of officers and crew during cargo operations. Through practical examples and operational scenarios, participants will strengthen their ability to supervise cargo transfer, identify potential hazards, respond to abnormal conditions and maintain compliance with relevant maritime safety standards.
