    Dual-Fuel Marine Technical Services | FGSS Training

    The FGSS (Fuel Gas Supply System) is the "energy heart" of a dual-fuel vessel, and its stable operation affects voyage safety, personnel safety and commercial performance. Safe operation depends not only on quality equipment and professional maintenance but on people who understand the system, can operate it correctly and can respond in an emergency — and FGSS training is how those people are developed. Our FGSS training complements certification courses such as T11/T12, with a stronger emphasis on linking theory to practice.

    1. Why FGSS training is necessary

    The media handled by the FGSS are cryogenic, high-pressure and flammable, so the operating threshold is high and safety requirements are strict. Professional training is urgent for three reasons:

    • A highly specialised system: the FGSS integrates several functional modules with complex process flows; only professional training gives a full grasp of the principles and prevents operating errors.
    • Demanding safety requirements: the IGF Code and classification society requirements must be followed strictly, and training helps personnel master the safety essentials and guard against risk.
    • Human factors are a leading source of risk: most shipboard safety incidents originate in improper operation, and training is an effective way to reduce human error and accidents.

    2. Who the training is for

    Safe FGSS operation involves the whole process, and the training covers the key roles so that every function is properly equipped:

    • Crew (engine and deck): responsible for daily operation and parameter monitoring, they need fluency in operating procedures and basic emergency skills.
    • Owner's technical management staff: responsible for maintenance planning and compliance oversight, they gain command of system characteristics, safety risks and classification society requirements.
    • Shipyard commissioning and maintenance personnel: responsible for installation, commissioning and troubleshooting, they need to know the system architecture, quality control points and fault-handling logic so that commissioning and repair meet the standard.

    3. Training content

    The training is practical and centred on the full FGSS operating process, so that what is learned can be applied with visible effect:

    • System principles and structure: core components are broken down, with their working logic and interaction explained, laying the foundation for operation and maintenance.
    • Normal operating procedures: start-up and shutdown, parameter adjustment and routine inspection steps are standardised, correcting poor practice and removing latent risk.
    • Abnormal conditions and emergency response: real cases are used to explain fault diagnosis methods and emergency procedures, reducing the consequences of incidents.
    • Safety rules and classification society requirements: safety legislation, explosion-protection rules and class standards are explained so that the compliance baseline is clear and surveys are passed smoothly.

    4. Training formats

    A range of formats is used to suit the role, balancing professional depth with practical use:

    • Theory plus case studies: a solid theoretical grounding combined with analysis of real cases, avoiding any gap between theory and practice and improving retention.
    • On-site practical training: one-to-one hands-on guidance on board, with simulated operation and troubleshooting scenarios, so that trainees can apply what they learn immediately.
    • Project-specific training: programmes tailored to the requirements of owners and shipyards, addressing specific pain points and raising the practical value of the training.

    5. Summary

    FGSS safety and stability depend on every person who understands the system. Professional FGSS training transfers skills and strengthens safety, giving participants a thorough grasp of the system, disciplined operating practice and sound emergency response.

    Good FGSS training is the foundation of safer, more stable operation. Training well and building a professional team is how the safety line is secured for every voyage.

    Tecway has an experienced FGSS service team that has taken part in and successfully completed numerous newbuilding and retrofit projects, building up solid engineering practice along the way.

    Drawing on a mature technical framework and proven site implementation capability, we provide whole-life technical support for FGSS projects, covering design optimisation, installation guidance, commissioning support, risk control and long-term operation and maintenance, so that projects are delivered safely, run stably and continue to create value.
