FLNG Operation and Maintenance

FLNG Operation and Maintenance


For the successful operation of the LNG FPSO (FLNG), it is of vital importance to understand the process from well operation and subsea control, to separation, dehydration, liquefaction, storage and offload. The 5-day training seminar focuses on in maintaining the high level of safety and security during the entire process.

The training seminar highlights the key technical challenges and risks associated the operation and maintenance of an FLNG. It will arm the participant with a wealth of knowledge to help them advance their project.

This training seminar will feature:

  • Operation and maintenance – Guidance and General Requirements
  • Environmental Influences affecting FLNG operation
  • Gas treatment
  • Liquefaction
  • Storage requirements
  • Offloading operations
  • Control and safety systems
  • Safety in operation and maintenance


By the end of this training seminar, participants will be able to:

  • Identify the key operational requirements
  • Recognize the effects of the ocean environment on FLNG operation
  • Understand tank cooling procedures and controlling the boil-off during tank filling
  • Interpret process plant behaviour
  • Appreciate safety in operation and maintenance

Training Methodology

This training seminar will utilise a variety of proven adult learning techniques to ensure maximum understanding, comprehension and retention of the information presented. The daily workshops will be highly interactive and participative. This involves regular discussion between both delegates and training seminar director. The training seminar will provide the participant with an in-depth knowledge through detailed information, real-life case studies, photos and video animation.

Organizational Impact

For the operation and maintenance of an LNG FPSO, a firm knowledge of all systems is essential. To ensure the smooth day-to-day running of the vessel it is important to have educated, knowledgeable and well-trained personnel that:

  • Understand the entire vessel and the LNG FPSO concept
  • Is aware of the equipment operating conditions
  • Understand the operation and interaction with process systems
  • Is aware of safety in operation and maintenance

In sending delegates to this training seminar, the organisation will gain the following benefits:

  • Develop a technically strong team
  • Increase efficiency
  • Optimize production performance at lower costs
  • Reduce maintenance cost over the lifetime of the equipment
  • Increase safety levels
  • Minimize downtime
  • Ensure environmental compliance

Personal Impact

Understanding of the entire system (process and marine) will provide the participants with the tools necessary to find answers and solutions and make appropriate decisions to progress in present and future positions.

This training seminar will provide multidisciplinary understanding of:

  • Applicable procedures and guidelines
  • The impact of the ocean environment on operation
  • The impact of the process system on safety
  • Maintenance of equipment and preventing problems
  • Handling hazardous situations (HAZID, HAZOP, risk assessment, etc.)
  • How and why things could go wrong

Who Should Attend?

This training seminar is suitable to a wide range of professionals but will greatly benefit:

  • Technical staff, project engineers, engineering discipline leads, engineering specialists, and operating staff
  • Maintenance technicians, supervisors, and managers, as well as other non-engineering personnel
