Basic Design of Subsea Structure Course

this course will review the fundamentals behind all types of fixed offshore structures and, in the case of fixed platforms, will cover applications of these principles. The overall objective is to provide participants with an understanding of the design, construction and risk based maintenance for offshore platforms, specifically, the theory and process of such design and the use of current applicable engineering methods in the design of fixed offshore platforms.

This training course will feature:

  • Case studies on petroleum industry
  • Codes and standards with technical practice
  • The new trend of integrity management system
  • The engineering and pitfalls in construction
  • The pushover structure analysis technique
  • ROV under water inspection and CP system design

At the end of this training course, participants will be familiar with:

  • Offshore steel structure design overview
  • Offshore structure platform
  • The loads applied on offshore structure platform
  • The modern technique on the risk based inspection for maintenance plan for fleet platforms

This training course uses both conventional and non-traditional techniques. It utilises small group and facilitated plenary discussions as well as instruction to explore key concepts, models, tools and techniques. Hands-on exercises and case studies are used to practice the application of knowledge and use of skills. Structured reviews provide the opportunity to consider how the learning can be applied to the delegates’ own work.
