About the course

The aim of this course is to provide the participants with a complete and up-to-date overview of offshore structures engineering in general and steel jackets in particular. It will give a picture of the work of ocean and structural design engineers, using case studies to highlight the topics discussed. This course will illustrated all information about fixed offshore structure platform.

The basic design and loads that affect the offshore structure platform will be discussed in detail with the up to date method of structure analysis as the pushover structure analysis. The selection of the proper configuration and layout of the platform will be illustrated. The construction and repair of the mature structure will be discussed in this course. The risk based under water inspection with up to date methodology will be presented in this course.

Course Objectives

Upon successful completion of this course, the delegates will be able to:

  • Have a great understanding of the planning, concept development, design, construction, installation, operation, inspection and maintenance of Offshore Structures
  • Provide participants with an understanding of the design, construction and risk based maintenance for offshore platforms, specifically, the theory and process of such design
  • Understand the use of current, applicable engineering methods in the design of fixed offshore platform
