Subsea Structures Training

About the Course

The course focuses on subsea systems from design and installation through to operation. This course explains how the whole system works in conjunction.

The course gives detailed idea about design, analysis, construction and installation aspects of subsea manifolds, SSIV structures, wellhead protection structures, integrated drilling/manifold templates, riser bases and flexible riser system ancillary equipment. The design part also includes the strength evaluation of suction piles which supports the subsea structures.

The course gives in-depth, technical aspects detailing the engineering behind Flow line installations, Riser, umbilical and its substructures spool installations.

The course content gives a brief description about the subsea installation process, different methods of installation, and the different types of subsea installation vessels.

Who should attend?

Engineers and researchers involved in the design of subsea structures and subsea systems, Contracts engineers, Flowline engineers, Team leaders, Conversion Engineers, Pipeline engineers, Project engineers and managers, Subsea and offshore controls engineers, Safety inspectors will benefits from attending this course. The course is innovative in both content & structure with a careful balance of theory & practice.
