Subsea Survey, Positioning & Installation and Introduction to Subsea Control system
This course gives a detailed understanding of subsea field preparation operations. It discusses at length subsea survey techniques, how to position subsea systems on the seabed, subsea system installations and mathematics involved in rope selection for deployment. This course features case study of subsea system installation from project management perspective. It also introduces subsea control systems.
Outcome
- To gain total understanding of the basis, significance and application of subsea surveying techniques.
- To gain the knowledge required to understand the factors influencing the installation of subsea equipment including the effects of geotechnics.
- Understanding of the methods and equipment used for subsea installation of pipelines, risers and umbilicals.
