Learning Outcome

-Knowledge:

The students

• can explain the challenges the subsea environment represents for constructions and equipment which is used subsea;
• have basic knowledge of typical field development where subsea production systems are extensively used;
• have knowledge of subsea production systems, including drilling and completion of wells, equipment and maintenance-/intervention methods;
• can explain methods for subsea operations, including the use of remotely operated  and programable vehicles (ROV/AUV), diving and relevant surface vessels;
• have knowledge of reliability and risk analysis methods and apply them on equipment and operations;
• have basic knowledge of components and control equipment used in hydraulic systems and know how to integrate them in functional systems;
• can explain the sources and consequences of contaminants in the oil, and how this can be prevented;
• have knowledge of regulation of pump capacity in hydraulic systems;
• can explain the sources of noise and methods for noise attenuation in the hydraulic system.

-Skills:

The students are able to

• design mechanical equipment for subsea applications;
• perform hydrodynamical calculations for subsea lifting- and ROV-operations;
• prepare operation procedures related to installation and maintenance/intervention;
• design basic hydraulic systems based on standard components;
• evaluate the technical characteristics of the hydraulic components in the system.
