Hydraulic systems/circuits, hydraulic fluids, oil quality/oil analysis, fluid mechanics, pumps and motors, control valves, tanks, filters, coolers, couplings and pipes, noise and noise reduction in hydraulic installations.

Learning Outcome


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.


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.

-General qualifications:

  • are able to keep themselves updated in a subject of rapid development;
  • can apply standards and guidelines related to general engineering work.
