Course description for academic year 2020/2021
Contents and structure
The influence of subsea environment on technical systems, Subsea production, remotely operated vehicle (ROV/AUV), Diving, Surface vessels for subsea operations, Hydrodynamic calculations, analysis of safety and reliability.
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.
- 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.
- are able to keep themselves updated in a subject of rapid development;
- can apply standards and guidelines related to general engineering work.
