Course content

In the introductory part composition and properties of ocean sea water is dealt with, also with purpose to serve as basis for the understanding of sound transmission, light conditions and primary production in the oceans. Then it explains how this knowledge is applied in underwater instruments for positioning, signal transfer, mapping, measurements and experimental samling. The main course content deals with systems for transport and operation in the ocean space as well as methods for calculation of the influence of the ocean current and vessel movement on hanging loads and ROVs. Also design, operation and evaluation of the properties of manned, remote controlled and autonomous systems are dealt with. The course also include a description of relevant topics related to development of subsea pipeline systems such as system design, material selection, welding, wall thickness design, hydrodynamic stability, problems related to free-spans on uneven seabed, thermal expansion behavior, intervention, tie in to end infrastructures and ready for operation.

Learning outcome

Obtain a basic understanding of the processes in the ocean and design, contruction and working principle of various underwater systems. The course forms the basis for more advanced courses in underwater technology.

Learning methods and activities

Lectures, practical training with ROV's. Two project works after the lecture part shall be performed as student group works. All group members will in principle get the same marks.

Recommended previous knowledge
