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

After having completed the course the students shall have obtained a basic understanding of the processes in the world ocean as well as in design, contruction and working principle of various underwater systems. Specific learning objectives are: Basic knowledge of the world oceans, including depths, ocean currents, temperature conditions and salinity/seawater density. Knowledge and understanding of design and operational conditions for the main underwater vehicles as ROV’s and AUV’s. Beeing trained in and able to plan and perform complex underwater tasks as search for and resque lost objects as boats aircrafts and others from various depths, incfluding preserving of them after being brought to surface. Know and understand various underwater positioning and navigational systems. Being able to wright (group) reports about complex underwater operations, including time surveying of the mother ship. Knowledge related to important issues that
need to be considered during design, installation and operation of offshore pipelines. Being able to perfrom simple calculations related to installation, wallthickness design and insulation design.

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.
