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 ROVs and AUVs.

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.

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. Examination papers will be given in English only. Students are free to choose

Norwegian or English for written assessments. Portfolio assessment is the basis for

the grade in the course. The portfolio includes a final written exam (60%) and

exercises (40%). The results for the parts are given i %-scores, while the entire

portfolio is assigned a letter grade. Postponed/repeated exams may be oral.
