Teaching Rationale And Relationship

Lectures are designed to convey the underlying concepts and knowledge of mooring and riser systems (IKO1 –
IKO3), drilling systems (IKO4) and the professional skills required to design and analyse mooring lines, risers
and drill strings (ISO4 – ISO7).

Tutorial sessions are a mix of supervised and self-organising activities in which the students develop intellectually and problem-solving skills to design and analyse mooring and riser systems (ISO1 – ISO4).

The formal lectures provide an effective method for students to work through materials at their own pace allowing them to develop an in-depth understanding and familiarity with the fundamentals of subsea engineering and pipeline engineering (IKO5 – IKO10).

Independent study gives time for the students to read recommended references (IKO1 – IKO10) and practise their professional skills (ISO1 – ISO8).

Assessment Rationale And Relationship

The examination is an appropriate way to assess both theoretical understanding and problem solving skills under time-constraint as required in industry. The assignments enable a more realistic engineering problem to be set to assess subject specific and cognitive skills. Two ‘low stakes’ coursework assignments (<30%) are incorporated in this module as they are found beneficial for one year Master’s programme.

An unseen examination enables students to demonstrate their theoretical understanding (IKO1 – IKO10) and
professional skills (ISO1 – ISO8) under time-constraint as required by industry.
The Prob Solving exercise on the design and analysis of a mooring and riser system and the Case Study on drilling
technology development tests the students’ ability to write reports, apply the taught professional skills and solve
mooring and riser problems (ISO1 – ISO8). The Graduate Skills Framework entries indicated as 'A' is also
assessed in these ways.
Knowledge and understanding are assessed via the unseen written examination and the Prob Solving Exercise and
Case Study assignments. Subject-specific and cognitive skills are assessed via the module assignment, as are communication skills. The Graduate Skills Framework entries indicated as (A) are also assessed in this way.
