Aims

A1: To gain the knowledge and understanding of different configurations, components and equipment used in mooring and riser systems.
A2: To address the theoretical and practical aspects of mooring and riser systems.
A3: To develop students' skills in designing and analysing mooring and riser systems.
A4: To gain the knowledge and understanding of elemental concepts of drilling engineering.

Outline Of Syllabus

Mooring configurations: single-leg mooring, spread mooring, turrent mooring; mooring components: wire ropes, synthetic fibre ropes, chains, clump weights, drag and suction anchors, piles; winches and windlass; single component and multi-component catenary equations; soil-mooring interaction; mooring failure modes; static, quasi-static, and dynamic mooring analyses; mooring design criteria and considerations.
Drilling risers, production risers: flexible, steel catenary; flexible riser configurations: steep/lazy S and wave, free hanging; flexible riser components: bend stiffeners/ bellmouths, unbonded/bonded flexible risers, bend restrictors; rigid riser components: tieback connectors, stress joints, riser joints and connectors, buoyancy modules, tensioners; riser casing; soil-riser interaction; riser failure modes; structural riser analysis; static and dynamic riser analyses; interference analysis; riser design criteria and considerations.
Fundamentals of drilling engineering, the oil well, drill string design, drill bits, straight hole drilling, directional drilling, casing and cementing, offshore drilling.

Teaching Methods

Please note that module leaders are reviewing the module teaching and assessment methods for Semester 2 modules, in light of the Covid-19 restrictions. There may also be a few further changes to Semester 1 modules. Final information will be available by the end of August 2020 in for Semester 1 modules and the end of October 2020 for Semester 2 modules.

Teaching Rationale And Relationship

Lectures are designed to convey the underlying concepts and knowledge of mooring and riser systems (IKO1 – IKO6), drilling systems (IKO7 - IKO8) and the professional skills required to design and analyse mooring lines, risers and drill strings (ISO1 – ISO8).

Practicals sessions are a mix of supervised and self-organising activities in which the students develop intellectual and problem-solving skills to design and analyse mooring and riser systems (ISO1 – ISO6).

Independent study gives time for the students to read recommended references (IKO1 – IKO8) and practise their professional skills (ISO1 – ISO8).

Assessment Rationale And Relationship

• An unseen examination enables students to demonstrate their theoretical understanding (IKO1 – IKO8) 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' are also assessed in these ways.
