MAS541 Marine Analyses

Contents and structure

The course provides an introduction to the use of commercial software (SESAM from DnV) for calculating hydrostatics/stability, hydrodynamic response and anchoring analysis for floating marine structures as well as the use of relevant regulations.

Content

• Theoretical review/explanation of basic concepts
• The possibilities and limitations of the software
• Practical use of the software for selected cases.

Learning Outcome

Upon completion of the course, the student shall have the following qualifications:

Knowledge

• can perform basic marine engineering load and response analyses (global analyses) for marine installations and offshore operations.
• has in-depth knowledge of calculation methodology, its possibilities and limitations.
• has a detailed understanding of the difference between frequency plan and time plan response analysis.
• can, based on the possibilities and limitations of the calculation methodology, apply knowledge to new marine engineering issues.

Skills

• can use dedicated commercial software (Sesam) for modeling various marine installations and offshore operations.
• can calculate hydrostatics and stability, and perform stability checks in relation to regulatory requirements according to intact and damaged conditions.
• can conduct a short-term hydrodynamic load and response analysis in the frequency plane. Present results based on statistical methods and understand the uncertainties associated with the results and conduct control of the response level in relation to current regulations.
• can conduct anchoring analyses in the time plane for intact and damaged (line breakage) conditions and assess the results against current regulations. If the analysis results are not in accordance with the requirements of the regulations, propose changes to the anchoring system that will change this.

General competence

• can use their knowledge and skills towards new marine installations and offshore operations and at the same time be aware of the possibilities and limitations of the methodology used.
• can work in a group and communicate technical results to both professionals and non-specialists.
• can contribute to new thinking and innovation.
• can reflect through their own professional practice and contribution to the group's results.

Entry requirements

None

Recommended previous knowledge

- MAS102 Marine Engineering

- MAS116 Hydrodynamics

or equivalent knowledge.

Teaching methods

The course is mainly project-based with group work under supervision, but some relevant theory will be lectured. Introduction to dedicated software through course activities will be provided. Each group consists of 3-4 students.

Compulsory learning activities

The following work requirements apply:

• Mandatory participation in courses in applied software, Sesam - 3 x 2 days.
• Mandatory participation in planned group work

Assessment

A combination of portfolio assessment and oral presentation (approx. 15 min + 10 Q&A). The portfolio assessment counts for 70% and the oral presentation counts for 30%.

Grading scale A-F, where F corresponds to fail.

The portfolio contains:

• Group report(s) per case with attachments, documenting calculations and results.
• Individual reflection note where the individual student reflects on their own contributions to the group delivery (report) as well as considerations regarding the working conditions and division of labor within the group.

The portfolio receives an overall grade for the entire group.

If there is any doubt as to whether a student has contributed sufficiently to receive credit for the group's joint product, this routine applies.

Examination support material

Portfolio assessment: all aids are allowed
