Course requirements
Enrolment in a relevant PhD programme. Knowledge in mathematics and physics at master level.
Academic content
The course addresses analyses done in the offshore sector to provide safe and sound developments of Arctic offshore fields and operations. Offshore structures are discussed on the basis of characteristics of the physical environment.
Specific topics
- ice physics/mechanics
- bearing capacity of ice
- metocean and Ice Design Basis
- statistical treatment of data
- modelling of ocean waves, currents, sea ice, and iceberg drift and decay
- design of structures for Arctic offshore field developments
- ice action and action effects on structures / harbours (field study)
- use of ice tank testing in design of offshore and coastal structures
- physics-based numerical modelling of ice action and action effects on structures
- collision studies/structure damage assessment
- use of numerical models to design/optimize Arctic offshore operations
- station keeping in ice (mooring/DP)
- ice management
- effects of marine icing.
Learning outcomes
Upon completing the course, the students will:
Knowledge
- have basic understanding of the physics and mechanics of ice
- understand how the physical environment affects the design and operations of offshore structures in the Arctic, and how the structures respond to environmental actions. Logistics is part of this.
The environmental actions relate to effects from metocean conditions including sea ice and icebergs, marine icing, and sea ice dynamics.
Skills
- skills in designing and operation of offshore structures in the Arctic.
General competences
- competence developed through lectures and group work related to a relevant case study.
Learning activities
The course extends over 2 weeks including compulsory safety training and is run in combination with AT-327.
Students, normally two in a team, are required to prepare a report of about 5000 words (including text, references, figures and tables) on a chosen research topic. The students are supposed to work on the report after the two-week course period at UNIS and submit the report in December the same year. The total workload of the course is estimated to 250 hours.
The written exam will be arranged in late November / early December. The exam can on request be arranged at UNIS, NTNU, UiT The Arctic University of Norway, UiS and TU Delft
Summary
- Total lecture hours: Ca. 44 hours.
- Group work: 10 hours.
Compulsory learning activities
- Participation in group work.
- All compulsory learning activities must be approved in order to sit the exam.
Assessment
- All assessments must be passed in order to pass the course.
