(Journal article; Peer reviewed, 2017)
In this work, the path integration method and the energy-based stochastic averaging method are introduced in order to study the stochastic responses of ship roll motion in random beam seas. Based on the Markov property of ...
• #### Comparative study on the dynamic response of a Spar type buoy and a Sevan type cylinder floating production unit ﻿

(Master thesis, 2012)
Comparative study on the dynamic response of a Spar type buoy and a Sevan type cylinder floating production unit
• #### Comparison between Measured and Calculated Riser Response ﻿

(Master thesis, 2012)
Well intervention operations can inflict large strains on a wellhead. The seabed in the North Sea is very rigid up to the point where the sea water meets the mud or sand. This is one of the reasons why wellheads operating ...
• #### A Comparison of Methods for Estimation of Fatigue and Extreme Mooring Response for a Floating Spar Wind Turbine ﻿

(Master thesis, 2015)
Hywind Demo is one of the worlds first floating offshore wind turbines. It is operated by Statoil and located off the coast of Karmøy in Norway. The substructure is a spar shaped hull, and it is moored with catenary mooring ...
• #### Concept Study and Analysis of a Constant Buoyancy System for a Floating Single Column Platform ﻿

(Master thesis, 2018)
The main objective of this thesis is to study a new platform concept which utilizes a submerged air volume for maintaining constant buoyancy. The work is motivated by the possible application as pontoons for floating bridges ...
• #### Concept Study and Analysis of a Floating Bridge ﻿

(Master thesis, 2017)
A floating bridge is a structure carrying traffic across a body of water and whose supports floats on the surface. The history of the floating bridge goes as far back as around 2000 BCE, when their use was mainly military. ...
• #### A Concept Study of a Pre-tensioned S-shaped Pontoon Bridge with Submerged Floating Twin-Tubes ﻿

(Master thesis, 2018)
The marine bridge differs from a regular bridge by using buoyancy units, often so-called pontoons, to obtain vertical equilibrium instead of rigid foundations. The term may include floating bridges, such as typical pontoon ...
• #### Constructive Alignment in Science and Engineering: From Principle to Practice ﻿

(Journal article; Peer reviewed, 2019)
This paper reports on an action research study on task design and constructive alignment in an optional module at the Norwegian University of Science and Technology. While students appreciated the two professors’ teaching, ...
• #### Contour Methods for Deepwater Riser Systems ﻿

(Master thesis, 2014)
