SCOUR BELOW PIPELINES AND AROUND VERTICAL PILES DUE TO RANDOM WAVES PLUS CURRENT ON MILD SLOPES
(Master thesis, 2014)This thesis presents a stochastic method for predicting the scour depth around vertical circular slender piles and below marine pipelines due to random waves plus current on mild sloping seabeds. An overview of the scour ... -
Scour below pipelines due to random waves alone and random waves plus currents on mild slopes
(Journal article, 2017)This paper provides a practical stochastic method by which the maximum equilibrium scour depth below a pipeline exposed to random waves plus a current on mild slopes can be derived. The approach is based on assuming the ... -
Screening LCA of GHG emissions related to LNG as ship fuel
(Master thesis, 2012)In view of the increasingly popular climate change debate worldwide, maritime transport is under pressure to create sustainable solutions for a cleaner future.One of these solutions is using liquefied natural gas (LNG) as ... -
Sea floor geometry approximation and altitude Control of ROVs
(Journal article; Peer reviewed, 2014)This paper presents a method for sea floor geometry approximation in a local region beneath a remotely operated vehicle (ROV) for use in altitude control. The method is based on Doppler velocity log (DVL) altitude measurements ... -
Sea Loads on Closed Flexible Fish Cages
(Doctoral theses at NTNU;2018:28, Doctoral thesis, 2018)Norway has become the world's largest producer of Atlantic salmon through the use of open net structures in the sea. The aquaculture facilities have grown in both size and number. Currently, the industry faces increased ... -
Sea Passage Scenario Simulation for Ship System Performance Evaluation
(Doctoral theses at NTNU;2019:265, Doctoral thesis, 2019)This thesis addresses evaluation of ship system operational performance exposed to ocean waves for providing enhanced evaluation capabilities in the transition towards environmentally friendly shipping. It proposes and ... -
Sea state estimation based on vessel motion responses: Improved smoothness and robustness using Bezier surface and L1 optimization
(Peer reviewed; Journal article, 2021)Floating structures oscillate in waves, where these wave-induced motions may be critical for various marine operations. An important consideration is thereby given to the sea states at the planning and operating stages for ... -
Sea state estimation using model-scale DP measurements
(Chapter, 2015)Complex marine operations are moving further from shore, into deeper waters, and harsher environments. The operating hours of a vessel are weather dependent, and good knowledge of the prevailing weather conditions may ... -
Sea state estimation using multiple ships simultaneously as sailing wave buoys
(Journal article; Peer reviewed, 2019)The article presents initial ideas towards a network-based approach for sea state estimation used for marine operations and other maritime applications. In principle, all available means, ranging from in situ buoys, fleet ... -
Sea State Estimation Using Quadratic Discriminant Analysis and Partial Least Squares Regression
(Journal article; Peer reviewed, 2019)This paper proposes non-model based sea state estimation methods for a dynamically positioned vessel. Sea state estimation entails finding the wave direction, significant wave height and peak wave period and is done based ... -
Sea state estimation using vessel response in dynamic positioning
(Journal article; Peer reviewed, 2018)This paper presents a novel method for estimating the sea state parameters based on the heave, roll and pitch response of a vessel conducting station keeping automatically by a dynamic positioning (DP) system, i.e., without ... -
Sea State Limitations for the Deployment of Subsea Compression Station Modules
(Master thesis, 2012)Deployment of a large box structure in many sea states has been investigated. Two deployment methods are compared; crane installation over the side and through moonpool installation. The structure is 12 [m] long, 6 [m] ... -
