Surface Effect Ship with Four Air Cushions Part II: Roll and Pitch Damping
(Peer reviewed; Journal article, 2019)This paper introduce damping of roll and pitch motion on a Surface Effect Ship (SES) in low vessel speeds. The SES consist of two side-hulls, a reinforced rubber bow and stern seal skirt system and four air cushion. The ... -
A survey on modeling and control of thruster-assisted position mooring systems
(Peer reviewed; Journal article, 2020)This review presents a systematic summary of the state-of-the-art development of technological solutions, modeling, and control strategies of thruster-assisted position mooring (TAPM) systems. The survey serves as a starting ... -
Survey report for CRIMAC SFI 2023
(Toktrapport;, Research report, 2024)This cruise report describes the objectives, methods, and preliminary results from the tasks carried out at the CRIMAC SFI survey. The survey was conducted on board RV G.O. Sars between November 15th (Tromsø) and November ... -
Survivability of ships at sea: A proposed model to account for human factors in a safety critical system
(Journal article, 2014)Most serious accidents at sea are caused by minor incidents that escalated into an uncontrolled situation. This study is aiming to develop a model to investigate the likelihood of fatal accidents, given that a critical ... -
Suspended sediments due to random waves including effects of second order wave asymmetry and boundary layer streaming
(Journal article, 2015)The paper provides a practical stochastic method by which the suspended sediment concentration due to long-crested (2D) and short-crested (3D) nonlinear random waves can be calculated. The approach is based on assuming the ... -
Sustainable marine power system design with alternative fuels; A case study of energy efficiency and cost optimization
(Master thesis, 2022)Elektrifisering av skip viser til en ettertraktet besparelse av kostnader og utslipp, og kan oppnås med blant annet ombygging av konvensjonelle skip. En slik elektrifisering gjør design av skip mer liberalt og mer lettvint ... -
Sustainable Power System Design for Green Shipping - a case study of a cruise ferry
(Master thesis, 2021)En bærekraftig utvikling for fremtiden har aldri vært mer relevant ettersom det globale miljøavtrykk fortsetter å vokse. En reduksjon av utslippene som truer det globale livet slik vi kjenner det i dag, er viktig for å ... -
Sway Control on a Surface Effect Ship - using asymmetric vent valve opening
(Master thesis, 2016)The lateral maneuvering for Surface Effect Ships (SESs) in low velocities is highly limited. Due to SESs hull shape in the bow, it is not an option to use conventional means to get lateral thrust, such as tunnel- or ... -
Synergistic control barrier functions with application to obstacle avoidance for nonholonomic vehicles
(Chapter, 2021)Control barrier functions (CBFs) have recently emerged as a means to ensure safety of controlled dynamical systems. CBFs are suitable for obstacle avoidance, where the CBF is often constructed from the distance and relative ... -
A synthesis of feasible control methods for floating offshore wind turbine system dynamics
(Journal article, 2021)During the past decade, the development of offshore wind energy has transitioned from near shore with shallow water to offshore middle-depth water regions. Consequently, the energy conversion technology has shifted from ... -
System alternatives for modular, zero-emission high-speed ferries
(SNAME International Conference on Fast Sea Transportation;, Chapter, 2021)Low emission requirements exert increasing influence upon ship design. The large variety of technological options makes selecting systems during the conceptual design phase a difficult endeavor. To compare different ... -
System Based Design for Mobile Offshore Units
(Master thesis, 2014)This thesis seeks to investigate the possibilities of adapting the method of system based ship design developed by Kai Levander (2012), to be applied to MOU s. Design is the creation of a plan or construction of an object. ... -
