Ship motion-based wave estimation using a spectral residual-calculation
(Chapter, 2018)This paper presents a study focused on a newly developed procedure for wave spectrum estimation using wave-induced motion recordings from a ship. The particular procedure stands out from other existing, similar ship ... -
Ship Performance Monitoring using In-service Measurements and Big Data Analysis Methods
(Doctoral theses at NTNU;2022:101, Doctoral thesis, 2022)Ship performance monitoring is quite important for ship owners as well as charter parties to optimize their profits. Moreover, the regulatory organizations, like IMO, has also become interested here in order to maintain ... -
Ship Propulsion Dynamics and Emissions Gas Engine Methane Slip Reduction at Dynamic Loads
(Doctoral theses at NTNU;2021:261, Doctoral thesis, 2021)Continuous discharging of greenhouse gases into the atmosphere has motivated researchers to develop prime movers for working with less polluted energy sources. The low cost of natural gas relative to diesel and gasoline ... -
Ship trajectory prediction in confined waters.
(Master thesis, 2023)This thesis addresses the challenge of predicting vessel trajectories in confined waters, where the multi-dimensionality of the interaction scene introduces non-linearity in ship paths. The proposed approach utilizes machine ... -
Shipboard DC Hybrid Power Systems: Pathway to Electrification and Decarbonization
(Chapter, 2023)Ship power and propulsion systems are being electrified for several reasons out of which emission reduction, energy efficiency improvement, and ultimately reduction in operating expense (OPEX) are the main drives. ... -
Shipbuilding Cost Estimation: Parametric Approach
(Master thesis, 2013)A continuously increasing global competition in the ship building industry leads to decreasing margins and an increased cost pressure for Norwegian shipbuilders. The Norwegian ship designers and shipbuilders are known ... -
Shipping oil from the Russian Arctic: Past experiences and future prospects
(Journal article; Peer reviewed, 2015)Transport of oil from Russian Arctic ports to Western markets was insignificant prior to 2002. In 2002, there was a major surge, with 5 million tonnes delivered westwards through the Barents Sea. By 2004, this had increased ... -
Shipping Safety in the Arctic - Contributions to the understanding of shipping risk during escort and convoy operations
(Doctoral theses at NTNU;2024:200, Doctoral thesis, 2024)The decline in Arctic ice extent has drawn increasing attention to Arctic shipping. In comparison to traditional routes, Arctic routes offer substantial advantages, particularly in terms of time efficiency and cost ... -

Short-term extreme ice loads prediction and fatigue damage evaluation for an icebreaker
(Journal article; Peer reviewed, 2018)In this paper, the short-term extreme value statistics of the ice loads acting on ship hull and the fatigue damage due to ice loads actions are studied. Due to the stochastic nature of the ice-induced loads and randomness ... -
Shutdown preparedness monitoring
(Master thesis, 2011)Statoil is a prominent Norwegian actor in the oil and gas industry at home and abroad. Maintaining the offshore installations has gradually become more important in line with the installations age, increased HMS demands ... -
Significance of offshore wind farm sound on marine populations
(Master thesis, 2019)Offshore wind energy is one of the most important renewable energy globally. Currently, Europe is leading both in capacity and technology exports. Although Norway has significant wind resources, the development of offshore ... -
