(Master thesis, 2010)The objective of this diploma thesis is to assess the technical and operational challenges EU Directive 2005/33/EC will introduce. This is done using fundamental knowledge about naval architecture and marine diesel engines. ... -
Techno-economic modeling of zero-emission marine transport with hydrogen fuel and superconducting propulsion system: Case study of a passenger ferry
(Peer reviewed; Journal article, 2023)This paper proposes a techno-economic model for a high-speed hydrogen ferry. The model can describe the system properties i.e. energy demand, weight, and daily operating expenses of the ferry. A novel aspect is the ... -
Technology Transfer in Novel Ship Design: A Deep Seabed Mining Study
(Journal article, 2022)Designing new ships for new purposes, in this case deep seabed mining, without using proper selected reference vessels, if available, is challenging. In this paper, we show that the vessel features of a future deep seabed ... -
Temperature-dependent characteristics of DH36 steel fatigue crack propagation
(Peer reviewed; Journal article, 2020)DH36 steel is a widely used material in marine engineering. The fatigue crack propagation rates of DH36 steel at low temperatures has a crucial influence on the fatigue strength of structures operating in polar environments. ... -
Temporally Deconflicted Path Planning for Multiple Marine Vehicles
(Master thesis, 2019)Over the past few years, growing interests and demands have been witnessed in the development of Automatic Surface Vehicle(ASV) operation, especially in controlling fleet of vehicles to perform complex missions. Basing on ... -
Tensegrity-Based Semi-Submersible Support Structure for a Floating Offshore Wind Turbine
(Master thesis, 2022)I dyptliggende havområder er muligens flytende vindturbiner den mest kostnadseffektive løsningen for å utnytte potensialet til offshore vindenergi. Behovet for mer bærekraftige energikilder øker, og offshore vind viser ... -
