Torque Transfer System for offshore Turret Production System
(Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2020-06)Turret production systems allow Floating Production Storage and Offloading (FPSO) units to weathervane and thus significantly reduce environmental loads on the mooring system. There are several different variants of such ... -
Torsional loaded towhead foundation
(Master thesis, 2022)Foundations are made to withstand and transfer loads to the soil layer beneath. Soil bearing capacity is defined as the soil's ability to support all acting loads. It is preferable to have a foundation with pure vertical ... -
Towards a risk-based decision support, parameterization of hindcast data to an offshore installation duration in offshore wind farm planning phase
(Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2021-01)For the planning stage in any wind farm development, there are many concepts and locations to be analyzed at the point of cost, schedule, and project shareholders. Especially, the marine operation requires careful planning ... -
Trajectory Envelope of a Subsea Shuttle Tanker Hovering in Stochastic Ocean Current - Model Development and Tuning
(Peer reviewed; Journal article, 2022)A subsea shuttle tanker (SST) concept for liquid carbon dioxide transportation was recently proposed to support studies evaluating the ultra-efficient underwater cargo submarine concept. One important topic is the position ... -
Transitioning towards renewable energy and sustainable storage solutions at remote communities in the Arctic, Case study of Flatey, Iceland
(Peer reviewed; Journal article, 2023)The need for transitioning towards renwable energy and sustainable storage solutions is particularly challenging for remote communities in the Arctic, located far away from the electricity grid. This paper explores the ... -
Trawl gear interaction with subsea pipelines
(Masteroppgave/UIS-TN-IKM/2012;, Master thesis, 2012)This master thesis is written at the University of Stavanger in collaboration with IKM Ocean Design. The presence of both the fishing industry together with the oil and gas industry offshore results in development of ... -
