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] ... -
Sea state optimization of ILT equipment integrated with rigid pipelines on TechnipFMC's reel-lay vessel Deep Energy
(Master thesis, 2022)Denne masteroppgaven omhandler rigid-rørlegging med integrerte ILT-installasjoner på TechnipFMCs «reel-lay» skip Deep Energy på grunt vann. Rigide rørledninger og installasjoner har blitt studert i et bredt og generelt ... -

Sea Water Drilling Fluid Interphase during Riserless Drilling
(Master thesis, 2010)The unique challenges of offshore drilling, unable to be overcome by conventional drilling approaches, have forced the industry to aggressively pursue alternative methods to the “pump and dump” top hole drilling, which ... -
SeaArm - A Subsea Multi-Degree of Freedom Manipulator for Small Observation Class Remotely Operated Vehicles
(Chapter, 2018)This paper presents the design of a novel low cost 4DOF fully electric subsea manipulator for small work class ROVs. The manipulator is designed to work on a wide range of typical observation class ROVs ranging from 5 kg ... -
SeaArm-2 - Fully electric underwater manipulator with integrated end-effector camera
(Chapter, 2021)This paper presents an electrically driven underwater manipulator named SeaArm-2 and considers the kinematic control approach to perform autonomous fixed-base grasping of an object of known size and shape at unknown positions ... -
Seabird Migration Strategies: Flight Budgets, Diel Activity Patterns, and Lunar Influence
(Peer reviewed; Journal article, 2021)Every year, billions of birds undertake extensive migrations between breeding and non-breeding areas, facing challenges that require behavioural adjustments, particularly to flight timing and duration. Such adjustments in ... -
Seabirds as guides for fisheries management: European shag Phalacrocorax aristotelis diet as indicator of saithe Pollachius virens recruitment
(Journal article; Peer reviewed, 2018)In fisheries management, assessing year-class strength and recruitment to commercial stocks is essential, but can be difficult to do for fish species where the young stages are inaccessible to ship-based surveys. This is ... -
Seabirds during Arctic Polar Night: underwater observations from Svalbard archipelago, Norway
(Journal article; Peer reviewed, 2017)Visually-oriented predators, such as seabirds, are highly light dependent, and thus their presence and activity under continuously dark conditions of Arctic polar night pose a number of questions about the strategies and ... -
“Seafarers should be navigating by the stars”: barriers to usability in ship bridge design
(Peer reviewed; Journal article, 2022)Navigating a ship is a complex task that requires close interaction between navigators and technology available on the ship’s bridge. The quality of this interaction depends on human and organisational factors, but also ... -
Seafood export as a relationship-oriented supply network: evidence from Norwegian seafood exporters
(Journal article; Peer reviewed, 2018)Purpose: The purpose of this paper is to examine the role of relationships and networking in the international flow of seafood products through export processes and practices using empirical case examples. Design/methodo ... -
Seakeeping Analysis Comparison Between Viscous And Inviscid CFD
(Master thesis, 2018)With the global community's increased focus on a green and more sustainable environment, stricter demands are being invoked on ship design. Consequently, knowledge on how the vessel responds in a realistic sea-condition ... -
Seakeeping capabilities of sailing cruise and passenger vessels
(Master thesis, 2021)I 2018 annonserte FNs Sjøfartsorganisasjon et mål om å redusere utslipp av drivhusgasser med minst 50% fra 2008 til 2050. For å oppnå dette, er det avgjørende at industrien tar i bruk grønnere propulsjonssystemer. Mens det ... -
Sealant Aging and its Correlation with Facade Reflectance
(Journal article; Peer reviewed, 2014)A highly reflective facade may enhance the durability of sealant joints. This study investigates that reflective facades reduce thermal movement loading to sealant joints due to less fluctuations of surface temperature, ... -
Sealing holes in cellular membranes
(Peer reviewed; Journal article, 2021)The compartmentalization of eukaryotic cells, which is essential for their viability and functions, is ensured by single or double bilayer membranes that separate the cell from the exterior and form boundaries between the ... -
Sealing materials seals for arctic applications
(Master thesis, 2016)This thesis is about exploring the performance of rubber O-ring seals made of materials such as: ELAST-O-LION 101, base HNBR and HNBR 50 CB, under cold temperatures and compressions equal to 10% and 20%. Initially a test ... -
