Optimal Actuator Placement for Real-Time Hybrid Model Testing Using Cable-Driven Parallel Robots
(Peer reviewed; Journal article, 2021)In real-time hybrid model testing, complex ocean structures are emulated by fusing numerical modelling with traditional hydrodynamic model testing. This is done by partitioning the ocean structure under consideration into ... -
Optimal configuration of supply logistics for remote oil and gas fields
(Master thesis, 2013)The objective of this thesis has been to compare alternatives to improve the supply service for remote locations offshore. First the alternative of running a conventional supply service has been assessed, where the platform ... -
Optimal configuration problem identification of electrical power cable in tidal turbine farm via traveling salesman problem modeling approach
(Peer reviewed; Journal article, 2019)Electrical power cables in tidal turbine farms contribute a significant share to capital expenditure (CAPEX). As a result, the routing of electrical power cables connecting turbines to cable collector hubs must be designed ... -
An Optimal Energy Management System for Marine Hybrid Power Systems
(Chapter, 2021)This paper proposes an optimal control strategy for the energy management system (EMS) of marine hybrid power systems with the objective of reducing operational expenses (OPEX) and environmental emissions. Here, the OPEX ... -
Optimal Force Allocation for Overconstrained Cable-Driven Parallel Robots: Continuously Differentiable Solutions With Assessment of Computational Efficiency
(Peer reviewed; Journal article, 2020)In this article, we present a novel method for force allocation for overconstrained cable-driven parallel robot setups that guarantees continuously differentiable cable forces and allows for small penalized errors in the ... -

(Master thesis, 2015)This report present a new solution method to analyze usage of hub-vessels in upstream logistics for remote fields. The objective in this thesis is to analyze which parameters that affect the logistics chain for remote ... -
Optimal location of ammonia replenishment to support the Northeast Asia - US Pure Car Carrier green corridor
(Master thesis, 2023)Skip er regnet som den mest kostnadseffektive metoden for frakt av varer rundt om i verden. Omtrent 80% av den globale verdenshandelen foregår i dag på sjøen og denne formen for transport er i stor grad drevet på tungolje, ... -
Optimal Location of Energy Replenishment Stations for Zero-Emission Vessels
(Master thesis, 2022)For å muliggjøre det grønne skiftet innen sjøtransport, så må nullutslippsenergibærere tas i bruk av industrien. En betydelig utfordring for noen av nullutslippsenergibærerne (f.eks. hydrogen) er energilagringskapasitet. ... -
Optimal Online Configuration and Load-Sharing in a Redundant Electric Power System for an Offshore Vessel Using Mixed Integer Linear Programming
(Chapter, 2018)This paper proposes several schemes for optimal online configuration and load sharing for a shipboard power system of a typical offshore vessel, having a number of varying capacity gensets. Different methods are presented ... -
Optimal path-planning on a bio-inspired neural network guidance model for autonomous surface vessels
(Master thesis, 2020)Planlegging av en trygg og kollisjonsfri bane er avgjørende når graden av autonomi i skip øker. Det gjøres med utgangspunkt i en modell av omgivelsene, som her har vært i form av et bio-inspirert nevralt nettverk. En ... -
