A design methodology for resilience in fleets for service operations
Pettersen, Sigurd Solheim; Asbjørnslett, Bjørn Egil (Chapter, 2016)In this paper, we present a new conceptual design methodology for increasing the resilience in complex operations involving a fleet of ships. The objective of the methodology is to support design decisions to reduce ... -
A Method for Detecting Near-Misses from AIS Data
Gjøsæter, Håvard (Master thesis, 2019)Konsekvensene av maritime ulykker kan være enorme med hensyn til tap av liv, økonomiske tap og miljøskader. Derfor har forbedring av sikkerheten til sjøs vært et fokus i mange år, og det har vært utført ulike maritime ... -
A New Small-Scale LNG Distribution and Bunkering Facility: - An Approach to Risk Based Design and Verification
Steine, Caroline Mortmannsgård Gams (Master thesis, 2013)LNG is the preferred solution to meet environmental requirement and a great market growth is expected within few years. Lack of suitable infrastructure, regulation and bunkering practices poses challenges to the industry, ... -
A Simulation-Based Optimization Model for Fleet Sizing and Fleet Composition of a Well-Boat Fleet
Klungseth, Joachim (Master thesis, 2020)Den norske oppdrettsindustrien har hatt en fabelaktig vekst de siste 20 årene og denne veksten er forventet å fortsett i flere tiår framover. Dette vil medføre et stort behov for nye brønnbåter, samt verktøy for å effektivisere ... -
A simulation-based ship design methodology for evaluating susceptibility to weather-induced delays during marine operations
Sandvik, Endre; Gutsch, Martin; Asbjørnslett, Bjørn Egil (Journal article; Peer reviewed, 2018)In this paper, we present and test a discrete-event simulation approach for evaluating the inherent susceptibility to weather-induced delays during marine operations as a consequence of limitations in vessel response ... -
A Study of Satellite AIS Data and the Global Ship Traffic Through the Singapore Strait
Smestad, Bjørnar Brende (Master thesis, 2015)This thesis investigates the quality and utility of Automatic Identification System (AIS) data. AIS is primarily used as a tracking system for ships, but with the launch of satellites to collect these data new and previously ... -
A Study of the Operational Patterns of LNG Carriers from AIS Data
Axelsen, Jørgen Jensen (Master thesis, 2018)This thesis investigates the operational patterns of LNG carriers from Automatic Identification System (AIS) Data. AIS was created for vessels as a safety-enhancing supplement to the radar, and over the last decade satellites ... -
Addressing the Coast Guard Fleet Mix Problem From a Value-Centric Perspective
Buland, Marius Oddmund (Master thesis, 2017)The decision to acquire a fleet of coast guard vessels is typically irreversible and of longterm impact. Once vessels are bought and built, they typically remain within the fleet for a few decades. This emphasizes the ... -
Agility by Design: A Real Option Approach to Identify and Value Time-efficient Changes in Marine Systems
Christensen, Carsten (Master thesis, 2017)Quickly adapting to changing market conditions is crucial for every firm, especially in volatile and capital intensive markets. These are two characteristics of the maritime industry. Incorporating flexibility in design ... -
An approach towards the design of robust arctic maritime transport systems
Bergström, Martin Vilhelm; Ehlers, Sören; Erikstad, Stein Ove (Maritime-Port Technology and Development;, Book; Chapter, 2014)This paper describes a simulation-based approach towards the design of robust arctic maritime transport systems that are adaptable to uncertain future ice conditions. It makes it possible to simulate the performance of ... -
An Environmental Life Cycle Assessment of LNG and HFO as Marine Fuels
Laugen, Lars (Master thesis, 2013)The maritime transportation industry will face harder requirements from the international community when it comes to environmental issues. The introduction of Emission Control Areas (ECAs) has forced shipowners to rethink ... -
An Exploratory Study of a Wet Bulk Platform Supply Vessel using Operations Research - Single-Vessel Scheduling with Bulk Loads and Mud-Cleaning Process Plant
Resell, Rebekka (Master thesis, 2017)In order to deal with an increased demand for wet bulk on the offshore installations on the Norwegian continental shelf, a new system for handling wet bulk logistics is investigated in this thesis. The reason for the ... -
An Investigation of Methods and Value of Information in Routing of Priority-Based Operations - Using a Rule-Based Routing Method Tested with Discrete Event Simulation
Nygård, Carina (Master thesis, 2020)Operasjoner i kystsonen beveger seg mot mer eksponerte farvann. Et problem kan derfor oppstå når operasjoner i eksponerte og skjermede farvann har til hensikt å bruke det samme fartøyet. Fasiliteter, slik som for eksempel ... -
An Investigation of Offshore Wind Installation Strategies - A Discrete-Event Simulation Model Used to Investigate Installation Vessel Operability
Vartdal, Johanne Tomine (Master thesis, 2017)The offshore wind industry has experienced an immense growth during the past years, but one of the main limitations for development is the high installation costs which may account for almost 20 % of total life cycle costs. ... -
