A systems perspective on maritime autonomy: The Vessel Traffic Service’s contribution to safe coexistence between autonomous and conventional vessels
(Doctoral theses at NTNU;2020:412, Doctoral thesis, 2020)The technology development is a cornerstone of continuously improving the society. Automation has increased efficiency, and during the last decade, digitalisation has been another game changer that has opened for technology ... -
Vico: An entity-component-system based co-simulation framework
(Peer reviewed; Journal article, 2020)This paper introduces a novel co-simulation framework running on the Java Virtual Machine built on a software architecture known as the Entity-Component-System. Popularised by games, this architecture favours composition ... -
Team Collective Intelligence in Dynamically Complex Projects—A Shipbuilding Case
(Peer reviewed; Journal article, 2020)In concurrent engineering projects driven by short delivery times, team performance rests on the team’s capability to quickly and effectively handle different, emergent issues. We conducted an exploratory study of a large, ... -
Co-simulation as a Fundamental Technology for Twin Ships
(Peer reviewed; Journal article, 2020)The concept of digital twins, characterized by the high fidelity with which they mimic their physical counterpart, provide potential benefits for the next generation of advanced ships. It allows analysis of data and ... -
A Cross-Modal Integrated Sensor Fusion System for Fatigue and Awareness Assessment in Demanding Marine Operations
(Doctoral theses at NTNU;2021:34, Doctoral thesis, 2021)The maritime domain is characterized by demanding operations. These operations can be especially complex and dangerous when they require coordination between different maritime vessels and several maritime operators. ... -
Strategic considerations for establishing a large-scale seaweed industry based on fish feed application: A Norwegian case study
(Peer reviewed; Journal article, 2020)Soy protein concentrate (SPC) is a key ingredient in fish feed and most of it originates from Brazil. However, the Brazilian soy industry has reportedly resulted in significant environmental problems including deforestation. ... -
Open Simulation Platform – An Open-Source Project for Maritime System Co-Simulation
(Chapter, 2020)The Open Simulation Platform (OSP) is an open-source industry initiative for co-simulation of maritime equipment, systems and entire ships. With steadily increasing complexity due to the increasing use of software in ship ... -
SpectralSeaNet: spectrogram and convolutional network-based sea state estimation
(Chapter, 2020)Sea State is significant to the operations on the sea. The traditional model-based approaches need lots of knowledge of vessels, which limit the real-world use. This paper proposes a spectrogram-based deep learning model ... -
Multi-ship collision avoidance control strategy in close-quarters situations: a case study of Dover Strait ferry maneuvering
(Chapter, 2020)Multi-ship collision avoidance is challenging in busy waters like the Dover Strait. Usually, ships follow the rules for avoiding collisions which are given by the Convention on the International Regulations for Preventing ... -
Mayday, Mayday, Mayday: Using salivary cortisol to detect distress (and eustress!) in critical incident training
(Peer reviewed; Journal article, 2020)The understanding of stress and its impact on human performance is crucial to mitigate human error in the face of a threat. This is especially the case for critical incidents on a ship bridge, where human error can easily ... -
The combined impact of stochastic and correlated activity durations and design uncertainty on project plans
(Peer reviewed; Journal article, 2020)Most model based studies on project uncertainty investigate a single source of uncertainty, with a dominant focus on stochastic activity durations. However, another major uncertainty facing engineering projects is that of ... -
A Novel Channel and Temporal-wise Attention in Convolutional Networks for Multivariate Time Series Classification
(Peer reviewed; Journal article, 2020)Multivariate time series classification (MTSC) is a fundamental and essential research problem in the domain of time series data mining. Recently deep neural networks emerged as an end-to-end solution for MTSC and achieve ... -
A human-expertise based statistical method for analysis of log data from a commuter ferry
(Chapter, 2020)The proposed method in this paper aims to better understand the log data from the commuter ferry. By the method, the mechanism of how the human expertise operates the ferry can be found, and thus help to establish ship ... -
An effective model-based thruster failure detection method for dynamically positioned ships
(Chapter, 2020)This paper presents an effective model-based thruster failure detection and isolation method for dynamically positioned (DP) offshore surface vessels. A DP vessel is supposed to maintain its position and heading at a ... -
Decarbonization synergies from joint planning of electricity and hydrogen production: A Texas case study
(Peer reviewed; Journal article, 2020)Hydrogen (H2) shows promise as an energy carrier in contributing to emissions reductions from sectors which have been difficult to decarbonize, like industry and transportation. At the same time, flexible H2 production via ... -
Incorporation of ship motion prediction into active heave compensation for offshore crane operation
(Chapter, 2020)Ship motion has significant effects on certain maritime applications like offshore crane operation. In particular, the vertical heave motion is undesired for safe transferring, accurate positioning and subsea installation. ... -
Development of Onboard Decision Supporting System for Ship Docking Operations
(Chapter, 2020)Maritime operations inevitably influenced by the wind, wave, sea currents, or other perturbations at sea. Providing decision support for these operations based on historical and real-time data of ship status is thus of ... -
Cyber Trust in the Norwegian Online Flea Market: An Ethnographic Study on Fraud
(Chapter, 2020)This work-in-progress paper reports an ethnographic study on how cyber trust could be designed to prevent online fraud. A yearlong ethnographic study was conducted with a group of victims who were scammed in online shopping. ... -
Calculating Hourly Cost Rates In Project-Based Industries Part 2: cost management
(Peer reviewed; Journal article, 2020)Hourly cost rates are crucial project costing due to the substantial proportion of labor costs in projects. Yet, there is little published about calculating hourly cost rates, and it is a contentious topic in corporations. ...
