AMADEA - Adaptable Maritime Decision Support Architecture
Kyllingstad, Lars Tandle; Skjong, Stian; Ladstein, Jarle; Haugen, Joakim (SINTEF rapport;2023:00409 A, Research report, 2023-03-06)Here, we present a reference model for maritime decision support systems. We establish a common terminology for the components and structure of such systems, describe a number of general-purpose components that can be ... -
Data-driven sea state estimation for vessels using multi-domain features from motion responses
Han, Peihua; Li, Guoyuan; Skjong, Stian; Wu, Baiheng; Zhang, Houxiang (Chapter; Peer reviewed, 2021)Situation awareness is of great importance for autonomous ships. One key aspect is to estimate the sea state in a real-time manner. Considering the ship as a large wave buoy, the sea state can be estimated from motion ... -
Directional wave spectrum estimation with ship motion responses using adversarial networks
Han, Peihua; Li, Guoyuan; Skjong, Stian; Zhang, Houxiang (Peer reviewed; Journal article, 2022)The external environmental conditions around a vessel are essential for efficient and safe ship operation, among which the sea state is of key importance. Considering the ship as a large wave buoy, the sea state can be ... -
Distributed Co-Simulation of Maritime Systems and Operations
Sadjina, Severin Simon; Kyllingstad, Lars Tandle; Rindarøy, Martin; Skjong, Stian; Æsøy, Vilmar; Pedersen, Eilif (ASME digital collection;OMAE-17-1037, Journal article; Peer reviewed, 2018-05)Here, we present the concept of an open virtual prototyping framework (VPF) for maritime systems and operations that enables its users to develop reusable component or subsystem models, and combine them in full-system ... -
A distributed object-oriented simulator framework for marine power plants with weak power grids
Skjong, Stian; Pedersen, Eilif (Peer reviewed; Journal article, 2022)In this work, we discuss and demonstrate how multi-engine marine power plants with weak power grids efficiently can be set up and simulated in a distributed co-simulation framework. To facilitate configuration switching ... -
Energy conservation and power bonds in co-simulations: non-iterative adaptive step size control and error estimation
Sadjina, Severin Simon; Kyllingstad, Lars Tandle; Skjong, Stian; Pedersen, Eilif (Journal article; Peer reviewed, 2017-07)Here, we study the flow of energy between coupled simulators in a co-simulation environment using the concept of power bonds. We introduce energy residuals which are a direct expression of the coupling errors and, hence, ... -
Lumped, constrained cable modeling with explicit state-space formulation using an elastic version of Baumgarte stabilization
Skjong, Stian; Reite, Karl-Johan; Aarsæther, Karl Gunnar (Peer reviewed; Journal article, 2021)This paper presents a modeling approach for efficient simulation of slender structures, such as wires, cables and ropes. Lumped structural elements are connected using constraints. These are solved explicitly, using an ... -
On the numerical stability in dynamical distributed simulations
Skjong, Stian; Pedersen, Eilif (Journal article; Peer reviewed, 2019-09)This work takes aim at studying numerical stability in distributed simulations through dynamic stabilityand stability criteria for explicit solvers. This is done by studying outer stability limits, for example stabilityconditions ... -
System-level modeling of marine power plant with PEMFC system and battery
Malekibagherabadi, Kamyar; Skjong, Stian; Bruinsma, Jogchum; Pedersen, Eilif (Peer reviewed; Journal article, 2022)This article presents a model of a marine power plant with hybrid power sources consisting of Proton Exchange Membrane Fuel Cells (PEMFCs) and batteries. The primary objective is to develop a system-level fidelity model ... -
An Uncertainty-aware Hybrid Approach for Sea State Estimation Using Ship Motion Responses
Han, Peihua; Li, Guoyuan; Cheng, Xu; Skjong, Stian; Zhang, Houxiang (Peer reviewed; Journal article, 2021)Situation awareness is essential for autonomous ships. One key aspect is to estimate the sea state in a real-time manner. Considering the ship as a large wave buoy, the sea state can be estimated from motion responses ... -
