  • Marine Vessel and Power Plant System Simulator

    Modern marine electric propulsion vessels have many systems. These interactions and integration aspects are essential when studying a system and subsystem behavior. This is especially important when considering fault scenarios,s harsh weather, and complex marine operations. However, many simulators, including a selection presented here, study the positioning system and the power system separately. This paper proposes a simulator combining the two systems, as an extension to the marine systems simulator MATLAB/Simulink library. The intended use cases and the according design choices are presented. New subsystem models include a power-based electrical bus model and a simplified diesel engine model. Both are validated through the simulation against established models. In addition, established models for generators, electrical storage devices, thrusters, and a mean-value diesel engine model are summarized with rich references. Three case studies illustrate the multi- domain use of the simulator: 1) a semi-submersible drilling rig performing station keeping under environmental disturbances; 2) the same vessel subject to an electrical bus reconfiguration; and 3) a supply vessel with a hybrid power plant.

  • Seasonality of wave prediction skills for supporting marine operations in an offshore wind farm

    Results of a one year hindcast wave simulation using four different modelling approaches are compared against measurements in Liverpool Bay in the Irish Sea, where an offshore wind farm is located. The different modelling approaches include the use of global or mesoscale wind as forcing, the use of different complexity in shallow water parameterizations and different spatial resolution. Comparisons with observations at a buoy located in the offshore windfarm showed a high improvement due to the use of mesoscale wind (from WRF atmospheric model) instead of global fields (From GFS model). Additionally, the increase in resolution and/or the use of more complex shallow water parameterization (4km for WW3 and 250m for SWAN) improved the skills allowing us to obtain of very good results in terms of wave significant height and mean period. No more improvements were found when SWAN used an additional domain with 100m grids. The work shows the high impact of using proper modelling approach in terms of spatial scales in the skills of the wave simulation in an offshore wind farm during a year. Differences in skills between approaches show that the use of high resolution simulations have benefits in the forecasting of meteorological and oceanographic (metocean) conditions for supporting marine operations in the offshore windfarm and, consequently, in a cost-effectively execution of the works involved.

  • Path Planning of Multi-UAS Communication Relay by Decentralized MPC

    When using Autonomous Surface Vehicles (ASV) in marine operations, long distances and/or low power transmissions may severely limit the communication between the ASV and the ground station. One solution to overcome this obstacle is to use a group of small Unmanned Aerial Systems (UAS) to act as relay nodes, in order to provide a user-defined minimum communication capability. To achieve this, we propose a decentralized cooperative multi-agent system using fixed-wing UAS with nonlinear model predictive control, which aims to guarantee a desired signal strength between the ASV and the ground station. The novelty of the presented research resides in the inclusion of the aircraft performance model and the effects of wind, together with the inclusion of the directivity of the antennas. Experimental results of the proposed method are obtained through simulations.

  • Network of heterogeneous autonomous vehicles for marine research and management

    In April 2016, NTNU, FFI, Kongsberg Seatex, LSTS and Maritime Robotics set up an experiment to explore their capability to combine the research vessel Gunnerus, the AUV Hugin, the UAV X8 and the USV Mariner in a network of heterogeneous unmanned vehicles. Communication, manoeuvring, onboard processing and operational complexity are essential components in such networks. To provide communication the MBR broadband radio system was implemented. To show the capabilities of the system proposed, a scenario with seabed mapping and target recognition was defined. The experiment made it apparent that these networks has the potential of significantly saving cost for data collection in marine research and management by reducing ship time. To fully unlock the potential of networks of heterogeneous unmanned vehicles, the missions of each vehicle need to be more integrated.

  • Underwater vehicles for environmental management in coastal areas

    Methods for using underwater vehicles for mapping and monitoring are developed continuously. These methods developed must be accurate, quantitative and repeatable while being as cost effective as possible. In 2011, 2012, 2013 and 2014 The Norwegian University of Science and Technology (NTNU) Applied Underwater Robotics Laboratory completed surveys in the Trondheim Fjord area. During these surveys methods relevant for addressing several of these challenges have been tested. We have tested Synthetic Aperture Sonar for establishing baselines for marine habitats and littering. In the sonar data cold-water coral habitats gave a significant signal. These observations were confirmed by video and hyperspectral imaging. We have also revisited the same areas and demonstrated the potential to detect changes. During our campaigns the sonar data has also been verified by ROV video and sampling. A dumping area in the fjord was mapped by the AUV mounted SAS and on a subsequent cruise the ROV was deployed for video survey, stereo photos and sediment sampling. Stereo models may prove an important tool where millimeter resolution and precision is attainable. Based on the experimental work presented in this paper, a proposal for underwater vehicles in environmental management of coastal areas is described.

  • Predicting sea ice conditions for marine operations in ice-covered waters

    Marine operations in ice-covered waters require reliable and timely information about the sea ice conditions. The Canadian Ice Service produces and distributes the ice information to mariners operating in the Canadian water in the form of daily ice charts. Unfortunately, however, due to the time difference between the production and the use of the ice charts, the ice information is always out of date, which endangers the safety of marine operations. To efficiently overcome this problem, a reliable model for predicting the sea ice conditions (concentrations) over time is developed. Inspecting the ice charts for the period 1987 to 1998 showed that the sea ice conditions change according to a regular pattern to some extent. Therefore, a neutral network function approximation system could model, and hence predict, these changes efficiently when trained using multiple-year ice concentrations readings. The data used in training the neural network are extracted from the ice charts for the Gulf of St. Lawrence in eastern Canada. The input to the network is a vector which represents the current ice concentrations over a test area containing 40 points. The input vector is mapped to an output vector that gives the predicted ice concentrations.

  • Cooperative systems for marine operations using actor-network design: A discussion

    After discussing the roles of marine engineers and interaction designers from computer science (CS)/information systems (IS), I investigate issues with the aim of promoting better cooperative systems for maritime industries. As part of my research project, I have observed marine operations and interviewed bridge operators, captains, and crewmembers, as well as engine engineers in their workplace, in order to investigate how cooperative work occurs in current marine operational systems. Against the background of computer- supported cooperative work (CSCW), I look into how to improve systems to support safety-critical operations for offshore services at sea. Most safety- critical operations occur as part of cooperative operations and interactions between operators and systems. Engineers and interaction designers should cooperate to design cooperative systems with users in the early stages. However, there is not a common understanding between engineers and interaction designers regarding the meaning of cooperative work. In order to improve computer systems to support marine cooperative work, a new understanding of marine technology is necessary where design needs are met through the integration of engineering design, CS/IS theoretical thinking, and work practices. Human operators, systems, and materials used in workspaces are actors deeply lived in work environments; hence, I discuss a means of adopting Bannon's concept of human actors toward the development of an actor-network design of cooperative systems.

  • Nonlinear observer with time-varying gains for inertial navigation aided by satellite reference systems in dynamic positioning

    The measurement quality of Global Navigation Satellites Systems (GNSS) during marine operations will vary over time. Inherently, GNSS quality changes should be handled when GNSS is utilized as aid in inertial navigation systems. In this paper we present an observer for estimating position, velocity and attitude with time-varying gains for high-performance sensor fusion based on GNSS quality and other quality indicators. The origin of the error dynamics is proven to be uniformly semiglobal exponentially stable. The concept is illustrated by simulating a vessel operating in dynamic positioning with GNSS and inertial sensors.

  • Sea state estimation using model-scale DP measurements

    Complex marine operations are moving further from shore, into deeper waters, and harsher environments. The operating hours of a vessel are weather dependent, and good knowledge of the prevailing weather conditions may ensure cost-efficient and safe operations. This paper considers the estimation of the peak wave frequency of the on-site sea state based on the vessel's motion in waves. A sea state can be described by significant wave height, peak wave frequency, wave direction, and often wind speed and direction are added as well. The signal-based algorithm presented in this paper is based on Fourier transforms of the vessel response in heave, roll and pitch. The measurements are used directly to obtain an estimate of the peak frequency of the waves. Experimental results from model-scale offshore ship runs at the Marine Cybernetics Laboratory (MCLab) at NTNU demonstrate the performance of the proposed sea state estimation algorithm.
