Marine cybernetics

Cybernetics is the study of how mechanical, electrical, thermodynamic, chemical, and other dynamical systems can be automatically controlled (regulated) in order to make them behave satisfactory according to a control objective under the influence by exogenous disturbances. To develop such technological control systems it is necessary to have a thorough understanding of the physical process, knowledge of modeling and analysis, skills to design feedback control loops, and to implement this knowledge in typically computer-based monitoring and control systems. Cybernetics is to manipulate dynamic systems to make them behave as you want them to. Marine cybernetics, or marine control engineering, is the engineering discipline to design control systems to manipulate marine dynamic processes in order to make them behave according to a specified control objective. Marine control systems are essential for safe and efficient operation of maritime systems, ships and constructions offshore. Such systems have strict requirements to their performance and robustness during changing and challenging conditions. The environmental impact varies largely with respect to how well you design and control these installations. Today, there is high focus on more environmentally robust systems and operation, and central to this development is the marine control systems. While the upside is highly efficient systems with respect to energy utilizations, emissions, profit and safety due to complex repeated operations, the downside is that poorly designed control systems may due to failures result in unwanted consequences. Therefore it is important to understand the forces and physical processes that are in effect, what consequences failures may cause, and design the control systems to safely execute their operational objectives. Marine cybernetics is an area of expertise that applies to most maritime systems - from autonomous vessels in the ocean space to ships and unmanned aerial vehicles supporting offshore operations, from renewable energy sources such as ocean wind farms to diesel-electric and gas-electric propulsion systems, from subsea drilling and marine offshore operations to traditional shipping, from arctic technology to constructions for fisheries and ocean farming. Important areas of research in general: Development of model-based control and observer theories for marine control systems. Development of computer-based decision support systems, automatic fault diagnostics, and monitoring systems. Instrumentation and processing of sensor data, incl. signal fault diagnostics. System simulation for design, analysis, and prototyping of marine control systems. This involves mathematical modeling of marine systems, installations and vessels, sensor and communication systems, electric power systems, propulsion systems, and low-level control systems. Safety analysis, testing, and verification of computer-controlled marine systems. Specific research areas: Dynamic positioning (DP) of ships and offshore vessels in arctic operations. Ice management control and monitoring systems for arctic DP operations Mobile sensor platforms and ice observation systems for operations in arctic regions. Optimal control of electric power production and consumption, minimizing fuel consumption and gas emissions, from marine vessels. Marine cybernetics
