Simulation and prototyping

Real-time simulator. Operation of a 75 000 tdw bulkship in Akselsundet, Spitsbergen. Automatic Control and Data Acquisition System (ACADAS) - a real-time control system based on Rapid Control Prototyping techniques. Design of a joystick control system for FerryCat. A project with Rolls-Royce Marine AS and Fjellstrand. Monitoring of motions and structural stress - prototype system. Visualisation of an UAV takeoff.

MARINTEK's activities can be divided into two major fields: 

Simulation

• Simulation Architecture and Simulator Design. MARINTEK uses the industrial simulation standard High Level Architecture (HLA), IEEE Standard 1516 to integrate hydrodynamic, cybernetics and structural software with COTS components for visualisation and human machine interface. This platform is now widely used in industries and navies (NATO standard) and MARINTEK participate together with The Royal Norwegian Navy in several Specialist Teams in NATO within ship manoeuvrability and simulation technologies.
• Scenario Based Simulations. Simulations can be performed in real-time (human-in-the-loop) or as fast as possible. Examples are multiple simulations of failures and different environmental conditions (wind, current and waves). Examples from earlier projects are ship handling in congested waters and docking of ships
• Simulation Environment. MARINTEK offers a Simulation Environment. The synthetic environment consists of numerical ship models, control algorithms and motion sensors models connected together using the HLA standard. Visualisation and evaluation of ships motion from model tests, full scale measurements and simulations are possible in the same environment. Third part vendors, like control system vendors can use the Simulation Environment to develop, validate and verify their control system design at an early stage. The simulation environment can also be used for developing material for presentations. Examples are motion of ships, air vehicles, underwater vehicles and visualisation of complex operations.
• FME(C)A and Performance Analysis. In order to evaluate system performance and effects of system failures, a set of predefined scenarios or simulations can be performed as fast as possible. The results and reports are more or less generated automatically.

Prototyping

• Rapid Control Prototyping. MARINTEK uses the latest technology in control system design. Control software is developed graphically in MATLAB/Simulink environment and C-code is automatically generated using the Real Time Workshop and Embedded Coder toolboxes. All the above products are trademarks of MathWorks Inc. The control software is either interfaced to the simulator or downloaded into the target system. Combinations of both software and hardware-in-the-loop simulations are useful in control system design. This technology has been used to develop a joystick control system for a double-ended passenger ferry denoted FerryCat.
• System Design. MARINTEK has experience in system design and system integration. A prototype of new structural stress and motion system has been developed by integrating numerical design tools from desktop to an onboard system. The system provides an active guidance to the operator with respect to predicted responses.
• Instrumentation, Control and Data Acquisition. The Simulation and Prototyping Group also provides services for instrumentation, control and data acquisition of ship motions. A real-time control system denoted Automatic Control and Data Acquisition System (ACADAS) has been develop for the hydrodynamic laboratories. The ACADAS includes course-keeping, track-keeping and ride control algorithms for most conventional ships.
