MARIN is an independent service provider in hydrodynamic and nautical research and development, whose know-how and experience is made available for Concept Development, Design Support, Operations Support and Tool Development. MARIN’s customers include governments, authorities, commercial ship builders, fleet owners and naval architects internationally. The core asset of MARIN is its staff, in total over 350 employees, from researchers to engineers.
With advanced mathematical models different aspects of the sailing behaviour of ships and offshore structures can be investigated and optimized via computations. For validation and or investigating special model tests are used. Full scale measurements are performed to validate predictions or to analyse specific topics in full scale. Real time simulation is applied for training purposes and for investigating sea keeping behaviour and manoeuvrability in critical conditions.
More specific MARIN provides (1) consultancy in concept design, business case calculations, operational performance of ships, inland ships and seagoing ships. (2) Prediction, optimization and model testing focused on minimizing the resistance and propulsion power of ships and on operational performance of offshore (wind) structures. (3) Assessing, improving and or modelling manoeuvring behaviour of ships. (4) Simulations of (inland) ship manoeuvring in critical conditions.
Performance assesment of Wind Turbine Installation Vessels
A Wind Turbine Installation Vessel is complex in operation. It transforms from a vessel to a platform and vice versa. MARIN provides assistance in determining the operational performance from a hydrodynamic point of view, in design phase and in daily operations. Our services consist of: Propulsion optimization, Predicting vessel motions and Crew comfort, Jack-up leg impact load analysis, DP station keeping accuracy analysis, Operability analysis, Training of crews and Tools to support on board daily operations.
Speed Power Prediction
Our DESP-tool predicts the speed-power relation in an early design stage. The tool is used in combination with model test data of similar ships in order to improve the prediction. In this way different alternatives can be compared. Confined water effects can be included.Next steps: optimizing the hull shape to reduce wave making resistance and to improve the stern configuration. Here more complex CFD computations are used.
Operational Analysis applying voyage simulations
The ship route simulation tool GULLIVER is available for so-called shiproute simulations. This allows comparing fuel consumption of different designs in different conditions over a complete voyage. In sea going situations relevant wind and wave data is collected. The resulting performance assessments provide insight in for example operational windows, service reliability, and comfort levels for crew/passengers.
Integrated aftship-propulsion design, assessment
Pushboats, tugs and workboats have a complex operating profile. The vessels have to cope with different situations and conditions. Balancing powering performance and maneuvring performance is an important aspect of the design. Z-drives versus a conventional propeller/nozzle/rudder configuration. How is the vessel (-design) performing in critical conditions and during a trip. MARIN has different tools to predict performance and compare alternatives.
Ships Power and Energy Concept (SPEC)
The SPEC method is developed to define optimal power systems for ships with clean energy. Given the operational requirements a database is used with different energy sources, its equipment and storage requirements and a set of technical and economical criteria. The output is a ranked selection of solutions.
Development of hull design, hull design optimisation
In an early design stage, MARIN advises about the development of hull lines. MARIN has several CFD tools available. Depending om the topic the most appropriate tool is used (a balance between cost and effectiveness). These tools can be applied in combination with optimization techniques to cope with more variables. This enables us to analyse and visualize the trends and dependencies, the pro's and con's of the different options are identified and the most effective solution(s) selected.
