NAVAL SURFACE VESSELs

TRIAL & OPERATIONAL HYDRODYNAMIC services

MARIN, as an independent research institute, can provide answers in any phase of your naval vessel design or operation regarding all hydrodynamic related issues. Our hydrodynamic experience can be used to solve problems of identified risks related to hydrodynamic aspects during designing, delivery, trials, taking into service and operating your naval vessel

NAVAL SURFACE VESSEL TRIAL AND OPERATIONAL HYDRODYNAMIC SERVICES

Our services are offered tailor made according to your specific naval vessel. MARIN has a considerable track record in evaluating performance and behaviour of naval vessels.

Possible services include providing an independent assessment with state of the art tools to derive the speed at contract and EEDI condition compliant with IMO. For manoeuvring aspects MARIN can provide an independent assessment based on prediction tools and trials to check compliance with contract or with IMO.

To assess vibration and noise issues, noise and vibration measurements and analysis can be performed in accordance with ISO. Cavitation observation with dedicated boroscopic cameras through a minimum hull puncture can be done. Analysis and results are given with practical advice for improvement on hull, appendages or propeller.

To address structural fatigue and life time issues MARIN can provide unique measurement techniques for fatigue surveillance. In order to determine the structural lifetime during the operational stage, an unique on board advisory hull monitoring and system (AHMS) can be installed on the ship. Such system can help to determine the reasons for potential deviations of the actual fatigue consumption from design predictions and translates the monitoring data into operational guidance and advice in an easily understandable format.
