Patrol vessels
General information
Patrol vessels have a diplacement of approximately 700 tons that can patrol the waters of the Exclusive Economic Zone for an extended period of time. Usually a patrol vessel is lightly armed and equipped with a helicopter deck and several RIBS which enhances their patrolling capabilities. Task include fishery and environmental protection, assistance in operations, search and rescue and limited towing and fire fighting.

Services & Activities
MARIN is involved in the development of the hull design, the power optimisation and the cavitation, noise erosion observation. Special interest is payed at items like transit fuel actieradius, topspeed, noise and vibrations and the allignment of appendages.

Since these vessels stay out at sea in all weather conditions, survivability and workability on board of these vessels is very important. Research can for example be related to the seakeeping performance, survivabiltiy in extreme weather, sustained speed in waves and anti roll systems (i.e. fin stabilisers, bilge keels, anti roll tanks). MARIn can help you on topics such as howto controll the motions for example for helicopter landing operations or in order to prevent see sickness of the crew.

Since Patrol vessels always have to sail into the harbour on their own power in often relatively small harbours the manoeuvring aspects of a patrol vessels are important. MARIN verifies the stringent demand on the manoeuvrability.

The Trials & Monitoring Department is involved in full-scale measurements of the ship

Facilities & Tools
Patrol vessels are tested in the following MARIN facilities:

For patrol vessels computer calculation and simulation tools are available to predict their behaviour in early design: (SHIPMO, FREDYN, GULLIVER and SURSIM for MARIN internal use only)

Software Sales
Some software tools are available for commercial use outside MARIN. A complete overview of these software tools for sale can be found under Software Sales.
