General information
From a hydrodynamic perspective, submarines might be some of the most complex ships today. Due to stealth requirements, strict limitations are posed regarding the radiated noise. Furthermore, tactical and safety requirements dictate high levels of controllability in all six degrees of freedom. Sailing submerged at full speed underneath ice or close to the bottom requires very accurate depth control, while evasive manoeuvres require swift reaction to steering action and small turning diameters.

Services & Activities
MARIN is involved in hull form optimisation, noise & vibration and manoeuvring studies for submarines. Extensive use of CFD is made during the optimisation of the hull form, see here.

Investigations in the seakeeping performance for submerged (snorkelling/snorting) as well as surfaced condition and verification of the stringent demands on the controllability can be examined using our tools or basins. Examples include the steering ability and ship & platform motions for the various degrees of freedom using simulations or model tests.

The Nautical Centre MSCN offers training of the crew and the simulation of special situations and is actively involved in the development of submarine simulators.

The Trials & Monitoring Department is involved in in-service performance monitoring, cavitation observation, noise & vibration measurements and measures loads & responses.

Facilities & Tools
Submarines are tested in the following MARIN facilities:

Resistance and propulsion, Captive/PMM manoeuvring tests
Cavitation, noise and erosion observation, steady oblique motion and flooding tests
Seakeeping and manoeuvring tests using free sailing models and waves from arbitrary directions
Seakeeping and manoeuvring tests in shallow water
PMM tests
Similar as in the Seakeeping and Manoeuvring Basin, for variable water depths, current and waves from arbitrary directions

Submarine behaviour can most notably be evaluated by the RAPID, PARNASSOS, ReFRESCO, SUBSIM, SUBMAR, SAMSON and FREDYN tools.

For information on these and other software tools relevant for submarines, please see:

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.
