General information
The Trials & Monitoring department is responsible for the full scale analysis of ship and offshore structures. Dedicated structural engineers form an important part of this team and assure MARIN’s hydro-structural services. Also, in the design phase, or for very specific problems, model tests can be performed in one of the model test facilities at MARIN.

Services & Activities
To assess the structural response of a ship or offshore structure MARIN provides the following services:
To assess the structural response of a ship or offshore structure MARIN provides the following services:
- Full scale measurements
- Model scale experiments
Full scale measurements of structural response is performed by the Trials & Monitoring department.
Model tests to assess structural response are performed by the Offshore department or the Seakeeping department.
Model tests to assess structural response are performed by the Offshore department or the Seakeeping department.
Facilities & Tools
A variety of numerical tools and model tests are used routinely to predict external loads in the design phase. A multi-physics package consisting of FEMAP, ANSYS and LS-DYNA is available to investigate aspects of load-response interaction like hydro-elasticity.
To identify the cause of a problem and to propose a solution our service includes full scale measurements of:

To identify the cause of a problem and to propose a solution our service includes full scale measurements of:
- Local & global stresses by pre-amplified strain gauges and long base strain gauges, respectively
- Ship motions by our in-house developed Marine Quality Kit
- Dynamic pressures due to waves, slamming, propulsion and cargo
- Flow around the the ship
- Noise and vibration levels
- Towing and mooring forces
- Wave heights by wave buoy and wave radar
- Wind and current
- Position, speed and orientation
- Power, torque and revolutions
The following MARIN facilities are used to assess structural response using model tests:
