SIMULATE, TEST, EXPERIENCE
our fundamentals
To challenge the uncontrollable wind and waves we need facilities to recreate and simulate natural conditions to test ships and operations. Since we do not only recreate but also challenge these elements we need reliable tools and software enabling us to manage the dynamic sea. Using our facilities and tools we make ships and operations safer, cleaner and smarter.
CLEANER, SAFER AND SMARTER
Our track record in research and innovative concept development would not be possible without our facilities and tools. Since the start we have made thousands of ships and operations around the world safer, faster, more efficient and greener. Aiming to bridge the gap between design and operation we are involved in the entire lifecycle of the ship, from the initial concept development to design, construction and subsequently to the final operation. This allows us to continuously assess and improve our research.
We have a complete range of model test facilities, software tools, simulators, numerical facilities and measurement techniques to test, simulate and monitor ships and operations including the human factor. The unique combination and synergy of these facilities and tools enable us to achieve reliable predictions of the performance in the design phases, but also to improve and ensure the optimal operational use of the ship or structure.

NUMERICAL FACILITIES
For over 15 years we have been using computational clusters to assist with time consuming numerical studies. Over the years these clusters have continued to grow in size and capabilities. Since MARCLUS4 was introduced in 2014 these computational clusters combined with our in-house software have been seen as a numerical facility for a broad range of simulations, such as Computational Fluid Dynamics (CFD) using our ReFRESCO code, but also time-domain simulations using our XMF framework.
MARCLUS4
This BULL cluster was purchased in 2014. In total the system has 4360 Intel Xeon cores and 18TB RAM available for batch computations with a central storage of 550 TB.

MARCLUS5
Our latest Atos-Bull cluster, called Marclus5, was purchased in 2018. It is factor 4 faster than MARCLUS 4. It has 9000 CPU cores and 50 TB RAM available for batch computations with a central storage of 2 PB.

A SELECTION OF MEASUREMENT TECHNIQUES
Our clients require detailed measurements of both the operation’s performance and its circumstances. That is why we are continuously developing and implementing new experimental techniques.
HIGH SPEED VIDEO
Many processes occur much faster than can be observed by the eye, such as the growth and collapse of cavitation on a propeller or the impact of a wave on a structure. When we use high-speed video we can watch such a process slowed down for careful study. At MARIN, high-speed video is applied using frame rates that are up to 200 higher than normal video. The high frame rate ensures that the details of the process are captured.

PARTICLE IMAGE VELOCIMETRY (PIV)
Particle Image Velocimetry is a method to determine the velocities in a fluid. The flow measurement with PIV is based on the measurements of the displacement (∆x) of a particle in a target plane between two successive light pulses with time delay (∆t). The flow is seeded with particles and the target plane is illuminated with a light sheet. The particle positions are recorded by two special digital cameras. Special image processing software analyses the movements of the group of particles in subsections of the PIV-image using correlation techniques. By using two cameras in a stereoscopic arrangement the instantaneous three velocity components are derived in the measuring plane.

MULTI COMPONENT TRANSDUCERS FOR PROPELLER LOADS
The 6 component transducers can be used for measuring the omnidirectional propeller loads, while 5 component transducer can be used for measuring 2 blade forces and 3 blade moments. Combined with time synchronised high speed video recordings this can provide an insight in dynamic propeller loading phenomena.
