Vard Marine employs computational fluid dynamics (CFD) to simulate marine conditions and predict the flow of air and water around a ship, bringing highly advanced software, tried and tested models and our teams’ exceptional know-how to the table.
The result is the resolution of mission-critical problems involving fluid flows – such as hull resistance, equipment placement or flight deck turbulence – that can make the difference between the safe and successful operation of a vessel, and costly re-work if issues emerge after construction
VARD MARINE’S CFD PHILOSOPHY
VARD’s motto – Built on trust – is more than just words. We earn the trust of our clients by bringing only well-researched methods and models to the table. We’ve validated our CFD models time and again through model tests and full-scale ship trials. All in all, our rigorous quality assurance program is second to none.
Yet we never lose sight of resource and scheduling requirements. We do what it takes to deliver high quality services tailored to both the needs and the constraints of our clients.
The client advantage
You’ll get meaningful, reliable results based on proven methodologies and techniques finely tuned through years of real-world experience.
These results are produced by a team with an unbeatable combination of theoretical knowledge, practical experience and determination to stay at the forefront of emerging trends.
In fact, our clients praise our reliability. They comment on our helpful communication. They feel their input is valued. Above all, they’re impressed by the quality of the CFD service and product.
We trust you will be too.
HOW WE USE CFD
The main tool we use to work our CFD magic is SIEMENS Star-CCM+.
Some of our most common simulations investigate:
- ship hull resistance and powering calculations:
- at full scale
- including sinkage and trim at speed
- including hull-propeller interaction
- hull form optimization and appendage alignment
- bubble sweep-down interference with gondola or sonar equipment
- airflow, including exhaust gas concentration/temperature and helideck turbulence.
We use both in-house and third party high-performance clusters to guarantee we can meet even the most demanding simulation or tightest schedule.
WE DON’T STOP THERE
Some additional areas that benefit from CFD analysis include:
- manoeuvring analysis
- wind and current coefficients for dynamic positioning analysis
- airflow in critical spaces (eg. machinery space)
- unique problems, like
- circulation and sedimentation in tanks containing a non-Newtonian fluid
- LNG gas release
- moonpool sloshing and run-up
- tank sloshing
