Advanced Friction Testing

Design frictional interfaces in line with:

2. Corrosion as well as wear & tear

3. Design temperatures, up to arctic conditions

Test with short lead time for recurring applications

Validation Against Full Scale Measurements

To check whether small scale results are representative for full scale situation.

Identical material & conditions. 8 different counter-surfaces. 8 different friction values.

At low temperatures friction can change significantly depending on the polymer material composition.

Stiffness can vary by factor 10 for your range of design temperatures.

Avoiding assuming friction values in your project but validate them. For example of slings against clamps:

Test within days according to DNV validated procedure for many available material combinations.

Polymers are never isotropic. Sometimes even incompressible. This can have large implications.

Shape matters. Validate strength & stiffness according to procedure developed together by TWD & DNV.

Dampers and seals need to be one-time-right. Catalog and small scale tests are often inaccurate.

Achieve stress reductions up to 20% at interface by properly accounting for behavior of polymer supports.

Use a TWD developed coating which optimizes safety for your operations

Replace expensive steel elements with recyclable filler elements and load test them.

Replace temporary steel supports of equipment by cheap and light EPS.

Avoid inflow of sand on spudcans and mud-mats using geotextile (or mitigate other risks).

Avoid damage to soft slings and optimize interface design by prototyping and testing.

Use TWDs extensive experience with handling a wide variety of coatings.

Transit and installation conditions and corresponding contact pressures and shear loads significantly increased.

Simulate design conditions and validate damage according to ISO-4628. Optimize designs based on results.

Difference in lifetime between loaded and not loaded interfaces to be avoided.

Especially in linear systems grease can collect dirt or cause stick-slip.

Only procuring bearings is insufficient, system understanding is required

Due to a smaller true area of contact the resistance reduces significantly.

Determine optimal clamp design by testing to maximize resistance and avoid sudden failure.

Check on permanent damage due to operational and accidental loads from clamp.

Design codes require 2.5 lifting factor due to suction developing at the mud-mat soil interface.

Accurately measuring type and amount of suction relief on small scale.

Applying innovative mitigations (holes, textiles & layering) reduces suction up to 200%.

Softwood performs better than hardwood in some contact pressure ranges.
Using thin sheets of softwood instead of hardwood can cause large cost benefits.

Softwood performs better than hardwood in some contact pressure ranges.
Using thin sheets of softwood instead of hardwood can cause large cost benefits.

Using wood for seafastening is more cost efficient, reduces stresses at interface and increases flexibility.

Determine correct shim material which avoids coating damage and is highly wear resistant.

Corrosion impacts friction pads with more than 30%. This is unsafe and replacement is costly.
TWD verified cleaning and maintenance procedures restoring the original frictional capacity.
