Curious Engineers...

Our 43’ fast Colvic RotorSwing test vessel has recently been used intensively to test and optimize the RotorSwing roll damping equipment. Important issues as minimizing drag and perfecting roll damping characteristics were already completed and our engineers were ready for a new challenge.

We equipped our test vessel with our latest ZeroSpeed stabilizer equipment using the newly designed and advanced underwater drive units with carbon rotors. The challenge was to perfect the damping of the roll motions at anchor or adrift on board of vessels with a short roll period and to avoid jerky motions so common for the cause of seasickness.

But... how do you test this when there are no waves to make the ship roll? And you are extremely curious after the results of your work? Just use the same engineers! With nearly 100 kg Rien used all his weight to make the ship “forced roll” with a remarkable result of 2 x 7 degrees.

After a few excitation rolls we switched the RotorSwing ZeroSpeed to ACTION. The residue roll was only 2 x 1 degrees. A remarkable result of 86 % roll reduction.

Our engineers found their tests succeeded all expectations and with roll reductions of 86 % a remarkable result in ZeroSpeed roll damping. A unique combination of body and brain exercises.
