Wave Making Resistance – Best Example.

Excerpts from the IMarEST Condition Based Maintenance Conference.

While the 6th condition based maintenance conference came to an end, we captured some fantastic presentations from various speakers and here is one interesting aspect where Mr Amitava Talukdar, who heads the Energy efficiency project under Viswa Lab, presented on wave making resistance.

We all know what is a wave making resistance when it comes to a ship’s performance.  But here are our views where a wave making resistance was best explained during the condition based maintenance conference.

A ship’s’ total resistance = Air resistance + Wave making resistance + Viscous resistance

Wave making resistance is one where the power from the ship’s engines are wasted in creating waves.

Mr Amit, further explained on this, by stating that the power lost in creation of waves can be visualized with the above image.  The power lost, in simple terms, is equivalent to the total amount of water or volume of water displaced by the ship as it sails through, which can be seen as a wake.  The power lost can be visualized in terms of number of wave ripples, height of wake created and the distance it travels due to ship’s speed.  Though his main topic of presentation was on Hull & Propeller condition based and performance based maintenance, we particularly liked the way he presented the wave making resistance.

Watch out this space for more updates from other speakers where they revealed fantastic insights at the IMarEST condition Based Maintenance conference.
