Value proposition

The HMH optiWOB smart module minimizes weight on bit (WOB) variations and boosts the performance of the drill string compensating system. In all heave compensator systems, there is friction. This comes from cylinder pistons, wire sheaves, guide rails, etc. This friction force works against the heave motion and results in variations in weight on bit (WOB) when drilling.

WOB variations lead to several disadvantages:

Reduced rate of penetration (ROP) Excessive wear on drill bit High WOB setting or risk bit lift off Fluctuations in rotation torque

HMH optiWOB smart module counters the friction in the passive compensator system by using the Active Heave Compensator (AHC) already installed on most HMH compensators and RamRig™ deliveries.
