Soft starters for the Oil & Gas Industry

Submersible crawler for subsea drilling
Motor ratings: 6600V, 60A

Drilling for oil is a rugged undertaking at the best of times; it is safe to say then, that drilling for oil on the ocean floor is a most unforgiving undertaking.

When the Theis company of Germany undertook to build a subsea drilling submersible crawler powered by an hydraulic power pack, they new to call on Solcon for a solution to the problems inherent in starting motors due to high inrush current.

The relatively small scale electrical distribution system typical on board any ship combined with the long power lines energizing the subsea crawler in this application would create unforgiving voltage drops if Solcon soft starters were not installed to smoothly transform power the hydraulic pump.
