The SCV 3000 work class ROV system is a development of the successful SCV 3000 100 ROV used since 1997. The ROV is a powerful high thrust vehicle pro-pelled by Curvetech thrusters producing 720 kgs of vectored thrust driven by a 100 SHP electro-hydraulic power pack. The SCV 3000 is a powerful, versatile and cost effective 4th generation ROV work system.
