Vacon is the market leader in Norway in supplying drive systems for electric active heave-compensated (AHC) winches. AHC winch systems are increasingly being deployed for lowering and lifting equipment to and from the seabed at depths down to 3,000 meters. By compensating for any undulations or heavy sea movements that cause sudden slack or pull on cables, they especially meet the need when extracting oil from wells deep under the sea in extreme, harsh conditions, including high seas.
