Active heave compensation (AHC) is a technology used in maritime and offshore engineering to counteract the vertical motion of a vessel caused by waves and sea conditions. Its primary purpose is to maintain the position of equipment, such as cranes or submersible vehicles, while they are being deployed or operated from a moving platform like a ship or offshore platform.
