A blowout recovery vehicle for recovering the discharge from underwater wells comprises a large inverted entrapment shell positionable over a well and having overly extending tubes connected by hose means to surface separation and storage equipment. Floatation tanks are connected to the surface by air lines which are actuated to adjust the buoyancy of the device to raise or lower it so that it can be lowered over a well to trap the discharge from the well. In use, the assembled device can be towed by a tug into position or can be assembled in the water at the site and lowered over the well without the necessity of the tug coming into the effluent discharge area above the well. Alternatively, an anchor can be placed in the seabed directly upstream of the well at some distance from the well. The device can be tied to the anchor by a tow line of exact length equal to the distance between the well and the anchor and positioned either to the right or left of the well so that the force of the current will cause the device to swing about the anchor so that guidance from a surface vessel can position the device over the well.
