  • Riser fill-up valve
    Patent number: 5826658
    Abstract: A fill-up valve is provided for a riser having a longitudinal axis that is connected at one end to a subsea wellhead and at the other end to a platform of an offshore oil or gas well. The fill-up valve is formed from a gate valve that mounts to an exterior of the riser and occupies a position extending less than the entire transverse periphery of the riser. The gate valve has a transverse profile projecting outward from the exterior of the riser that allows passage of the riser and fill-up valve through confined areas, such as through a rotary table of the well. A flow passage of the gate valve communicates with the interior of the riser to allow water to flow into the interior of the riser.
