Abstract
A subsea safety system () for use during a well treatment operation. The subsea safety system () includes a tubular string having an inner flow passage (). At least one valve assembly () is positioned within the tubular string. The valve assembly () is operable between open and closed positioned to selectively permit and prevent fluid flow therethrough. A frangible liner () is disposed within the valve assembly (). The frangible liner () has a close fitting but not fluid tight relationship with the valve assembly (). The frangible liner () is operable to protect the valve assembly () from particle flow during the well treatment operation. In addition, the frangible liner () is operable to shatter responsive to closure of the valve assembly (), thereby allowing full operation of the valve assembly ().
