1) The RWIS is designed for a minimum of 20 years shelf life. Cathodic protection is designed for a minimum of 1 year installed subsea.2) The pumping design life sets the parameters for allowable erosion rates during the pumping life of the RWIS.3) The exposure time is the minimum design life of any elastomeric seals exposed to kill mud.
