For use with a subsea well incorporating an external conductor pipe extending upwardly above the seabed, a protector apparatus is set forth. In the preferred and illustrated embodiment, the preferred embodiment describes a longitudinally split, flange equipped, bolt joined longate conductor clamp supported on a frame at the bottom thereof and having a plurality of appended upstanding braces. The bottom frame is adapted to be rested on a seabed and held in place by a number of anchors driven into the seabed at corners. This apparatus is selectively installed after completion of a well wherein the conductor pipe extends above the bottom, and the apparatus is subsequently removed after protecting the pipe after drilling but before installation of a platform.
