ABSTRACT:
A tensioner system is disclosed for applying tension to a riser pipe extending between a floating vessel and the sea bottom. The tensioner comprises a guide means fixed onto the floating vessel for restraining guide members from substantial lateral movement relative to the vessel while permitting relative vertical motion of the guide members, means on the vessel for applying vertical tension to the guide members and suitable means for connecting the guide members to the riser such that the vertical tension applied to the guide members is substantially the same as the vertical tension applied to the riser.
