Zusammenfassung:A method of installing a secondary seal comprising taking a riser tensioner out of service 112 such that an inner barrel is not reciprocating along an axis of the riser tensioner while out of service, positioning a secondary sealing assembly around the inner barrel, coupling the secondary sealing assembly to a primary sealing assembly circumferentially surrounding the inner barrel 116, the secondary sealing assembly arranged above the primary sealing assembly and bringing the riser tensioner back into service 120. An end cap of the riser tensioner may be removed 114 and the secondary sealing assembly slid along the inner barrel or the secondary sealing assembly may be split into two portions (156 figure 9).
