Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A riser tension augmentation system comprising:
 a riser joint collar; and   a plurality of inflatable sleeves attached to the riser joint collar,   wherein each inflatable sleeve comprises a fill valve, a relief valve, and a bleed valve.   
     
     
         2 . The system of  claim 1 , further comprising:
 a strap configured to secure the plurality of inflatable sleeves.   
     
     
         3 . The system of  claim 1 , wherein the riser joint collar comprises a shaft collar. 
     
     
         4 . The system of  claim 1 , wherein the riser joint collar comprises a shaft collar clamp. 
     
     
         5 . The system of  claim 1 , wherein the riser joint collar comprises a c-clamp. 
     
     
         6 . The system of  claim 2 , wherein each of the plurality of inflatable sleeves comprises a strap loop. 
     
     
         7 . The system of  claim 1 , wherein each of the plurality of inflatable sleeves is attached to the riser joint collar by one or more shackles and one or more slings. 
     
     
         8 . The system of  claim 1 , wherein each of the plurality of inflatable sleeves comprise an inflatable air bladder. 
     
     
         9 . The system of  claim 8 , wherein the inflatable air bladder is disposed within a protective cover. 
     
     
         10 . A method of augmenting riser tension comprising:
 attaching a riser joint collar to a riser joint; and   attaching a plurality of inflatable sleeves to the riser joint collar.   
     
     
         11 . The method of  claim 10 , further comprising:
 deploying the plurality of inflatable sleeves attached to the riser joint collar.   
     
     
         12 . The method of  claim 10 , further comprising:
 securing the plurality of inflatable sleeves by a strap.   
     
     
         13 . The method of  claim 11 , further comprising:
 inflating one or more of the plurality of inflatable sleeves.   
     
     
         14 . The method of  claim 13 , further comprising:
 deflating the plurality of inflatable sleeves.   
     
     
         15 . The method of  claim 10 , wherein the riser joint collar comprises a shaft collar. 
     
     
         16 . The method of  claim 10 , wherein the riser joint collar comprises a shaft collar clamp. 
     
     
         17 . The method of  claim 10 , wherein the riser joint collar comprises a c-clamp. 
     
     
         18 . The method of  claim 10 , wherein each of the plurality of inflatable sleeves is attached to the riser joint collar by one or more shackles and one or more slings. 
     
     
         19 . The method of  claim 10 , wherein each of the plurality of inflatable sleeves comprise an inflatable air bladder. 
     
     
         20 . The method of  claim 19 , wherein the inflatable air bladder is disposed within a protective cover.
