         8 . The diverter assembly of  claim 1 , wherein the plurality of inflatable inner seals is adapted to be serviced by the removal of the canister assembly from the diverter body. 
     
     
         9 . The diverter assembly of  claim 1 , wherein the plurality of inflatable inner seals is adapted to be replaced by the removal of the packer sleeve assembly from the diverter body. 
     
     
         10 . The diverter assembly of  claim 1 , wherein the canister assembly is removable from the diverter body by axial rotation of the canister assembly. 
     
     
         11 . The diverter assembly of  claim 1 , wherein the canister assembly is removable from the diverter body along an axis of the canister assembly. 
     
     
         12 . The diverter assembly of  claim 1 ,
 wherein the canister assembly is configured to be axially coupled to or removed from the diverter body by a breach lock assembly,   wherein the canister assembly comprises one or more breach lock tabs and one or more breach lock slots.   
     
     
         13 . The diverter assembly of  claim 1 , wherein the canister assembly is selectable based on a pipe size to be enclosed within the canister assembly. 
     
     
         14 . The diverter assembly of  claim 1 , wherein the canister assembly comprises an upper plate, a middle plate, and a lower plate, wherein one of the plurality of inflatable inner seals is positioned between the upper plate and middle plate and one of the plurality of inflatable inner seals is positioned between the middle plate and the lower plate. 
     
     
         15 . A diverter assembly, comprising:
 a diverter body, wherein the diverter body is fluidly coupled to an annulus of a wellbore; and   a canister assembly mechanically coupled to the diverter body, wherein the canister assembly is removable from the diverter body,   wherein the canister assembly comprises at least one inflatable inner seal positioned on an inner surface of the canister assembly,   wherein the diverter body comprises at least one inflatable outer seal, wherein the at least one inflatable outer seal is positioned on an inner surface of the diverter body.   
     
     
         16 . The diverter assembly of  claim 15 , wherein the at least one inflatable inner seal is arranged to form a fluid seal between the canister assembly and a drill string or casing. 
     
     
         17 . The diverter assembly of  claim 15 , wherein the at least one inflatable outer seal is arranged to form a fluid seal between the canister assembly and the diverter body. 
     
     
         18 . The diverter assembly of  claim 15 , wherein the at least one inflatable inner seal comprises a plurality of inflatable inner seals.
