Riser ring assembly

Abstract

Embodiments herein disclose a riser ring assembly. The riser ring assembly includes a riser ring shim attached to an inner part of a frame, and a gasket placed in a channel formed in the riser ring shim. The gasket maintains a watertight seal between the riser ring shim and the frame. The riser ring shim includes a plurality of paddle lock notches, a plurality of through holes, a plurality of counter sunk holes and a plurality of alignment marks, where dimension of the plurality of through holes is different from dimension of the plurality of counter sunk holes. Further, the riser ring assembly includes a top riser ring attached to an upper part of the frame, and a cover attached to an inner surface of the top riser ring.

What is claimed is: 
     
         1 . A riser ring assembly, comprising:
 a frame;   a riser ring shim attached to an inner part of the frame;   a gasket placed in a channel formed in the riser ring shim, wherein the gasket maintains a watertight seal between the riser ring shim and the frame;   a top riser ring attached to an upper part of the frame; and   a cover attached to an inner surface of the top riser ring.   
     
     
         2 . The riser ring assembly of  claim 1 , wherein the riser ring shim comprises a plurality of paddle lock notches, a plurality of through holes, a plurality of counter sunk holes and a plurality of alignment marks, wherein dimension of the plurality of through holes is different from dimension of the plurality of counter sunk holes. 
     
     
         3 . The riser ring assembly of  claim 1 , wherein the riser ring shim is attached to the inner part of the frame using connecting assemblies, wherein the connecting assemblies comprise a socket head cap screw (SHCS) and at least one lock washer. 
     
     
         4 . The riser ring assembly of  claim 1 , wherein the riser ring shim is attached to the frame using connecting assemblies that pass through a plurality of through holes. 
     
     
         5 . The riser ring assembly of  claim 1 , wherein at least one connecting assembly of the riser ring shim and at least one connecting assembly of the frame are vertically aligned with each other. 
     
     
         6 . The riser ring assembly of  claim 1 , wherein the top riser ring is attached to the upper part of the frame using connecting assemblies, wherein the connecting assemblies comprise at least one socket head cap screw (SHCS) and at least one lock washer. 
     
     
         7 . The riser ring assembly of  claim 1 , wherein the top riser ring is attached to the frame using connecting assemblies that pass through a plurality of through holes. 
     
     
         8 . The riser ring assembly of  claim 1 , wherein a plurality of cells is formed over the cover. 
     
     
         9 . The riser ring assembly of  claim 1 , wherein the frame comprises a plurality of supporting units. 
     
     
         10 . The riser ring assembly of  claim 1 , wherein the riser ring assembly is made of a composite material, wherein the composite material is a resin transfer molded (RTM) composite material. 
     
     
         11 . The riser ring assembly of  claim 10 , wherein the RTM composite material is highly resistant to corrosion caused by exposure to a corrosive element. 
     
     
         12 . The riser ring assembly of  claim 10 , wherein the RTM composite material has at least one of: a non-conductive property and a recyclable property. 
     
     
         13 . The riser ring assembly of  claim 1 , wherein the riser ring assembly is made of a composite material, so as to reduce a weight of the riser ring assembly.
