INTRODUCTION Date Created: 10.08.12

This document presents the design justification for a composite repair application.

42 X52 Petroleum Jetty Relief Vessel w/153mm (6 ) axial defect X 3352 mm (132 ) circumferential defect w/32% wall loss and a design pressure of 28 bar (400 psi) caused by "External Corrosion"

NRI recommends that the repair area of the pipe be sandblasted or an MBX handtool be used to create a Sa 2.5 or NACE 2 SSPC (near white metal) with a .5mm 1mm anchor pattern followed by a SSPC-SP- . The surface preparation will need to extend 177mm ( 7 ) on either side of the defect area as specified within the calculations provided. Once the surface preparation has been completed, NRI proposes the Syntho-Poxy HC a high compressive strength two-part A & B epoxy be used to fill the external corrosion pits and to profile the weld seam to match the contour of the outside diameter of the pipe. Once all anomalies have been filled with the Syntho-Poxy HC NRI recommends the Syntho-

30-60mils (0.76cm-1.5cm) around the entire circumference of pipe make sure to extend the coverage 2" (beyond both ends of the minimum composite repair length as . The epoxy should cover 100% of the defect region and extend over the existing mainline coating at both ends of the composite sleeve to ensure 100% of the repair area is protected from external corrosion. The composite sleeve will provide a load transfer median engineered to cycle and work with the pipeline.

The following composite calculations have been completed to conform to the ASME-PCC2 & ISO TS 24817 standards for nonmetallic repairs of high risk applications for piping and pipe works.

NRI's composite calculations recommend 4 layers of a 100,000 tensile/hoop strength carbon fiber composite sleeve be applied over 508mm (26") centering the defect area which is estimated to be [163 mm (6 ) in the axial length X 3362mm (132 ) in circumferential length] in the middle of the composite sleeve. The composite calculations are based on a design pressure of 28 bar (400 psi) for the API 5L X52 pipe with an original wall thickness of 9.5mm (.375 ) that has been inspected to have a minimum remaining wall thickness of 6.5 mm (.255 ). The source of the wall loss has been identified as external corrosion allowing the composite calculations to engineering the repair thickness of the composite sleeve to take into account the remaining Rstrain of the host pipe which has been identified to be 6.5mm (.255 ). The composite calculations confirm that a 4 layer 2.8mm (0.112") thick composite sleeve be installed around the total repair area to rehabilitate the structural integrity of the defect area on the API 5L X52 petroleum jetty relief vessel. The composite sleeve is engineered to arrest the external corrosion, while also providing the structural strength to meet the design pressure of 28 bar (400 psi) for a minimum of 20 years if the UV protective coating is maintained thru the life of the repair.

Procedures to be taken in handling and storage: For ideal shelf life, store in a cool, shaded area at an ambient temperature of 72°F (23°C). Do not expose materials to

temperatures above 110°F (44°C) or below 40°F (5°C).

Viper-SkinTM is packaged within a hermetically sealed foil pouch to protect the Viper-Skin outer composite wrap from

atmospheric moisture. Because the Viper-Skin composite wrap cures when exposed to the application of water or air

humidity, care must be taken in handling the sealed bags to prevent puncturing or scuffing. If the protective foil pouch is

punctured the Viper-Skin composite wrap will be exposed to atmospheric moisture which will cause the Viper-Skin

composite wrap to cure within the foil bag.

NOTE: Do not open the bag containing Viper-Skin until you are ready to use it.

Shelf Life: NRI provides a 12 month shelf-life if Viper-Skin is stored in a cool dry place and the protective foil pouch is

free from puncture damage.

layer of Syntho-GlassXT and recommend number of layers of Viper-Skin composite.

7.1.4. Unroll the tape, keeping it as close to the surface of the pipe as possible. Do not use a long lead of tape. The roll of tape shall always be in an upright position, with the tape being applied from the lower edge of the roll to maintain proper pressure.

7.1.5. Apply sufficient tension by pulling on the roll of tape as the layers are being applied.

7.1.6. The Syntho-GlassXT tape shall be spirally wrapped around the pipe from right to left or from left to right. NOTE: Only 1 layer of Syntho-GlassXT applied at a 20% overlap is required before applying the recommended number of layers of Viper-Skin.

NOTE: The Viper-Skin composite must start 1" (2.54cm) inside of the same starting point of the

1primary layer of Syntho-GlassXT. The Viper-Skin composite MUST be applied in the same clockwise

direction or counter clockwise direction as the 1 primary layer of Syntho-GlassXT.

NOTE: 1 layer of Syntho-Glass XT MUST be applied at a 20% overlap as the primary (first) layer

directly over the SubSeaLV epoxy before applying the recommend number of layers of Viper-Skin.

7.2. Application of Viper-SkinTM on Straight Piping

NOTE: Do not open the bag containing Viper-Skin until you are ready to use it, as the atmospheric moisture

which will cause it to cure.

INSTALLATION GUIDE

In cold weather applications, the temperature of the repair area must be brought up to 40F (5C) prior to the

application of Viper-Skin since its resin component will not begin to cure at lower temperatures.

7.2.1. Water shall be sprayed on each layer of Viper-Skin as it is being applied, rather than immersing the roll in water before application.

7.2.2. Each completed Viper-Skin application shall have the specified number of layers, and be the specified

7.2.8. The completed Viper-Skin application shall be overwrapped by four layers of compression film &

perforated using the perforator tool. The compression film may be removed when Viper-Skin has reached its initial cure time.

7.3. The Viper-Skin installation shall be ready for service when the resin has cured sufficiently to provide adhesion between layers and has reached a hardness of 80 Shore D.

7.4. For vertical installations such as Offshore Risers or Jacket Legs, Viper-Skin application shall begin at the bottom of the repair area and proceed upwards.

7.5. For sub-sea and splash zone installations, the last (outer) wrap shall be tied down or overwrapped in a manner that will ensure that the currents or wave action will not affect the adhesion of the last layer of fiberglass tape before the resin has reached its initial cure.

7.6. For sub-sea installations, open the bag of Viper-Skin underwater, at the repair site, after all cleaning is completed and all epoxies have been applied.

INSTALLATION GUIDE

7.7. For higher impact resistance, apply additional layers of Syntho-Glass®24 over the Viper-Skin.

NOTE: For Non-Buried applications, a Viper-Skin installation must be coated with a UV-blocking and

weather resistance coating of Syntho-GlassUV, or an approved coating by NRI.

7.8. For cold weather installations, follow procedures above. However, as an additional step, after applying the final outer wrap of a compression film, then apply a heating pad over the entire repaired area since Viper-Skin

will not cure by itself at temperatures under 40ºF (5oC). )

7.9. For hot weather installations, follow procedures above. However, use ice water in the sprayer if possible, to slow down the curing and thus allow the installer sufficient working time. Furthermore, store unopened bags of Viper-Skin in a separate container in an ice chest if possible.
