(x) TYPE OF PROTECTION TO THE AFFORDED CROSSING PIPELINES, SUBSEA VALVES, TAPS AND MANIFOLD ASSEMBLIES
Pipeline Burial
The proposed pipeline will be buried to a minimum depth of three feet below natural bottom.
Pipeline Crossings
The proposed pipeline does not cross any existing pipelines.
Subsea Valves, Taps, and Manifold Assemblies
The proposed subsea components (valves, taps or assemblies) will be covered to a minimum of three feet using sand bags.
Riser Protection
There is no pipeline riser.
(xi) ADDITIONAL DESIGN PRECAUTIONS
Additional design precautions will not be required to enable the pipeline to withstand the effects of water currents, storm or ice scouring, soft bottoms, mudslides, earthquakes, perfafrost or other environmental factors.

Arena Offshore, LP Eugene Island Block 213 Subsea Hot Tap Installation Procedure on 14-Inch ROW OCS-G 29378/Segment No. 19785
Hot Tap Size: 14" x 6" Fitting Manufacturer: Oceaneering Construction Code: API 1104 Pipe Type: Carbon Streel Water Depth: 110' Flange Configuration: RTJ ANSI Rating: 900 Pipe Diameter: 14-Inch Pipe Wall Thickness: 0.350" MAOP: 1000 psi
Max. Allowable Operating Temperature: 100oF
Notes:
• Hot Tap Contractor to provide a copy of machinery pressure test certification report.
• Pre-fabricated UWTI assembly has been hydrostatically tested onshore to 1.25 x MAOP for a minimum duration of 4 hours.
• The existing 14-Inch pipeline (Segment No. 19785] is flowing Oil from Eugene Island Block 341 to Ship Shoal Block 28, Current Operating Pressures are less than 400 psig
Procedure: 1. Company will mobilize a Dive Boat with a Saturation Dive Spread. 2. Upon arrival Dive Boat will set anchors. All anchors will be a minimum of 500' from
foreign pipelines and the Arena and Renaissance pipelines, the anchor lines will not cross any pipeline except the 6" Renaissance pipeline being connected and the 14" Arena Pipeline being Hot Tapped for the connection. Once in position the anchors will be 1000' in the direction of pull from the anchors to the pipelines.
3. Divers will remove concrete and somastic with water blaster and hydraulic chipper. 4. Utilizing hydraulic grinders with Z pads, divers will clean the 14" pipe to bare metal
at the 14"x6" Hot Tap Clamp Location. 5. Divers will confirm the longitudinal weld seem is located outside of the hot tap
cutter area, using an Ultrasonic probe. 6. Divers will take UT readings at the 14"x6" Hot tap location as per Installation
Contractors and Hot Tap Technicians instructions at every clock position to verify wall thickness.
7. Utilizing an ovality gauge, divers will verify proper roundness of the 14" pipe at the hot tap location as per Installation Contractor and Technicians Instructions.
8. Divers will take CP reading on the 14" pipeline at the Hot Tap Location. 9. Assemble and check hydraulics on the deck. 10. Testing and recording hot tap travel: Attach crank handle to the hot tap machine
and turning clockwise, count and record the number of turns it takes to advance the pilot to where it will make contact with the outer edge of the pipe.

11. Crank the handle clockwise and advance the cutter until it has gone the required distance to complete the cutout. Count and record these turns. Using the crank handle, turning counter-clockwise, retract the boring bar to where the pilot is withdrawn past the edge of the pipe and is within two [2] turns from the original location of the outer edge of the pipe.
12. Take the crank handle and tie off to the hot tap machine. 13. The pre-assembled hot tap clamp, 6" ball valve, and tapping machine will be
launched overboard and lowered to the 14" Pipeline for installation as per Installation Contractor and Hot Tap Technicians Procedures
14. All bolts on the 14"x6" Hot Tap Clamp shall be tensioned as per the Installation Contractor and Hot Tap Technicians Procedures.
15. The Hot Tap Assembly will be pressure tested as per the Installation Contractor and Hot Tap Technicians Procedures to ensure a proper seal and verify no leaks.
16. Upon a successful test, divers will coat any remaining bare pipe with SeaShield 525 Epoxy and support the Hot Tap clamp with 3:1 sand/cement bags.
17. When the hot tap assembly has been placed on the pipeline and the hoses and fitting have been pressure tested (test pressure = 1000 psi], send down hydraulic hoses and attach to the hot tap assembly.
18. With crank handle attached, advance the boring bar to where the pilot hits the outer edge of the pipe.
19. Turn crank handle counter-clockwise one (1] full turn and then push the engagement handle. Verify engagement and remove crank handle. Start tap and check cutter travel every 15 minutes.
20. Shut off hydraulics and using crank handle, disengage machine;, then turning clockwise, advance boring bar two (2] turns, ensuring cut is complete. Turn crank handle counter-clockwise to retract the boring bar. Close the valve on the hot tap assembly. Vent pressure and remove machine
21. Lower UWTV assembly to depth and install gaskets and bolts to make up flange. 22. Torque bolts with hydraulic torque wrench to values specified by Contractor. 23. Install 3:1 sand/cement bags to support UWTV assembly. 24. Check hydrostatic test hose to 1250 psi and equipment for leaks. 25. Deploy Vz" hose and connect to Vz" connection on blind flange on UWTV. 26. Perform 1 hour leak test for UWTV assembly to Hot Tap Valve, pressure to 1250 psi 27. Disconnect test hose and cover UWTV and Hot Tap assembly with sand only bags.
