OFFSHORE ENERGY DEVELOPMENT CORPORATION EUGENE ISLAND BLOCK 163

PIPELINE ABANDONMENT PROCEDURE FOR IMPLEMENTING OPERATION

GENERAL

Offshore Energy Development Corporation (OEDC) is planning the abandonment of a 6-inch pipeline in Eugene Island Block 163. The pipeline commences at the OEDC platform and transverses a route of 23,324 feet (4.42 miles) to a side tap tie-in assembly on an 30-inch ANR pipeline. Drawing No. 54-6-PM-957 presented at the end of this document illustrates the pipeline route and tie-in.

This document, as prepared by MPC International, Inc. (MFC), presents the overall procedure for locating and abandoning the 6-inch pipeline.

EQUIPMENT

The equipment required to perform the abandonment operation as described herein is listed as follows:

• Supply boat • Lift boat with 25 ton crane • Jet pump with hoses • Diving spread (1 supervisor and 3 diving teams) • 3 riggers and 1 rigger/welder • Survey (2 operators with gradiometer sc positioning) • 4 disc bi-directional pig

• Containment barge with tug

PROCEDURE

The operations is divided into activities as described below.

LOCATE SIDE TAP

A supply vessel is mobilized with survey equipment for locating the pipelines and side tap. A positioning system and gradiometer (or magnetometer) will be installed on the vessel. The vessel will mobilize out of Fresh Water City, Cocodrie or Fourchon and travel to Eugene Island Block 163.

August 17, 1995 Pagel

Once on location the vessel will make perpendicular runs to the 30-inch ANR pipeline at a minimum of 500 feet either side of the assumed side tap location. Several runs perpendicular to the lines will be performed moving 100 foot closer to the side tap each time. Buoys or markers will be utilized to mark the alignment. Perpendicular runs will also be made to the OEDC 6-inch pipeline to establish the alignment and mark the route with buoys.

The survey vessel will move to the platform and confirm distance and bearing to the side top with the ANR pipeline.

Once a determination is made as to the location of the side tap, the lift boat will be notified to proceed to location.

UNCOVER SIDE TAP ASSEMBLY

The lift boat with crane, jet pump and diving crew is mobilized from Fresh Water City, Cocodrie or Fourchon to the site. The lift boat is positioned on the east side of the side tap assembly. The vessel is set up and the jet pump used to commence the uncovering operation.

INSPECT THE SIDE TAP ASSEMBLY

Divers will perform a survey ofthe side tap assembly and note the in-situ condition of the assembly. The position of all valves will be confirmed. The location of the 6-inch flange connection will be established and the vessel relocated to that position if necessary. The lift boast will remain on the east side of the side tap assembly.

DISPLACE PIPELINE CONTENTS

Insure valve nos. 1 and 2 on the side tap assembly and valve nos. 4, 5, and 6 on the platform are closed. Lock open check valve, no. 3. Open the 2-inch valve no. 2 on the tie-in assembly and bleed off residual pressure through a bleed hose connected to the surface and routed through a holding tank. Release the flapper on check valve no. 3 and break the flange connection between valves nos. 3 and 1. Install a 6-inch blind flange (ANSI 600#) with a 2-inch ball valve on the side tap assembly and on the end of the 6-inch pipeline. Install a flange connection with a fitting for connecting the discharge hose to the flange on the 2-inch valve installed on the blind flange at the end of the 6-inch pipeline. The other end of the line is rigged to discharge into the containment barge moored near the llft boat The 2-Inch ball valve on the 6-inch blind is opened and the 6-inch check valve no. 3 locked open.

August 17, 1995 Page 2

The ESD valve no. 4 at EI 163 platform Is removed and a temporary pig launcher installed. A 4-disc bi-directional pig is inserted and a hose attached from the volume pump to the pig launcher. The pig is run to the side tap assembly using fresh seawater and discharging the contents of the pipeline into the containment barge.

DISCONNECT AND CAP THE 6-INCH PIPELINE

Break the flange at the subsea tie-in assembly on the platform side of the 6-inch check valve, and recover the spool piece with the 6-inch check valve to the lift boat A blind flange will be installed on the end of the pipeline. A sufficient length of line will be uncovered to move the pipeline a minimum of 20 feet from the side tap assembly. The end will be jetted to a cover of 5 feet

COVER THE SIDE TAP ASSEMBLY

The side tap assembly will be covered with sand/cement bags to a minimum depth of 3 feet of cover.

RISER DISCONNECT

The lift boat moves and sets up at the platform end of the pipeline. The pipeline is cut at the base of the riser at the Eugene Island Block 163 platform. Divers jet the line free of cover for a distance of 50 feet from the base of the platform and cut the line with a underwater hydraulic saw in two places approximately 10 feet apart. The 10 foot pipeline segment is recovered to the deck of the vessel. Plumbers plugs will be inserted into both the riser end and the pipeline end. The ends are buried to 5 feet of cover. The vessel is demobed to Fresh Water City, Cocodrie or Fourchon.

1. The maxinun water depth [(-) 61' MSL] along the proposed pipeline route and in relationship to the natural bottom i s set forth on the attached Flowline Archeological and Hazard Survey.

2. The description of the pipe and coating is as follows:

a. Line Pipe: 6.625" 0.0. x .280" W.T. API SL Grade B or ASTM A106 Grade B seamless; bare weight • 13.98#/ft. Specific gravity in sea water (empty) without coating • 1.239. Pipe will be coated with Scotchkote 206N fusion bonded epoxy 14 nils. Pipe joints will be protected with heat shrinkable wrap-around pipe sleeves.

b. Riser Pipe: 6.625" O.D. x .432" W.T. API SL Grade B or ASTM A106 Grade 8 seamless; bare weight -28.57#/ft. Welded joints will be protected with heat shrinkable wrap-around pipe sleeves. Splash zone will be coated with 1/2" of Splashtron rubberized coating. Below water will be protected by fusion bonded epoxy and above water by sine primer, tie-coat and polyurethane topcoat paint system.

3. Tha proposed pipeline is approximately 23,572.96' in Horizontal length* This does not include the approximate 150' ef vertical riser piping on the platform. The line will transport natural gas and condensate. The facility inlet design working pressure i s 1440, but the existing pressure is limited to 1300 psig by the pipeline.

4. Pipeline valves and flanges will be ANSI Class 600 with a rated working pressure of 1440 psig.

5. The design of the proposed pipeline is in accordance with Department of Interior 30 CFR Part 250 and Department of Transportation 49 CFR Part 192.

6. The cathodic protection system for the flowline will use GALVALUM tapered semi-cylindrical bracelet anodes, calculations are as fallows:

ATTACHMEN1 B

L ep/1 = 3.82 X 104 x W/DIR

Lep/i - Anticipated Life of Line (years) i s 20 years

W = Weight of Anode Unit (pounds) i s 33#.

D = Diameter of Pipe (inches) i s 6.625".

R = Rate of Consumption (#/amp/year) i s 7.6#/amp/year (GALVALUM)

I = Separation between Anodes (feet)

I = 3.82 X 10 4 X W/DRLep/!

I = (3.82 X 10 4 X 33)/(6.625x7.6x20)

I = 1252'

Use one (1) GALVALUM 33# (net) anode every 500 feet.

The design pressure for the r i s e r and line pipe:

t = PD/2S FET (ANSI B31.8)

t = nominal wall thickness, inches

Attention: Mr. Alex Alvarado

RE: Supplemental Information Application f o r Pipeline Right-of-Way OCS-G 10730, Eugene Island Block 163 Offshore, Louisiana

Gentlemen:

In reply t o the recent telephone conversation between yourself and our Mr. Randy Chapman concerning the magnetic anomalies along our proposed pipeline route from Eugene Island Block 163 to Eugene Island 146, we are enclosing four (4) sets of revised survey reports which contain the revised pipeline route drawings which you requested. The revised drawings r e f l e c t relocation of the proposed pipeline route t o the center survey shotline per your recommendation.

This relocation assures that the pipeline w i l l be located on a route where a l l magnetic anomalies have been located by magnetometer. As you require, the three magnetic anomalies of concern on the pipeline route (190, 125, and 390 gammas) w i l l be investigated. Flash w i l l conduct a bottom search and attempt t o i d e n t i f y the source of the anomalies p r i o r to laying pipe over t h a t location. Should the source of any anomaly present a hazard t o the pipeline, then the object w i l l e i t h e r be removed or avoided. We believe that the enclosed information and t h i s proposed procedure w i l l s a t i s f y your request. However, should you require further information please c a l l me at the letterhead address. Your e a r l i e s t reply t o our pipeline application i s respe c t f u l l y requested.

Sincerely,

FLASH GAS & OIL SOUTHWEST, INC.

The exclusion of this activity from future environmental analysis i s conditioned on the imposition of the following mitigative measure(s). These measures are to ensure environmental protectifon, consistent environmental policy, and safety as required .by the NEPA.

Environmental Protective Measures

The following measure was identified in the plan/application by the lessee/operator submitting the proposal: .', None.

The measure identified by MMS during the plan/application review or in the lease stipulation was:

Our analyses indicate that there is/are man-made and/or geologic feature(s) located within 150 meters (490 feet) of the proposed a c t i v i t i e s . The feature(s) may pose a hazard to the proposed operations. Precautions in accordance with NTL 83-3, Section IV.B, w i l l be taken prior to performing the proposed operations.

Exclusion Determination

The proposed action was evaluated and reviewed against the CER exception c r i t e r i a defined by 516 DM 2.3.A(3). With inclusion of the above mitigation, i t does not represent an exception to the categorical exclusions. Therefore, preparation of an EA i s not required.
