Gentlement

Pursuant to the authority granted by i»3 U.S.C. 1334(e) and 30 CFR 250.150(d), your applloation dated July 21, 1988, for a pipeline right-of-way two-hundred feet (200*) in width for the installation, operation, and mlntenanoo of a 6 5/8-lnoh pipeline, 1.57 olles in length, is hereby approved, as proposed.

The proposed pipeline will transport natural gas and condensate from Brooklyn Union Exploration Company, Inc.'s Platfona A in Blook 280, South Marsh Island Area, North Addition, aorosa Blook 269, Smith Marsh Island Area, North Addition, to Placid Oil Company's Platform A in Blook 268, South Marsh Island Area, North Addition.

This approval is subject to the following conditions:

1. There are pipelines located within 500 feet of the proposed aotivities* Precautions as outlined in Notice to Lessees and Operators (NTL) No. 83-3. Section IV.B.l. shall be taken prior to conducting the proposed operations.

2. The unidentified magnetic anomalies listed below may represent archaeological resources. In accordance with (NTL) No. 75-3 (Revision No. 1, Enclosure No. 3). you shall either determine that the potential archaeological resources do not have historic significance, or avoid them when conducting proposed activities as indicated by the avoidance criteria below:

NEPA CATEGORICAL EXCLUSION REVIEW

The Categorical Exclusion Review (CER) evaluated the proposed action and determined that it meets the categorical exclusion criteria as defined by 516 DM 2.3A(1) which states "(a) The action or group of actions would have no significant effect on the quality of the human environment, and (b) The action or group of actions would not involve unresolved conflicts concerning alternative uses of available resources." The analysis of potential impacts by environmental and resource specialists was based on the assumption that the following mitigative measure(s) will be imposed.

Environmental Protective Measures

The following measure(s) was/were identified in the plan/application by the lessee/operator submitting the proposal: None.

The measures identified by MMS during the plan/application review or in the lease stipulation were:

1. There are pipelines located within 150 meters (490 feet) of the proposed activities. Precautions in accordance with NTL No. 83-3, Section IV.B, will be taken prior to conducting the proposed operations.

2. The unidentified magnetic anomalies or side-scan sonar contacts listed below may represent archaeological resources. In accordance with NTL No. 75-3 (Revision No. 1, Enclosure No. 3), the applicant will either determine that the potential archaeological resources do not have historic significance, or they will avoid them when conducting proposed activities as indicated by the avoidance criteria below:

RE: Application for a 6.625-Inch O.D. Natural Gas Pipeline to be Installed In and/or through Blocks 280, 269 and 268, South Marsh Island Area, Gulf of Mexico, Federal Waters, Offshore Louisiana

Gentlemen:

Pursuant to the authority granted in Section 5(e) of the Outer Continental Shelf Lands Act (67 Stat. 462 (43 U.S.C. 1331), as amended (92 Sta. 629), and in compliance with the regulations contained in Title 30 CFR, Part 250.150(b), Brooklyn Union Exploration Company, Inc. (Brooklyn Union), hereby submits this application in quadruplicate (original ana three copies) for a right-of-way two hundred feet (200') in width for the construction, maintenance and operation of a 6.b25-inch O.D. natural gas pipeline in the South Marsh Island Area, Gulf of Mexico. Brooklyn Union agrees that said right-of-way, if approved, will be subject to the terms and conditions of said regulations.

This 6.625-inch O.D. pipeline will be used to transport gas and condensate from Brooklyn Union's proposed Platform "A" (Well No. 2) OCS-G 5197 in South Marsh Island Area Block 280 to Placid Oil Corporation's (Placid) existing Platform "A", OCS-G 2310 in South Marsh Island Block 268. The pipeline will depart Brooklyn Union's proposed Platform "A" in South Marsh Island Block 280 in a northeasterly direction and go approximately 8,285 feet (1.57 miles) to Placid's Platform "A" in South Marsh Island 268, all being in the Gulf of Mexico, Federal Waters, Offshore, Louisiana. The proposed construction commencement date is August 30, 1988, with the time reguired to lay the pipe being estimated at 5 days with an overall completion of project time being estimated at 21 days. The base of operations will be Grand Chenier, Louisiana.

GENERAL INFORMATION & CALCULATIONS

6.625" O.D. GAS & CONDENSATE SALESLINE

SOUTH MARSH ISLAND BLOCK 280 TO SOUTH MARSH ISLAND BLOCK 268

1. The water depth along the proposed pipeline route and in relationship to the natural bottom i s set forth on the attached PLAT. Water depth i s (-) 36' MSL at the proposed Platform South Marsh Island Block 280 and (-) 32' MSL at Placid's "A" Platform, South Marsh Island Block 268.

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

a. Line Pipe: 6.625" O.D. x .280" W.T., API 5L Grade B seamless; bare weight = 18.98# per foot. Coated with 12-14 mils of Scotchkote 205 fusion bonded epoxy. Specific-gravity in seawater (empty) = 1.25. Welded joints w i l l be protected with heat shrinkable sleeves.

b. Riser Pipe: 6.625" O.D. x .432" W.T. API 5L Grade B seamless. Bare weight = 28.58# per foot. Coated with 12-14 mils Scotchkote 205 fusion bonded epoxy and 1/4 splash-tron at +/" 2 0 MSL.

c. Internal Coating. The analysis of transported products w i l l be monitored.

3. The proposed salesline i s approximately 8,285 feet long. This does not include the +/- 94' of r i s e r piping at the platform. The line w i l l transport natural gas and condensate.

4. Valves and flanges on the proposed platform w i l l be 600# ANSI.

5. The design of the proposed saleslines and r i s e r s i s in accordance with the DOT T i t l e 49, Part 192, API RP 14E and 30 CFR Part 250 Subpart J .

6. The cathodic protection system for the pipeline w i l l use zinc tapered semi-cylindrical bracelet anodes. Calculations are as follows:

a. Anticipated line l i f e i s 20 years.

b. Assumed maximum of 2% bare pipe.

c. Current 5 MA/sq. f t .

d. 26 #/amp year

e. Anode spacing calculations:

Area/mile = 5280~ft:/iniT x 3.14 x i6i625)/12 f t .

= 9153 sq. f t . / m i .

Amps = 9153 sq. f t / mi. x .02 x .005 A/sq.ft.

= .9153 amps/mi.

Line l i f e = .9153 A/mi. x 20 = 18.31 amp yr./mi.

#/mile = 18.31 amp yr/mi. x 26 #/amp y r .

= 476.1 #/mile

Anode spacing = (476.1 #/mi.)/80# = 5.95/mi.f 887 f t .

Use one (1) 80# every 500 fe e t .

7. The design pressure f o r the l i n e pipe and r i s e r :

a. Riser:

t = PD/2S P = i n t e r n a l design

pressure = 1440 psig

= 1440 x 6.625 /(2 x 17,500) t = w a l l thickness, inches

= .273 + 1/16" C.A. S = SMYS X .5 = 17,500

= .335 D = nominal outside

diameter = 6.625"

Use 6.625" O.D. x .432" W.T. API 5L Grade B seamless

Hydrostatic t e s t pressure:

I n accordance with.API 14E

HTP = 1.5 x MAOP

= 1.5 X 1440 = 2160 PSIG

b. Line Pipe:

t = PD/2S P = i n t e r n a l design

pressure = 1440 psig

= 1440 x 6.625 /(2 x 25,200) t = wa l l thickness, inches

= .189 + 1/16" C.A. S = SMYS X .72 = 25,200

= .252 D = nominal outside diameter = 6.625"

Use 6.625" O.D. x .280" W.T. API 5L Grade B seamless Hydrostatic t e s t pressures

In accordance w i t h DOT T i t l e 49, Part 192

HTP = 1.25 x MAOP + external pressure

= 1.25 X 1440 + 35 f t . X (1.02)/2.31 p s i / f t .

= 1815 PSIG (use 2160 PSIG - same as r i s e r )

8. The hydrostatic t e s t w i l l be conducted i n accordance w i t h applicable regulations. Test duration w i l l be eight hours. The t e s t pressure i s less than 90% of the hoop stress using the steel's SMYS.

9. The s p e c i f i c g r a v i t y of the l i n e pipe was calculated as follows:

The l i n e pipe weighs 18.98 Ibs/LF

The pipe displaces D /4 x 12/1728 x 62.4 x 1.02 = 15.23 lbs w a t e r / f t

Specific g r a v i t y f l o w l i n e = 18.98/15.23 =1.25

The weight of coatings, anodes, and other materials was not considered i n these c a l c u l a t i o n s .

10. The design capacity of the f l o w l i n e i s approximately 30 MMSCFD gas and 900 BCPD.

Specific g r a v i t y of condensate = 50 API and .65 f o r gas.

11. The proposed flowine w i l l t i e - i n at the 22" Trunkline Pipeline South Marsh Island Block 268. (Placid "A" Platform)

12. Overpressuring of the salesline shall be prevented by the following method. The pipeline shall have both high and low limits. High limits-shall beset no higher than 10% above operating pressure and in no case above the maximum rated pipeline pressure. The low pressure shut-in shall activate no lower than 10% below the operating pressure. The effect of any pressure exceeding either limit wi l l be the automatic and orderly shutdown of a l l pressure sources on the platform.
