PERMIT SOUGHT FOR COMBINED MOBILE LINE

Six U.S. interstate gas pipelines have asked the Federal Energy Regulatory Commission to approve their plan to transport as much as 1.2 bcfd from Mobile Bay off Alabama. The companies want to combine competing pipeline projects into a single $230 million onshore and offshore system (OGJ, Oct. 8, 1990, p. 42).

Six U.S. interstate gas pipelines have asked the Federal Energy Regulatory Commission to approve their plan to transport as much as 1.2 bcfd from Mobile Bay off Alabama.

The companies want to combine competing pipeline projects into a single $230 million onshore and offshore system (OGJ, Oct. 8, 1990, p. 42).

ANR Pipeline Co., Southern Natural Gas Co., Tennessee Gas Pipeline Co., Texas Eastern Transmission Corp., and Transcontinental Gas Pipe Line Corp. will jointly own the onshore segment of the project. Florida Gas Transmission Co. will lease capacity.

Onshore facilities will include Transco's existing 30 in. line that extends 123 miles from Mobil Exploration & Producing U.S. Inc.'s gas processing plant in Mobile County, Ala., to connect near Butler, Ala., with its mainline.

The system will connect near Citronelle, Ala., with Florida Gas's mainline, where ANR, Southern, and Tennessee will lease capacity to move gas on Florida Gas to their mainline systems.

Texas Eastern will lease capacity from Transco to move natural gas from the interconnect at Butler to its mainline.

As primary project constructor on the $150 million onshore project, Southern Natural will lay a pipeline loop and add compression to increase capacity to 1.2 bcfd from 300 MMcfd.

It also will lay lines connecting existing onshore facilities with new facilities offshore.

Onshore capacity will be allocated to ANR 150 MMcfd, Florida Gas 185 MMcfd, Southern Natural 175 MMcfd, Tennessee 175 MMcfd, Texas Eastern 150 MMcfd, and Transco 365 MMcfd.

PLANS OFFSHORE

Florida Gas, Southern Natural, Tennessee, Texas Eastern, and Transco will jointly construct and own the proposed 77 mile, 600 MMcfd offshore pipeline in Mobile Bay, extending from Main Pass Block 252 to Shell Offshore Inc.'s gas treating plant being built onshore near Mobil's plant. The offshore system will consist of a 30 in. line extending 27 miles from shore to a junction platform on Mobile Bay Block 955 and a 26 in. line running 50 miles from Mobile Bay Block 955 to Main Pass Block 252.

Transco will build the $80 million offshore system and Florida Gas will operate it.

Offshore capacity will be allocated as follows: Florida Gas 96 MMcfd, Southern Natural 100 MMcfd, Tennessee 87 MMcfd, Texas Eastern 61 MMcfd, and Transco 243 MMcfd.

Construction is to begin in mid-1991.
