R J Brown Initiates

Pipeline Study For

Alaskan Diapir Area

R J Brown and Associates,

Houston, has initiated a joint in- dustry study on the feasibility and costs of offshore pipeline transpor- tation in the Diapir area, off

Alaska. This area is subject of planned OCS Lease Sale 87, scheduled for mid-1984.

A significant portion of this area is permanently covered by the Po- lar ice pack. Novel pipeline con- struction techniques need to be in- vestigated and developed in order that submarine pipelines can be economically installed in such an environment.

Subjects to be addressed include establishing a data base, design criteria, review and selection of pipeline installation and trench- ing methods, and cost estimates.

Companies interested in joining the study as a late participant should contact Jim Gillespie at the RJBA Houston office, tele- phone (713) 683-9333, telex 762186 or 4620114.
