I am looking for coordinates for the offshore LOOP restricted zone. I want to mark 4 way points on my plotter to make it easier to stay out of there.

The Louisiana Offshore Oil Port (LOOP) is a deepwater facility in the Gulf of Mexico near Port Fourchon, LA. It provides a DEEP WATER offloading and temporary storage services for raw petroleum products by deep water tankers. The anchor points AND the underwater pipelines that connect them together and to the shoreline are in a very restricted marine area. USE Caution whenever in the area.

There are NO specific markers that indicate the entire boundary for the LOUISIANA OFFSHORE OIL PORT, but that does not resolve you of any liability for being in the restricted area. These restrictions apply for the entire area, especially in the light of today’s terrorist activity. The restrictions are vigorously enforced.

The rough center of the Louisiana Offshore Oil Port (LOOP) is located about 27 miles at a bearing of 182° Magnetic from Barataria Pass by Grand Isle, LA. and about 19 miles at a bearing of 139° Magnetic from Belle Pass at the Gulf of Mexico by Port Fourchon.

It occupies about a twelve (12) mile east to west by six (6) mile north to south area that resembles an oval. The LOOP has a series of regulations that are listed in Chapter 2 of the U.S. Coast Pilot publication. Additional restrictions are published in the USCG official NOTICE TO MARINERS that is published weekly. I strongly suggest that you get up to date information, as world events have installed a strict enforcement of the regulations.

The LOOP is in part or all of the following GRAND ISLE LEASED BLOCK AREA’s: Blocks 51, 52, 53, 54, 56, 57, 58, 59, 60, 63, 64, 65, 66 and 67.

The site of the LOOP is shown on NOAA Marine Chart # 11359 ~LOOP DEEPWATER PORT, Chart 11358 ~ Barataria Bay and Approaches, and on Chart # 1116A Leased Blocks Miss River to Galveston.

I strongly suggest that get a current copy of these charts BEFORE navigating to the area.

Some of the LOOP tie up ship markers located around the area are located at the following locations:


G -“1”, a Horn @ 28° 48.608’ N. Latitude ~ 89° 54.991’ W. Longitude
G - “3” @ 28° 50.141’ N. Latitude ~ 90° 02.404’ W. Longitude
R - “2” @ 28° 50.330’ N. Latitude ~ 89° 53.861’ W. Longitude
Y - “L-B” @ 28° 52.060’ N. Latitude ~ 89° 52.701’ W. Longitude
R - “4” @ 28° 54.861’ N. Latitude ~ 89° 57.001’ ~ ~ W. Longitude

Comparing these positions to the charts, you will note that these positions are NOT joined in straight lines between the buoys. These boundary lines and buoys, however, are indicated on the charts.

Again, be sure that you know the restrictions (and penalties) for the LOOP area before venturing close to the site.

Unless otherwise specified, all positions are stated as Degrees, minutes and thousandths of minutes (DDD,MM.mmm) and were determined using WGS 84 Datum. All bearings and courses are stated in Magnetic degrees.

I can attest first hand that they enforce the zone. Many years ago I wondered in there. I had a crew boat painted all black intercept us and excort us out. They took picks of my boat and said they were not going to board us because we had several kids with us. They were polite but FIRM. There was rumor that they were NAVY SEALS. I don't really know about that didn't have any ID on the boat it looked like a regular crew boat but was flat black and the windokws were dark. Now that I am back fishing the GI area I want to give them plenty of room.
Thank you Captian Paul I will get the charts you rdecommended
