Old Oil structures in Tiger Shoal?

Reply
 
I am told that there were several Oil Platforms, Old well Heads &/or other Oilfield Sites within the Tiger Shoal area that have been removed in years past. I am interested to know if you have the coordinates for some of these sites and their removal dates(or estimated dates)? My reason is, Im assuming there is still some sort of rock or shell pad left behing which might be good for fishing.
Thank you

Tiger Shoal wells
~ Captain Paul's response to: ~ M-12~

Wow ! M-12, you are asking for a detailed positions of over 200 well sites ~ platforms in the Tiger Shoals area. This Shoal area is about 10 miles south southwest from the Southwest Pass of Vermillion Bay at a bearing of 201 Mag. It is a shoal area that appears on maps as a large banana laying in a east to west position. There are numerous well sites as well as wrecks and underwater mounds through the shoal area.

I do not have the time or the space to adequately provide you with all of the information you need but, I will provide you with some of the major sites and will steer you in a direction that you can obtain all of the information you need for yourself.

The United States coastline is divided into areas that are called LEASED BLOCK AREAS. These areas are usually named for a feature along the coast or an underwater geological feature. These leased areas are then divided into blocks, which is usually rectangular in shape specified by latitude and longitude using North American Datum of 1927 (NAD 27 DATUM). Yes, I know, the current World Geodetic System of 1984 (WGS 84) Datum is more accurate, but the leases were determined years ago using the older NAD 27 datum. I was told by U.S. Department of the Interior, Bureau of Ocean Energy Management, Regulation, and Enforcement (BOEMRE) people that it would nearly be an impossible task to amend all of the hundred thousands of leases with the WGS datum. New leases are now plotted in both NAD 27 and WGS 84 Datum. The government conducts lease sales for the right to explore and produce minerals from these lease blocks.

As there are no sign posts in the offshore waters, specific areas are called by their Leased Area and Block number, such as Vermillion ~ 50, meaning block 50 in the Vermillion Bay area.

First you will need a rough idea where these different sites are located. By that I mean in which of the U.S. Dept of the Interior, BOEMRE, Offshore LEASED BLOCKS your quests are located.
BOEMRE is a renamed bureau of what was the Department of the Interior, formally called the Mineral Management Services (MMS).

The location of the specific BLOCK number in the Leased Area the will put you in the general area were the platforms are located. The government then conducts lease sales for the right to explore and produce minerals from these lease blocks.

U.S. Department of the Interior, Bureau of Ocean Energy Management, Regulation, and Enforcement (BOEMRE) is the authorized agency to lease offshore areas for mineral exploration and production. All platforms are REQUIRED to be listed by MMS. They are the federal repository for the lease data and the exploration and production information in these areas. It is like a general grid system of the areas that will at least get you close to the area of your concern. They keep current and past well sites in a very detailed format.

The genesis of your search should start with the maps or charts that show these LEASED BLOCKS. NOAA Marine Chart 1116A ~ Leased Block for Mississippi River to Galveston TX shows the BOEMRE Leased Areas and the Leased Blocks within those areas. This chart covers the entire Northern Gulf of Mexico waters in the area from the mouth of the Mississippi River to Galveston TX.

For those of you who fish the mouth of the MS River eastward, get NOAA Marine Chart 1115A Leased Block for Cape St George FL, to Mississippi River Passes

After locating the LEASED BLOCK areas, you should also get a copy of the latest NOAA chart for the specific area which you are interested navigating in at least in 1:80,000 scale. The Tiger Shoals area is shown on NOAA Marine CHART 11349 ~ Vermillion Bay and Approaches. This chart will show the individual platforms in the area of coverage, underwater mounds, wrecks and other navigation features. The chart also shows underwater pipelines designated by a series of dots followed immediately with a small line.

They are in their self worth while investment for the offshore navigator. When getting these charts, be sure to get the latest version by (year) that is available. But historic charts created ten years or so age would also be a great value to you as they would show the well-platform as they were then.

Almost any NOAA contract Chart Mapping Service that has a print on demand service should be able to provide you with these charts.

The get the full use of the chart and the information you need, you can then access the Management, Regulation, and Enforcement (BOEMRE) web site @ http://www.gomr.mms.gov/index.html
Under the FAST FACTS ~ API List searching program, you can search by Leased Area, by Leased Block and well number or well name. You can even search for DATE THE WELL was closed or removed. The program will then produce all the data that meet your search criteria. Search in the PLATFORM STRUCTURE topic. Go to their web page at: http://www.data.boem.gov/homepg/data_center/platform/platform/master.asp

Select the Leased Area, then the Block number or just the removal date.
By noting the Leased Areas, you can select a specific area and even certain of the individual Blocks in the area for existing leases and or platforms. This program is a very valuable tool for the offshore fisherman.

After defining the area/block you are interested in the program will display all of the platforms in that area or block. They mostly just have a number of the platform, but sometimes indicate the common or given name of the facility, i.e. BRUTUS, RAM POWELL, etc. The position figures are usually stated in Decimal Degrees and were determined by using NAD 27 Datum. Once you have these positions you can then enter them manually into your GPS unit.

Again Remember, that the position format in your program or GPS unit, MUST agree with the MMS format or you MUST convert the decimal degrees into the format that you use in your unit or temporarily change the POSITION FORMAT in your GPS unit to Decimal Degrees and NAD 27 DATUM and enter the positions. Then change the Position Format and the DATUM back to the one that you normally use. The internal GPS software will do the conversion for you. This is extremely important when trying to find an underwater site that has no surface landmark.

By selecting the specific areas you will have all of the existing or removed platforms in that leased block

Now that you know HOW TO, I have taken the opportunity to plot SOME of the over 400 rigs and platforms in the area you indicated.

These clusters of rigs underwater mounds and wrecks are located in or on the Tiger Shoal area. Most of the platforms are of were located in North Marsh Island Leased Area blocks 208, 209, 210, 212, 230, 231, 232, 234, 235, 236, 237, 239, and The Vermillion Area Leased Blocks 30, 31,33, 50, 51, 52, 53, 69, 70, and 71. As previously stated, the area is crossed with numerous pipelines which in themselves offer fishing structure.

Here are some of the wells and other hazards objects in the Tiger Shoal. The
names of the sites were as to the type of feature the represent. The Tiger names are my designation of the well sites.
