HIGH WATER SAFETY ADVISORY:

Updated Reporting Procedures for the VTS Measure at Wilkinson Point (Above 38′)

When the Baton Rouge gauge reads above 38′, a U.S. Coast Guard Vessel Traffic Service (VTS) Measure is established in accordance with the Navigation Safety Regulations, Code of Federal Regulations Title 33, Subpart 161.11, for Wilkinson Point, Lower Mississippi River (LMR) from Mile 232 Above Head of Passes (AHP) to Mile 237 AHP. This VTS Measure is needed to protect persons and vessels from the potential safety hazards associated with the effects of high water levels on the Lower Mississippi River. This Measure is effective immediately with the following provisions:

1. All vessels are limited to a max tow size of 30 barges with 280 HP per standard barge and 650 HP per oversize barge for southbound transits within the Wilkinson Point special area. For the purpose of this calculation, barges with dimensions 290′ x 50′ or larger are considered “oversize” while barges with dimensions less than 290′ x 50′ are considered “standard.” If one of the barge dimensions (length or width) meets or exceeds the 290′ x 50′, then the barge is considered “oversize.” Empty barges may be calculated at ½ the horsepower requirements to that of a loaded barge when computing the overall horsepower requirement. Vessels unable to meet the HP requirements must make adjustments to meet the requirements prior to transiting the Wilkinson Point special area. Towing vessels with Z-drive propulsion types may be treated as having a horsepower 20% greater than the engine’s rating for the purpose of this calculation.
2. Effective 0600 on March 23, 2020 VTS LMR will no longer manage the vessel queue at the Wilkinson Point special area. All Towing Assist Vessel (TAV) rules remain in effect.
3. All down bound traffic will transit Wilkinson Point during daylight hours only and will utilize the TAV (min 5000 HP). Vessels pushing more than one loaded barge or two empty barges are required to flank, not steer, Wilkinson point.
4. The following exceptions apply only to harbor fleet tows: Vessels pushing four barges or less are not required to utilize the TAV, but must coordinate transits with the TAV. Vessels pushing one loaded or two empty barges may transit at night.
5. The TAV must meet the southbound vessel no lower than 2000 feet above Wilkinson Point. The TAV will position itself alongside the most appropriate agreed upon location on the barge tow after consultation with the vessel’s captain.
6. The TAV will then confirm information of current reaction above, around and below Wilkinson Point.
7. The TAV will discuss what the last vessel that transited Wilkinson Point found and continually brief southbound vessels of present position in correlation with the last vessel that transited.
8. The TAV will make corrections to the southbound vessel’s positioning if necessary.
9. No more than two southbound towing vessels will be allowed below Thomas Point at any time regardless of tow size.
10. There will be a LOMRC representative onboard the assist vessel with pilots on scene to ensure safe navigation. The TAV captain/pilot may satisfy this requirement provided they are familiar with this Waterway’s Action Plan and the current MSIB.
11. Up bound traffic may transit Wilkinson Point any time during which the queue is empty of down bound traffic. Passenger vessels will have a priority position in the queue.
12. Up bound vessels unable to average 3 MPH around Wilkinson Point must use a Private Assist Vessel (PAV).
13. Vessels are prohibited from meeting or overtaking other vessels from MM 232 AHP to MM 237 AHP.
14. Tows shall be squared off. On tows with five or more barges, there shall be no spiked barges that extend 50′ beyond the head of the tow.
15. All down bound tows shall have tank barges placed in a protected position in the tow makeup (not on the head of the tow or on either outboard string).
16. All down bound tows entering Baton Rouge Harbor (Devil’s Swamp) with more than one barge attached shall hire a private assist vessel (PAV) to accompany them into the harbor.
