The Vessel Traffic Service (VTS) Wilkinson Point Watch will be temporarily stood down from 6:00 pm Monday, February 11th, 2019 until 6:00 pm Sunday, February 17th, 2019.  The following measures remain in effect:

Port Allen Lock MM 219-229 AHP LMR:

1.  All vessels are required 1 horsepower (HP) per 5 tons or 280 HP per regulation loaded barge for canal tows entering/exiting the Locks. Empty barges may be calculated at ½ the horsepower requirements to that of a loaded barge when computing the overall horsepower requirement. VTS may on a case-by-case basis grant exemptions to this requirement based on conditions and size of tow.
2. All tows exiting PAL into LMR intending to turn northbound shall use an assist vessel of at least 1200 HP, or proceed south to MM 221 to top around unassisted.
3. All tows >600 feet (excluding towboat) entering and exiting the lock must use an assist vessel with a minimum of 1200 HP and when topping around between MM 229-221.
4. If unable to meet the horsepower-to-ton requirements and obtain alternative permissions from the VTS, then an Assist Vessel is mandatory for entering or exiting the Locks.

Wilkinson Point MM 232-237 AHP LMR:

1. The Towing Assist Vessel (TAV) is no longer assisting tows around Wilkinson Point.
2. All vessels are limited to a max tow size of 30 barges with 280 HP per barge for downbound transits within this area. 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 Wilkinson Point. 
3. An 8000 HP towing vessel is authorized to push a 30 barge tow (400 HP less than the requirement stated in paragraph 1 above).  
4. All downbound traffic is required to flank WilkinsonPoint.  The only exception to the flanking requirement are tows pushing 1 loaded barge or 2 empty barges.  
5. No more than two downbound vessels will be allowed below Thomas Point (MM 240) at any time regardless of tow size.
6. All downbound traffic will transit Wilkinson Point during daylight hours only. Harbor Fleet Tows of one load or two empties are exempt from daylight only restrictions.

8. Vessels shall not meet or overtake between MM 232 to MM 237.
9. Tank barges shall be placed in the most protected position in the tow makeup.
10. All tows shall be squared off. No spiked barges shall extend greater than 50 feet beyond the head of the tow.  All towing companies should use their most experienced crews.
11. Tows transiting Wilkinson Point pushing one loaded standard barge or two empty standard barges are exempt from daylight only restrictions. 

Tows Topping Around between Duncan Point and the HWY 190 Bridge including Harbor Fleet Tows MM 221 - 234:

1. Tows greater than 300 feet in length must use a minimum 1000 HP Private Assist Vessel when topping around.

Ocean Going Vessel requirements, Baton Rouge Harbor (MM 225-234):

1. Ocean going vessels must use tug escorts with adequate horsepower alongside while transiting upbound past the I-10 Bridge to dock, as well as departing the dock and transiting downbound past the I-10 Bridge. 
2. Only one ocean going vessel at a time will be allowed to be underway between the I-10 Bridge and the US-190 Bridge.
