U.S. Coast Guard: July 20 a significant date for Subchapter M regulations

The following is excerpted from an article posted July 20 on the U.S. Coast Guard's Maritime Commons Blog. The complete article is available online.

Towing vessels with keels laid or major conversions on or after July 20, 2017 are required to meet 46 CFR Subchapter M and obtain a Certificate of Inspection (COI) prior to operating.

Additionally, starting July 20, 2018, a portion of existing towing vessels will have one year to meet all of Subchapter M and obtain COIs. As discussed in Subchapter M, owners or managing operators of more than one existing towing vessel required to have a COI must ensure that each existing towing vessel under their ownership or control is issued a valid COI according to the following schedule:
  1. By July 22, 2019, at least 25 percent of the towing vessels must have valid COIs on board;
  2. By July 20, 2020, at least 50 percent of the towing vessels must have valid COIs on board;
  3. By July 19, 2021, at least 75 percent of the towing vessels must have valid COIs on board; and
  4. By July 19, 2022, 100 percent of the towing vessels must have valid COIs on board.
