This Marine Safety Advisory is to ensure mariners, marine employers, and sponsoring organizations are informed of recent changes to the Department of Transportation Drug Testing requirements. As the U.S. Coast Guard requires a DOT drug test, this MSA seeks to broadly communicate important changes effecting mariners, marine employers, and sponsoring organizations.
The Coast Guard published Marine Safety Advisory 17-16 to bring attention to a problem with cracks on the cooling jacket, specifically MAN B&W, that have been linked to steering and propulsion casualties. All vessel owners, operators and engineers are encouraged to view this alert.
