How long is the service required for obtaining a PIC-DL endorsement on tank vessels?

To obtain a PIC-DL (Person in Charge - Dangerous Liquids) endorsement for tank vessels, the requirement is 90 days of service on vessels that carry dangerous liquids. This period is outlined by the U.S. Coast Guard regulations, which specify that the applicant must demonstrate a certain amount of practical experience to ensure they have the necessary knowledge and skills to manage the safety and operational aspects of handling dangerous liquids aboard these vessels.

The 90-day service requirement ensures that mariners gain adequate hands-on experience while also allowing for exposure to various aspects of operating tank vessels, including loading, unloading, and safety procedures. This experience is crucial, as it prepares them for potential challenges they might face in the operational environment of a tank vessel carrying dangerous cargo.

In this context, other timeframes, such as 60 days, 180 days, or a full year, do not reflect the established regulations for this specific endorsement, underscoring the importance of the precise duration of 90 days for obtaining the PIC-DL endorsement.
