Course Comparison
Tank Ship Dangerous Liquids: Everything You Need to Get Certified
No. Our course gives students a Tank Ship Dangerous Liquids endorsement but it does not qualify students for the LG (liquified gas) endorsement.
The Tank Ship Dangerous Liquids course is a 5 day course that covers slightly more material than the Tank Barge-PIC course. As a result, students who take and pass the Tank Ship Dangerous Liquids course and have the relevant sea time can apply for Tank Assist, Tank Ship-PIC, Tank Barge-PIC, and Tank Ship Dangerous Liquids endorsements.
The Tank Barge Person In Charge (PIC) is responsible for the safe and compliant transfer of liquid cargo. Their duties include pre-transfer planning, overseeing cargo transfer operations, emergency response, and regulatory compliance.
