Tankerman PIC: An Overview of the Person In Charge Endorsement
Tankerman PIC is the endorsement that makes a mariner legally responsible for cargo transfers on tank vessels. This overview explains the categories, requirements, and why it commands premium pay.
What Tankerman PIC Means
Tankerman Person In Charge (PIC) is the MMC endorsement authorizing a mariner to be the individual responsible for a cargo transfer on a tank vessel — the person who plans the lineup, supervises the operation, and is accountable for doing it safely. It is one of the most responsibility-heavy endorsements an unlicensed mariner can hold.
Cargo Categories
PIC endorsements are issued by cargo category — for example DL for Dangerous Liquid (petroleum and chemical products) and LG for Liquefied Gas. Your endorsement must match the cargo you're handling, so mariners target the category relevant to the vessels they intend to work. Barge units in the Gulf and inland petroleum trades most often need the DL category.
How You Qualify
Earning PIC generally requires qualifying sea time aboard tank vessels, a USCG-accepted tankerman training course, documented supervised transfers, and a written examination. The Tankerman-Assistant endorsement is a common stepping stone that lets you conduct transfers under supervision while you build toward PIC.
Why It Pays a Premium
Because transfers are high-liability operations and qualified PICs are essential to keep liquid-cargo vessels running, the endorsement reliably adds to a mariner's day rate. On petroleum barge routes it's one of the clearest ways for an unlicensed mariner to increase earnings, and pairing it with a towing or deck license multiplies its value.
Staying Qualified
The endorsement rides on your MMC, so it depends on keeping your credential and medical current. Employers frequently layer their own transfer-competency sign-offs on top of the USCG endorsement. Keep transfer documentation organized, because both the NMC and your employer may want to see a record of your recent operations.
A note on requirements
Credentialing rules change and often depend on your specific vessel, route, tonnage, and history. Nothing here is legal advice. Always confirm the current requirements with the USCG National Maritime Center (NMC) and with your employer or vessel operator before making career or hiring decisions. When a rule seems to conflict with your situation, an NMC deficiency letter or a call to the NMC Customer Service Center is the fastest way to get an authoritative answer.
