The U.S. Coast Guard is amending the requirements regulating personnel permitted to serve as a person in charge (PIC) of fuel oil transfers on an inspected vessel by adding the option of using a letter of designation (LOD) in lieu of a Merchant Mariner Credential (MMC) with a Tankerman-PIC endorsement.
Obtaining an MMC with a Tankerman-PIC endorsement is now optional for PICs of fuel oil transfers on inspected vessels. This change is not limited to towing vessels, but one effect of this rule is that a PIC currently using the LOD option on an uninspected towing vessel may continue to do so once the vessel receives its Certificate of Inspection.
This rule only addresses transfers of fuel oil. The PIC requirements in 33 CFR 155.710(a), (b) and (f) for vessels transferring cargo remain unchanged.
