LNG PIC Question

Hello, I have my Tankship PIC and have sailed on tankers. I am curious about taking an LNG PIC class. My question is : would I get the LNG PIC endorsement right away or would i have to go out as an observer? Do i need to get loads and discharges again? I’ve done all that already to get my Tankship PIC.

See 46 CFR 13.203. You need service on a LG tank ship as either an officer, cadet, or rating. Time as an observer is not acceptable.

The transfers and service are less if you already hold a PIC endorsement for DL tank ships.
