Master of Freight and Towing Vessels Upon Oceans 1600 tons - TOAR Question

I have a current 1600 gt oceans master’s license. I have not sailed on it since 1985. It has been renewed every five years - It it NOT renewed for continuity; it was actually renewed and is good to sail on, but since I never took an STCW class, it is only good for 200 miles offshore.

I am going back to sea again. I will take all the STCW courses I need, but I don’t get the TOAR requirement. My previous license was Master of Freight and Towing Vessels Upon Oceans 1600 tons. As master I have towed drilling rigs all over the world, including a tow from Louisiana to Singapore. What’s the most painless way I can get a towing endorsement so I can tow offshore or anywhere else?
