Robert Allan Ltd. Tug for Royal Thai Navy

Italthai Marine, Thailand recently delivered H.T.M.S. Panyi, a Robert Allan Ltd. designed RAmparts 3200 class tug to the Royal Thai Navy. The tug was officially enrolled by Admiral Na Arreenich, the Naval Commander on March 27, 2017 in Bangkok.

Panyi was named after Ko Panyi which is a fishing village in Phang Nga, Thailand, notable for being built on stilts by fishermen and is a well-known tourist destination.

Initial feedback from all levels of the Navy suggests that the tug has been very well received.

The delivery of H.T.M.S. Panyi inaugurates the replacement program for existing tugs. The tug is responsible for handling larger vessels of the Royal Thai navy such as H.T.M.S. Chakri Naruebet and H.T.M.S. Similan. Other purposes include supporting operations such as Fire Fighting, Oil Recovery and beyond in navy ports, other ports and along the coast line.
