Robert Allan Ltd. RAmparts 3200 Tug for Royal Thai Navy

May 29, 2017

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. The name was given by King Rama IX (King Bhumibol Adulyadej) and was marked the last vessel of the Royal Thai Navy named by His Majesty.

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.

The tug has been designed and built to the following notation of Lloyd’s Register:

The vessel has been arranged and outfitted to high standards with twenty (20) crew berths in total. The commanding officer’s cabin and a two-officer cabin are located in the deckhouse; cabins for other officers and crews located on the lower accommodation deck. Fully appointed mess/lounge for officers and crews are arranged in deckhouse respectively near a modern fully-equipped galley.

Main propulsion for the tug consists of a pair of MTU 16V4000M54 diesel engines, each rated 1,685 kW at 1,800 rpm, and each driving a Schottel SRP 1212 fixed pitch Z-drive unit, in ASD configuration.

The electrical plant comprises two (2) identical diesel gensets, each with a power output of 200 ekW.

The deck machinery consists of one ship-assist hawser winch forward, and one tow-hook on the aft deck for coastal towing service. Ship-assist service will be carried out through a specially designed staple which accommodates a fairlead. A capstan and a deck crane are also provided on the aft deck.

The wheelhouse is designed for maximum all-round visibility with a forward control station providing maximum visibility to both fore and aft deck working areas.

Ship-handling fenders at the bow consist of two rows of cylindrical fender, 800 x 400. A 500 x 450 “W” block fender is arranged below the cylindrical fenders. 300 x 300 hollow “D” fenders provide protection along the forecastle deck and the main deck sheer lines, and similar “D” fender is used at the stern.
