HTMS Similian (AOE 871) replenishment oiler

In 1993, Thailand wanted to buy a new replenishment ship for its light aircraft carrier group. China won this project. With the technological preparation before and concepts from Ukraine replenishment ship, the construction of HTMS Similan was very successful and the ship was provided to Thailand Royal Navy in August 1996.

The Royal Thai Navy counter-piracy task group is part of the multi-national Combined Task Force 151 (CTF-151). CTF-151 was established in January 2009 as a multi-national counter-piracy task force. In conjunction with NATO and EU Naval Force (EUNAVFOR), ships from CTF-151 patrol in the Somali Basin and the Internationally Recommended Transit Corridor (IRTC) in the Gulf of Aden. CTF-151 also supports the Best Management Practice methods which are promoted to the shipping industry for the avoidance of piracy. CTF-151 is one of three task forces operated by Combined Maritime Forces (CMF), a global maritime partnership, dedicated to promoting security and prosperity across some 2.5 million square miles (6.5 square kilometres) of international waters in the Middle East. CMF's main focus areas are countering terrorism, preventing piracy, reducing illegal activities, and promoting a safe maritime environment.

Two Thai naval ships, the offshore patrol vessel, HTMS Pattani, and support ship, HTMS Similan, disrupted pirate activities in the Gulf of Aden, adding to maritime security and the protection of legitimate merchant vessels within the region. At 7 A.M. on Oct. 23, 2010, the MV Merlin Arrow issued a distress call stating that it was being attacked by a fast skiff. Indian warship INS Rajput, which was protecting a convoy in the area, sent its helicopter to investigate the skiff, which quickly changed course and headed away.

HTMS Similian and HTMS Pattani were in the vicinity conducting another convoy when Similan spotted one skiff approximately 2 miles away. Six people were seen on board with a long ladder, and the skiff was suspected as being the same that had previously attacked MV Merlin Arrow. HTMS Pattani was ordered to continue escorting the convoy, whilst HTMS Similan sent her helicopter, Stingray 1, to pursue the suspicious skiff. A ladder and unidentified objects were seen being dropped into water as the skiff was attempted to escape. Stingray 1 used smoke floats to warn the skiff to stop. HTMS Similan's boarding teams were dispatched to investigate and found six people on board with sufficient stores to sustain them at sea for several days, as well as GPS navigation equipment. The boarding team took photographs and personal details of the skiff's crew. The skiff's GPS navigation system was seized for further investigation and the suspected pirates were returned to Somalia.

Later the same day, HMTS Similan was informed by another merchant vessel, MV Karachi, that two whalers and a skiff had been sighted nearby. No national flag or fishing gear were visible, so HTMS Similan again went to investigate and signalled the whalers to stop. HTMS Similan reported seeing objects were seen being thrown into water from the whalers. After the whalers had stopped, HTMS Similan sent out its boarding teams. In total, there were 14 people and enough fuel, food and water to sustain themselves at sea for at least a week, as well as four grappling hooks. Once the boarding team had completed their investigation, the whalers were driven out of the Internationally Recommended Transit Corridor with enough fuel to return to shore.

Upon completion of the successful operation Rear Admiral Chaiyot Suntaraga, Thai Navy Task Group Commander, stated, "I am proud of the professionalism of my team in helping to prevent piracy within the Gulf of Aden. The Combined Task Force 151, of which HTMS Similan and HTMS Pattani are both supporting, is committed to providing maritime security to the Gulf of Aden and Somali Basin. This is our first counter-piracy operation and I am pleased that the disruptions went well."

Commander of Combined Task Force 151 (CTF-151), Turkish Rear Admiral Sinan Ertugrul stated, "HTMS Similan and HTMS Pattani have prevented acts of piracy within this busy and globally important sea lane. Their commitment to the task is superb and the way in which they conducted themselves in this tense situation is first-class. We must remember that piracy is a truly a global problem and I am pleased to be here leading the multi-national coalition, Combined Task Force 151."

Two Royal Thai Naval ships, Auxiliary Oiler Replenishment Vessel HTMS Similan and Offshore Patrol Vessel HTMS Pattani, belonging to the Royal Thai Navy Counter Piracy Task Group (RTNCPTG), arrived at the Port of Colombo on 19 September 2010. Commander of the Sri Lanka Navy Vice Admiral Thisara Samarasinghe visited the Royal Thai Naval ship, HTMS Similan at the Port of Colombo yesterday (21st September 2010). On arrival, he was accorded a Guard of Honour on board HTMS Similan and was warmly received by Commander, Frigate Squadron 2 of the Royal Thai Fleet and Counter-Piracy Mission Commander Rear Admiral Chaiyot Sundaranaga and the Ship's Commanding Officer Captain Poollarp Tattathongkom. The Commander of the Navy made a tour on board the ship and was briefed by the Mission Commander and the Ship's Commanding Officer on their counter-piracy mission in the Gulf of Aden. Thereafter, he was hosted for lunch and it was followed by an exchange of mementos.
