RSS Courageous was on patrol off the waters of Pedra Branca on 3 January 2003 and was travelling on the eastbound lane of the Traffic Separation Scheme when she made a turn against the flow of shipping at 2325 hrs local time. A collision with ANL Indonesia subsequently took place at 2335 hrs.
A large-scale search-and-rescue operation was conducted 3 - 15 January by the Republic of Singapore Navy, the Police Coast Guard and Police and naval units from Indonesia.
Four female sailors were at the stern of the patrol vessel in their sleeping quarters, believed to have been asleep. ANL Indonesia was sailing to South Korea when her bow struck RSS Courageouss rear and sheared off the stern. The sailors were believed to have been killed instantly, and two of their bodies sank into the sea as the merchant ship backed away from the stern of the patrol vessel. Divers later recovered the body of CPL Goh Hui Ling lodged between the bunks after the vessel was put in dry dock at Changi Naval Base. The bodies of 1SG Heng Sock Ling[1] and 1SG Seah Ai Leng[2] [3] washed up on the Indonesian resort of Pulau Bintan and Sebong, north-west of Pulau Bintan on 5 January 2003.
The body of 2SG Chua Bee Lin was never found. Her body was originally believed to have been lodged in the stern of the patrol boat which broke off following the collision and sank on the seabed. A salvage team from Smit International successfully lifted the wreckage on 14 January 2003[4] but her body was not found.
In the investigation report released on 4 April 2003[5] by the Maritime and Port Authority of Singapore, it was revealed that RSS Courageous was under the immediate control of Lieutenant Chua Chue Teng, 23 who was a trainee Officer Of The Watch and was supervised by Lieutenant Ng Keng Yong, 27 at the time of the incident.
The findings of the investigations concluded three key errors of judgment that resulted in the collision:
The two officers were subsequently charged in court under Section 304A Penal Code, for causing death by a negligent act not amounting to culpable homicide and were found guilty and fined SGD$4,700 and SGD$8,000 by District Judge Tan Boon Gin. An appeal[6] was lodged at the High Court of Singapore but was dismissed by Chief Justice Yong Pung How on 13 August 2004.
Six officers from the Singapore Police Coast Guard's PH50 Hammerhead Shark coastal patrol craft were awarded the Police Medal of Valour at the National Day Awards Investiture on 5 November 2003 along with the Minister for Home Affairs Awards for Operational Excellence, a team award for all 39 officers on 3 April 2003.[7]
