The Malaysia Maritime Enforcement Agency (MMEA, or Malaysian Maritime) on Tuesday (25 May) said it has arrested two offshore supply vessels over an illegal ship-to-ship (STS) oil transfer operation at the waters around Kemaman port.
A MMEA patrol boat detected the two ships approaching each other in a suspicious condition around 3.4 nautical miles from Kuala Kemaman and an arrest was made to the parties at 11.30am (local time) on Monday, said Kemaman Maritime Zone Director, Maritime Commander Rashidilhadi bin Abd Rashid.
