The Malaysian Maritime Authorities are intensifying their efforts to combat illegal maritime activities, specifically focusing on unauthorized anchoring and ship-to-ship (STS) transfers. Given its proximity to the busy Singapore Strait, Malaysia’s waters have become a hotbed for such illicit activities, prompting the implementation of stricter regulations.
New Regulations for Vessels
Effective from the end of July, the Malaysian Marine Department has implemented new rules to curb illegal anchoring and transfers. A key measure is the requirement for all vessels to maintain their Automatic Identification System (AIS) transmission at all times. The authorities will be actively monitoring for any ships that “go dark” by turning off their signals. Additionally, ships must obtain a dual permit to anchor in key eastern areas near the Singapore Strait, which are particularly susceptible to these unlawful activities. This requires vessels to submit a detailed anchoring plan for approval from the Marine Department before entering the designated region.
Increased Enforcement and Detentions
Malaysian authorities have been instructed to heighten their vigilance. They have issued a strong warning that any ships found without the necessary documentation and anchoring approval will face detention. Officials are particularly focused on the waters east of the peninsula, which are known to be frequented by “shadow tankers” from Russia or Iran attempting to conceal their cargo.
This increased vigilance has already led to several detentions. On July 11, 2025, the Malaysian Maritime Enforcement Agency (MMEA) discovered two tankers alongside each other and seized 169,000 liters of diesel oil. The crew of the two ships, which included Indonesian, Indian, Myanmar, and Vietnamese nationals, were found with some members lacking valid identification. In another recent case, a Barbados-registered tanker with a crew of 18 Indian nationals was detained for illegally anchoring in Batu Pahat waters.
