Malaysia bans bunkering and big ships in new sensitive area off the Singapore Strait
Marine Sensitive Area Notice 01/2026 caps speed at 12 knots and bars cargo ships and tankers over 300 metres from waters the industry calls OPL
Malaysia has closed a stretch of water at the eastern approaches to the Straits of Malacca and Singapore to bunkering, most anchoring and the largest cargo ships and tankers. The restrictions come from Marine Sensitive Area Notice 01/2026, announced on 10 September and in force since 11 September, which sets up a Marine Sensitive Area and designated fairways near the eastern end of the traffic separation scheme. Its appendix gives the boundaries and lanes as WGS84 coordinates.
The legal basis is Malaysia's Exclusive Economic Zone Regulations 2026, gazetted on 26 June and in operation since 29 June.
Inside the area ships may not exceed 12 knots. Cargo ships and oil tankers more than 300 metres long and more than 40 metres wide may not enter at all. Anchoring is allowed only for search and rescue, because of damage to the ship, or in specified pollution emergencies. Bunkering is prohibited, subject to exceptions listed in the regulations, and cargo may be transferred only with written government permission. Dredging, salvage, construction, and laying or repairing cables and pipelines need approval, as do research, seismic surveys and seabed mining. Fishing requires approval from the Department of Fisheries under the Fisheries Act 1985.
Why does it matter for OPL operations?
The rules cover waters that the shipping industry commonly treats as Outer Port Limits, where ships wait, take bunkers and transfer cargo outside port limits. Malaysia does not recognise OPL status in waters it considers Malaysian, including parts of both straits. Ships there must report their activities, anchoring included, to the Malaysian Marine Department and can be boarded and inspected. A ship that cannot produce the department's approval when inspected by the Malaysian Maritime Enforcement Agency may be detained.
Gard has warned that the rules could change westbound routing, with some ships staying south of the area before turning towards the westbound lane instead of joining the traffic flow further east. Citing its local correspondent Spica, the insurer put penalties at up to MYR 1 million, about $244,000. A ship can also be detained where a breach causes or threatens a discharge that damages Malaysia's EEZ or continental shelf, and a bond of up to MYR 1 million may be required for her release, separate from any fine. The notice applies to owners, masters and agents alike.
