With effect from 11 September 2026, Malaysia has established a Marine Sensitive Area (MSA) and designated fairways at the eastern approaches to the Straits of Malacca and Singapore. The measure is set out in Marine Sensitive Area Notice 01/2026 and is intended to protect the environment.
A speed limit of 12 knots applies within the MSA. Cargo vessels and oil tankers exceeding both 300 meters in length and 40 metres in breadth are not permitted to enter. Anchoring and bunkering are also prohibited. Activities within the area require permission from the Malaysian Government.
The Malaysian Maritime Enforcement Agency (MMEA) may board vessels to check compliance with the rules and confirm that the required permissions are in place. Vessels without these permissions may be detained. Breaches may also lead to prosecution and reportedly carry fines of up to MYR 1,000,000 (approximately USD 245,000 as of 14 October 2026).
It remains unclear how the authorities will apply the rules to vessels transiting the area without calling at a Malaysian port. The MMEA has, however, previously detained and fined vessels for anchoring in Malaysian territorial waters without permission. In some cases, vessels were released only after financial security had been provided.
We advise Members operating in the area to:
- take the MSA into account when preparing voyages, drawing up passage plans and assessing operational risks;
- inform masters and crew of the restrictions;
- contact local agents in good time and, where necessary, the Malaysian authorities;
- use designated anchorages where possible and keep up to date with further enforcement guidance.
