Heightened enforcement against illegal anchoring in Malaysian waters

Posted: 06/08/2025

In recent years, Malaysia has intensified its surveillance and enforcement efforts to address growing concerns over unauthorised activities within its waters. 

One key focus is illegal anchoring which has led to the detention of dozens of foreign flagged vessels, fines and, in some cases, reputational damage for the vessel owners. 

A new era of strict enforcement

In July 2025 the Malaysian Maritime Enforcement Agency (MMEA) and the Malaysian Marine Department reaffirmed their zero-tolerance approach to unauthorised anchoring. 

The MMEA is also commonly referred to as the APMM (Agensi Penguatkuasaan Maritim Malaysia). 

The MMEA and Marine Department issued fresh warnings, heralding a crackdown on unauthorised maritime activity, including illegal anchoring and ship-to-ship (STS) transfers. Notably, this move follows a series of high-profile detentions involving bulk carriers and tankers that failed to obtain proper anchorage permits. Some were even unaware that they had entered restricted waters. 

At the same time, the authorities reaffirmed the requirement for all vessels to keep their AIS (Automatic Identification System) switched on at all times while in Malaysian waters.

Framework

Malaysia regulates anchoring under various statutes, shipping notices, port circulars and technical circulars issued by the MMEA and Marine Department.

Vessels may only anchor in designated areas with prior approval from the Marine Department.

Violations can result in detention, fines and criminal liability for the master and shipowner.

Implications of illegal anchoring in Malaysian waters

• Immediate detention: vessels found at anchor without valid authorisation may be boarded and detained and, in some cases, escorted to port.
• Fines and penalties: monetary penalties may reach up to RM 100,000 (approximately USD 21,000) per offence or imprisonment for responsible individuals.
• Operational delays: detained ships may be held for extended periods, disrupting operations, and leading to potential exposure under charterparties.

Practical recommendations

• Ensure anchoring occurs only in designated zones with official approval.
• Submit timely applications for anchorage and STS activities with clear documentation of intent and purpose.
• Keep AIS active at all times, as required, and promptly notify the Marine Department if temporary deactivation is necessary.
• Educate bridge and operations teams on local laws and consequences of non-compliance.

Conclusion

Malaysia's maritime enforcement posture reflects a broader regional trend of coastal states asserting their jurisdictional rights over their waters. Shipowners, charterers and operators must remain vigilant, as ignorance of local laws offers no defence.
