Malaysia Detains Vessel Under New Anchoring Restrictions
A vessel was detained for approximately one month after anchoring and conducting an unauthorized ship-to-ship transfer within Malaysia‘s newly designated Marine Sensitive Area.
The incident occurred just two days after the new regulations took effect on September 11, and demonstrates the potential consequences for vessels operating in waters commonly referred to as “OPL Singapore” (Outside Port Limits Singapore).
According to Skuld, the vessel anchored within the designated area on September 13 and subsequently carried out an STS operation without the required permission from Malaysian authorities.
The P&I club warns that violations of the restrictions could result in prolonged vessel detention and substantial financial demands.
New Restrictions on Anchoring and Vessel Operations
As previously reported, Malaysia introduced Marine Sensitive Area Notice 01/2026 under the Exclusive Economic Zone Regulations 2026 to protect sensitive marine features and prevent pollution.
Under the official notice, anchoring is prohibited within the designated area, except during search and rescue operations, when anchoring is necessary because of vessel damage or when responding to specific pollution incidents. Cargo transfer operations, including STS transfers, require prior written government permission, while bunkering operations are prohibited.
Additional restrictions apply to vessel navigation, including a maximum speed of 12 knots and a prohibition on entry for cargo vessels and oil tankers exceeding 300 meters in length and 40 meters in width. Failure to comply with the protective measures constitutes an offense under the Exclusive Economic Zone Regulations 2026.
Enforcement Risks Highlighted
The incident highlights the enforcement risks associated with Malaysia‘s recently introduced Marine Sensitive Area (MSA). Skuld warns that waters commonly described as OPL Singapore should not automatically be considered available for anchoring or STS operations without verification of the applicable Malaysian requirements.
The P&I club advises owners, operators and masters to ensure that voyage planning, anchoring instructions and STS arrangements reflect the designated MSA boundaries and restrictions.
