Under Keel Clearance (UKC): A mandatory minimum UKC of 3.5 meters must be maintained at all times for Deep Draught Vessels (DDVs) and VLCCs.
STRAITREP Reporting: Mandatory reporting to Vessel Traffic Services (VTS) when entering designated sectors (Sectors 1–9). The Malacca and Singapore Straits remain two of
High Vigilance Areas (HVAs): Identifying zones with high collision risk, such as the Philip Channel and areas near Horsburgh Lighthouse.
