Final Anchorage Operational Guidelines (2024):
1. Anchoring Procedures:
– Minimum scope: 5:1 (normal), 7:1 (typhoon)
– Position keeping: AIS mandatory (Class A transponder)
– Anchor watch: Continuous bridge watch (hourly position logs to Port Control)
– Dragging alarm: Required (50m radius setting, independent power)
2. Safety Requirements:
– Emergency equipment:
* Both anchors ready to deploy (tested monthly)
* Engines on standby (15 min notice, weekly test)
* Updated position reports (hourly to Port Control)
– Prohibited activities:
* Tank cleaning (all categories)
* Cargo operations (except emergency)
* Unauthorized transfers (fuel/water)
3. Commercial Regulations:
– Anchorage fees:
* Standard: $0.08/GT per day (+5% VAT)
* Special zones: +15-25% surcharge
* Emergency: No charge
– Advance notice: 24 hours required (48hrs for VLCC)
– Priority system:
* 1. Emergency vessels
* 2. Scheduled arrivals (container/bulk)
* 3. Others by ETA
4. Environmental Restrictions:
– No discharge of:
* Ballast water (without IMO-approved treatment)
* Sewage (within 12nm)
* Oily mixtures (any quantity)
– Protected marine areas:
* Coral zone (500m buffer – No.2/3)
