Transfer Procedure

1. Selection of Suitable Location

A suitable location for the STS transfer is identified

2. Preparation and Planning

Both the receiving and supplying vessels must undergo thorough preparations

3. Positioning of Vessels

The vessels involved in the transfer maneuver into position alongside each other

4. Mooring and Connection

Once in position, the vessels are securely moored to each other using heavy-duty mooring lines

5. Transfer

The crude oil is pumped from the storage tanks of the supplying vessel to those of the receiving vessel

6. Monitoring and Safety

Throughout the transfer process, strict safety protocols are followed to minimize the risk of spills or accidents

7. Completion & Disconnection

Once the transfer is complete, the hoses or pipelines are disconnected, and the vessels are unmoored from each other
