Dangers of closing ship valves against shore flow

06 Oct 2022 / Saudi Arabia

The Saudi Arabian Oil Company (Saudi Aramco) has issued a warning highlighting the serious dangers associated with restricting shore cargo flow by either closing the ship’s valve against the flow and/or by reducing the number of tanks available without notifying the berth supervising operator in ample time.

There is an increasing trend in the number of pressure surges and Emergency Shut Down (ESD) activation as a result of a ship restricting the shore flow.

Such practices have previously resulted in pressure surges and substantial damage to the pipeline system of the Terminal. Additionally, the entire Terminal loading system will shut down.

Any vessel contributing to a pressure surge and subsequent ESD will be subject to removal from the berth. Further, once removed, the vessel will be directed to anchorage until:
- A full and comprehensive investigation has been completed.
- An inspection of all pipelines and fittings has been completed, including subsea.

It is the Terminal’s policy to seek recompense to the full extent permitted by law for all costs incurred by negligence and fault of any party. Including:
- Charges for double berthing.
- All costs associated with inspection of all pipelines and fittings including subsea.
- All costs associated with pipelines and fittings’ repairs.
- Any other costs resulting from disruption to cargo operations.

Additionally, the vessel will be flagged in the Port & Terminal Management System on departure and subjected to stringent vetting requirements during future visits and potential banning if further serious safety or operational deficiencies are committed.

Ship Owners are encouraged to remind all vessels that they are mandated to take all actions in line with safe shipboard SMS practices and as stated by Saudi Aramco Ports and Terminals Rules and Regulations and ISGOTT relative to communications, valve operations, topping off procedures and pressure surges. These preventative actions are to be included in the vessel loading operations plan and followed throughout the vessel’s port stay.
