Key Competency
Manage loading / discharge activity by carrying out roles and responsibilities of Shore Officer.
Skills (Discharge) (loading)
By the end of this course trainees should be able to:
Prepare for the loading / discharging of cargo. This includes the mechanics of discharging cargo or loading cargo from the ship to the terminal’s tanks or vice versa.
Page 22
Confirmations
This process involves the following procedural steps:
Step Action
1 Confirm, based on results from the Product Testing Officer, that the products to be discharged are acceptable: that is, within the acceptable limits compared to the ‘Certificate of Quality’ received from the ship.
2 Calculate the Wharf / Jetty / Dock to compound interface arrival times.
3 Check Wharf / Jetty / Dock to ship hoses / load arms are properly connected and supported.
4 Confirm pumping pressures and preferred order of discharge with the Wharf / Jetty / Dock Attendant.
5 Line-up and check that the correct valves are open at the manifold and thaks.
Determine for Port Perfect:
1. That the product on arrival is on-grade
2. The interface arrival time
3. Product to be first discharged
4. Start pumping pressure
5. Valves to open
6. Tanks receiving product.

What information and instructions do you give to the Wharf / Jetty / Dock Attendant when you are satisfied that the conditions are met and calculations are completed? What are the risks and consequences involved in this process?

Commence Pumping
Key Competency
Initiate commencement of pumping
You ask the ship’s Chief Officer to commence pumping and wait on advice from the Wharf / Jetty / Dock Attendant.
What does the Wharf / Jetty / Dock Attendant do and have to tell you after the ship starts pumping?
When filling out the Wharf / Jetty / Dock Attendant / Tank Compound Log it is vital to record on the hour and reconcile the quantities received with the ship’s records of quantities discharged.
Record the first entries for Port Perfect on:
1. Wharf / Jetty / Dock Attendant Log
2. Tank Compound Log
(See Attachment 1.)

Commence Loading
Key Competency
Undertake required checks and receive required confirmations prior to commencing loading
The commencement of loading is done in three parts:
1. Confirmations
2. Commence pumping
3. Hose and pipeline checks.
Confirmations
This process involves the following procedural steps:
Step Action
1. Confirm, based on results from the Shore Tank that is to be drawn from, that the products to be loaded onto the ship are acceptable; that is, within the acceptable limits compared to the ‘Certificate of Quality’ received from the Lab.
2. Communicate to the ensure the Movements Dept. and Wharf / Jetty / Dock attendants have the latest loading plan.
3. Communicate and confirm with the Chief Officer and discuss the loading plan and ensure that all is involved, understand the loading procedure and maximum flow rates.
4. Confirm with Wharf / Jetty / Dock attendant that the Wharf / Jetty / Dock to ship hoses are properly connected and supported to the correct loading manifold as per agreed loading plan.
5. Line-up correct Shore Tank as per plan and select appropriate pump as per loading plan loading rates.
6. Request ship to line up to receive cargo and open their manifold valves.
NOTE: Keep Shore manifold closed.
7. Request ship to notify the Wharf / Jetty / Dock attendant when they are lined up and ready to start pumping.

If the procedure on the previous page was not followed, list some of the risks and consequences.

Commence Pumping
Key Competency
Initiate commencement of pumping
The ship’s Chief Officer has advised the Wharf / Jetty / Dock attendant that he is lined up valves open and ready to commence receiving cargo.
List and explain the next steps, and what does the Wharf / Jetty / Dock Attendant do and have to tell the ship after the shore starts pumping?
Page 28
Wharf / Jetty / Dock Hose and Pipeline Checks
Key Competency
Undertake checks of hoses and pipelines
Complete records of pumping process
Checking
Explain:
1. Hoe regularly the pipelines and hoses are checked, and who checks them.
2. How submarine lines are checked.
3. Action taken when there are abnormal changes in pipeline
4. The possible consequences of an undetected leak in the pipeline or hoses.
Page 29
Flow Rates
The factors that affect the flow rate and must be considered are:
Ship’s pumping pressure and capacity to pump at required pressures
Pipe diameter
Pipeline length (capacity)
Previous records of loading / discharge
Data provided by the ship.
Ship’s receiving rate and pressure (loading)
List the conditions that will allow high flow rates or cause low flow rates.
High Low
Page 30
Flow Rate and static
The faster the pumping flow rate the sooner the loading / discharge is over. However, there are a number of precautionary conditions which have to be considered before the maximum flow rate can be reached.
List and explain the conditions which must be met before pumping can be increased to maximum flow rate.
Inspection of Tanks
List the checks needed for the various types of tanks after pumping has commenced into that tank, noting the intervals the tanks must be checked when receiving product.
