Greenergy Terminals Limited was developing its facility in Teesside, to increase the offloading rate of ULSD at the jetty facility, and the storage capacity at the North Tees Marine Terminal (GMT).
The project was to enable ULSD to be transferred from the existing storage tanks to neighboring tanks at the Navigator and Inter Terminals. It required a minimum transfer rate of 1730m³/hr from the Jetty to transfer 52,000m³ within a 30 hour time period, however this did not include for any mooring, connection or de-mooring time.
We carried out a detailed investigation to specify new duty/standby 3.3kV transfer pumps from GMT to Navigator and Inter Terminals. We also had to understand if the existing pump bypass diameters could be increased to allow a greater flow from ship to shore in order to meet the 30 hour transfer time and remain within allowable pumping velocities.
After the investigation, 100m of existing 12” pipe line was replaced with a new 20” pipe line and an un-commissioned 10” pipe line installed in the Sembcorp pipe corridor was removed and upgraded to a 14”pipe line.
The pipe line extends through Navigator to Inter Terminals and way leaves were negotiated to install the extension using an existing section of previously installed 14”pipe line.
The pipeline routes within Navigator and Inter Terminals were defined along with the amount of storage capacity to be maintained. The existing 20” line used to unload ships was used to pump from the GMT storage tanks back towards Jetty 4 and connected to the new 14” pipe line installed to Navigator and Inter Terminals.
The GMT, road and rail tank overfill protection and level instrumentation was also reviewed and upgraded to meet current guidelines.
