FSRU Thermal Recirculation Modelling Analysis

Hoegh LNG AS (HLNG) was working with Egypt Gas (EGAS) to install a Floating Storage Regasification Unit (FSRU) at the liquid terminal facility located at Ain Sokhna Port in the Gulf of Suez. As part of that effort Hoegh retained RPS to assess the extent of the cooled water discharge plumes generated by the FSRU operation and the potential for recirculation of those discharges back to the FSRU intakes. RPS performed a 3D modelling study to simulate the effluent plume and its fate, and a 1-year field program to monitor temperatures in the port basin once the FSRU was operational.

Challenge

Three-dimensional circulation and temperature plume modelling is complex and prior to the Hoegh/RPS field program there was little or no field data for model forcing or verification. Real time field data collection in Egypt was difficult as there were many restrictions on communications systems and instrument deployment in the port, where numerous permits are required.

Solution

RPS applied its BFHYDRO 3D hydrothermal model to understand the longer term fate of the discharge thermal plume in the basin and the possibility for re-circulation. Modelling results indicated some potential for re-circulation. Once the FSRU vessel was in place, Hoegh retained RPS to design and implement a field program to monitor temperatures in the port basin. RPS developed and implemented a real time program to monitor the FSRU effluent and environs, that both Hoegh and RPS personnel could review on an ongoing basis, measuring temperature at 6 locations and 5 depths, currents in the entrance channel, tides in the basin, and meteorological conditions at the FSRU for a full year.
