Plymouth Marine Laboratory (PML), University College London and Protein Technologies appointed Bouygues Energies & Services as the high tech engineering partner responsible for the unique design & build modular solutions of a semi – industrial scale first of kind photo bioreactor with integrated feed tanks, control and monitoring systems.


Bouygues Energies & Services project delivery strategy was to design and build, fully tested, preassembled, prewired and commissioned photobioreactor units mounted on a skid frame to enable ease of transport and deployment in diverse applications around the world.


Bouygues Energies & Services’ process engineering teams performed detailed process design calculations from first principles based on the physical and chemical parameters required for growing microalgae, but more importantly ensuring the optimised conditions within the photobioreactor to ensure favourable condition for algal growth.


As part of highly original and innovative design, Bouygues Energies & Services developed a straight single tube photobioreactor compared to the conventional coiled photobioreactor on the market. Our design provided better flow control access each of the individual growth tubes to provide a more robust and resilient design.


Following approval of the innovative concept design by the academic partners, Bouygues Energies & Services prepared 3D visualisations and fabrication drawings for manufacturing at our off site prefabrication facility in Knowsley, Liverpool.


Benefits to Client:
