Mott MacDonald has been appointed to design the sea water intake, outfall and circulating cooling system for a 500MW power plant in Bhavnagar in the state of Gujarat, India.
The lignite-fuelled thermal power station, owned by Bhavnagar Energy Company Limited (BECL), is being developed to meet increasing power demand.
Cooling water for the power plant is being provided by drawing sea water from the Gulf of Khambhat, 5km to the south of the plant. Infrastructure company MARG is Mott MacDonald’s client for the scheme. MARG is designing, procuring, constructing and commissioning the INR2,400m (£29.3m) sea water intake, outfall and cooling water system for BECL. Mott MacDonald will undertake detailed engineering of the sea water intake system, circulating cooling water system, and onshore and offshore pipelines.
Mott MacDonald‘s project director Ramesh Kumar said: “As a design consultant for this project we are adopting 3D modelling for analysis and design. This will give us a more realistic approach which will allow us to develop optimal solutions.”
He added that in addition to the detailed design work Mott MacDonald is also undertaking wave modelling and sedimentation study. “This will give us crucial information of the wave behaviour in the Gulf of Khambhat, known as one of roughest seas in the world, and its effect on the offshore bund structure,” he said. “This will allow us to optimise size quantity and consequently cost of armour stone units to be used in the bund.”
