At Mott MacDonald, we have developed extensive knowledge and
experience of pumping stations and networks in the course of our
worldwide work in the fields of irrigation, water supply, public
health engineering, flood control, drainage, groundwater
abstraction, and urban development.
We have experience in all the phases of seawater cooling projects,
including initial feasibility studies, Front End Engineering
Document (FEED) Engineering, production of associated Procurement
Package Documentation, and finally Construction Supervision on
site.
Previous initial feasibility studies have reviewed the fundamentals
of seawater cooling system design and expansion, including:
- Conveyance system: pipework, canal, tunnel
- Pipework material study
- Pipework above ground or below ground
- Pipework conveyance formation - tree or loop
- Direct or indirect cooling (of end product by seawater
coolant)
- Once-through cooling system or a recirculation (including
cooling towers) cooling system
- Limitation of bio-fouling of conveyance infrastructure
- Maximise flexibility of system to accommodate future changes in
cooling water requirements by end-users (looking forward 20 – 30
years)
- Phasing of infrastructure construction, assisting to reduce
overall NPV costs
- Reliability study, to confirm the reliability and availability
of the overall system
- Steady state cooling water conveyance system modelling, to
confirm system capacity parameters (pipework numbers and diameter,
hydraulic pressures at various points in network) required for
specified cooling water flows
- Transient surge pressure modelling to confirm necessary surge
suppression equipment.
As part of the initial feasibility study optioneering, the
following key studies associated with the evaluation of the
environmental impact have also been undertaken:
- Cooling Tower Study, evaluating the suitability of
recirculating seawater cooling towers in the Arabian Peninsula
coastal climate.
- Receiving Water Thermal Plume Study, evaluating the extent of
the thermal pollution of the discharged cooling water to the
receiving body of water.
