Engineering Phase:
Basic Engineering review and coordination, adapting international EPC engineering practices to local engineering ones, in particular on normative and scope.
Full Definition and DCS – SCS software development
Solar Field
Supply of Engineering and procedures. Supply of Jigs for Solar Field collector component Manufacture and Assembly, introducing new concepts from other designs that allow a higher assembly capability and easy traceability.
By continuous QC / QA of the assembly process, up to each individual SCE, it was possible to identify when to carry out realignment of Jigs.
Accurate initial balancing position definition, leading to fast reach of Solar Field outlet temperatures close to nominal.
Solar Field logic improvement was helped by onsite engineering knowledge, as to troubleshoot on-the-go and analyse performance since initial focusing of SCAs.
HTF System
Operation of HTF systems on DCS during initial start-up of equipment and systems and on critical first-time operations
Steamblowing definition and supervision by Ingenergio, coupled with SGS Engineering coordination, were key to optimizing the partial HTF filling while allowing the remaining SF commission to take place.
Very high degree of Construction completion avoided halting commissioning activities due to lack of system finishing.
High degree of piping cleanliness, both in SF headers and Power Block piping, resulted in no need for HTF pumps filter cleaning and unperceivable HTF boiling process.
HTF sequential filling together with the afore mentioned cleanliness and fast HTF unloading, helped optimize the commissioning schedule, by eliminating the requirement of full plant HTF filling which is usually restrained by the HTF logistics.
BOP System
Overall coordination of commission activities on the water/steam cycle and auxiliaries
Steam blow definition (Engineering): circuits, blow conditions, temporary tanks and piping, water programme… Blow supervision and target validation onsite.
Definition of chemical control criteria during commissioning: dosing targets, sampling requirements, validation of on-line analysers, troubleshooting on excursions of iron, conductivity, silica…
Overall coordination on transition from blows to turbine loading restoration, first steam, steam quality obtention, ST tests, plant operation during loading. Troubleshooting support for ST start-up limiters.
TES System
Coordination of Molten Salt Tank Engineering, including:
Mechanical tank design
foundations design
instrumentation definition
design review and validation of main equipment:
Salt-HTF heat exchangers
Salt pumps
Electrical heat tracing
Electrical tank heaters
Detailed design of valves (HTF, salts, safety, and breather valves) and tank insulation
Introduction of new suppliers to CSP application, leading to thorough review of equipment materials and functionality.
Definition and validation of tank preheating equipment. Supervision of the preheating process
Design of a high-capacity salts melting system, from conceptual to detailed equipment development.
