New technologies and HSE approach
In the design
During construction
For operators
15
New approaches in the design
Intensive use of electronic mailing to allow « real time » coordination betweenpartners and with fieldEDMS for document circulationFull ISO 9000 complianceDynamic simulation for earthquakecalculationElectronic 3D model
16
New approaches in the design (foll’d)
Dampeners to absorb dynamic loads from waterhammer in unloading linesIntegrated control & command systemFiber optic cablesErgonomic study of the control room andoperators offices interfaces
Better communicationFaster response in case of alarm or emergencyCorrect lighting to avoid useless constrains
Wireless telephonic system

TGE seismic approachearthquake levels
As per EN 1473 definitionsOBE = operation basic earthquake
Plant must remain operational after earthquakeNon-essential components could be damaged provided it will not affect the plant safe operation
SSE = safe shutdown earthquakeDesign as per classificationOperation resume could require important repairsNeed to keep monitoring of important tank and process data
22
Seismicity
Area in seismic area0.15 g acceleration for OBE0.5 g acceleration for SSE
Acceleration value at the ground levelNeed to develop a global approach to
guarantee integrity and stability of systems and structure but without over-design
23
TGE seismic approach as per EN 1473classification
4 classes on a safety point of view:Class A: vital for safetyClass B: failure could bring an additional hazardClass C: could not collapse as collapse could affect A or B classified itemsClass D: other items for which no specific requirements
Other considerations (operating costs or capital losses): to be discussed with client

TGE seismic approachbasic principle
Plant will be shutdown after any earthquake
