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
