CONCLUSION

CONCLUSION

Gas handling needs specialistic knowledge: thermodynamics

safety concepts /Rules ….

materials / metallurgy / special welding

technological limits

assembly

gas carriers design

Designer to give specialistic assistance to the Client: HAZID (design) / HAZOP (operative risks)

transfer / bunkering

gas freeing / gassing-up / cooling down
