I am workin in a small project organisation .We are presently engineering a small oil and gas separation project.

at the beginning of the project, the client in fast start of the project verbally agreed to the proposal by our stress engineer that friction shall be considered at resting supports and friction at guides and line stops shall not be considered as it is not necessary.

Almost 80% of the engineering is over, client has now appointed a consultant who has instructed us to also include friction at line stops and guides.

our organistaion has strongly objected to this instruction saying that the consultant has looked at the situation from a very conservative and academic point of view . and this will affect our pipe routing due to revised nozzle loads.. Even the loads provided to civil could change and the site contrator shall penalise us since he has already procured and fabricated strutural steel sections as per our calculations.

the client consultant has put his foot down. There is now a stalemate.

can anybody please explain to me how there can be friction at line stops and anchors and which of the two above organisation is correct in their requirement.

awaiting your reply,

regards,
alexsel
