Hi All,

I am currently conducting a research on the oil and gas construction industry focusing on the study of the oil platform cost.

Much appreciate if anybody could share with me the rule of thumb in estimating the cost/tonne (a contractor's cost) for the following type of platforms:-
1) conventional fixed platforms;
2) compliant tower;
3) vertically moored tension leg and mini-tension leg platform;
4) Spar
5) Semi-submersibles
6) Floating production, storage, and offloading facility
7) sub-sea completion and tie-back to host facility.

Thanks
