where E k is the Free Onboard equipment cost of equipment k in carbon steel, f alloy is the alloy factor for equipment, k, F L&M,k is the labour and materials cost for installation of equipment k and includes all ancillary materials such as piping, structure, electrical, foundations etc. C BL-L&M is the ISBL cost of installed equipment, C T F I is the cost for tax, freight and insurrance, C BL-P M is the ISBL physical module cost. C of f sites is the cost of offsites + indirects for home office and field expenses incl. engineering and project management. C BM is the bare module cost, adding contractors' fee C CF , contingencies for delays C C1 and contingencies for scope changes C C2 , the total module cost is found. Provided that the OSBL cost for cooling and heating will be accounted for in OPEX, the simplification of equalling the total module cost with the total plant cost is made. The applied factors are summarised in Table .
