Facilium's LoFS Cost Calculator provide our Clients an initial idea of Capital Expenditure and Operating Cost for a LoFS system in virtually any type of feasible installation and operating condition

Background

Facilium has participated in leading roles in a number of LoFS projects, from the early Appraise phases and through system installation and operation. Through these we have gained exclusive experience of estimate costs compared  to actual cost. There has been a learning curve, as we have participated from the very first commercial installations and many of the realized and non-realized projects since then. All projects have risk elements for cost of system establishment and realization. Facilium has analyzed many of the perceived risks in the early stages and experienced mitigation of and resolution of actual risk through the project development.

Our method of calculation follow these general principles. We use the best experience available for supply, installation and operating costs and quantities. Based on that we create Norm, Low and High budget estimates, and then based on the particular risk situation a Monte Carlo simulation which provide P10, P50 and P90 cost estimates. We have performed many such calculations for different fields, in different conditions.

Based on this experience, we have built a very complex LoFS database, with over 100 variables. A web based cost estimate calculator can practically only be built around ca 10 variables. So how is it possible to get accurate cost information? Our answer to this dilemma is as follows. We have simulated a great number of cases based on each of the 8 variables given in the LoFS Cost Calculator, and performed polynomial regression to the fourth order. This has provided an approximation to the data of 99% or better, or well within the tolerance factor of a pre-appraise budget, as long as the variable values stay within the Max / Min range given in the LoFS Cost Calculator.

Your security and privacy

The data you put into the calculator will not be display or registered to, or in any other way be made available, to anyone other than the logged in user. All calculation data or input information will only be available on screen and if so wished on the users printer.  NO DATA IS OR WILL BE REGISTERED OR STORED IN ANY FORM. The calculator will automatically be reset to default values when your session ends.

How to use the Calculator

The following 10 fields are available for input of variables:

  1. Case description (which will be shown above the data graph and table in order to segregate various cases)
  2. Units (Metric or US Customary Units) [Selection]
  3. Geographical area [Selection]
  4. Assumed Soil Hardness (Soft, Sand, Hard) [Selection]
  5. Average Water Depth (of the LoFS system) [Input]
  6. Reservoir area (= LoFS seabed area) [Input]
  7. Receiver line spacing (the distance between the sensor lines (X-line)) [Input]
  8. Receiver in-line spacing (Distance between sensor modules along the lines) [Input]
  9. Number of surveys over a period of 20 years [Input]
  10. Shot rim distance (the average distance from the circumference of the LoFS system to the extent of the seismic survey area circumference)  [Input]

The graph and cost estimate tables are continuously updated as data is selected / typed in to the fields. The graphs and the estimate cost tables can be viewed on the screen and / or printed
