In a project, variations in weight during and after the design phase are an unwanted factor. To prevent this variation from occuring, weight estimates need to be as accurate as possible in the early stages of a project.
Software used for accurate estimates
Ramboll Oil & Gas’ software system WEPS (Weight and cost Estimating and Project Screening) is the tool to make these accurate estimates that can ultimately assist our customers in the crucial decision-making process of a project.
Reliable weight estimates serve as a basis for determining:
- Weight budget
- Concept feasibility study
- Project cost
- Project schedule
- Weight monitoring
Once the project is being developed weights must be reported at regular intervals to ensure correspondence between weight estimates – and budget- and weight take offs (WTO). This reporting ensures that any variations are identified and properly evaluated. Differences between weight budget and the weights reported by each discipline constitute the weight contingency.
