A typical decommissioning project starts with studying the situation and applying for permits. The question of which method to use then soon arises.
Comparative analysis of decommissioning methods is easy to manage. A project team evaluates the advantages and disadvantages of piece-small decommissioning, reverse installation, single lift, or other removal methods. The results are then reported to the management briefing using attractive graphics for better visualization. Heavy lift contractors also present their inputs to generate these images and provide supporting evidence for the budget.
Other decommissioning methods (e.g., piece-small) are hard to budget in the initial project phases. Therefore, the heavy-lift contractors already have a head start.
Budgeting removal methods that do not depend on scarce marine assets is challenging. For accurate budgeting, those responsible must have much offshore experience. These field experts should be able to translate their experience into budgeting. The involved risks and opportunities have to be quantified to understand the conclusions. The type of experience of the field experts presents an additional challenge, which is often related to conservative techniques. In addition, their expertise is often related to a specific heavy lift contractor.
