Low oil prices leads to a need for large cost reductions and improved effectiveness in the subsea oil and gas industry. At the same time, production in harsher environment and deeper water is inducing a need for more complex production systems. Increasing complexity reduces the tolerances for successful manufacturing and installation. Increasing robustness of the installation process can reduce installation costs. Robustness of the installation process is dependent on successful tolerance management. This paper investigates different methods for tolerance management. The conclusion is that successful tolerance management partly is independent on the chosen method for tolerance analysis. The research shows that successful tolerance management relies on understanding of the tolerance chain, cooperation, and early initiation. We applied system modelling as a system engineering approach to support manually calculated tolerance budgets. The research finds that this supports understanding, exploration, and communication. We recommend this as best practice. The research shows that tolerance management can contribute to increased robustness of the installation process by including manufacturing and operational factors in the tolerance analysis. System modelling and budgeting support discussion and exploration of these factors.
