This paper presents and analyzes quantitative data on Interface Management in the oil and gas domain from a subsea contractor point of view. To develop subsea oil and gas fields four to seventeen contractors collaborate via Interface Management to ensure that the technical parts fit prior to implementation and integration. This research has both analyzed quantitative data from seven large projects, and investigated the topic in depth using interviews. The results prove that late involvement of contractors contribute to project cost growth during project execution. The detailed analysis of a reference project showed that almost one third of the contractor's contractual changes were due to supply gaps toward other contractors. Early implementation of Interface Management could help mitigating this, and ensure project execution within predicted cost and schedule parameters.
