Salvaging and Reusing Jacket and Deck Structures of Offshore Platforms

Abstract

Reusing salvaged offshore oil and gas production jacket and/or deck structures is a means of reducing the construction cost and schedule. The decision to salvage, refurbish, and reinstall an unused jacket and/or deck structure(s) can benefit oil companies in two ways. First, the platform must be removed to meet environmental regulations; second, the platform's jacket and deck can be reused on future projects, resulting in construction-cost and schedule savings. The primary objective of this paper is to present a framework within which decision makers can identify a salvage process and reuse a platform when it is no longer in production. The second objective is to document the cost and schedule savings obtained when the platform's jacket and deck are reused. The data presented in this paper can be used by oil and gas companies to determine whether the reuse of a salvaged structure is a cost-effective alternative to building a new structure.
