Abstract: Offshore platforms are huge steel or concrete structures used worldwide for a variety of functions including oil exploration and production, navigation, ship loading and unloading and to support bridges and causeways. Construction of these platforms represents a significant challenge to designers, planners and environmentalists. The environmental challenge is how to construct these platforms as huge as possible to satisfy all required functions but with less possible environmental impacts. Environmentalists encourage using Environmental Management System (EMS) to ensure including of environment issues in the operation of companies/businesses which perform construction processes. Operations are maintained by Business Processes Management (BPM) and Business Processes Re-engineering (BPR). Efficiency of EMS depends on these two concepts; BPM and BPR. In construction, site wise Environmental impacts Value Management (EiVM) will lead to achieve planned environmental objectives. Environmental impacts of different types of structures can be assessed by using Life Cycle Assessment (LCA) method. The efficiency of the overall environmental management depends on the degree of compatibility between EMSs of project parties and the procedure by which the project activities will be environmentally managed. This study aims at analyzing the elements required to reinforce this compatibility. It suggests a theoretical framework for Project Environmental Management (PEM) based on EMS, BPM, BPR and EiVM. It is expected that this framework will effectively tie EMS to EiVM. Such conceptual frameworks will encourage more researches about value oriented EMS.
