Offshore Environmental Monitoring can be defined as technical and institutional activity aimed at measuring, evaluating and tracking potential physical, chemical and biological environmental changes which could be induced by operative activities or by external causes.
By carrying out this activity, the oil company can take the appropriate corrective measures for creating a Monitoring Plan related to the offshore e&p projects and operations.
According to this approach, the baseline information on pristine conditions is compared against exploration drilling, development and post-development impacts. Efficiency of mitigation and restoration measures can be assessed through the monitoring activity.
Since early ‘90s, eni has carried out several environmental monitoring campaigns around its offshore installations worldwide aiming at evaluating changes in the current state of the interested area and in order to assessing evolutionary trends of environment. These surveys were able to provide early warning of any potentially serious impact and to provide data for strategic decisions. Besides they have been supporting to determine whether any detected change in physical, chemical and biological components was caused either by e&p activities or by natural occurrences.
Based on the above considerations, this paper introduces guidelines on strategy approach carried out by eni in offshore environmental monitoring, during the project life-cycle.
