Environmental Resource

Brazil has performed an important role in the oil and gas industry mainly because the offshore E&P activities in Campos Basin, characterized by deep waters far away from the coast and its sensitive areas. However other basins have increased their importance in the E&P industry where some operations are located very close to the shore in shallow waters with a remarkable environmental sensitivity. Because of this, a new approach has been adopted by Brazilian Federal Environmental Agency (IBAMA) - firstly regarding oil spill preparedness and lately concerning environmental risk assessment. Risk analysis used to be developed as a preliminary hazard analysis (PHA) part of the environmental impact statement that operators (oil companies) have to perform in order to obtain a permit to operate. The main feature of this PHA was the qualitative and subjective risk assessment taking into account only the oil spill amount, in spite of the area sensitivity. Once the operations in those high sensitivity areas have potentially increased, IBAMA has developed a particular Term of Reference regarding the oil spill risk calculation for valued environmental resources such as marine mammals, sea turtles, fishes, etc as well as ecosystems (for example, coral reefs and mangroves). According to the new approach the environmental risk assessment regards to the recovery time of any valued environmental resource that could be affected by oil spill in comparison with the leakage occurrence time. The oil spill risk related to a valued environmental resource is calculated by the product of the release frequency and the environmental consequences based on exposure probability. This paper discusses this new approach adopted in Brazil, involving a quantitative method for the environmental risk assessment of Brazilian Offshore E&P.

The Impact

Environmental risk assessment is becoming an increasingly important factor in the assessment process for new projects. The oil and gas industry is familiar with assessing and managing risks from a wide range of sources. In particular, risk assessment and management is fundamental to the evaluation and implementation of Safety cases. Risk assessment is essential in valuing exploration acreage. Various industry and government risk management standards and criteria have been developed for public and occupational health and safety.This paper examines the extension of these approaches to environmental risk management for the offshore oil and gas industry and proposes a conceptual management scheme.We regard risk as the probability of an event occurring and the consequences of that event. The risk is classified into four categories, namely:primary risk, which relates to the mechanical oilfield equipment;secondary risk, which relates to the natural transport processes. For example dispersion of oil in the water column and surrounding sea;the tertiary risk, which relates to the impact on some defined part of the physical, biological or social environment; andthe quaternary risk, which relates to the recovery of the environment from any impact.Generally the methods of quantitatively analysing primary and secondary risks are well known, while there remains considerable uncertainty surrounding the tertiary and quaternary risk and they are at best qualitative only. An example of the method is applied to coral reef and other sensitive areas which may be at risk from oil spills.This risk management scheme should assist both operators and regulators in considering complex environmental problems which have an inherent uncertainty. It also proves a systematic approach on which sound environmental decisions can be taken and further research and analysis based. Perceived risk is recognised, but the management of this particular issue is not dealt with.

Oil Spill Response

Following key oil spill incidents in the Gulf of Mexico and Australia, the industry initiated a three-year Joint Industry Project to develop guidelines for oil spill preparedness and response management. These documents are commonly known as the Oil Spill Response JIP (OSR-JIP) Good Practice Guides. As the OSR-JIP originated from lessons learnt from offshore incidents, it is only natural that the industry would apply it with the same type of operation, hence the tendency to limit the practical application for inland or near-shore facilities. This paper presents two examples where the OSR-JIP guides are applied at downstream operations located inland and near-shore. The first study is on a refinery located near-shore with an operational jetty and a single buoy mooring. We started with a comprehensive review of their operations and updated their oil spill risk assessment profile in line with the framework described in the OSR-JIP Tiered Preparedness and Response. This process provided a reflection of their current capability and identified the gaps for further improvement. Following this, we proceeded to update the contingency plan using the OSR-JIP Contingency Planning to ensure that the risks identified are adequately mitigated with training of personnel and equipment selection. This exercise supported in improving the readiness of the facility to respond to oil spill incidents in future. The second study involves a terminal located inland that supplies refined products through a pipeline that leads towards a jetty on the coast. We developed several area specific tactical response plans that cover risks from their above-ground pipelines and at the jetty where loading and offloading of the products to tankers are conducted. To accurately define the suitable response technique, we started the planning process with an oil spill risk assessment following OSR-JIP Risk Assessment. The tactical response plans were then developed with reference to several other OSR-JIP guides such as OSR-JIP Inland Response and NEBA. The resulting plans describe health and safety concerns, identification of sensitive receptors, response techniques, location and quantity of resources, logistical requirements and timings and waste management. Based on these case studies, we demonstrated that the OSR-JIP guides can certainly be applied for inland and near-shore facilities and have a more far wider application for the whole oil and gas industry rather than be limited to offshore operations.

ABSTRACT It has been pointed out that one of the pitfalls associated with using a combination of computerised oil spill planning tools is the general lack of integration between the different sub-tasks. Det Norske Veritas (DNV) has been developing and using the EMDROPS tool for Environmental Risk Analysis, Response Analysis, and Contingency Planning. EMDROPS employs the MIRA method for Environmental Risk Assessment (ERA), adopted by OLF, the Norwegian Oil Industry Association, thus the results from the ERA can be put directly into the Response Analysis/Response Planning, using the same oil spill and environmental data as used for the ERA. EMDROPS is integrated into a standard GIS (ArcView) which allows the different modules (Oil Spill Modelling, Vulnerable Resources, Environmental Risk Assessment, and Response Planning) to be used in a seamless manner. Some of the data available to the user is the Norwegian Marine Resources Database (MRDB) and an oil spill equipment database which is used by the Environmental Risk Analysis and response effectiveness analysis.

ABSTRACT How can a process be flexible enough for use in any incident, yet rigid enough to provide the structure required in times where stress is high, and time is short? In 2014 the IPIECA-IOGP Joint Industry Project (JIP; an outcome of the 2010 Gulf of Mexico oil spill) recommended the implementation of a structured Incident Management System (IMS) in their publication of a Good Practice Guide (GPG): Incident Management System for the Oil and Gas Industry. Now, half a decade on from this publication, many oil companies have, or are in the process of implementing some form of IMS across their global operations. The GPG describes IMS as a “set of proven organizational and management principles.” It also states that it is based on ICS as it “is a version of IMS that is widely used by Industry”. As multiple IMS's exist globally, this paper explores whether the blanket adoption of a single existing system can be used when so many considerations, are required. Through observing and assisting their members in introducing (and maintaining) an IMS across various business units, Oil Spill Response Limited (OSRL) has seen how systems can be tailored that are flexible enough to meet the specific needs of the company concerned. Examples include introducing initial assessment procedures and customisation of documentation. Potential limitations of ICS possible evolutions of IMS are discussed. Incorporation of the organisational and management principles described by the JIP provides guidance when modifying/tailoring a system that can be used by businesses facing different scenarios in different environments and with differing levels of resources. The change in terminology from the Incident Command System to the Incident Management System allows for customisation of a proven system and increased flexibility whilst being based on tried and trusted foundations.
