Large losses are typically the result of the failure of multiple safety barriers, often within complex scenarios. An innovative methodology accompanied by a dedicated software baseline risk assessment tool (BART) has been set up to cover all types of onshore and offshore installations and to allow any exploration and production organization to monitor all of its assets' status with a common and standardized approach. The BART tool combines a simplified quantitative risk assessment methodology with a bow-tie model approach to identify and assess potential hazards and associated risks, that may arise from a process or activity carried out in an upstream onshore/offshore installation. The event sequence of any major incident is analyzed from the identification of primary root causes up to the determination of potential effects and associated impacts. Therefore, all existent safety barriers are identified and their prevention and mitigation risk reduction contributions are included in the analysis. The BART tool allows for a systematic monitoring of all major incident risks through the selection of effective control measures able to reduce the likelihood and/or to limit the potential effects of current risks. The BART methodology has been tested on some existing onshore and offshore oil and gas installations, and the main findings have been positively compared with alternative approaches. © 2011 American Institute of Chemical Engineers (AIChE).

This paper presents the results of a two years project led and funded by Eni from 2008 to 2010 with the aim of supporting the development and experimentation of innovative technology for environmental monitoring. The problem addressed is the precise estimate of possible altimetric variations of the seabed through long-term monitoring. The selected methodology consists in the application of repeat-track interferometry to high-resolution, high-frequency sonar data collected from an AUV during repeated surveys of a seafloor area of interest. The paper describes the experimental measurements conducted at sea, the SAS and interferometry methodologies developed, and the results obtained on artificial objects sitting on the seabed. The quality of the achieved focusing is analyzed. The achieved repeat-pass SAS interferograms are shown and analyzed. The coherence along time of the particular kind of seabed (silty sand) characterizing the experimental area is presented and the utility of artificial reflectors for long-term SAS interferometry is discussed. © 2011 IEEE.

A novel approach to nonlinear finite-element analysis of concrete structures exposed to fire is presented. The proposed formulation refers to frame systems, but it can be extended to other types of structures. The main novelty of this formulation is the use of a special class of evolutionary algorithms, known as cellular automata, to describe the heat transfer process induced by fire and to create an effective link between the simulation of the thermal process and the structural analysis. The heat transfer process is reproduced by considering heat conduction, heat convection, and thermal radiation. The temperature effects on the structural performance are taken into account by means of temperature-dependent thermal and mechanical properties of concrete and steel. In this way, the general criteria for nonlinear finite-element analysis of concrete structures are applied to formulate a cellular reinforced concrete beam element with temperature-dependent characteristics. The effectiveness and applicability in engineering practice of the proposed formulation is demonstrated through applications. The results prove the accuracy of the proposed procedure and show that, for statically indeterminate structures, fire safety needs to be evaluated at the global level by taking into account the actual role played by the structural scheme. © 2011 American Society of Civil Engineers.

The integrated study, concerning the experimental observations, was performed during the oceanographic cruises on-board the two NURC research vessels, in the period between 2008 and 2010 in the Marine Protected Area of Cinque Terre (North-West Mediterranean Sea, Italy). The aim of the research is to describe the environmental features using both hydrological parameters and AUV navigation tracks, acquired respectively by a multi-parametric platform (MEDUSA) and AUV MUSCLE. The innovative contribution of this work is the possibility to evaluate the bottom stream without direct current measurements, but using the navigation data recorded by AUV. This work is a complementary analysis to environmental support of the ENI S.p.A. Exploration and Production Division project. ©2010 IEEE. Source

An innovative methodology accompanied by a dedicated software BART (BAseline Risk assessment Tool) has been set up to cover all types of onshore and offshore installations, and to allow any E&P organization to monitor all its asset status with a common and standardized approach.
