Condition Assessment for Offshore Platforms Reuse
Gaugenrieder, S. (RINA Services S.p.A.) | Pellegrino, C. (RINA Services S.p.A.) | Copello, S. (RINA Services S.p.A.)
ABSTRACT Nowadays most of the Oil and Gas Companies, in view of a project for the exploitation of a new shallow water oilfield, are considering to reuse existing offshore structures removed from previous service site. This solution is considered strategic, in comparison to the construction of a new platform, with respect to the time required to production, which can be anticipated. Moreover the cost benefits may prove significant taking into account the lower price of the used platform compared to the cost to be incurred for the design/construction of a new structure. Cost saving is the issue but, of course, also the structural safety is to be considered as primary target: therefore, in view of the possible purchase of the existing structure, it must be carried out an appropriate assessment in order to confirm the engineering feasibility of the project and analyze the costs with the purpose to quantify the economic benefits. First, the feasibility study consists of evaluating, by means of a system structural analysis, the residual life of the platform in relation to the new installation site conditions (e.g. soil, waves, current, etc.), then the platform assessment shall include the execution of a gap analysis between the requirements of codes & standards, specifications, procedures used as reference for the original project and those defined by the potential purchaser in order to highlight any discrepancies. As a definitive step, a survey must be carried out according to the "condition assessment plan" prepared on the basis of the findings of the above mentioned activities. This plan is intended to describe the inspection activities by defining, for example, the non-destructive methods and extension, the laboratory mechanical and chemical tests to be carried out. In addition the "corrosion assessment" of the existing structure must be carried out during the survey. Based on the findings coming from the survey, additional checks and tests will be carried out; moreover, if necessary, a refurbishment, repair or modification plan is to be issued. In conclusion, the correct execution of the above described activities will provide to the potential purchaser greater confidence on the usability of the existing platform and all the elements needed to perform an accurate economic evaluation for his final decision making.

A Governance Approach Based On ISO 26000 for the Oil and Gas Industry
Severino, L. (RINA Services S.p.A.) | Turati, P. (Eni S.p.A.)
ABSTRACT The objective of this article is to give a practical guidance in order to promote ISO 26000 in oil and gas industry, with a high complexity of decision-making structures and with a high complexity of context. The international guidance on Social Responsibility ISO 26000 enables a holistic approach to different issues of sustainability, balancing the various needs of creation of business value, governance, economic and social development, energy saving, environmental protection and fight against climate change and is particularly useful for organisation which operate in complex circumstances. A governance approach based on ISO 26000 helps oil and gas industry in monitoring, measuring, managing and reporting the negative and positive impacts of its operations. The first step is to move on due diligence, taking into account the expectations and interests of relevant stakeholders and the context in which the organisation operates. In this way oil and gas practices can be reconciled with the needs of community, governments and clients. After the appropriate due diligence which takes into account all themes of Social Responsibility, performance gaps and opportunities for improvement can be defined. Oil and gas industry can set objectives and action plan to reduce these gaps, to adjust its operation processes or activities or to re-fix business. The level of implementation of ISO 26000 can be checked by a Third Party, which provides assurance on orientation towards the principles, Core Subjects and specific Issues of corporate Social Responsibility. The article includes a practical case study: presentation of Eni case. Eni has decided to implement a sustainability upstream management system based on ISO 26000 and has asked a Third Party to assess the level of implementation of this standard at different site/subsidiaries.
