"Maintenance is a combination of all the technical, administrative and managerial actions during the life cycle of an item intended to keep it in or restore it to a state which it can perform the required function". Nowadays, maintenance is acknowledged as a major contributor to the operational and fiscal performance of asset-intensive organizations; especially Oil and Gas organizations. Therefore, the management of maintenance departments strives to explore every opportunity to improve the performance and profitability of their departments and achieve cost savings for their organizations. Computerized maintenance management systems (CMMS) has rapidly evolved to become the central component in maintenance departments of many organizations. The rationale is simple, CMMS provides organizations with ample opportunities to optimize their maintenance and boost the reliability of their physical assets. However, realizing these opportunities is a daunting task. This paper describes a maintenance management framework for optimizing the maintenance of gas facilities using CMMS (SAP R/3 in the author's organization). This framework is a result of the positive evolution of the collaborative thinking of the maintenance department at the author organization's down-stream operations. This framework addresses and integrates the areas where CMMS can contribute the most to the organization's performance in terms of maintenance improvement and retum-on-investment (ROI). These areas are: Asset information management, work order management, resources utilization, performance management, fault analysis, capital equipment life plans and replacement decisions. The findings of this paper show that a holistic maintenance management framework is required for organizations aspiring to optimize their maintenance and maximize the returns on their CMMS. Without a working framework, they risk missing many of the benefits of CMMS and rendering the later a merely administrative tool. Copyright 2014, International Petroleum Technology Conference.

The main objective of an asset integrity management system (AIMS) is to ensure that the physical assets of facilities and pipeline system are operated in a reliable, efficient, and safe manner. Such motives can include the fitness to function safely and reliably; consistency with all industry requirements and international standards; compliance with company's AIMS philosophy, operating and maintenance philosophy and engineering standards/specifications as well as industry regulations. The AIMS goals shall demonstrate the persona of the company with an inward look into the company's values and shall be subjected to evolution rather than revision. At Dolphin Energy Limited (DEL), the QHSE philosophy of zero injuries, zero accidents, zero releases and no (minimal potential negative) impact to the public, the surrounding environment, and customers (zero leak thresholds) was supported by DEL's implementation of the most appropriate technology available. This review paper will demonstrate DEL's focus on proactively understanding the type, extent, and the effect of all potential defects and by implementing the best practices in the industry. Source

Dolphin Energy Limited (DEL) is considering reducing the native greenhouse gases (GHG) emissions from its Ras Laffan plant in Qatar. One important source of native CO2 is the gaseous effluents from the two sulfur recovery units (SRU). Dolphin studied the possible options for recovering up to 50 MMSCFD CO2 from the subject SRU's effluents upstream the thermal incinerator section in the SRU using existing infrastructures in its Ras Laffan plant. The recovered CO2 would be exported at medium pressure (MP, 7 bara) and/or high pressure (HP, 190 bara) to other users. The study investigated the possible options to recover and compress the CO2 product. Capital costs, utilities requirements, operating costs, carbon intensity savings, layout and electrical power supply were all studied. The study investigated the following technologies, which are based on amine solvents. (1) HP scheme with some feed gas compression to improve the performance of the solvent and reduce equipment size. (2) LP scheme with low pressure efficient technology that does not need much feed compression. (3) Revision of existing treatment scheme in the sulfur recovery unit to perform acid gas enrichment, tail gas treatment and CO2 capture with minimum modifications. (Copyright 2014 IPTC). Source

Dolphin Energy Limited's (DEL) production scheme is based on a wet transport of well effluents from offshore platforms to the onshore treatment plant. At the onshore receiving facilities, produced sour water is routed to water treatment units. Since the plant startup in 2006, non-chemically contaminated waste water is used for irrigation after treatment. Produced waste water and chemically contaminated waste water are re-injected into a deep reservoir without any major treatment further to H2S stripping, oil skimming, pH control and multi-media filtration. However, local authorities have expressed their concerns about the quality of water injected and the potential risk of long-term injectivity loss. As sealines need to be protected against corrosion using a corrosion inhibitor (CI) and hydrate formation by using kinetic hydrate inhibitor (KHI), produced water recovered onshore is chemically contaminated with polymer based chemicals. As KHI could damage the reservoir, it has to be removed from produced water prior to reinjection. Dolphin Energy launched bench scale tests with a third-party laboratory to identify the best treatment scheme to remove KHI. Source
