Abstract: Considerable amount of Oil and Gas (O&G) production and process installations operating in the North Sea are getting aged and requiring continuous modifications. Nature of such contractual jobs is relatively short term with demanding deliverables. Hence, the engineering contractors require excellent coordination and seamless communication during all phases of a project. For any contractor/supplier, it is of utmost importance to ensure that equipment related technical information is made available at the right time to avoid any unexpected project delays. Experience shows that poor coordination among project participants can result in failing to comply with regulatory and governing requirements. Also, there are other challenges to managing tags, databases and tag history as well as keeping technical information integrity. This manuscript illustrates role of a tag management system developed by an engineering contractor company which provides services to operators in NCS. The particular system is developed and customized to meet a drilling rig client's specification
