Unplanned loss is reduced on the Norwegian continental shelf (NCS) through using Multifield Operations. Multifield Operations entail an overall responsibility for maintaining the integrity of certain equipment through condition and project based maintenance. Tasks, responsibility and professional resources are organized in one unit for multiple installations. This allows for synergies and a unique experience transfer and establishment of best practice. Engineers, executing personnel, planners, condition monitoring, and follow up is gathered in one unit.

Through monitoring, they detect negative trends and errors in an early phase and maintenance carried out with resources that hold operational expertise in the certain discipline in a project based model. Work is planned and implemented in close collaboration with the installations, operations groups, other internal specialist groups and vendors in a proactive, planned and controlled manner. They manage both planned and unplanned work on the systems and equipment in a standardized way.

Most of the pre- and post-operational work is done onshore. Planning is essential to managing resources and prioritizing between tasks based on HSE and production criticality. Quality assurance and risk management is integrated in the planning process.

The paper will address how Multifield Operations are managed through principles of collaboration technology and understanding human factors. The paper has been developed through field analyses. The Multifield Operations model has been applied to rotating machinery, fiscal metering, telecommunication as well as safety and automation systems on more than 29 installations. The model is of great use both to other operators as well as a multitude of related stakeholders and disciplines.

Multifield Operations contribute to a substantial reduction in unplanned production loss. The Multifield Operations model allows the company to plan approximately 1000 maintenance and improvement campaigns across 29 installations yearly, 80% as delivered on plan, with a serious incident frequency (SIF) of zero and they receive positive "client" feedback on their customer satisfaction survey. In addition they complete more work with less resources by gathering and using them across installations.

Multifield Operations may be the best sustainable option in a market where resources are getting scarcer and production moves deeper and colder by the year. It requires smarter and increasingly automated ways of operating. Multifield Operations contribution is a holistic approach to condition and project based maintenance.
