Wood Group has successfully delivered topside modifications for Statoil’s Gullfaks Rimfaksdalen subsea tie-back project in the Norwegian North Sea, three months ahead of schedule and with significant cost savings.
Wood Group provided all engineering and project management including procurement, prefabrication and the planning and installation of offshore work packages under a contract awarded in January 2015.
Statoil and Wood Group’s team in Norway agreed to take an innovative approach to simplify the scope of the project, optimise the schedule and resources, with the overall aim to reduce cost. An important part of this work was to simplify the execution model without increasing project risk ensuring a vigilant focus on HSE.
Harald Anvik, project manager, explains: “From the beginning, the Wood Group and Statoil project teams worked together on a lean, structured approach which looked at efficient processes for engineering, construction, procurement and offshore activity. We examined each stage of the project delivery to streamline decision-making and address potential waste reduction.
“It was this planned approach to identify areas for improvement, supported by management, which gave such fantastic results demonstrating what is possible when a client and service company are fully aligned.”
A number of initiatives were undertaken to increase output and reduce man hours including improved engineering processes, scope optimisation and introducing alternative suppliers. Together with Statoil we found off the shelf, industry standard, solutions with simplified documentation.
Harald continues: “By stringently planning offshore work packages and installation, undertaking alternative work when available and multi-skilling our employees, we made optimal use of time and resources.
“Implementing a robust improvement plan meant we were able to reduce hours, associated costs and simplify our processes ensuring our focus remained on safety and quality. As a result, Statoil could start production from the field three months earlier than scheduled.”
Wood Group has worked with Statoil globally for more than 20 years and in May 2016, secured a Master Services Agreement to support the life cycles of its offshore and onshore facilities in the eastern hemisphere. Recent work also includes subsea contracts, support for the Statoil Technical Efficiency Programme and providing maintenance and modification services to four installations (including Snorre A, Snorre B, Visund and Grane) on the Norwegian Continental Shelf.
In Brazil, Wood Group provides operations and maintenance for two wellhead platforms, and modification services for the Peregrino Floating Production Storage and Offloading facility.
