MACHINING
TOP EXPERTISE, EXTENSIVE EQUIPMENT: Our machining department consists of highly skilled CNC operators within reparation, maintenance and newproduction of equipment for the oil and gas production. NWGs production management has an extensive pool of machinery, which contributes to the right quality, effective solutions and solid execution capabilities.
We specialise in time critical projects and have one of the highest capacities for repairs of well and drilling equipment among machining workshops in northern Europe.


WELDING
EXTENSIVE EXPERIENCE, FIRST CLASS EQUIPMENT: All of our welders have considerable experience of the weld cladding and stub welding of well and drilling equipment for offshore-related industries. We have approved welding procedures for various types of materials for a number of major players in the Norwegian petroleum industry, and we use Inconel cladding procedures for the most commonly used AISI materials. We have three CNC-controlled, completely automated TIG cladding units, heat-treatment equipment and furnaces.
MECHANICAL-ENGINEERING
When equipment fails, costs mount up quickly. NorthWellGefro offers rapid response and fast delivery of repairs and maintenance of mechanical equipment. Our expert technicians understand the importance of working hard to minimise expensive downtime. This ensures that our customers’ wealth-creating operations come back on line quickly, and also reduces their costs from keeping spare parts in stock. This is why North Well Gefro is recognised as a leading mechanical-engineering plant.

LOGISTICS
OPTIMUM RESOURCE UTILISATION: Logistics is all about service, quality and optimal utilisation of resources. NWG makes every effort to get as much as possible done as quickly as possible, in order to reduce internal and external lead times. This enables us to meet the customers’ needs for a rapid and secure delivery.
Our stringent requirements with regard to correct and efficient time utilisation come into play right from the first customer contact, and apply throughout the entire transport, production and installation chain until the product is completed. We have efficient systems in place, which save time in the exchanges between the various working operations, where we map the flow between the various links in the chain and ensure the necessary follow-up in terms of certification and documentation. We have set up an integrated and simplified system, which accelerates the flow of goods in the company and ensures a steady workflow, quality and flexibility throughout the process. We also place great importance on reliability of delivery, and pay close attention to important details such as the quality of the packaging right up to the point of delivery.
NWG always strives for continuous communication, precise information and qualitative documentation during all steps and phases of the project.
Our top modern machines are fully equipped for all types of work, and ensures that we are very flexible, versatile and open to all types of assignments. The Schiess we have in our workshop is one of few in Norway that can process parts up to 15 meters. And with 48,000 budgeted hours of work in 2015, you can be assured that the job gets done, and that we have the crew as needed at any time.
