Drilling and Well Related Services
NCA provides a wide range of specialised services for wells and wellheads, including cold cutting, machining, hot tapping and composite repairs. The services are based on fit for purpose, ATEX approved, equipment.
Cold work enables you to carry out the work on site without having to shut down the production. Most cold cutting methods are remote controlled and highly efficient compared to traditional torches and grinders, giving improved work environment for the workers and potential cost and time savings. When required, extreme accuracy and smooth cut surfaces can be achieved.
Based on our wide experience and wide range of methods available we will assist you in choosing the best method for your application.
