Special cables for safety valves in oil pipelines

January 10th, 2012, Published in Articles: Vector

After the devastating oil disaster in the Gulf of Mexico, safety and environmental protection have become critical issues for the oil and gas industry. Lapp Muller SAS from Grimaud in Southern France, part of the Stuttgart-based Lapp Group, is particularly pleased about this. Because of their many years’ experience and excellent reputation, Lapp Müller recently won a contract from the Italian company Breda Energia for an international project in conjunction with GISMA and SEACON from the USA. The contract involves the development and production of an underwater cable (umbilical), made up of high-pressure hoses and control cables for safely opening and closing underwater valves in oil pipelines at a depth of up to 50 m off the Mediterranean coast of Egypt. The cable has been produced in a single length of 900 m. It has a tensile strength of nine tons and weighs a total of almost six tonnes. The control cables open and close the 56 inch valves using the high-pressure hoses. The cables are also connected to the controllers and drives, which control the position of the valves. The internal logistics alone brought major challenges for the employees, as the project had to be completed in less than three months. Before the underwater cable was approved and delivered to the customer, it was tested for safe functioning and reliability for a week by specialists from Seacon.
