  • Magma and Victrex cooperate on pipe subsea intervention line
  • Pipe be deployed to depths of 10,000 feet (3,000 metres), pressures of up to 15ksi
  • Application: extreme subsea Oil & Gas operations

To reduce exploration and production costs and risks in subsea oil and gas systems, Magma Global Limited has developed the flexible so-called m-pipe technology. Their latest lightweight continuous pipe is both the largest and longest Victrex PEEK-based structure ever. It can be deployed to depths of 10,000 feet (3,000 metres) and handle pressures of up to 15ksi (kilopounds per square inch). The composite pipe combines PEEK, high-grade carbon fibre and S-2 glass fibres to form a reliable subsea intervention line that meets the demand for a hydraulic pumping system that can handle high pressures and high flow rates.

Deployment package features vessel back-deck system with modular reeler

Magma is offering its m-pipe and integrated deployment package as a vessel back-deck system for rapid hydraulic light well intervention. The deployment system has a modular reeler with m-pipe intervention line pipe handling system, built-in tensioner, level wind, controls cabin, hydraulic power unit, installation platform and winch. The m-pipe is a composite material based on Victrex PEEK polymer, carbon and glass fibres that features low fatigue and high resistance to corrosion compared to steel pipe.

Features of the m-pipe technology

The m-pipe is lightweight for ease of installation and reduced pipe stress and features smooth PEEK bore for efficient and rapid flow of intervention fluids. In addition, it is resistant to well completion and stimulation fluids and gases.

The m-pipe and deployment system offers low-cost hydraulic well intervention, and can be rented as a complete deployment package from Magma. According to the company, the system is designed to minimise mobilisation time and maximise vessel utilisation by reducing hydraulic pumping time, reducing intervention costs by up to 30%.
