Bauer puts across ingenious solutions

The company has maintained the flexibility to produce the nitrogen, which reduces operational risks and result in greater cost savings for operators

The use of nitrogen in the offshore oil and gas industry has decades-long history, and continues to play an integral role in the day-to-day operations aboard mobile offshore drilling units, FPSO’s, and drill ships around the world.

Many applications, such as the blanketing or inerting of storage tanks aboard FPSOs, or the charging of subsea blowout preventer (BOP) accumulators, revolve around safety; others, like the drying of coiled tubing to prevent corrosion resulting from long-term moisture exposure, serve largely economic concerns, says a spokesperson for Bauer Kompressoren.

Without nitrogen, completing these tasks would come at increased operational risk and result in greater costs for operators, she says.

Bauer has come up with a solution to meet the requirements of ‘Onsite Nitrogen Generation’.

"We have maintained the flexibility to produce the nitrogen. For example if a customer has low pressure air source available on site, we would supply skid for the membranes and booster with optional nitrogen storage tank with 5000 psi storage pressure, 98 per cent purity," she says.

In case low pressure pure air is not available on site, Bauer’s complete integrated solution will be the best option even in offshore conditions. Some distinctive features Bauer offers on SNG II are user-friendly Interactive touch-screen interface pre-programmed maintenance alerts, ROI approximately 2 years and even less for extensive uses and continuous availability of gas at high pressure.

For some applications, like blanketing or inerting, nitrogen is required at low pressure of 2 bar. For such requirements, Bauer’s modular option NGM will be a best fit, she adds.
