Rolls-Royce wins order to power new European gas pipeline

Friday, 16 February 2007

Rolls-Royce has won an order from MEDGAZ for three of its latest technology RB211 gas turbine packages to power a new Mediterranean sub-sea pipeline to transport natural gas from Algeria to Spain.

The gas line, scheduled for completion in 2009, will carry gas for 210 kilometres on the seabed from the coastal city of Beni Saf in Algeria to the Spanish province of Almeria.

The three 44,000 horsepower RB211-6761 DLE (Dry Low Emissions) units will be installed at the Beni Saf terminal to provide the front-end gas boosting required for the underwater pipeline, which will reach a maximum water depth of over 2,160 metres. The pipeline will provide eight billion cubic metres of natural gas per year directly to the European market.

Tom Curley, President of the Rolls-Royce energy business, said: “We are delighted to receive this order for RB211-powered packages.

“We have already supplied seven RB211 units to Europe Maghreb Pipelines Limited to power another sub-sea gas pipeline (GME pipeline) from Algeria to Spain, via Morocco, and these have been operating since 1996. Now, we are very pleased to be chosen to supply equipment to power the next Algeria to Spain pipeline project.”

Spain’s Ministry of Industry, Tourism and Trade awarded MEDGAZ priority ‘A’ status in 2005 as it regards the new pipeline essential for Spain’s energy infrastructure. It has also been included in the list of ‘Projects of common interest’ within Trans-European Energy Networks (TEN), making it an international project.

The MEDGAZ contract is the latest for the RB211-6761 DLE, a gas turbine with significantly more power and better fuel efficiency than previous versions.

The RB211-6761 DLE also provides an exceptional reduction of exhaust emissions – 82 per cent fewer nitrous oxide (NOx) emissions compared to units installed on some earlier natural gas pipelines.

As the most cost-effective, efficient and environmentally-friendly way of delivering natural gas to Southern Europe, the sub-sea link will help meet the goals and targets set out in the Kyoto Protocol.

With an overall efficiency in excess of 40 per cent, the RB211 is well suited for natural gas compressor stations like this one at Beni Saf that squeeze natural gas to many times the atmospheric pressure to drive it through pipelines connecting gas reserves to the marketplace.

The three gas compressor packages will be manufactured at the Rolls-Royce facility at Liverpool, UK, for delivery to the Beni Saf site in the 4th quarter of 2007 and the 1st quarter of 2008.

  1. The RB211-6761 gas turbine units will each power high efficiency DATUM barrel gas compressors supplied by Dresser-Rand.
  2. The seven RB211 gas compressor sets on the Europe Maghreb gas pipeline are installed at two compressor stations along a line that exits North Africa near Tangier before it goes under the Straits of Gibraltar and into Spain on the outskirts of Tarifa.
  3. Over 670 Rolls-Royce gas compression sets have now been ordered or delivered for 45 pipelines in 24 countries.
  4. Rolls-Royce RB211 industrial gas turbines have over 20 million hours of operating experience worldwide.
  5. Rolls-Royce industrial gas turbines, including two RB211 units, have been operating in Algeria since 1973 in both mechanical drive and power generation applications.
  6. MEDGAZ currently has five partners: SONATRACH (36%), CEPSA (20%), IBERDROLA (20%). ENDESA (12%), and GAZ DE FRANCE (12%).
