Siemens Energy Selected For BOG Compressor For NLNG Plant

Siemens Energy will provide a cryogenic boil-off gas (BOG) compression train to Nigeria LNG (NLNG) for its Bonny Island plant. Two Siemens Energy centrifugal compressors are also part of the order.

The technology will play a key role in providing additional BOG handling capability and spares for the existing system, the company said. A high-efficiency electric motor will drive the BOG compression train.
Manufacturing, testing, and packaging of the compression train will take place in Duisburg, Germany, with delivery slated for the fourth quarter of 2021.

Located in Finima, Nigeria, the Bonny Island plant has been in operation since 1999. Siemens’ partnership with NLNG and the Bonny Island project can be traced back more than two decades during the plant’s commissioning.

“With more than 20 years of safe and reliable production, the NLNG Bonny Island plant is a staple facility in the global LNG industry,” said Arja Talakar, senior vice president, Industrial Applications Products for Siemens Energy.

The reason for NLNG’s order comes from its decision to expand the Bonny Island plant by adding a seventh LNG processing unit and supporting infrastructure to increase its total production capacity from 22 million tonnes per annum (Mtpa) to 30 Mtpa.

The LNG facility is owned and operated by Nigeria LNG (NLNG), a joint venture between Nigerian National Petroleum Corp. (NNPC, 49%), Shell Gas (25.6%), Total (15%) and Eni (10.4%).

NLNG made a final investment decision (FID) on the expansion project in December 2019 and the seventh liquefaction unit at the site is expected to come on stream in 2024.
