The TAP consortium, based in Switzerland, said it was moving forward with the pre-qualification of potential contractors for the construction of the planned 540-mile gas pipeline through Greece, Albania, the Adriatic Sea and Italy.
"The scope of work for this contract is rather complex -- potential contractors must demonstrate very specific expertise in constructing natural gas compressor stations, as well as other multi-disciplinary energy infrastructure experience, including strong project management skills," TAP Procurement Director Knut Steinar Kvindesland said in a statement.
TAP said it issued a contract notice this week for the compressor stations needed in Albania and Greece for the transport of natural gas through the pipeline.
Companies interested in the contracts need to reply no later than June 16.
