Offshore pipeline installation
This tender concerns the offshore installation of a 20 km long pipeline in the Maasgeul, including nearby dredging, pulling pipes via a pre-installed HDPE carrier pipe, and the placement of MLPP pipes with corrosion and thermal insulation and a concrete weight coating. The works include backfilling the dredged sections, excavating and backfilling non-dredged sections, the fabrication and installation of subsea spool pieces and the connection to the riser, as well as the fabrication and installation of the riser and associated clamps. A boat landing is optional. The tender also requires pre-commissioning activities from the onshore battery limit. The procedure is a competitive procedure with negotiation, aimed at a high technical and logistical level, with emphasis on safety, environmental protection, and precise planning. The contracting authority, Porthos Offshore Transport and Storage C.V., expects an integrated approach that complies with international standards for offshore construction and pipeline installation.
