Petrobras has launched a tender to contract key subsea umbilicals to support production at its flagship pre-salt developments in the Santos basin.

Two sources told Upstream that Petrobras invited contractors including Prysmian, Aker Solutions, MFX, TechnipFMC, Nexans and Oceaneering — through its subsidiary Marine Production Systems — to submit commercial bids on 30 December.

Petrobras plans to contract 67.2 kilometres of steel tube umbilicals (STUs) and associated gear to serve one or more pre-salt projects.

Besides the manufacture and supply of STUs, the workscope includes freight, technical assistance services, installation, supervision and assembly, and pipe reels for storage.
