Mexilhào gas field

Project description :

• A Petrobras (Petróleo Brasileiro SA) project: Mexilhão gas field in the Santos Basin off the coast of the state of São Paulo

Customer challenges :

A particularly challenging project …

• due to high temperatures (+130°C at the well heads)
• due to high water pressure (10,000 psi)

… which require very thick steel tube walls

Nexans' solutions:

• Two different umbilical designs to connect the fixed platform to the subsea manifold and the manifold to the individual well heads
• Total length of umbilicals: around 59 km
• These umbilicals will be used to provide electronic control of systems on the seabed and hydraulic and chemical liquid injection
• Manufacturing to be done at Nexans plant in Halden, Norway
