Modular construction (except tanks, tall vessels, large rotating equipment) Massive dredging works

A Very Challenging Project

• Development of major magnitude in all perspectives

• Largest ever built CPF

• Cyclonic environment

• Several components beyond current state of the art, will be qualified

• 40 year design life

• Highest HSE expectations

Build a project for 40 years of

safe and reliable operation
