Inhaúma Unit is working on the conversion of four VLCC (Very Large
Crude Carriers) ships into FPSO (Floating Production, Storage and
Offloading), of the future Platforms P-74, P-75, P-76 and P-77. Intended
for the Cessão Onerosa areas, in the pre-salt deposits of Santos Basin,
the platforms will produce up to 150 thousand barrels of oil, and compress
up to 7 million cubic meters of natural gas per day.
From a structural point of view, the conversion involves two main stages:
(i) replace the corroded plates of the ship’s hull and (ii) reinforce the
structure of the VLCC to receive the FPSO modules and equipment. The
Fast Track project aimed to design the main reinforcements in a record
time for the P-76. The intention was to execute these reinforcements in
China, at the same time as completing the hull repair. This resulted in
significant savings for the contract.
A Finite Element model performed in SCIA Engineer was built to evaluate
the stresses and design the reinforcements. Seven frames were modelled
with their adjacent frames: aft and fwd. A beam model was built to
determine the frames’ behaviour and to generalize the reinforcements to
the remaining frames.
