Japan's Modec has brought in four big compatriot companies to help develop its FPSO project for Petrobras in Brazil.

It said Mitsui & Co, MOL, Marubeni and Mitsui Engineering & Shipbuilding (MES) will invest in the business, which will see a unit chartered to the oil major for 21 years.

Modec will be left with a 20.1% stake, with Mitsui on 32.4%,
