ALE Crane Expedites P-74 FPSO Lifts in Brazil

ALE announced last week that it has performed the heavy lifting and installation of 40 modules, weighing up to 3,000t, onto the P-74 FPSO vessel in the south of Brazil. The company said the 3,000-t lift was the largest commercial lift by a land-based crane.

The modules ranged in weight and dimension, between 80t and 3,000t. ALE rigged its SK350 crane in its biggest configuration, with a 49-m ballast radius and a 4,000-t ballast. The main boom was a 130-m A-frame design on an 18-m wide base. The crane was equipped with a 4,000-t main winch and a 600-t auxiliary quick winch system. For the 3,000-t lift of module M09, ALE used the SK350’s 4,000-t winch system and high-speed slew. The crane was positioned at a radius of 86 m and extended to more than 142 m for certain lifting operations.

Throughout the project, ALE lifted a combined total weight of more than 36,000t (including tackle). The project lasted approximately 4 months.
