to this project by Fagioli, which are the LR11350,
KOBELCO SL6000 and CKS 3000, along with
3 nos. Tadano GR80EX RT Cranes which were
used as support cranes. For the installation of the
heaviest items Fagioli is using its famous tower
lift and stand jacking system, being proprietary of
one of the biggest fleet in the world, synonymous
with safety and high capacity hoisting potentiality
(Picture 7). Fagioli Tower Lift system consisting of
4 nos 600 T strand jack system was also mobilized
and was dedicated for installation of the Acid Gas
Absorber, which was the heaviest equipment to be
installed, weighing up to 1.100T. Fagioli used a 66 m
high tower lift system to execute the operation. The
vessel with a length of about 53,5 m, was moved
into installation area by means of Fagioli SPMTs
: No. 76 axle lines ; three rows made of coupled
trailers (Picture 8) . Once in position the vessel was
hooked to Fagioli tower lift system provided on top
with No. 4 x 600 ton capacity strand jacks (Pictures

our partner for this project (GTA), was used as
tailing system. While Fagioli strand jacking system
was lifting the vessel, the crawler crane, used as Picture 7 - Fagioli tower lift and strand jacking system
