DECK ERECTION OVER LAND
(North and South Transition Spans)
Fabrication of the deck over land (for North and South
Transition Spans) was performed by Italian fabricator
Cimolai under the EPC Contractor’s supervision (IHI-
ITOCHU JV) in Italy and transported to job site on sea
barge named Archimedes.
The transition spans are 120m long on the north side and
105m long on the south side between the supporting
points each on the side span pier and the transition span
pier.
The transition span deck is divided into eleven deck
segments on the north side and eight deck segments on
the south side to suit the planned fabrication,
transportation and erection equipment capabilities. The
total weight of deck segments is 1915t for north side and
1620t for south side.
Transportation of the North and South Transition Spans
The fabricated North and South transition span deck
segments were shipped to the site on a barge from the
fabricator, Cimolai in Italy. The sea Trip from San Giorgio
di Nogaro Quay to Jobsite and is approx 1,300 Nautical
Miles and shown in below figure 38.
All the phases of loads when transferred from the factory
to the barge, sea transportation and unloading were
studied in detail with load in analysis.
All 19 segments for the north and south transition spans
were stacked in multiple tiers on the same sea going
barge named “Archimedes” The Archimedes barge was
towed to the job site by a multipurpose tugboat named
“Garibaldo” The shipping plan was as shown in Figure 39
below.
