Most northern European fabrication yards rely on work from offshore projects at their doorsteps. The same used to apply to yards in It- aly, until environmental legislation
brought the country’s offshore feld activity to
a virtual standstill.
The situation caused some engineering
groups to fold. However, Rosetti Marino,
based in Ravenna on the Adriatic coast,
was not dependent on the domestic sector
alone, having supplied topsides and jacket
modules and structures to felds throughout
the Mediterranean Sea and offshore West
Africa. At the same time, the company was
not wholly reliant on platform construction,
having also been established since the mid-
1920s as a naval and commercial shipbuilder, including offshore support vessels.
During the mid-2000s, the company decided to pursue fabrication work elsewhere,
capitalizing on the growing offshore activity
in the Caspian Sea by forming two joint ventures in the region. This led to several contracts ranging from a living quarters barge to
piperack and manifold modules, and culminated in 2009 with involvement in the hook-up and commissioning of the “D” drilling
island for the ultra-shallow water Kashagan
project offshore Kazakhstan, and fabrication
of associated offshore pig launch systems.
Around this time, Rosetti also bid successfully for the living quarter and process platforms for DUC’s Halfdan development in the
Danish sector. This was the company’s frst
North Sea job since the early 1990s, when it
supplied the drilling module for Agip’s Tiffany platform, now operated by Canadian
Natural, in the UK northern North Sea.
In 2009, Rosetti won a contract to build a
3,300-ton topsides with drilling module for
Talisman’s Auk feld redevelopment in the
UK northern North Sea. However, the proj-
ect was cancelled after design changes meant
the planned new facilities would be too heavy
for the existing Auk A platform to support.
Harsh environment upgrades
Rosetti’s oil and gas business unit today
can build complete platforms on an EPC
basis or individual platform structures. It
additionally performs sea transport, offshore hookup and commissioning, and upgrades to existing platforms. The 200-strong
multi-disciplinary engineering team is split
between the engineering department in
Ravenna and the Basis Engineering and
Fores Engineering subsidiaries in Milan and
Forli. Between them, they cover all typical
offshore design and fabrication needs.
The company operates two large facilities
for offshore construction in Ravenna harbor.
One, spanning 32,700 sq m (351,980 sq ft),
is used mainly for rolling of tubulars, pre-
fabrication of structural components, and
assembly of pressure vessels. Its prefabrica-
tion workshops are equipped with overhead
cranes (up to 40-ton capacity), while the
open storage area is served by a 35-ton gan-
