Ulstein has announced the introduction of a
new dynamically positioned multipurpose construction vessel suitable for
shallow water operations.
Main design driver was to develop a very CAPEX friendly DP vessel with
good capabilities to support various offshore operations, including cable
lay and offshore construction.
The vessel offers an unprecedented combination
of deck area, accommodation and station keeping capability for a compact
vessel. This results in a very cost efficient platform capable of supporting
a wide variety of operations:
- Cable laying
- Offshore construction
- Shallow water installation
- Dive support
- Rock installation
- Salvage works
The mooring and DP2 (optionally DP3) station keeping capability, in combination
with the large endurance and adequate transit speed, ensure that the ULSTEIN
S182 can operate autonomously in remote shallow water and offshore areas.
“Given the CAPEX target that we have
set ourselves, we decided that speed will be a result of the design rather
than a design driver as it is in most designs,” says Edwin van Leeuwen,
Managing Director at Ulstein Design & Solutions B.V. “Speed requirements
often have a big impact on installed power, easily spiraling up vessel
CAPEX.”
More importantly, ULSTEIN has been able
to develop a very versatile workhorse that is capable of shallow water
DP operations (@ 4.5m draft) including beaching. She features a large and
strong open work deck suitable to accommodate up to 30 m ø carousel, large
cargo hold below deck and ca 10,000 DWT capacity. A main offshore crane
of up to 400 t can be located in the side of the vessel, while a passage
way below main deck is created between aft casings and accommodation, a
safety feature avoiding people having to cross the open work deck.
“As operational areas we mainly target
South East Asia, Middle East and Africa, but the vessel will of course
also be capable to work in the North Sea, where we see a good market for
cable lay operations." continued van Leeuwen.
