Home' Work Boat World : November 2009 Contents Although the global economic recession
rippling through the maritime industries has created unprecedented
challenges, UK-based South Boats'
Special Projects division has kept ahead
of the game, designing a new 20-metre
vessel for offshore UK Round 2 and
Round 3 site construction.
Built for Resolution Shipping (UK),
'Don Quixote' is the company's first
20-metre "South Catamaran Wind Farm
Supply Vessel". The catamaran will be
operated and managed by MPI Workboats
(UK) to facilitate the transport and
installation of offshore projects initially
in the UK east coast wind farms.
Twin UltraJet UJ575 waterjets coupled
to twin MAN D2842 LE4I 0 EDC diesel
engines, each rated at 809kW at
2,100rpm, power the South Boats' vessel.
This drive-line combination gives 'Don
Quixote' a displacement of 50 tonnes, a
sprint speed of just under 25 knots and a
fast cruising speed of 22 knots at 80
percent load. The thrust has been
improved with this jet/engine package for
powering through rough sea conditions
and for when the craft needs to push
against the wind farm towers.
The 20-metre catamaran design follows
on from existing vessels in class and
features the South Boats "Crew Bus"
superstructure design. A key feature of the
20m Cats design is the aft working deck
with an area of 52m2, yet also retaining
20m2 on the forward deck.
An Ultra Dynamics 3 Station JetMaster
control system is fitted to the vessel with
reverse deflector controls, multi-axis
joystick and back-up control levers at the
main helm position.
A Humphree Interceptor system
has been integrated with the UltraJet
UJ5755 to aid trim and performance
when carrying high payloads in heavy
weather while improving fuel economy
and reducing CO2 emissions.

Advances in MARINE ENGINES and PROPULSION SYSTEMS
Faced with ever increasing demand for its high quality
propellers, the management of Stone Marine Singapore has
invested in two new furnaces, which will increase the melting
capacity of the foundry in Singapore by over 50 percent.
The furnaces, which are currently being installed, have a capacity
of 1,800kg each, and together with the firm's existing furnaces, will
give a total melting capacity of approximately 9,500kg.
At present, most of Stone Marine Singapore's production of
high accuracy propellers falls in the 500 -- 2,500kg weight range
and, while it is expected that this will remain the situation for the
foreseeable future, the new furnaces will enable the company to
manufacture propellers up to 5,000kg finished weight.
Gerry Mcloughlin, Managing Director of Stone Marine
Singapore commented: "We find ourselves in the happy position,
particularly at this stage in the world's economic cycle, of having a
very healthy order book. In addition, several customers, impressed
by the quality of our products, have expressed a wish that we
supply propellers for their larger vessels. We shall be able to satisfy
this demand with the new furnaces and the other recent changes
we have made to our production facilities."
The investment in the furnaces in 2009 follows the considerable
investment made by the company during 2007 and 2008 on the
purchase of conventional and CNC lathes; combined, these
investments ensure that Stone Marine Singapore continues to have
"state of the art" production facilities capable of manufacturing the
highest quality propellers and associated propulsion equipment.
