Incat Crowther has announced construction on the
first-of-type 70-metre fast crew catamaran (FCB) for Caspian
Marine Services in Azerbaijan.
Compliant with IMO HSC code and featuring a crew transfer
system consisting of DP2 dynamic positioning equipment
coupled with a stabilised access platform, construction of the first
vessel has commenced at Incat Tasmania with delivery scheduled
The vessel will operate as a fast crew transfer vessel for 150
offshore workers to multiple offshore installations, with the hull
design optimised for high-speed transits with noise, vibration
and climate control features limiting the seasickness of transiting
offshore workers. The vessel is also designed to operate in sea
conditions of 40-knot winds and three-metre seas.
Four MTU 16V4000 engines will power the vessel, driving
HamiltonJet HT-900 water jets to a service speed of 30 knots fully
loaded. Four azimuthing drop-down thrusters located forward
will provide DP2-class manoeuvring.
The vessel will be delivered to Azerbaijan via transit through
the Volga-Don Canal. Once deployed, CMS will provide crew
transfer and "hot shot" cargo services to platforms in such fields
as Azeri-Chirag-Deepwater Gunashli (ACG), the largest oil field in
Azerbaijan sector of the Caspian Sea.

Scientists from the ARC Centre of Excellence for Coral Reef
Studies (CoECRS) have shown that tropical corals have the
ability to fight back against acidifying oceans caused by
increased levels of carbon dioxide.
While the threat of coral bleaching from higher sea-surface
temperatures and direct human impacts still present significant
risks to the long-term prospects for coral reefs, the research
findings suggest that many corals have the ability to largely offset
the effects of increasingly acidic oceans.
"Using a new technique we were able to calculate the effects
of the acidification process on coral growth rate," says Professor
Malcolm McCulloch of the University of Western Australia and
Deputy Director of CoECRS.
"We've looked at many species of corals, including deep sea
corals, and found that almost all of them are able to reduce the
acidity -- or pH -- of the seawater they take in, adapting the
chemistry of this seawater and hence enabling them to more
efficiently extract this important material needed for building
their coral skeletons."
This process of 'buffering' seawater -- raising its pH -- only
takes up a relatively small amount of energy and provides
significant benefits to the coral. However Prof. McCulloch
cautions that corals still face serious risks from climate change.
"The rapid and often abrupt increases in ocean temperatures
that are expected over the next 100 -- 200 years are likely to
cause serious episodes of coral bleaching," continued
"Corals in this state will probably not be able to modify
the chemistry of seawater they take in -- an important part of
the skeleton-building process -- meaning that the effect of
ocean acidification would be felt at exactly the time when it is
Corals "can fight acidifying oceans"
