A recent change to the IMO rules
governing damage stability requires
naval architects to use a probabilistic
approach to damage stability for all
passenger and cargo vessels over 80
metres in length.
To assist naval architects in achieving
this compliance, FormSys has released a
new version of Hydromax, the stability
module within the Maxsurf suite of
software. The new Hydromax PD module
will assist with calculations in accordance
with these new SOLAS regulations. The
probabilistic damage approach aims to
provide a more accurate measure of the
vessel's level of safety and ability to
survive damage than the previous
deterministic assessment, which
essentially involved calculation of certain
characteristics of the vessel's GZ curve.
The probabilistic concept is based on
statistical evidence concerning what
actually happens when ships collide, in
terms of sea state and weather conditions;
extent and location of damage; speed and
course of ship; and whether the ship
survived or sank.
After a hull model has been defined in
Maxsurf, it is loaded into Hydromax and
compartmentation is defined.
The user defines the location and
extents of the damage zones they wish to
consider. Hydromax then calculates the
factors for each zone.
The new probabilistic calculation
functions in Hydromax PD have been
validated using worked example problems
provided by SNAME, the US Society of
Naval Architects and Marine Engineers.
These new functions allow naval
architects to ensure stability compliance
used the same graphical, interactive tools
found in the rest of the Maxsurf suite of
naval architecture software.

With its share market surging and property prices hitting new
highs, the Hong Kong economy seems to have completely
shrugged off the Global Financial Crisis.
While parts of the shipping sector, most notably containers,
have suffered badly thanks to the GFC, many others have
continued to flourish.
"As the most efficient gateway to China, particularly southern
China, Hong Kong is riding the wave of China's almost uniquely
strong economy," said the organiser of the China Maritime
Exhibition, Kishore Navani.
"This continuing economic boom is certainly good for the
wider maritime industry," said Mr Navani. "We are certainly
seeing this reflected in the great interest being shown in China
Maritime which will be held in mid-March."
"The ship and boat design, building and equipment market
has, thanks to the GFC, become much more competitive than it
was for the previous two showings of China Maritime in 2006
"We are seeing this very clearly in the much stronger interest
being shown in the event by Chinese mainland ship builders and
suppliers," Mr Navani explained.
China Maritime will be held in Hall 5G of the Hong Kong
Convention and Exhibition Centre in Wanchai from Tuesday,
March 16 to Thursday, March 18.
