Autohydro Pro hydrostatics and stability software is cutting edge technology
Autoship Systems Corporation (ASC) of Vancouver, Canada is
pleased to supply Incat Crowther USA, a passenger vessel
design company, upgrades to their Autohydro Pro
hydrostatics and stability software.
Autohydro provides naval architects with many important
tools for assessment and approval of passenger vessel designs.
Autohydro 6.4 included a major update to handle the SOLAS
2009 probabilistic rules for cargo and passenger vessels. With
soon to be released version 6.5, assessment of intermediate stages
of flooding per the probabilistic rules will be added and
Modelmaker will be enabled to allow the user to graphically see
penetrations and to print penetration calculations.
Other features in Autohydro 6.4 and 6.5 include: autoballast
feature, introduction to a new reporting tool, update to
"freesurface-moment", Modelmaker comes with new and
improved interface, part plot tool re-written and is now a menu
item in Modelmaker, automatic import of IGES models, user able
to export bulkhead definitions for Autohydro to use in its
calculations and compatibility with Windows 7.
Incat Crowther is a diversified marine design company with
offices in Sydney, Australia, and Morgan City, Louisiana, USA.
The company has been operating for 30 years and has over 300
vessels in operation. They have a history of developing
forward-thinking concepts in aluminium catamaran and
monohull vessel engineering and construction.
"Autoship Systems has always been from my experience at the
cutting edge of new technology for hydrostatics and stability
software programs. When I haven't been able to figure out a
routine or a run file, I've always found their Autohydro Technical
Manager to be a wizard at solving my issues", says Grant
Pecoraro, Incat Crowther Naval Architect.
Autoship Systems Corporation provides leading-edge
CAD/CAM software for vessel design and construction, on-board
strength and stability monitoring and customized load planning.

Remora HiLoad DP completes final sea trials
January 27, 2011 was a milestone in the development of the
unique Remora HiLoad DP as it completed its final sea trials
before live field implementation.
HiLoad is a revolutionary deepwater offshore loading
terminal, made possible by innovative vessel design and the use
of a cutting-edge Kongsberg Maritime Integrated Automation
Built at the Aibel Shipyard, Haugesund, Norway, HiLoad is
the first vessel in a new generation of generic offshore loading
systems that, through state-of-the-art technology, including
Remora's patented HiLoad Attachment System and Kongsberg
Maritime's IAS; which includes K-Pos Dynamic Positioning,
K-Chief marine automation, K-Bridge, and fire, safety, and
emergency shutdown system; can control the position of a
standard oil tanker that does not have its own thrusters or DP
system. This mobile system can be deployed at any field and
used for the safe and efficient transfer of oil from an FPSO to
any size and type of tanker, effectively replacing the need for a
The K-Chief automation system aboard HiLoad monitors and
controls the ballast, power management, thruster control,
machinery and bilge system. There are approximately 2,500 I/O
(signals) with field stations placed around the ship connected to
each other and the operator stations on the bridge via
redundant network. The IAS includes custom automatic ballast
sequences for docking and undocking of a tanker, which are
based on predefined sequences of valve and ballast pump
operation, with back pressure automatically controlled via
integrated PID controllers.
The K-Pos Dynamic Positioning system controls the position
of HiLoad when alone and when connected to an oil tanker
loading oil behind an FPSO. Because the application is brand
new, Remora and Kongsberg Maritime had to develop several
unique processes for the DP system.
"Early in the project several big challenges that needed special
attention were identified," said Pål Borge Korneliussen, Group
Manager, Application / DP & Manoeuvring Offshore, Kongsberg
Maritime. "The size of the tankers can vary from Aframax to
VLCC and because of this range we needed to develop a method
for calculating the hydro dynamic model for the different oil
tankers. We also had to consider the massive change in
displacement when HiLoad connects to a tanker.
"The most challenging operation for the HiLoad is connecting
or disconnecting the oil tanker. For the final sea trial using the
Aframax tanker 'SKS Tana' we implemented local reference
systems between the HiLoad and the oil tanker; Kongsberg
Maritime's own RADius and a Fanbeam system. This gave HiLoad
the possibility to determine the heading and the position of the
oil tanker relative to itself. A modified "Follow Target" function
made the approach towards the oil tankers safe.
"The size and shape of HiLoad is unique so there was a
significant effort to establish the correct parameters. All in all the
final 21 day sea trial was successful for the customer and for the
Kongsberg Maritime systems aboard HiLoad," said Korneliussen.
"There were a number of obstacles and challenges during the
project period, but through good communications, resource
management and highly skilled engineers Kongsberg Maritime
has made a successful delivery to support a cutting-edge concept
that can provide tangible improvements for offshore operations,"
added Project Manager Glenn Edvardsen.
The DNV approved HiLoad DP is the first of a planned series
of HiLoad vessels. Approximately 13 oil companies representing
the majority of the world's oil production observed the sea trials
and have shown interest in using the system.
