Oshima Shipbuilding uses Nupas-Cadmatic 3D technology | back to news |
| |
Oshima Shipbuilding Co. Ltd. launched a project to develop a
sophisticated three-dimensional (3D) computer-aided "upstream"
shipbuilding design system specifically geared for the primary process
from basic planning to basic design following the conclusion of a
newbuilding contract. The new system will be developed on the basis of
Nupas-Cadmatic software by adding new functions and improving its
specifications for Oshima. The shipyard already purchased Nupas-Cadmatic
3D ship design software earlier this year.
Two engineering firms, CIM Creation and SEA Systems, take part in the
project which is funded by the Ship & Ocean Foundation (SOF) Oshima has
also asked for the cooperation of Nippon Yusen Kaisha (NYK) and Nippon
Kaiji Kyokai (ClassNK).
In ship design drawing, much progress has so far been made in the
application of 3D computer-aided design (CAD) systems for the so-called
"downstream" design process from detailed design to production design.
However, most "upstream" design systems made available so far are
two-dimensional (2D). But 2D basic designs require specific professional
knowledge to read. For this reason, the first job to be done by
inexperienced design engineers is to learn decipherment of shipbuilding
drawings.
An Oshima official said that the project has been instigate by the
desire "to provide young people joining us in the 21st century with
design tools of the 21st century". It is aimed to "step out of the
present state where designing means 'drawing' and develop a tool that
allows the process of 'monozukuri (manufacturing)' to start from the
stage of designing," he added.
Specifically, what Oshima is aiming to develop is a system to design a
3D product model at the stage of basic planning. Such a model will help
even laymen to have a clearer image of a ship upon its completion. It
will make preliminary talks between a shipyard and a shipowner easier
and more efficient at the early stage of design work. It may also allow
design engineers and shipyard workers to check possible design flaws and
discuss specifics about actual work programs.
The Oshima official said that the projected system will facilitate
design work, improve work quality, enhance production efficiency and
help younger design engineers upgrade their skills faster. "Moreover,"
he added, "it will allow us to quickly verify designs from various
angles, giving birth to new ideas and creative designs."
The planned 3D "upstream" system will be one that will be fit for the
business model of Oshima, which builds bulkers of various types in large
numbers at the same yard rather than focusing on a single multipurpose
model. Oshima also plans to use the system to deal with all other
shipbuilding-related business in the future.
