PC-BASED SOFTWARE SYSTEMS
Design Systems & Technologies' PC-based software can be categorised
in three groups: Design and Analysis, Ship Production and Ship Operation.
Compatibility between systems and the ability to add programs to
a practice as projects demand them is one of the key attractions.
FastShip, GHS, NavCad, ShipMO, Maestro and Esti-MATE are used for
preliminary design and analysis.
FastShip (Proteus Engineering Inc) is a hullform design and surface
modelling program that can also be used for superstructures and
appendages. It has intact hydrostatic and stability calculations
and interfaces with many stability, structures and hydrodynamics
programs. First released in 1983, FastShip is now onto version 5
and includes parametric and Wizard modules to help in automatically
producing new hulls from a set of parameters, such as ship type,
overall dimensions, displacement, LCB location, form coefficients
etc. Hulls can also be designed from scratch, derived from library
hulls or by importing offsets. Easily learnt, FastShip includes
industry-standard interfaces IDF, IGES and DXF.
GHS/Win (Creative Systems Inc) is a General Hydrostatics and Stability
package. The most powerful stability calculator in the microcomputer
world, GHS goes beyond static stability calculations and checks
for positive stability in all conditions. It supports variable density
cargo, staggered heel/flotation plane conditions as well as compartment
NavCad (HydroComp Inc) is a parametric resistance and propulsion
prediction system and models can include hull, appendages, propeller
and engine (resistance, power, thrust and torque) as well as 'non-ship'
effects such as waves, wind, shallow water blockage and towed/pushed
NavCad also has facilities for correlated alignment calculations
(to towing tank data, other experimental sources, proprietary databases
Maestro (Optimum Structural Design Inc) is a finite element analysis
based structural optimization package which, thanks to its fundamental
coarse mesh approac, is uniquely suitable for the study of reinforced
shells such as ship and submarine hulls and superstructures, offshore
rigs, semi-submersibles etc. Selected areas can be evaluated using
a fine mesh.
Esti-MATE (SPAR Technologies) is used by small and large organizations
to predict and manage the cost of shipbuilding. It uses parametric
and database technology to integrate constantly changing information
as well as an item-by-item approach. Interfaced to ship production
programs such as ShipCAM and CAD-Link it is fully customizable and
suitable for newbuilding or refit/repair jobs.
Of most interest to CAD users who are already familiar with AutoCAD
or Microstation are the PC-based ship production software packages,
especially ShipCAM 97, NauSHIP and CAD-Link 98.
Compatible with Microsoft Office for producing documentation, or
importing into databases and spreadsheets for calculations, the
ship production programs offered by DS&T allow for every piece
of the steelwork (for example) to be given attributes. These may
vary from post-processing codes for shipyard teams to which grade
of steel the part is to be cut from. Classification Society approval
drawings are generated from the 3D model, making any necessary modifications
running throughout the design relatively painless.
Danese has scrutinised the time sheets and figures for projects
they have worked on and is confident that a third of the design
and production time is saved in the concurrent process, compared
to the traditional stage-by-stage method of working.
ShipCAM 97 (Albacore Ltd) focuses on the fast and accurate production
of shell-related fabrication data.
Unmatched in plate development (surface-based as opposed to traditional
frame-based methods), inverse frame bending calculations (transverse
and longitudinal), automatic cut-out placement capabilities, ShipCAM
also offers all traditional shipbuilding functions such as shell
expansion, template forming, pin-jigs, weights and CG calculations.
Double curvature plate deformation is quantified exactly and plate
formability can be checked on screen, interactively, thus allowing
plate size optimisation.
ShipCAM supports most industry data exchange formats and database
links integrate it with steel production modelling programs such
as NauSHIP and CAD-Link:
CAD-Link 98 (Albacore Ltd) is an AutoCAD-based steel production
modelling PC program expressly developed for the small to medium
shipyard. It has database links, CAD assisted nesting, structural
modelling, basic piping and NC cutting interfaces and in its 3D
solid element structural element approach is an industry leader.
CAD-Link provides the tools to make 3D modelling as easy as 2D drafting
and, having been thoroughly tested with ShipCAM users worldwide,
it is established as an effective tool for all stages of ship production
Perception (SPAR Associates Inc) is the leading tool for planning,
scheduling and controlling the many elements involved in the production
process of ship manufacture. Based on client-server tecnology it
is a completely modular package, easily customizable to specific
The system comprises Esti-MATE, mentioned earlier, Work-Pac, for
tracking cost and work performance, Mat-Pac, to manage stock, purchasing
and delivery and Pert-Pac which dynamically maintains resource allocation
and scheduling, including automatic re-assignments at tagged event
PropCad (HydroComp and Design Systems & Technologies sarl) allows
the user to define a propeller in detail and to produce both a fully
dimensioned construction drawing and a complete offset table suitable
for the construction of a foundry plug.
It includes several parametric propeller libraries or can define
arbitrary shapes or a combination of the two. Class strength rule
calculations are supported.
Onboard operations/monitoring programs offered by DS&T include
Smart Engine and GLM while PropExpert aids with the choice of a
PropExpert (HydroComp Inc) is a Windows 95 software tool for the
selection and analysis of propeller systems for workboats and yachts.
Developed for the engine/propeller manufacturer and dealer market
it allows te user to select and match engines and propellers for
a given hull type and operating profile.
Smart Engine (HydroComp and Design Systems & Technologies sarl)
is a performance, display voyage analysis and propulsion management
software tool designed for onboard or onshore use. It addresses
both strategic and tactical issues from real-time course and throttle
settings to layup scheduling and a complete operating database is
generated for comparative analysis.
GLM (Creative Systems Inc). General Load Monitor is an onboard stability
monitoring system for use by the vessel operators and is a special
configuration of the aforementioned GHS. Using true ship geometry
for real-time calculations, including wind heeling, cargo shifting,
damage and grounding situations GLM can assess longitudinal strength
in any condition Installed on dozens of ships and easily translated
into any language it is perfectly suited for preloading and unloading
calculations and real-time operations management.
