Product Overview
* Hull Forms, General Arrangement
Hull forms definition
FSURF provides advanced tools to define the ship surface model based on NURBS formulation. Conventional or special hull forms such as mono-hulls, non symmetric vessels, multi-hulls and oil rigs can be modeled. Appendages of the ship, such as rudder, propeller or bilges can also be defined andtreated as a part of the ship main hull or as separated surfaces.
FORAN imports and exports surfaces from other formats (import and export IGES, export DXF, STEP, and other standard formats), and also from third-party proprietary formats.

FORAN general arrangement
The new module for the definition of the ship general arrangement supports the design and management of all ship spaces and setting upof the preliminary layout of equipment, weapons and accommodations areas.

Hydrostatic calculations
HYDROS features an extensive and intuitive set of applications to perform the complete calculation of hydrostatic values, Bonjean curves, deadweight scale, stability cross curves, freeboard, floodable and permissible lengths, sectional areas and trim diagrams.

Load – stactical stabilityLOAD performs the distribution of lightship weight, which can be estimated using the Lloyd´s Register criteria or defined by the user.
The following types of cargoes are handled: cargoes in defined spaces, modular cargoes (containers and pallets included), and others. Cargoes can be grouped to simplify the loading condition definition.
LOAD performs the required calculations to obtain theequilibrium waterplane for the ship in still water, in a trochoidal wave or in a sinusoidal wave. Asymmetrical loading conditions and the calculation of the necessary cargo density value to obtain required mean draft are also available.
It is possible to calculate the static and dynamic stability for heeling angles defined by the user or requested by Regulatory Bodies.
LOAD allows to carry out either thelongitudinal strength calculations with the ship in still water or in a trochoidal or sinusoidal wave. Shearing forces and bending moment curves are also obtained.

Damage stability
FORAN enables an accurate calculation of the flooding conditions (defined as combinations of initial situations and damage conditions) and damage stability according to the deterministic method.

Launching &Floating
Complete dynamic calculations and analysis of ship launching over slipway and floating from dry dock processes are featured in FORAN, including graphic representation and static and dynamic stability calculations.

Powering, Design of propeller, Sternframe & Rudder
FORAN estimates the towing resistance by a number of modern powering prediction methods, including some warship-specificones. It also provides several possibilities for propeller selection and analysis. The output information includes the main features of the propeller, power-speed curves, prediction for service and trial condition (including trawl condition in trawler ships) and open-water propeller diagrams. Propeller geometry in accordance with classification societies can also be calculated.
POWER allows to designinteractively the basic particulars of the rudder, the schematic ship stern profile and to estimate the manoeuvrability characteristics.

* Hull Structure

FORAN offers unequal solutions for the fast definition of a complete and accurate 3D model of the ship structure. All the work is carried out on the full-ship product model, which supports both the basic and detailed design stageswithin a single environment, simplifying the organisation and increasing the overall performance of the design process.
Tne of the most important characteristics of FORAN is the integration of the entire range of ship design disciplines. This property, combined with the seamless continuity between the basic and the detail stages of the design, together with the homogeneous development of all...
