Question 1

What is cgFLOAT used for?

Accepted Answer

cgFLOAT performs the dynamic analysis of long floating marine structures — floating marinas, floating breakwaters and floating (pontoon) bridges — computing their wave-induced motions, structural forces and mooring loads.

Question 2

Who develops cgFLOAT?

Accepted Answer

cgFLOAT is developed by RUNET (RUNET Software / RUNET Norway AS), a structural-engineering software company founded by Dr. Konstantinos Georgiadis and Greta K. Tenfjord, with offices in Greece and at Tennfjord, Norway.

Question 3

What types of structures can cgFLOAT analyse?

Accepted Answer

It is built for pontoon-based floating structures — floating marinas, breakwaters and bridges — with any pontoon arrangement and rigid or flexible connectors between the pontoons.

Question 4

How many degrees of freedom does cgFLOAT model?

Accepted Answer

cgFLOAT resolves the response in three degrees of freedom: sway, heave and roll. It is not a full six-DOF seakeeping/diffraction package for arbitrary 3D bodies.

Question 5

Does cgFLOAT perform hydrodynamic analysis?

Accepted Answer

Yes. It computes frequency-dependent hydrodynamic coefficients (added mass and damping) and generates wave loading from directional short-crested sea-state spectra such as Pierson-Moskowitz and JONSWAP.

Question 6

Can cgFLOAT calculate mooring forces?

Accepted Answer

Yes. From the computed sway displacements the program derives the mooring-line forces, which supports the design of the mooring and anchoring system.

Question 7

Does cgFLOAT support time-domain analysis?

Accepted Answer

Yes. In addition to a frequency-domain solution it offers a time-domain analysis using Monte-Carlo simulation of the wave loading, reporting ensemble maximum, mean and standard-deviation values of the responses.

Question 8

Does cgFLOAT design to a specific code or standard?

Accepted Answer

No. cgFLOAT is a hydrodynamic/structural analysis (simulation) tool; it computes motions, forces and mooring loads, but it does not state compliance with a named floating-structure design code. Code checks are carried out separately by the engineer.

Question 9

What outputs does cgFLOAT produce?

Accepted Answer

It produces mode shapes, frequency-response functions and graphs of displacements, bending moments and shear forces, with ensemble statistics from the simulation. Output can be shown in metric or Anglo-American units and exported graphically.

Question 10

Is cgFLOAT a new or mature program?

Accepted Answer

It is mature. cgFLOAT originated as a DOS program in 1981, moved to Windows in 1999, was updated for Windows XP in 2002, and gained graphical outputs and export in 2005, with ongoing maintenance by RUNET.

Question 11

Can I try cgFLOAT before buying?

Accepted Answer

Yes. RUNET provides a free trial (demo) version and documentation for cgFLOAT, along with free e-mail and telephone support for its software.

Question 12

Is cgFLOAT available in India through RAM CADDSYS?

Accepted Answer

RAM CADDSYS lists RUNET software — the publisher of cgFLOAT — in its product catalogue, so it can supply cgFLOAT to engineering teams in India. For a firm quote and the exact licensing scope, contact RAM CADDSYS directly, as the public listing covers the wider RUNET suite rather than cgFLOAT by name.
