Sea Conditions

Choose from a range of standard sea states modeled using the ITTC standard Bretschneider Spectrum. Alternatively, define your own custom spectrum for your operational area.

Rapid Results

Quickly calculate the heave response of your platform model, including both added mass and damping calculation in accordance with DNV RP-H103. Armed with only characteristic dimensions of your platform, heavecalc can produce RAO and response spectrum plots, for multiple platforms simultaneously. The entire dataset can be exported to .xls format if required.

Written in Python Programming Language

Code has been written with extensibility and the future in mind. The aim of this initial project is the analysis of heave motion of concept semi-submersibles. However, there is scope for the inclusion of surge and sway motions, and a broader range of platform types in future.
