PDStrip (Public Domain Strip) computes the seakeeping of ships and other floating bodies according to the strip method. Responses in regular waves are given as response amplitude operators.

PDStrip has been written in Fortran 90/95. It can handle unsymmetrical bodies including heeled ships. Forces on fins or sails can be taken into account.

Powersea predicts the motion of a planing boat in calm water, regular or irregular seas. With specified forward velocity or thrust and the shape of the waves or wave spectrum it calculates the hull’s motion including surge, heave and pitch displacements, velocities and accelerations.

SeaFEM is a platform for seakeeping analysis, offering a suite of tools for the analysis of the effects of waves, wing and currents on naval and offshore structures also for maneuvering studies. The software is integrated part of Tdyn suite.

The Ship Motions is a program for predicting regular wave responses and statistical information from an initial hull geometry. The motion can be calculated with five degrees of freedom: heave, sway, roll, yaw and pitch.

ShipmoPC is a strip theory-based, frequency domain seakeeping code capable of computing the six degrees-of-freedom motions of a monohull with forward speeds in regular as well as irregular seas of arbitrary headings. It permits the user to specify any combination of the following appendages: bilge keels, skegs, fin stabilizers, anti-rolling tanks propeller shaft brackets and rudders.

SPH-flow is a meshless Lagrangian solver for simulation of flows with very high dynamics such as impact, sloshing, slamming. It is also suitable for flows over complex geometries, flows around moving or deformable bodies or the simulation of coupled fluid structure interaction problems.

SPLASH is a 3D nonlinear free-surface potential flow panel code for hydrodynamic design and analysis of marine vehicles. Applications range from performance predictions for surface vessels and submarines, to prediction of hydrodynamic loadings for structural analysis of ships.

Subflo 2 is an unsteady hydrodynamic analysis code for the prediction of vortex-induced hydrodynamics of maneuvering submersible vehicles.

Swan-2 is a computational fluid dynamic program for the analysis of the steady and unsteady zero-speed and forward-speed free surface flows past ships which are stationary or cruising in water of infinite or finite depth or in a channel.

Swan-2 implements a fully 3D approach based on the distribution of Rankine sources over the wetted and the free surface. The linear free surface condition is satisfied, while it has the capability of taking into account the non-linear Froude-Krylov and hydrostatic forces.

WaveLoad performs seakeeping analysis to predict motions, hull pressure distributions and sea loads for ships with variable forward speed in waves. Mono or multi-hull ships can be modelled in regular or irregular waves and any sea state. WaveLoad is available in both frequency domain and time domain versions.

VisualSMP is a suite of tools used in the prediction and analysis of a ship's sea-keeping and loads characteristics.

VOF-flow is a 6 dof free surface Navier-Stokes solver adapted to complex geometric simulations for marine problems.

Wadam is a general frequency domain hydrodynamic analysis program for calculating wave-structure interaction for fixed and floating structures of arbitrary shape. Airy wave theory is applied and results are presented as complex transfer functions or as deterministic results for specified phases of the wave. The radiation-diffraction part of Wadam is based on software developed by Massachusetts Institute of Technology.
