This simple JavaScript calculator at link will allow you to compute any wave parameter (other than amplitude) from any other.

Java and Javascript calculators for density from temperature, salinity and pressure, sound speed from temperature, salinity and pressure. potential temperature from in-situ temperature and pressure, freezing point of seawater and more.

Octopus-Office is a hydrodynamic analysis program for the calculation of seakeeping characteristics of ships and other floating structures, with or without forward speed.

Odin is an underwater warfare simulation environment. It was designed to simulate the detailed interaction between underwater objects, whilst retaining a sufficiently fast running speed to enable multiple engagement  Monte Carlo effectiveness studies to be performed. It has ability to correctly handle multi-static acoustics within the underwater environment, using multiple sonars and reflectors.

The Ocean Engineering Research Center (OERC) is located within the Faculty of Engineering and Applied Science at Memorial University and has its own 57m x 4.5m towing tank for measuring ship resistance and ship motion.

The OpenFOAM (Open Field Operation and Manipulation) CFD Toolbox is a free, open source CFD software package which has a large user base across most areas of engineering and science, from both commercial and academic organisations.

OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics and electromagnetics.

OpenProp is software for the design and analysis of marine propellers and horizontal-axis turbines. This software is coded as a suite of MatLab m-files so it does require Matlab. OpenProp can be run using a simple graphical user interface, via the Matlab command line, or with a user-created script.

Opt4J is a Java-based framework for evolutionary computation. It contains a set of (multi-objective) optimization algorithms such as evolutionary algorithms (including SPEA2 and NSGA2), differential evolution, particle swarm optimization, and simulated annealing.

The Department of Marine System Engineering of Osaka Prefecture University offers research programs concerning marine system planning, marine transportation, marine space utilization, marine resource development and marine environment, on the basis of hydrodynamics, structural engineering, computer science and systems engineering.

Osaka University has a department of Naval Architecture and Ocean Engineering.

Osmosis computes the temperatures in near real-time and handles in thermal calculations the surface emissivity as a function of wavelength, temperature, and orientation of an optical beam incident upon the surface. Osmosis performing 1D optimized thermal modeling.

It was initially developed for testing the effectiveness of methods for increasing the infrared stealthiness of ships, i.e. for reducing their infrared signature. This implies computing the evolution of these signatures with time. Compared to other softwares assuming constant emissivity, Osmosis uses parametric emissivity. The emissivity is function of the surface temperature, the direction of arrival of the IR wave, and the wavelength.
