Specialist Software Solutions

Royale Oceanic is at the forefront of the design and development of software solutions specifically for the maritime sector. Our team have created a series of packages including:


A computational fluid dynamics package called BASIN for the analysis of generalised hydrodynamics problems. BASIN utilises a fully non-linear time-domain boundary element approach to calculate the motions & loads for one or more vessels. The method can be applied to a wide variety of problems, including:

  • Non-linear seakeeping in regular or irregular seas with or without forward speed
  • Wave resistance in flat water
  • Added resistance and added loading in waves
  • Interaction between multiple vessels


We write, market, support and operate the industry leading manoeuvring simulator MATHMAN, which is used for the simulation of ship manoeuvring and track reconstruction. It is also used as a computerised towing tank for port and channel design studies and for collision and grounding risk studies.

The MATHMAN manoeuvring simulation package has been developed by Royale Oceanic, with particular emphasis on its use as a tool to assist in the investigation and reconstruction of collisions and groundings. MATHMAN allows consistent, comprehensive and accurate reconstruction of vessel tracks, including all external forces, such as wind and current, as well as an accurate representation of control input, such as engine and rudder orders. In addition to track reconstruction, the program also enables checking of the consistency of evidence, e.g. between a course recorder trace and log book, as well as the possibility of investigating potential avoidance manoeuvres and other “what if” scenarios. Expert evidence based on MATHMAN has been presented on numerous occasions.

Royale Oceanic worked with GRC Ltd to integrate MATHMAN as a design tool into GRC’s PARAMARINE naval architectural design package, which is used by the UK Ministry of Defence (MOD), amongst others. We have also developed TRIMAN, which is used by the MOD to predict manoeuvring characteristics for the MOD’s ‘TRITON’ trimaran frigate project.


HYDAS – a fully integrated software suite for the analysis of intact and damage stability (including progressive flooding) longitudinal strength, motions and grounding which interfaces with other design and analysis tools. Probabilistic Damage Stability calculations can be undertaken for Superyachts using our in-house HYDAS suite or NAPA.

Other specialist software systems include:

LOADCALC – a simple to use shipboard loading and stability system.

SALVCALC – a self contained PC loading and stability system, with the ability to analyse damage and grounding forces, suitable for ISM applications and with the ability to analyse grounding forces suitable for ISM applications.

EQUIMOOR – for static and dynamic analysis of ship mooring systems.

We also a have a number of proprietary codes, including:

ANSYS – a general purpose code for carrying out Finite Element Analysis investigations into the static, dynamic and non-linear behaviour of structures.

OSCAR and SCORES 2 – for investigating ship and offshore structure motions and hydrodynamic loadings.

3-D STUDIO – for the development of 3D computer animations, including realistic light and sound. This may be interfaced with MATHMAN to provide ‘the view from the bridge’ or other animated reconstructions.

CRYSTAL BALL – for probabilistic analysis, using the Monte Carlo simulation method.

MATHCAD – a general symbolic solver permitting on screen manipulation of mathematical equations.

CAD – various CAD software packages are supported including NAPA, Rhino, Microstation and Autocad.

NAPA – for the analysis of intact and damage stability.

Probabilistic Damage Stability calculations can be undertaken for Superyachts using our in-house HYDAS suite or NAPA.

Safety Services


Safety and quality programmes adopted by the maritime industry have become increasingly sophisticated in recent years. However, the prevention of accidents and environmental damage still depends largely on the ability of the Superyacht’s crew to respond promptly and professionally in a crisis situation.

Working in the front line

With over 40 years of experience, we provide training where it counts – on board the vessel. Training and audits performed during the course of the voyage focus on the personnel, systems and equipment available to respond to external inspections and emergencies.

Flexible Shipboard Services

We provide cost-effective, voyage based solutions to training and onboard audit requirements. Each of our clients has distinct individual needs. We make every effort to match these needs with the individual expertise of the consultant, or team selected for the task.

Compliance with regulatory and commercial requirements

Safety Services consultants perform shipboard safety, quality and environmental audits to help ensure the vessels meet regulatory requirements and avoid costly delays and detentions. Our consultants conduct over 200 technical and safety audits on board vessels of all types each year. They concentrate on the timely identification of problems which could have significant safety and commercial consequences.

Our clients benefit from a broad range of training options

  • Safety Procedures Onboard
  •  Accident Prevention
  • Emergency Response
  • Fire Prevention and Fire Fighting
  • Rescue and Resuscitation
  • Abandon Ship and Survival at Sea
  • Enclosed Space Entry
  • Breathing Apparatus
  • Safety Equipment Use and Maintenance
  • ISM Code Requirements
  • Ship/ Shore Interface
  • Pollution Avoidance
