The MO4 onboard system is installed on the vessel bridge. The system accurately and clearly shows how the incomming weather will impact your trip or operation. MO4 uses a state-of-the-art ship motion algorithm combined with a detailed 2D spectral weather forecast, to generate a forecast of the ship motions of unrivaled quality. The forecasted motions are presented in an intuitive and simple way, to aid the crew of the vessel to make decisions based on the best available data. Motion sensors are used to provide confidence in the forecasts.





“This service truly changed our way of working. We feel more confident and see better workability as a result!”


  • Get an intuitive and clear insight in the near-future workability
  • Optimize your workability by choosing a favorable heading and operational sequence
  • Increase your workability by 20% or more.
  • Provide clarity in the decision making process
  • Easier to use on board than conventional engineering reports


Current methods used in the decision making process for marine operations often result in relative low workability. Assumptions made in the engineering phase do not always agree well with the actual offshore situation. MO4 allows the vessel staff to instantly re-assess the most relevant engineering results based on actual data. Thereby reducing risk, increasing workability and enhancing the overall project performance.

Improving sustainability in Offshore operations

The transformation towards more sustainable energy production is having a marked impact on the offshore sector, with a growing focus on ensuring more sustainable operations. At the beginning of 2020 the International Marine Organisation set new guidelines for the use of fuels to curb sulphur emissions, setting the shipping industry on a greener path. Optimising […]

New workability parameters for offshore operations

The complexity with Offshore contracts Offshore contracts are notoriously hard to perfect. Workability depends on various factors that cannot be controlled, the weather being one of them. When looking at what should and shouldn’t determine workability, parameters such as weather and wave height are used, which leaves operators vulnerable to exceeding time and cost due […]

Who is MO4

The offshore industry is starting to change. New technology is emerging that make greater collaboration and clearer decision making possible. We are starting to work side-by-side with experienced Captains and stakeholders to improve safety, create and maintain cost reductions and provide workability forecasts with previously unachievable accuracy. Who are we and how are we doing […]
