IMO DCS – Data Collection System

DNV's IMO DCS services 

Plug in to a connected decarbonization journey

DNV’s DCS platform allows you to automatically transfer your operational data as frequently as you wish – removing the need for manual data aggregation and submission.

Emissions Insights, our unique emissions analysis tool that uses your ships’ DCS data, helps you then to turn tick-box exercises into valuable business information.

Emissions Insights provides you with real-time insights through powerful data visualization, and it also shows the preliminary CII rating of the vessels for the next three years based on the current data.

When it comes to creating the SEEMP Part III, our digital SEEMP Part III Generator is available to you as a DCS customer.
