Satellite accounts intend to increase the capacity of observation of particular phenomena. In Statistics Portugal they are often developed in partnership, seeking to complement statistical methods with the specific knowledge available in other institutions. The Portuguese Ocean Satellite Account (OSA) was developed in partnership with the Directorate General for Maritime Policy (DGPM), Ministry of the Sea.

The Portuguese OSA is based on the conceptual framework of the Portuguese National Accounts and is considered an adequate instrument to estimate the relative macroeconomic importance of the Ocean Economy in the Portuguese Economy. It also supports the decision-making and monitoring of national policies, namely the economic pillar of the National Ocean Strategy.

OSA is considered a useful and timely information tool. However, it is acknowledged that it does not cover all relevant economic information, particularly the value of natural resources and of sustainability of economic growth.
