The dataset on offshore pipelines in the European waters was created in 2017 by Cogea for the European Marine Observation and Data Network (EMODnet). It is the result of the aggregation and harmonization of datasets provided by several several EU and non-EU sources. It is updated every year, and is available for viewing and download on the EMODnet web portal (Human Activities, https://emodnet.ec.europa.eu/en/human-activities). The dataset contains lines representing the actual routes of offshore pipelines (where available) in the following countries: Croatia, Denmark, Estonia, Finland, Germany, Ireland, Netherlands, Norway, Poland, Russia, Spain (Andalucía), Sweden and United Kingdom. Each line has the following harmonized attributes (where available): code, name, status (abandoned, active, application submitted, not in use, planned, pre-commissioning, proposed, under construction), medium (air, chemical glycol, chemical methanol, chemical n/a, condensate, control, cooling water, gas, geothermal heating, hydraulic, mixed hydrocarbons, oil, other fluid, sewage, water), operator, size (inches), length (metres), year, from and to locality or facility, country code, country name and notes. Compared with the previous version, this new version includes updated data from German BSH-CONTIS source.
