An Ocean Developers License is legally required to create new Ocean for Techlog plug-ins. The license can be used for developing plug-ins for Petrel and Studio Manager as well. The licensing of the plug-in is the responsibility of the plug-in developer and the Ocean API provides classes to help with the licensing.
An Ocean Developers License provides access to all licensable modules of Techlog. When running Techlog using an Ocean Developers License the windows will be watermarked indicating that the Ocean Developers License is in use.
