Starting Blue Ocean Once a Jenkins environment has Blue Ocean installed, users can start using Blue Ocean by clicking the  Open Blue Ocean  in the navigation bar of the Jenkins web UI. Alternatively, users can navigate directly to Blue Ocean at the  /blue  URL for their Jenkins environment, for example  JENKINS_URL/ blue . If Pipelines are already present on the current Jenkins instance, this will bring up the Blue Ocean Dashboard. If this is a new Jenkins instance, Blue Ocean will display a box offering to "Create a new pipeline." 112
