An arrangement of an unmanned and remotely operated production facility comprising a wellhead platform including a wellhead assembly having an X-mas tree, a flowline transporting hydrocarbon fluids produced from a well via said wellhead assembly to one or more consecutive process equipment(s), and further on to a destination via a transport line. Any process equipment and/or pipeline section located at a higher level than said outlet point from said wellhead assembly, is arranged to either drain back to the x-mas tree, or drain downstream to said transport pipeline by assistance of respective valves arranged along said flowline.
