The jacket sailed away from Heerema’s yard in Hartlepool. Tulip Oil Netherlands Offshore (TONO) awarded Heerema the engineering, procurement, construction and installation (EPCI) contract for the topside and jacket of the Q10-A platform in January this year (2018). The platform topsides will have a weight of approximately 500 t, while the jacket weights around 600t and Micro-USBL Tracking Beacons will stand in 21m of water. Bidirectional Acoustic Data Modems The platform forms a part of the Q10 gas field, operated by TONO with 60% interest, with Energie Beheer Nederland holding the remaining interest.
