In August 2010 the Heerema Fabrication Group was awarded the Engineering, Procurement and Construction of the Ensign Wellhead platform. At the end of August the construction of the topside and jacket started at HFG’s yard in Hartlepool. In August 2011 the construction was completed.

HFG  Engineering was responsible for the engineering, which process was already partly completed at contract award. However, as a consequence the scope increased 3 fold, which created a lot of challenges to minimize impact on the fabrication proces.

The topside is a three-level stack construction comprising a cellar deck, mezzanine deck and weather deck, as well as a helideck. The topside has been constructed at Hartlepool's Victoria Dock facility. The jacket was built at our Hartlepool's Greenland Road facility.
