Transporting the Admarine 6 was a huge challenge, due to the extreme loading draught of 8.01 metres caused by the 3.8 metres protruding spudcans . To overcome this extreme protrusion, the full 7.000 mt cargo had to be positioned 4 metres above the carriers main deck on a custom-made grillage.
Well before the Xia Zhi Yuan 6 arrived, DOC had pre-manufactured this supporting grillage with their subcontractors. Upon arrival in Sharjah it took two welding teams, three mobile shore cranes and nineteen flatbed trucks less than one week to install the grillage under DOC’s supervision. Once the HLV left Port Khalid, DOC’s towmaster left from Hamriya port for the wet-tow part of the cargo. The following day at daylight, the float-on was performed with the tugspread operating with a 1 metre margin, whilst the Admarine 6 only had a 20 cm margin. Once loading was confirmed within 2 cm spot-on by the divers, two welding teams boarded the vessel for combined spudcan repairs as well as the special designed seafastening.
After a relatively windy passage the Xia Zhi Yuan 6 and Admarine 6 arrived in Abu Zenima, where the DOC team boarded the vessel again. Cutting of the seafastening and preparations for the float-off were performed in record time. Without any damage, the Admarine 6 and tug spread were successfully handed over to the owners by DOC.
During the entire project DOC was not only in charge of the full project management, engineering and preparations, but also supplied the superintendent, towmaster, diving and welding teams, and acted as broker for the transport vessel.
