Ship Repair & Conversion
Hydrex Team Performs
Underwater Work On Saipem
This past summer marked the entrance of large crane vessel Saipem 7000 into
Botlek Harbor of Rotterdam. Within hours of its arrival, Hydrex's diving and repair crew boarded the vessel to carry out underwater servicing work, which required extensive dismantling of the vessel's thrusters.
The Hydrex team, which did research prior to the Saipem job, removed some the vessel's large thrusters. Since the available water depth was not sufficient to allow for the lowering and safe pas- sage of them, dredging work was the first underwater task to be completed.
Hydrex's underwater ship repairers dug a trench using a six in. salvage pump.
Five days after intense dredging and removal of debris and rocks — a crater of 5 m deep was created under one of the four main propulsion thrusters.
Concurrently, Saipem's engineers had disconnected the 70 ton thruster onboard, which was then lowered under- water, and with the help of Hydrex divers, hoisted to the surface so that maintenance work could be performed.
The vessel was then transported to a different location beneath the crane mammoth to commence dredging under one of the six DP retractable thrusters.
Access space had to be created for the installation of a large cofferdam over the thruster-garage.
Exact positioning and installation is required to install these cofferdams. The team also removed the vessel's heavy lower gearbox of thruster number five.
The removal was carried out by the smallest crane vessel in the port of Rot- terdam due to the difficulty in having to pass under Saipem's bracings.

Abu Dhabi Inaugurates New
Shiplift And Transfer System
Abu Dhabi Ship Building (ADSB) commissioned its new Syncrolift
Shiplift and Transfer System at a ribbon cutting ceremony on February 17.
The ceremony, which was presided over by Lawrence Holiday, ADSB's managing director, marked a major addition to the company's drydocking facilities.
The system allows for the lifting, building and repairing of vessels mea- suring 85 m and weighting up to 2,000 tons.
Regarding its ship repair activities,
ADSB will now be able to work on much larger vessels in three 85 m dry berths that were commissioned along with the shiplift system.
