Built at Zamil Shipyard in the port of Dammam, two floating drydocks which will be used for naval vessel maintenance and repair work in Saudi Arabia, are being commissioned by Constructions Mécaniques de Normandie (CMN), a French ship design and construction company.
To assist in this process, Mammoet’s Saudi Arabia branch was recently contracted by CMN to launch the drydocks though a float-off operation, which was a first of its kind for the Kingdom. Mammoet undertook all the necessary engineering, procurement, logistics and other requirements based on a solution that entailed the use of a large floating dock which eliminated the traditional offshore float-off process and related logistics. This is said to have saved a significant amount of cost and time.
The floating dock, mooring and ballasting equipment were mobilised from the UAE, along with a specialised team, to carry out the operation. Each drydock, weighing 1,450 tonnes and measuring 85m x 34m x 11m, was transported from the fabrication facility to the quayside, then loaded out onto the floating dock using a Self-Propelled Modular Transporter (SPMT), before being floated off.
