Successful transportation of VOX DUBAI section
Category: Press release

Block 1200.1 with the two main engines measuring 30 x 31 x 9 metres,
approximate weight 1,260,000 kg
On 3 July 2008, the two main engines of the VOX DUBAI, together with block 1200.1 and the engine and pump room, were moved from a floating pontoon into the IHC Dredgers shipbuilding hall in Kinderdijk.
The 31,200 m³ trailing suction hopper dredger VOX DUBAI is the largest ship of its kind ever to be built in the Netherlands. It will be 200 m long, with a beam of 31 m and a moulded depth of 17.5 m, putting it into the jumbo hopper dredger category (hopper capacity of 17,000 - 24,000 m³) that includes only 12 vessels worldwide. The ship has a dredging depth of 70 metres and it is being built for Van Oord. It will be launched in the spring of 2009.
The keel was laid on Friday, 30 May 2008 at the IHC Merwede yard in Kinderdijk. After preparations lasting more than a year, that was the start of actual building work on the vessel. During that time, the technical details of the project were worked out, and the first sections were built at VSH in Heusden, which is a subsidiary of IHC Merwede. The VOX DUBAI consists of more than 200 sections. The three midship which are intermediating the deck sections together are, for example, 100 metres long and 31 metres wide, with a depth of 9.6 metres. That is larger than a 2,500 m³ hopper dredger! The main engines each measure 10 x 5 x 5 metres and generate a combined power of about 28 megawatts, enough to provide 44,000 people with electricity. That's as many people as live in a small town.

Additional information
Increases in scaleIn 1990, the largest trailing suction hopper dredger had a hopper capacity of 12,000 m³; up-scaling has now passed through a number of stages, resulting in 'jumbo' trailing suction hopper dredgers with capacities of 17,000 - 24,000 m³. Twelve of these ships are now in operation around the globe. This is not the end of the up-scaling process, despite the limitations associated with the large dimensions and draught. Up-scaling is leading to both the construction of even larger vessels ('mega-vessels') and the extension of existing ships.
The table below illustrates the process. The VOLVOX TERRANOVA is the largest dredging vessel ever built (in 1997) by IHC Dredgers in Kinderdijk. The assignment for both ships came from Van Oord nv.
