Saudi Border Guard has acquired two Damen cutter suction dredgers (CSD 450) for harbor maintenance duties.

Two CSDs 450, with a maximum dredging depth of -12 m and a mixture production of 3,000 m3/h, which were to be fitted out with an extensive list of options, containing an accommodation unit and positioning, navigation and communication equipment.

Except for these, the independence of the dredgers was assured adding the anchor boom installation, meanwhile, the efficiency was boosted by adding a spud carriage pontoon.

The delivery also included two complete dredging packages.

These packages consist of both stationary dredgers plus their floating and shore pipelines, a full system of spares, and training. This training will be given to the crew on the job.

The cutter suction dredgers will be based at different border guard stations in the Kingdom of Saudi Arabia, Jeddah on the Red Sea and Dammam in the Gulf Area.

They will perform various maintenance dredging jobs independently, like clearing the areas at jetties and keeping harbors to depth.

Great Lakes Dredge & Dock of Oak Brook, Illinois is going to start one more season – the third of six – of clearing out sediment from the bottom of Lake Decatur.

As Engineering Services Coordinator Jerry Stevens, crews have been working this week to reassemble the dredge operation as they prepare to resume dredging Friday, April 1st.

“We have about three more months in the Big Creek Basin, and we will also start in Sand Creek, which will take about a year to complete,” Stevens said.

The dredging crews have removed around 2.8 million cubic yards of sediment out of the planned 10 million cubic yards till now.

By the time the project wraps up in 2019, Lake Decatur should have an increased water capacity of 30 percent, which equals about 72 days of additional drinking water.
