Combining the versatility of a Multi Cat with the dredging performance of a DOP pump
Saudi Arabia-based Murjan Al-Sharq Marine Services purchased a Multi Cat 1908 in summer 2017. And, while Damen’s Multi Cats are well known throughout the maritime industry as being multidisciplinary vessels capable of tackling a huge range of jobs, this new vessel – named Murjan 40 – has taken that reputation for ‘all-round’ workability one step further.

The most notable modification that Murjan Al-Sharq Marine Services specified for the Murjan 40 was the installation of a Damen DOP Submersible Dredge Pump 250. With this addition, the client can add the specialist skills of shallow water dredging to its scope of maritime services.
“By adding a DOP pump to a Multi Cat, we instantly have a dredger – but a dredger which can also undertake the full range of tasks that a Multi Cat can do as well,” states Abdullah Natheer, Chairman of Murjan Al-Sharq Marine Services. Considering the company’s list of services on offer, this is an important point. Murjan Al-Sharq Marine Services does not limit its skills to the dredging sector; it also provides marine construction and maintenance, diving and subsea inspection services. Therefore, the Murjan 40 must also be able to work on these jobs too.
Yielding a 1,250 m3 per hour mixture capacity, the DOP 250 can either be deployed with the Murjan 40’s crane or over the stern with an A-frame. Considering the relatively small dimensions of the vessel – just 19 metres long with an 8-metre beam – the DOP’s compact, hydraulic-powered, design made it an extremely suitable choice.
Looking to make their dredging operations straightforward, Murjan Al-Sharq Marine Services also decided on a spud system.
By using the spuds, we do not need to use a complex, 4-point mooring system. These spuds are operational in water depths of up to 10 metres. In deeper waters, we will be able to extend the spuds.
In shallower waters, Mr Natheer points out the advantages of combining the Murjan 40’s 2-metre draught with the tried-and-tested performance of the DOP pump. “Shallow water dredging usually requires a lot of very sophisticated, expensive equipment. A solution such as this represents a cost-effective alternative.”
The complete package
Murjan Al-Sharq Marine Services started discussing various vessel options with Damen five years ago. “This continued when, three years ago, Mr Kommer Damen paid us a visit – something that meant a lot to us,” says Vice President Chris Clark.
And now, facilitated by Damen Customer Finance, we are pleased to have purchased our first Damen vessel. This is not just a versatile vessel, but with the DOP, we have taken delivery of a complete package.
The company intends to operate in areas where other vessels cannot. Murjan Al-Sharq Marine Services already has several contracts in place, adds Mr Clark. “One of the main types of services that we will be offering is clearing silt from oil. This is very specialist work and, because of the precision required in these jobs, this is what we call ‘surgical dredging’. The DOP in itself is also highly adaptable. With different suction heads, we can work in a variety of soils. What’s more, the versatility of the Multi Cat means that we can also use it for jobs such as transportation, towage, dive support, pollution control and anchor-handling.”
Using a different suction head for example, you can create new dredging tool for your next dredging project. Try our interactive configurator, which allows to choose the type of HDOP/EDOP with the capacity and suction head you require for your specific job. The result is a clear overview of the dimensions and requirements of the complete dredging tool, which enables you to determine the layout of your jobsite. Try configurator.
