Which ballast water treatment system is best for my vessel?
Selecting a ballast water treatment system can be complicated. There are many systems in the market with different treatment techniques. The operational profile and trade routes of a vessel can result in it having to comply with BW regulations set by both the USA via the Vessel General Permit (VGP) and the IMO with its BWMC 2004. More complex choices also need to be made regarding which technology is best suited for a particular vessel.
To help in making the choice, Damen has identified preferred suppliers who offer high quality BWT systems that are effective at low temperatures, in all salinities and with low UVT. Owners can select the model that best fits their requirements and ensures that they are fully compliant with all relevant BW regulations.
Damen’s focus on standardisation makes the BWTS installation process easy, cost-efficient and ensures that each system is fully operational and compliant on departure.
What determines the necessary capacity?
The necessary capacity is determined by the existing onboard ballast system and operational scope of the vessel.
Damen offers systems from preferred suppliers with ballast water treatment rates of 60 m3/hr up to 10,000m3/h.
Is there a sufficient space to install a ballast water treatment system?
Ballast water treatment systems come in different configurations; from separate, interconnected components installed in different locations within a vessel, through skid mounted systems to others that are containerised. To determine which configuration suits your vessel best, an installation survey is offered (with a 3D scan) which results in useful and practical advice based on Damen’s 85 years’ shipbuilding experience.
Which technology is best suited for my operations?
In partnership with our trusted partners, Damen offers two different technologies that provide total BWT solutions:/p>
I. Onboard treatment systems with continuous filtration, automatic backwash and UV-sterilisation (Bio Sea, Trojan Marinex);
II. Onboard treatment systems with continuous filtration, automatic backwash and electro-chlorination (Evoqua).
What factors need to be taken into account when choosing and installing a BWTS?
Installing a BWTS is not simple and many factors have to be taken into account. These include:
Engine room space
Available electrical power
Ballast pumps capacities and min/max rates
Health and safety
Integration with existing systems
Crew workload and training
Capex and Opex
System selection, availability, delivery and installation time
Damen currently works with three BWTS manufacturers, what does this alliance mean for shipowners?
There is a need to coordinate and ensure cost effective implementation and life cycle support. With the large number of vessels to be retrofitted, in the years ahead logistics will become complicated and challenging. There will be subsequent supply problems for BWT equipment, engineering and class in a booming market.
By working with the selected BWM partners Damen is able to offer a complete, cost effective package in a coordinated, timely way. We need to ensure that every installation is done right first time as the vessels need to be compliant when they leave the dock. This can only be done in close partnerships and by standardising and specialising as much as possible. Moreover at Damen we leverage our buying power to the advantage also of those ship owners operating only a few vessels. With our current partners we can service a very broad range of vessel types and customers.
Does Damen offer servicing of equipment, as well as installation?
Yes, we do. We have set up a complete though-life, one-stop-shop approach. We offer a cost effective total BWT solution; covering system selection, survey & 3D scanning, engineering, procurement, installation, commissioning and training. And our services do not stop after installation. We can also provide training, system maintenance and delivery of spare parts for retrofitted BWT systems.
Does Damen offer Retrofit Solutions at all the shipyards in the Group, whatever their size?
Our one stop retrofit offering is targeted at all vessel types that need to comply with BWM regulations. Installation of a BWTS can be done at any of the Damen Shiprepair & Conversion shipyards, which are conveniently located worldwide. Systems can also be installed at a customer selected non-Damen yard, or even during operations.
Is Damen also marketing newbuild installations with its partners?
Damen’s main focus is on providing a global total retrofit solution. But we can also sell our partner’s systems to newbuild projects.
