46 SUSTAINABILITY SPECIAL 47
Damen launched the InvaSave 300 back in 2017 in preparation
for the Ballast Water Convention coming into force the same year.
The IMO-certified system is an external ballast water treatment
unit designed primarily for use in ports and harbours. InvaSave
treats ballast water in a single pass using mechanical filtration and
ultraviolet radiation to remove and eradicate invasive organisms,
to IMO-D2 standards, from inbound vessels. It can provide ballast
water of the same quality to outbound vessels.
Demonstrating the potential InvaSave has, Damen was recently
asked to assist a vessel that had experienced a failure of its on
board ballast water treatment systems.

have imagined, for example, that a port-based treatment system
could serve the offshore industry?” Asks Damen Green’s Philip

need ballast water exchange only very infrequently. Nonetheless,
they are required to comply with the regulations. Invasave provides
a solution without the need for costly conversion – and without

SHOWING SUITABILITY WITH SERVICE
In order to demonstrate the effectiveness of the system Damen has
developed the InvaSave Service. Philip explains:
“With the InvaSave Service, we don’t only supply the InvaSave
equipment for customers to treat ballast water, we come to you,
operating the system ourselves, to actually treat ballast water
in a certified and compliant manner. It’s part of Damen’s goal to
go beyond merely supplying products and to be an innovative
maritime solutions provider.

“We recognise that InvaSave is an innovative concept and that,
despite proving its effectiveness via certification and awards,
operators may like to see its results first-hand before committing
to its use. Therefore have taken it upon ourselves to prove the
product!”

BALLAST WATER TREATMENT ON TOUR
Damen initially launched the service back in 2017 and now things
are in full swing. The company has built four InvaSave units and has
successfully operated them in north European ports.
“We have now conducted several projects, in different ports, for
clients who would otherwise have been stuck with no ballast water
management solution available. The InvaSave Service clearly
demonstrates the validity of the InvaSave business case.”
In order to further develop the InvaSave network, Damen is also
participating in projects with other partners.

“For example, we are part of the EC-funded INTERREG Europe
Blue Port Services project. This initiative aims at bringing together
maritime stakeholders from throughout Europe to cooperate on
issues relating to the management of ships’ effluents – including
ballast water.

“With this we are performing demonstrations of the InvaSave in
various ports. We are demonstrating what the system can do
