For construction company BAM, the DTS Waterfront Brigade,
in collaboration with De Boer & De Groot, has performed maintenance
at the quayside of the Wilhelminahaven. This part of the Dutch seaport
“Eemshaven” is mainly used for supplying and discharging raw materials
for the power plants such as coal and biomass, gypsum, fly ash and
components for offshore wind farms. The Wilhelmina quay consists
of two long sides and a short one and is a total of 1,250 meters long
and 12,5 meters deep.
The cooperation between all the parties involved during this major
maintenance project was very good. The proper safety protocols –
which were of great importance due to all the port traffic – were observed.
Communication with Groningen Seaports was also excellent.
Important point of attention were the fenders. These are steel guiding
structures on the quay walls with polyethylene (UHMW-PE) guides,
which serve as protection of the quays in the mooring of large ships.
Thorough and regular maintenance of the fenders is therefore necessary.
The fenders were secured with m47 (!) size bolts. The divers of DTS had
to place them under water and tighten them with a large air wrench.
In addition, dilatations were repaired with Sealtaq Aquablock and
Sealtaq Repair Filler – a viscoelastic material that is water resistant
and air, water and gas tight and also 100% environmentally friendly.
The material protects both wood and concrete structures against corrosion,
so the effects of the repairs are lasting for many years to come!
The application of these materials is only done by Sealtaq certified applicators.
They obtain their certificate after an exam with Stopaq – the manufacturer,
based in Stadskanaal. Within the DTS Waterfront Brigade, all applicators
are well trained to work with the right materials. And if we need any
recommendations about various applications, we can always count on
the support of the SEAL FOR LIFE Service Application Team, who provide
DTS Waterfront Brigade with all the right application manuals.
