Namdock drives ballast water treatment niche

By Business Reporter

NAMDOCK, an established ship repair company strategically located on the west coast of Africa in Walvis Bay, Namibia, is leading the industry with the provision of a ballast water treatment system installation service.

This ensures that offshore support and other vessels docking for repairs by Namdock are also able to comply with the International Maritime Organisation’s (IMO) requirements for ballast water management and treatment.

This is according to Claus Zeilinger, Assistant Technical Superintendent of Carpentry and Electrical at Namdock.

“We have led the ship repair market on the West coast of Africa in the installation of ballast water treatment systems since last year, when we obtained certification to install Bio Sea ballast water treatment systems on board our clients’ vessels,” Zeilinger advises.

Namdock has since successfully installed two of these systems on one of its long-term clients’ offshore support vessels.

“We have also recently completed the complex installation of an ESMA ballast water treatment system in a heavy fuel tanker which docked in Walvis Bay. This was a major and very interesting project, which saw an inter-disciplinary team of fifty people working around the clock to pull off the project. This was successfully completed in just three weeks,” he adds.

The installation of ballast water treatment systems is part of Namdock’s integrated ship repair offering: “We perform the full spectrum of ship repairs, from metal work and fabrication – which involves physical plate installations – to piping and electrical installation. Our integrated vessel repair disciplines, capabilities and functions therefore go hand-in-hand with the installation of ballast water treatment systems,” Zeilinger explains.

At this stage, Namdock undertakes work on the piping, valves and electrical installation of the ballast water treatment system. Their certified installation team commissions the system, and then trains the client’s staff on board the vessel in the operation thereof.

Zeilinger explains that Namdock installs systems which have been certified for ballast water treatment on vessels in port by the IMO: “Our task is to determine the best possible position for the system on the vessel in question, and ensure that it operates as it is intended to.”

Zeilinger and two of his team members completed training in the installation and commissioning of the Bio Sea system in France last year.

“One of the main benefits of this system is that it treats the ballast water through ultra-violet (UV) radiation. It is therefore completely safe to use, contains no harmful chemicals and the installation is simple. These factors make it one of the best systems to use worldwide,” he enthuses.

Namdock has presented its recently-completed ballast water treatment system installations to maritime class surveyors, who verified that they were satisfied with the way in which the systems were operating. The installations were done on vessels which had docked at Port of Walvis Bay for their two or five year classification surveys.

Zeilinger explains that ballasting is the process whereby seawater is pumped into the vessel to balance and submerge it deeper into the water, in order to have a more comfortable and stable sail. Seawater in different oceans differs in salinity, as well as in the concentration thereof, and in the species of bacteria and other marine micro-organisms present. Ballast water therefore needs to be treated to destroy any bacteria, viruses and micro-organisms it contains – to prevent the pollution of seawater and marine ecosystem accordingly.

Namdock’s services relating to ballast water treatment systems will also benefit the local Namibian maritime environment, as the ballast water deposited by vessels docking at the port will not contain foreign viruses or bacteria which could harm the country’s beautiful beaches and coastline.
