DAMEN YOUR TRUSTED PARTNER

FOR BALLAST WATER COMPLIANCE

OUR PLANNING - YOUR COMPLIANCE

Damen Green Solutions is member of the Damen Shipyards Group (1927), an international shipbuilding, repair and conversion group with more than 9,000 employees working at 32 yards worldwide. Since 1969 Damen has built over 5,000 vessels and annually delivers around 160 vessels across a wide range of types and capabilities.

For nearly all vessel types Damen offers a broad range of services, including maintenance, spare parts delivery, training and the transfer of (shipbuilding) know-how. Damen also offers a variety of marine components, such as nozzles, rudders, anchors, anchor chains and steel works.

In addition to ship design and shipbuilding, Damen Shiprepair & Conversion (DSC) has a worldwide network of 15 repair and conversion yards with dry docks ranging up to 420 x 80 metres. Conversion projects range from adapting vessels to today’s requirements and regulations to the complete conversion of large offshore structures. DSC completes around 1,500 repair and maintenance jobs annually.

Taking the lead in cost-effective solutions for ballast water management

Damen recognised the need to start addressing the ballast water management challenge several years ago when it began investing in the development of ballast water treatment products and solutions. This led to the establishment of a new company Damen Green Solutions B.V. located next to Damen’s headquarters in Gorinchem, the Netherlands. The priorities of Damen Green Solutions were to:

• Evaluate the solutions available in the market
• Establish partnerships with the leading manufacturers
• Create retrofit service packages that cover every aspect of the design, installation and compliance process
• Design a mobile in-port ballast water treatment unit
• Make the systems and services available throughout Damen’s global network

With at least 60,000 vessels needing to comply with international ballast water treatment legislation in the near future, Damen Green Solutions now offers a range of cost-effective options for ship owners from one stop retrofitting to a pioneering mobile ballast water treatment unit, which is the first of its kind in the world.

BALLAST WATER TREATMENT

More than 90 per cent of global trade is carried by sea, and each year transfers of up to 12 billion tonnes of ballast water take place around the world. Ballast water is used to maintain the stability and trim of vessels, and to ensure their structural integrity. It is typically pumped in as the cargo is unloaded and discharged as the cargo is being placed on board.

Ballast water that is taken on in one ecological zone and discharged into another can introduce invasive and nuisance aquatic organisms that may have detrimental impacts on the local biodiversity, economy or even the human health of communities in the surrounding areas.

Bio invasion is one of the four greatest threats facing the world’s oceans today, alongside land-based sources of marine pollution, the over exploitation of living marine resources and the physical alteration and destruction of marine habitats.

The proper treatment of ballast water, as required by the IMO and the USA authorities, actively removes, kills and/or neutralises organisms prior to discharge. Ballast water treatment differs from the older conventional process of ballast water exchange, which involved completely flushing the ballast water tanks while underway.

BALLAST WATER TREATMENT REGULATIONS

The USA began enforcing its ballast water regulations (US Coastguard) in June 2012, and the IMO’s Ballast Water Management Convention is expected to come into force in the very near future. In addition other national bodies introduced regulations in response to national concerns.

When the IMO Convention is finally ratified, all ships trading in international waters will be required to manage their ballast water on every voyage by either exchanging or treating it using a type approved ballast water treatment system. In accordance with the implementation dates relative to vessels’ ballast capacity, treatment will be mandatory after a ship’s first IOPP renewal survey once the IMO BWMC enters into force.

Under the IMO regulations, this means that some 60,000 vessels are going to need ballast water treatment solutions in the short-term. Most of these vessels are expected to comply by installing a fixed ballast water treatment system on board.

IMO Ballast Water Management Convention

The IMO adopted the Ballast Water Management Convention in February 2004. The convention will enter into force 12 months after ratification by thirty nations that together represent 35% or more of the world’s total merchant shipping tonnage.

The convention Requires That ballast water must be treated - to specify D2 standards - before it is Discharged. All vessels built before entry into force of the BWMC, must install a Type Approved system at the first renewal of the IOPP certificate.

Vessels sailing in U.S. waters will be required to comply with USCG ballast water discharge standards and the USEPA Vessel General Permit (VGP), in addition to State ballast water regulations.

The USCG’s final rule is a ballast water discharge standard which is the same as that adopted by the IMO in 2004. In addition, the USEPA 2013 Vessel General Permit has adopted numeric limits within the permit that also align with the USCG rule.
