The first in the world, to offer a full range of services to test ballast water treatment systems to meet IMO specifications:



Small scale, pilot scale and laboratory testing for system evaluation and development, basic approval, applications and verification of performance prior to full-scale testing

Pilot or laboratory scale testing carried out according to clients needs and requirements



Full scale land-based testing of treatment technologies in accordance with IMO guidelines (G8/G9)

Full scale land testing can be carried out in the course of a period of 2-3 months. Processing and reporting are completed within the following 1-2 months



Shipboard testing of treatment technologies in accordance with IMO guidelines

Shipboard test design by mutual agreement. Typically BTN is consulted at an early stage to advise on important logistical and technical issues that are essential for easy and successfull shipboard testing


We have a strong team to ensure success

The testing of treatment technologies for ballast water is conducted by a highly qualified staff
with extensive expertise ensuring the highest quality results, professional integrity and confidentiality.

We have 5 years of experience with R&D and procedures for testing treatment technologies for ballast water, and are world leaders in having completed full scale land based testing for 11 different vendors and shipboard testing for 5 vendor.

We have experience in running all required tests as proven by the PureBallast certification. We have Comprehensive Quality Management Plan (QMP) and Quality Assurance Project Plan (QAPP) conforming to IMO requirements.

We work in a close cooperation with certification agencies and regulators, have all the necessary facilities and equipment in order to conduct all required tests (infrastructure, certified chemical laboratories, biological analysis, and ecotoxicological analysis).


Laboratory facilities in Oslo and test facility at Solbergstrand include:

  • Large-scale growing capacity for added organisms (bacteria, algae and zooplankton), a harvesting system for naturally occurring algae and zooplankton
  • Access to accredited analytical services in chemistry and biology, and test systems for eco-toxicological tests
  • Comprehensive generic project plan (PP) and Quality Assurance plan (QAPP) conforming to IMO requirements
  • Freshwater, brackish and seawater available, by using groundwater, seawater intakes from different depths
  • Flexible system for pumping water in ballasting and deballasting operations during pilot and full scale tests. Challenge water is made with chemical and biological additives in any volume up to 550 m3 in a supply tank, with test water and control water removed in series from this tank
  • Excellent capability for developing testing the technology on a small scale, prior to full-scale testing
