Norwegian traditions – a business with deep roots

TeamTec is continuing a tradition of marine industrial activity at Tangen in Tvedestrand, Norway, that dates

back to around 1700. Today our company is one of the world leaders in marine waste incinerating systems,

stripping ejectors and ballast water management systems for the maritime industry.

TeamTec is also responsible for sales and marketing of SeaSOx Scrubbers. TeamTec was founded on May

17th 1984, by a small group of enthusiastic pioneers. Their enthusiasm and passion is carried forward by

the entire TeamTec staff, and we are confident that our products will be in the forefront of international

development in the future.

We are proud to supply our quality products to a demanding maritime market.

IMS GROUP

TECHNOLOGYOceansaver® BWTS is based on the principle of filtration and disinfection by side stream electrodialysis. The system is designed and engineered for ship and crew safety. Electrodialysis technology ensures that hydrogen is generated separately and vented with a DNV GL approved extraction system.

SYSTEM OVERVIEW BALLASTINGBallast water is treated during uptake in the following sequence:

1. Ballast water is pumped through 40µm automatic self-cleaning filter.

2. Disinfectant is created onboard in a side stream electrodialysis C2E unit and injected through a treatment spool unit that mixes the disinfectant perfectly into the main ballast water line.

SYSTEM OVERVIEW DE-BALLASTING Ballast water is monitored during discharge in the following sequence:

1. A standby TRO (total residual oxidant) neutralisation unit ensures TRO levels are below IMO and USCG discharge limits at all times.

2. IMO and USCG discharge limits are in normal operation reached in approximately 24-36 hours and neutralisation is in most cases not necessary due to intelligent dosage during ballasting.
