OCEANKING SA exclusive representative of the NK Co., Ltd. in Greece & Cyprus is pleased to announce that the NK-O3 BWTS was listed in the USCG Under Review List!
The President of NK recently confirmed that NK Co., Ltd., working in cooperation with Lloyd’s Register and consultant Jad Mouawad, managed the NK-O3 BWTS to successfully complete all required USCG Tests, namely :
• Land -based Tests: 5 times Sea water test, 5 times Brackish water, 5 times Fresh water at Komeri IL Busan
• Shipboard Tests : 5 times in cooperation with Lloyds and Komeri
• Whole Effluent Toxicity & Disinfection Byproducts testing: 3 times
The shipboard test was conducted on board M/V Star Marisa, a 208K Bulk carrier, trading from Port of Qingdao (China) to Port Hedland (Australia). The vessel was in normal trading and has been ballasting and de-ballasting with the NK-O3 system on a regular basis.
The end of shipboard testing represents the conclusion of all necessary USCG testing requirements having completed besides the land –based testing, all the engineering design and the environmental testing elements of the submission.
The results, documentation and final drawings associated with the NK-O3 have been verified by IL and submitted to USCG for receiving the Type Approval.
The NK-O3 BWTS has been previously certified under the USCG Alternate Management System (AMS)
NK is the originator and patent holder of sea water disinfection using the side stream ozone injection. A very low quantity of ozone (2,5 ppm) is mixed with only 3% of the sea water entering the ballast lines and the mixture is injected again in the incoming ballast . No filter is required.
The system can be installed either in E/R , in Steering Gear or on deck and is ideal for retrofitting purposes as no modification of ballast lines is required .
