10/18/2017: Marine Safety Center issues amended Ballast Water Management System Type Approval Certificate to TeamTec AS

The Marine Safety Center has issued an updated type approval certificate to TeamTec OceanSaver AS for the OceanSaver BWTS MKII Ballast Water Management System.

The updated certificate was issued as a result of the acquisition of all OceanSaver intellectual property, certificates and assets by IMS Group AS. TeamTec OceanSaver is a member of, and fully owned by, IMS group AS. A copy of the type approval certificate may be obtained by contacting the manufacturer.

All OceanSaver equipment manufactured during the validity of the original type approval certificate remains approved as long as it is manufactured, installed, and operated according to the terms of the type approval certificate. Any maintenance and repairs to this equipment must also be performed in accordance with the manuals and components specified as part of the type approval. If the equipment fails to operate and parts from the original equipment manufacturer are no longer available, then the equipment is no longer operating under its type approval and must be replaced.
