Wilhelmsen Ships Service prepared for changes in IMO approval criteria for tank-cleaning chemicals

Aug. 19, 2010 - The IMO has changed the approval criteria for tank-cleaning chemicals, with no perfume or colouring agents now allowed in tank-cleaning chemicals that will be discharged to sea inside the shore limits as listed in the MARPOL 73/78 ANNEX II. All tank-cleaning products approved to MEPC./Circ.363 prior to 1 January 2007 now have to be re-evaluated based on the criteria outlined in MEPC1/Circ. 590. All IMO approved products evaluated through MEPC./Circ.363 before 1 January 2007 ceased to be valid on 1 August 2010 when the new and revised regulation MEPC 2 /Circ.15 came into force.

With its long experience in this area, Wilhelmsen Ships Service understands that tank cleaning is a vital factor governing the success of ships' operations. Ship owners and traders also recognize the importance of efficient tank cleaning products and procedures to improve ship management efficiency, reduce operational costs and promote safety at sea.

Wilhelmsen Ships Service with its Unitor Chemical tank cleaning product range is pleased to announce that it is in full compliance with paragraph 13.5.2 of Annex II of MARPOL 73/78 and all of its products are listed accordingly in MEPC 2 / Circ.15 annex 10. All Unitor Chemical tank cleaning products can be used as outlined in these documents.

Wilhelmsen Ships Service has accumulated extensive knowledge over many decades through being confronted daily with a variety of problems associated with tank cleaning. Access to this vast experience can be made available to owners and operators by contacting the trained professionals found throughout the Wilhelmsen Ships Service global network.
