The development of the Close Circuit Cavitation Technology  (C3T) was instrumental in the establishment of OceanSaver AS. MetaFil/ Mentum was contracted to develop the technology by OceanSaver already in 2004. The recent agreement provide Mentum with the freedom to develop the technology further for applications outside that of Ballast Water Management. Applied Cavitation is a prioritised business area for Mentum.

ILO promotes social justice and internationally recognized human and labour rights. The organization have addressed concerns with regards to established practices related to Shipbreaking as undertaken in countries such as Bangladesh, India and Pakistan. A summary of their involvement can be found at http://www.ilo.org/public/english/dialogue/sector/papers/shpbreak/.

The International Convention for the Safe and Environmentally Sound Recycling of Ships, adopted in May 2009 developed by the International Maritime Organization (IMO) will enter into force only after 15 States representing 40 per cent of world merchant shipping by gross tonnage have ratified it. Furthermore, the combined maximum annual ship recycling volume of those States must, during the preceding 10 years, constitute not less than 3 per cent of their combined merchant shipping tonnage….

There are concerns as to the lack of mechanisms that could address both social as well as environmental issues in the intermediate period until the Convention and its Regulations enters into force – witch may last for quite some time. The ILO has decided to undertake a scoping study with the aim to identify initiatives or incentives to promote actions to improve in particular workers safety during the shipbreaking process in this period.

It will enter into force 24 months after the date on which new  and have over quite some time been promoting the last decade actively involved itself in the conditions under which ships are

NOFO – the oil spill preparedness and contingency operator on the Norwegian continental shelf have asked Mentum to take part in a think-tank process to address issues related improving oil spill operations in heavy weather.

A first session was held at the Norwegian Coastal Administrations preparedness centre in Horten on September 28 – 29.

The process aim to establish development projects materialising in new improved methods and/ or equipment for heavy weather oil spill operations.

Mentum have received a grant from Innovation Norway to support the further development of Mentum’s Close Circuit Cavitation (C3T) concept. The C3T technology applies controlled and targeted hydrodynamic cavitation for purposes such as treatment (e.g. disinfection, changing chemical characteristics, etc.), mixing (e.g. blended fuels, to improve a products shelf life, etc.), sizing (e.g. grinding, nano-sizing, etc.) and flow improvement (e.g. reducing drag along passing surfaces.).

Currently the C3T technology is applied in the OceanSaver Ballast Water Management System where it applies a cavitation field releasing pressure peaks ranging up to above 1000 bar at a frequency of 100 kHz. The fund will help Mentum identify other market areas for the C3T technology.
