The Blue Impact

Mechanical dispersion is the process
of using water jets to pulverize oil
into microscopic droplets - without using
chemicals. The oil will stay suspended
and be efficiently degraded
by natural occurring bacteria.

During the first half of 2018 we have developed and
built an Unmanned Surface Vessel (USV) for
chemical-free dispersion of oil spills.
The USV will go through a substantial testing
program this year. Sign up to follow our development

About us

Over the last 6-7 years Blue Impact and partners have performed several laboratory tests and technology development projects to establish an operational solution for mechanical dispersion of oil spills at sea. The development is based upon patents held by Stein Erik Sørstrøm, a former senior scientist, research director and senior business developer at SINTEF, together with other experts at SINTEF.

SINTEF TTO initiated a commercialisation process, and Blue Impact AS (formerly Chemfree AS) was formed in 2016 with a team consisting of Stein Erik Sørstrøm and Karl Fjelde Nevland.

One main objective of our development is to improve the way we handle oil spills at sea.

Technical information about Vorax - our USV for dispersion of oil spills without chemicals. Vorax means "I break down" in latin, and we’ve named the USV after Alcanivorax, which is one of the main bacteria breaking down oil spills.
