2020 Highlights

CNIM becomes the exclusive supplier of Milrem Robotics ground robots in France.
As a system integrator for the French Army, CNIM provides Milrem Robotics' robots for unarmed interventions (logistic transport, surveillance, mine clearance, route opening or reconnaissance operations).

The manufacturing of the first two EDA-S is starting,
following the contract for the renewal of the landing craft of the French Navy won by CNIM and its partners SOCARENAM, MAURIC and CNN MCO.

The Chinese Ministry of Health acquires 16 Sterilwave banalization stations from Bertin Technologies.
Sterilwave enables the treatment of infectious risk hospital waste potentially contaminated by the coronavirus within Wuhan hospitals and eliminates the risk of contamination outside the hospital.

CNIM is launching the construction of a new 2,500 m² building on its La Seyne-sur-Mer site,
thus completing its equipment for the manufacture of large and precision parts for the semiconductor, large scientific instruments, nuclear and aerospace industries.

The lifting beams designed and manufactured by CNIM for ITER Org will be used to position the 1250t of the ITER cryostat base. 3 m high and 10 m long, weighing 11 tonnes each, the spreaders are coupled together by a hydraulic compensation system allowing the load to be distributed over all 4 spreaders.

CNIM's handling system balanced the 1250 tonne base of the ITER cryostat during its installation in its final location.
This installation marks the beginning of the assembly of the machine, which is capable of generating a 150 million degree plasma to create the fusion reaction.

CNIM Air Space has carried out a 24/7 aerial surveillance experiment with the Gendarmerie Nationale,
at the Centre National d'Entraînement des Forces de Gendarmerie in Saint Astier. A White Hawk tethered airship, equipped with an EO/IR optronic ball, was integrated into the training exercises of the Gendarmerie Tactical Groups (GTG).

Bertin Technologies, C4Diagnostics and Enalees launch BEC-SARS-CoV-2, an ultra-fast and sensitive detection kit for Covid-19.
The aim is to create tests that can detect the SARS-CoV-2 virus in situ, in less than 15 minutes and with high sensitivity. A first version tests the ambient environment. The next version, currently under development, will target people.

CNIM delivers 6 Pre-Compression Rings (PCRs), composite rings of more than 5 metres in diameter, to F4E.
This is the first shipment of PCRs delivered to the ITER reactor site in Cadarache.

The British Safety Council awards Sword of Honour to CNIM Environnement & Energie EPC for health and safety management at Sharjah site.

As part of an R&D partnership contract with RTE (Réseau de Transport d'Electricité), CNIM Air Space has developed a customised airship drone demonstrator: Diridrone. It is aimed at infrastructure inspection and surveillance professionals looking for an innovative, persistent aerial platform with reduced operational costs.

The flue gas treatment of EEW's new waste-to-energy plant in Stapelfeld, Schleswig-Holstein (Germany), has been awarded to LAB.
The plant will be equipped with a highly efficient LAB flue gas treatment system and designed for low emission levels.

CNIM delivers to TechnicAtome the 18 parts that comprise the core of the Jules Horowitz Reactor (RJH) run by the CEA Cadarache and intended for the safety qualification of nuclear materials and fuels subject to radiation. CNIM has mobilized its various areas of expertise in TIG and MIG welding, electron beam welding and large-scale machining with a high level of precision.
