Provision of a deployment system for the cores of the Atalante N / O.
The current launching system of the Atalante corer is worn out and is no longer suitable from a safety point of view. A new system must be designed to receive and handle a Calypso type corer and a Küllenberg type corer.
The work required consists of designing 4 identical beams as well as a maneuvering platform. Each of these beams must be equipped with an electric winch (tilting operation of the corer) and an electric jack (over-run of the corer). The synchronization of each of these operations is to be performed by an industrial automaton controlled from wired and / or wireless remote controls. The platform constitutes both the point of rotation of the tilting operation and the resumption of the gravity forces of the weight (of the counterweight) of the corer.
Supply, installation, commissioning of a strong vibration power installation and the associated maintenance (optional).
The CEA CESTA considering the acquisition of a new test facility: a generator of electrodynamic vibration high power and associated test tools.
The facility will be capable of generating vibrations of a force of 250 kN in a frequency range of 5 to 3000 Hz.
The entire service will include the supply and implementation on site an electrodynamic vibrator and associated easements, two side tables and mechanical adaptations for the implementation of the whole.
This test medium will blend in a thermomechanical complex comprising a plurality of testing means with a remote control of the set of installed elements.
The benefit is to deliver consistent set of Vignola Steel rails to be installed in an ultra clean environment (ISO Class 7).
This contract aims to restore compliance a set of flat bottom rails in steel to be installed in an ultra clean environment (ISO class 7).
The set consists of 160 curved rail section 108 mm x 108 mm, variable length from 2.5 to 4.5 meters, and mass 75-130 kg / piece. A complementary set, consisting of rails and samples followers will realize (bending, machining, ...) and process according to the compliance process.
The rails of compliance is to carry out marking, sandblasting, surface treatment by ion nitriding, cryogenic cleaning, setting ultra-cleanliness, specific packaging and packing. These operations will be conducted in batches of successive rails. Representative samples are followers to achieve.
The market is flat, the Bidder will ensure the implementation and operational monitoring. Managing outsourcing and logistics and schedule aspects are strong constraints.

Supply, installation, commissioning of a high power vibration installation as well as associated maintenance (optional).
CEA CESTA is considering the acquisition of a new test facility: a high power electrodynamic type vibration generator and associated test tools.
The installation will be able to generate vibrations with a force of about 250 kN in a frequency range of 5 to 3000 Hz.
The entire service will include the supply and installation on site of an electrodynamic vibrator and associated easements, 2 auxiliary tables and mechanical adaptations for the implementation of the set.
This test means will be integrated in a thermomechanical complex comprising several test means with a remote control of all the elements installed.
