Rosatom’s Mobile Laser Complex (MLC) has been used for the first time to dismantle a tall metal structure. Specialists of Rosatom’s scientific division used the laser complex cut the supports of two cranes up to 40 metres high and with a carrying capacity of up to 32 tonnes. The work was done for the Reforma Group of Construction Companies.
“Our complex provides operational special technological work and can be used to solve a wide range of tasks, such as remote separation laser cutting, underwater gas laser cutting, as well as to eliminate the consequences of technological accidents, for example, spill of petroleum products,” said Kirill Ilyin, Director of JSC Science & Innovation “It is important that this time the use of the remote separation laser cutting method made it possible to carry out dismantling with ‘jewellery precision’ in compliance with all industrial safety requirements. The container with MLC and the personnel were at a distance of up to 100 metres from the object.”
The mobile laser complex developed by the Troitsk Institute of Innovative & Thermonuclear Research (Triniti) makes it possible to perform work on remotely cutting metal structures up to 300 mm thick using laser radiation from a distance of up to 200 metres. The complex was commissioned in 2020.
The MLC uses serial fibre itterbium lasers and is designed to perform remote laser cutting, to eliminate oil spills, underwater gas laser cutting, fragmentation of equipment at hazardous facilities, and destruction of ice formations. The complex is assembled in a container in which equipment and places for two operators are located.
In 2023 MLC was used to dispose of sunken ships on Sakhalin (specialists cut the hull of a vessel located near the pier at depths of up to 4 metres). It also passed tests to eliminate accidental spills of oil products – using laser radiation, specialists set fire to a combustible mixture from a distance of about 300 metres.
