In period from January till February 2019 dock repair of dredger hopper (floating excavator) MP-26 was carried out: repair of hull, blasting and painting.
Complementary to dock works the Yard carried out repair of spuds. The work described above is rather complicated as spuds have got considerable dimensions and weight herewith they must be of precise dimensions with the smallest possible deviations. The length of spud is almost 32 m (as high as 9-store building), and the weight is 52 ton.
During spud repair the high strength steel was used that is not typical for ship repair - 30 mm thick. Engineers of our technical department have developed the repair procedure, and the welding department has calculated welding conditions with account of strains and deformations making allowance for real conditions and environment.
Welding has been carried out precisely in accordance with procedure using imported flux-cored wire in Ar+CO2.
All works were carried out under Customer's technical supervision and QD permanent monitoring using modern measuring equipment.
Works were carried out to the highest standard and in due time.
