With the opening of navigation, VIKAR completed the project of transporting heavy equipment from the temporary pier on the Neva River of PJSC Izhorskie Zavody to the Big Sea Port of St. Petersburg, the pier of the Baltic Shipyard. Before the start of transportation, the specialists of LLC VIKAR carried out a thorough study of the project and action plan for the delivery of one propeller motor weighing 276.16 tons with overall parameters of 8955 x 5605 x 4500 mm. The rowing motor is designed for the latest generation icebreaker, manufactured at the Leningrad Electric Machine Building Plant.

For the transportation of heavy cargo, our company made a diving survey of the bottom, depth measurements, cleaning of man-made objects and a sand cushion at the temporary pier of Izhorsk Plants PJSC. Towage was submitted to the towing – barge structure of the corresponding carrying capacity and weather conditions. When setting the barge to the pier, an additional tug was used. Performed the necessary ballast operations. Oversized equipment was loaded using ro-ro on a temporary pier in the Ust-Izhora region. Specialists of our company completed the loading and fastening of expensive equipment on the barge platform in accordance with the CTG transportation project on a barge that was specially developed and agreed for this transportation.

The rowing motor was placed on a specially designed foundation, installed on wooden pads on the cargo deck of the barge, so that, without additional reinforcing measures, the hull of the barge would distribute the loads on the deck structures. For fastening, a combined fastening system was used: steel stops from transverse and longitudinal displacement of foundations and chain lashings with a tension device to prevent lateral displacement and tilting of the propeller motor. For fastening the lashings on the cargo deck, the eyes were welded in the appropriate places.

Upon the arrival of heavy oversized cargo to the destination, the equipment was cleared and unloaded using a Demag SPK-1 crane, with a payload of 350 tons to the shore.
