The floating crane Grigory Prosyankin is to obtain the transparencies made by ORPE Technologiya

6 May 2020
ORPE Technologiya named after A.G. Romashin produced the high-strength transparencies for the floating crane PK-700 Grigory Prosyankin. The electrically heated structural optics products are to provide a qualitative overview to the crew and the ability of equipment operation in different climatic conditions.

The electrically heated triplexes are made of silicate material and fully conform to the stated technical specification requirements such as humidity, temperature stability in the range of -40ºC to +55ºC and high strength. The complete set includes eight structural optics products designed to equip the floating crane wheelhouse. Technical characteristics of transparencies manufactured in partnership with Krasnoyarsk casting-extrusion plant Segal are to ensure the reliability of PK-700 operation in both tropical and boreal marine climate.

“We have great experience in manufacture of transparencies from various materials for water equipment. The structural optics products by our enterprise have been used on nuclear icebreaker Rossiya, bathyscaphes Mir and even cruiser Avrora. Currently, we are completing the manufacture of transparencies for another floating crane wheelhouse having lifting capacity of 400 tons, the customer of which is also Segal plant. Besides, the active work is carried out on the development of lighter and stronger organic materials structural optics products. Several hydrofoil passenger sea craft Kometa 120 M are already equipped with this type of transparencies”, said Andrei Silkin, Director General of ORPE Technologiya.

The construction of the heavy floating crane Grigory Prosyankin began at the Sevastopol Marine Plant (part of the United Shipbuilding Corporation) on November 2018. The floating crane is named after the outstanding shipbuilding engineer Grigory Prosyankin, Hero of Socialist Labor, one of the creators of the USSR Nuclear Navy, Director of the largest enterprises of the shipbuilding industry Sevmash and Zvyozdochka. The delivery of PK-700 Grigory Prosyankin to the customer is scheduled on December 2020. After commissioning, the floating crane will be involved in the construction of nuclear submarines as well as the maintenance of major surface craft at Sevmash.
