The first two ships in series were equipped with foreign-made cranes. In the latter case, the matter is the low-magnetic (titanium) version of HTFC-2.2T10M-A-LM hydraulic telescopic-boom crane.
Among other missions, the device is designed for lifting of an unmanned distant-controlled boat. According to the specifications, the crane’s capacity is at least 2.2 tons, max handling radius from the stand axis is 9 meters. Materials of the crane’s components should be made of low-magnetic alloys like aluminum or titanic ones.
On May 31, 2016, Sredne-Nevsky shipyard announced the request for proposals regarding supplies of such cranes. The trigger price was 82 mln rubles. Four companies submitted bids then. On August 19, Sredne-Nevsky shipyard posted a notice of refusal from procurement.
On April 17, 2018, the yard tied a contract with the Singapore company named Titan Offshore Equipment Pte Ltd for supervision and adjustment works and participation in mooring trials and revision stage of HTFC-2.2T10M-A-LM cranes. Cost of works is 126,300 SGD, which is about 6 mln rubles.
An informed insider told Mil.Press Today that Sredne-Nevsky shipyard had been tasked to prepare information about delivery terms and purchase procedures for other three minesweepers.
Project 12700 Alexandrite-class composite minesweepers were designed by Almaz bureau as the new-generation mine countermeasure ships. They are equipped with sonars mounted both onboard and on remotely controlled and standalone underwater vehicles; however, the ships can use traditional sweep armament as well. In addition, Alexandrite-class minesweepers operate the unmanned motorboats.
