Multipurpose marine SDS18 diving vessel-catamaran "Igor Ilyin" takes part in preparations of the route for "Nord Stream-2" gas pipeline

According to Interfax, multipurpose marine SDS18 diving vessel-catamaran "Igor Ilyin" takes part in preparations of the route for future gas pipeline "Nord-Stream-2".
46 m marine SDS18 diving vessel-catamaran "Igor Ilyin" was built at Navashino Oka Shipyard (is included in UCL Holding, Vladimir Kulikov is a general director).
The catamaran is built for FBE "Marine Salvage Service of RosMorRechFlot" (Andrey Khaustov is a head). The customer of the vessel was the State Transport Leasing Company.
The designer is the Marine Engineering Bureau.
Advisor of the general director of the SPA Special Materials Yuriy Klenov told to Interfax that destruction of naval ammunition of Great Patriotic War time, found on the route of the future Nord Stream-2 gas pipeline, is carried out with help of the innovative Aquaschit technology for the first time.
Works are provided by the SDS18 vessel-catamaran "Igor Ilyin", built by the Oka Shipyard in 2017.
Usage of the Aquaschit technology has provided reliable protection of the ichthyofauna from the high-explosive impact during destruction of explosive objects", Klenov said.
The search and destruction of the naval ammunition is being operated by undersea robot. "The newest technologies of underwater demining applied at the project "Nord Stream-2" provide maximum guarantees of quality and environmental safety" underlined Klenov.
He mentioned that the practical usage of the Aquaschit technology, developed by the SPA Special Materials and the Engineering and Technical Center for Special Works under the direction of Corresponding Member of the Russian Academy of Sciences, Sci.Dr., Professor Mikhail Silnikov, has a great future, as it provides minimum negative impact to the environment and avoidance of deth of marine life.
Project SDS18 of multipurpose marine diving vessel-catamaran "Igor Ilyin" has been named as the best innovative solution in the sphere of transport technology in the competition of innovative technologies among the transport firms "Motion Formula". The results of the competition were summed up on December 7, 2017 at the XI International Forum "Transport of Russia - 2017".
SDS18 vessel is intended for:
• providing of diving and underwater works on depth till 100 m and at sea state up to force 3;
• participation in rescue and ship-raising operations;
• placing and providing work of the research parties in accordance with installed technical means;
• inspection of a sea-bottom, sink objects, underwater part of ship's hull and waterside structure's;
• providing of remote operated deep-water vehicle using at sea state up to force 3.
SDS18 vessel is a single-deck steel double-hull catamaran with cross-structure, with deck-house and wheelhouse made of aluminum-magnesium alloy, with an elongated forecastle, with deck-house and wheelhouse located fore, with aft open cargo deck, with 2 full-turn rudder propellers and 2 bow thrusters, with engine rooms located in the side hulls of the catamaran. Navigation zone includes marine regions matching to R1 area. Radio equipment provide operation in areas A1, A2, A3.

Russian Maritime Registry of Shipping class notation is of KM Ice1 R1 AUT3-ICS OMBO DYNPOS-1 Catamaran Special purpose ship.
Two full-turn rudder propellers with fixed-pitch propellers in nozzles are installed aft in order to provide the required vessel's speed and steerability. Power transmission from main engines to rudder propellers is realized through cardan gear and elastic clutch.
Two bow thrusters of the "screw in a tube" type with a fixed-pitch propeller are foreseen for ensuring requirements of dynamical positioning DYNPOS-1, and also for improvement of steerability, during passing narrow waters and during mooring. Thruster capacity of is of 250 kW each.
The vessel's hull is strengthened by ice reinforcements for Ice 1 class.
Cargo hydraulic crane-manipulator is foreseen; its capacity is pf 1 t at boom outreach 25 m.
Container sockets and eyebolts are installed on the main deck for TEU securing; a set of twist-locks is foreseen in the vessel's supply.
A 6-men rescue boat is located on the bridge deck, lifting and lowering of the boat is done by the davit. There also working boat for auxiliary operations.
The vessel is equipped with two high-holding power anchors located fore.
Crew consists of 7 people, total places onboard are 12.
Arrangement of special staff (18 people) is provided.
Each crew member is placed in a single cabin with lavatory and shower; five cabins are equipped with additional folding beds. Nine double cabins with lavatory and shower are intended for special staff arrangement.
Living and office compartments are arranged in the fore deckhouse and forecastle.
Two laboratories are required foreseen for providing and providing work of the research party.
The wheel house has all-round looking and provides single-man vessel's control.
A diving complex is provided to perform diving operations using compressed air for depths up to 60 m; a mobile version (2 TEU) is foreseen. There are diving ladder for divers coming under water.
2.5 x 2.5 m trunk is placed on the main deck in the middle; the trunk has hydraulic closing.
Keel of the SDS18 lead vessel "Igor Ilyin" (building No. 2300) was laid down on 01.12.2016. She was launched on 26.07.2017 and put into operation on 12.10.2017.
