• 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 two full-turn rudder propellers and two bow thrusters, with engine rooms located in the side hulls of the catamaran.

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.

Living and office compartments are arranged in the fore deckhouse and forecastle.
Two laboratories are foreseen for 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.
