Oka Shipyard laid down the keels of two RST38 project bilge water collector vessels for Rosmorport
  
On December 23, 2021 Oka Shipyard laid down the keels of two bilge water collector vessels of about 520 tons deadweight of RST38 project.
Customer - FSUE "Rosmorport".
The RST38 was designed by the Marine Engineering Bureau.
Is a steel single-deck self-propelled vessel of limited R3-RSN navigation area, twin-screw, tank, with engine room and deckhouse aft, with cargo tanks, with double bottoms and double sides extending the full length and height of the cargo tanks.
The area of operation is assumed in the waters of the ports of Vanino and Sovetskaya Gavan, in the area of responsibility of the Vanino branch, as well as in the waters of the Northwest Basin Branch.
Purpose of the vessel of the project RST38:
• collection of oily water (bilge water) from vessels, its sedimentation, separation with pumping oil products into the tank of oil residue and delivery of oil residue ashore in the storage, separated clean water ashore or overboard in permitted areas;
• collection of sewage and garbage from vessels with their transportation and delivery to onshore treatment facilities.
With appropriate retrofitting, the vessel can be used as an auxiliary transport to deliver oil recovery equipment and booms to the spill site (outside the oil spill slick area).
The RST38 project vessel has the following main characteristics:
Overall length - 49.21 m;
Length between perpendiculars - 45.00 m;
Overall width - 8.82 m;
Width - 8.40 m;
Depth - 4.40 m;
SW Draught - 3.0 m;
Speed - 9.0 knots;
Autonomy - 10 days.
Builds on the class of RS: KM  Ice 3 (hull; machinery) R3-RSN AUT3 A-Thruster(M) Bilge water removing ship.
The vessel's structure is reinforced with Ice 3 class of ice reinforcements.
In the stern part of the vessel there are two full-turn propeller-rudder columns with fixed pitch propellers without attachments, which provide the vessel with the required speed and steerability. Drive to steering columns from main diesel engines is carried out through cardan gear and elastic coupling.
To improve controllability at low speeds, when passing narrow passages and when mooring, the vessel is provided with a bowthruster of 55 kW power "propeller-in-tube" type with a fixed pitch propeller.
A hydraulic crane with a capacity of 0.89 tons and an outreach of 14 m is provided for filing and removing hoses, reloading waste and other auxiliary operations.
The wheelhouse is designed with an all-round view to allow one person to steer the vessel.
The cargo system of OWS provides closed receiving of OWS (bilge water) from vessels, treatment and discharging of OWS by vessel pumps. There is a 3-stage settling of oily water with pumping from tank to tank by two pumps.
The vessel's crew consists of six people.
The keel of the lead vessel is laid down on December 23, 2021.
The keel of the second vessel is laid down on December 23, 2021.
