PROJECT SDS14C
Sea diving ship
Type: sea-going diving vessel with a sloping stem and a transom stern end, with a wheelhouse in the middle part, and with the engine room located at the stern and a fixed-pitch propeller (FPP) in a rotating nozzle
Purpose:
- Performing light diving operations at depths of up to 45 meters
- Participation in emergency rescue, ship-lifting and underwater engineering works within the scope of the means installed on the ship
- Inspection of the bottom of water areas, sunken objects, underwater parts of ship hulls and waterside structures
Navigation area: Restricted: harbour, roadstead and coastal navigation in a 20-mile coastal zone with a significant wave height up to 2.0 m with maximum distance from the nearest port of safe anchorage not more than 50 miles.
The operation area – Caspian Sea.
The operation conditions in ice: according to the ice class «Ice Class IE».
