Russian mobile crane Trud, laid down 1903
Trud was converted from the predreadnought battleship Tsesarevich. She has found employment supporting construction projects in remote areas with poor port infrastructure.

Length, 117.6 m x Beam, 22.6 m x Depth, 8.2 m
13184 tonnes normal displacement (9302 tonnes standard)

Main battery: 1 x 1.3-cm

Weight of broadside: 0 kg

Hull unarmored

Maximum speed for 6374 indicated kw = 16.00 knots
Approximate cruising radius, 25800 nm / 10 knots

Typical complement: 307-400


Estimated cost, $1.979 million (£495,000)

Remarks:

Ship has slow, easy roll; a good, steady gun platform.

Excellent seaboat; comfortable and able to fight her guns
in the heaviest weather.

Magazines and engineering spaces are roomy, with superior
watertight subdivision.
