Formerly the battleship Tsessareivich, this ship serves to support construction sites in remote areas of Russia's Pacific and Arctic coasts.

Russian mobile crane Trud, laid down 1903

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)


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.

Distribution of weights:

Machinery ........................ 1275 tonnes = 10 pct
Hull and fittings; equipment ..... 2763 tonnes = 21 pct
Fuel, ammunition, stores ......... 4146 tonnes = 31 pct
Miscellaneous weights ............ 5000 tonnes = 38 pct
13184 tonnes = 100 pct

Estimated metacentric height, 1.1 m

Displacement summary:

Light ship: 9038 tonnes
Standard displacement: 9302 tonnes
Normal service: 13184 tonnes
Full load: 16236 tonnes

Loading submergence 1903 tonnes/metre


Estimated overall survivability and seakeeping ability:

Relative margin of stability: 1.09

Shellfire needed to sink: 6728 kg = 220796.0 x 1.3-cm shells
(Approximates weight of penetrating
shell hits needed to sink ship,
not counting critical hits)

Torpedoes needed to sink: 2.4
(Approximates number of 'typical'
torpedo hits needed to sink ship)

Relative steadiness as gun platform, 70 percent
(50 percent is 'average')

Relative rocking effect from firing to beam, 0.00

Relative quality as a seaboat: 1.69


Hull form characteristics:

Block coefficient: 0.60
Sharpness coefficient: 0.45
Hull speed coefficient 'M' = 4.99
'Natural speed' for length = 19.6 knots
Power going to wave formation
at top speed: 43 percent

Estimated hull characteristics and strength:

Relative underwater volume absorbed by
magazines and engineering spaces: 73 percent

Relative accommodation and working space: 82 percent

Displacement factor: 175 percent
(Displacement relative to loading factors)

Relative cross-sectional hull strength: 1.04
(Structure weight per square
metre of hull surface: 465 kg)

Relative longitudinal hull strength: 1.92
(for 4.00 m average freeboard;
freeboard adjustment -0.88 m)

Relative composite hull strength: 1.10
