Bedrock and Shalestone

The Bedrock and The Shalestone are multipurpose icebreaker and platform supply vessels commissioned into service by the Will of Iron. They are used as auxiliary vessels during extended oceanic missions.

General Characteristics
The matching pair sport an overall length of around 80 meters with a moulded breath of 20 meters and a depth of 9 meters. The hull is reinforced with double platings of steel and is strengthened by internal cross members. The design provides greater width at the bow than the stern to improve maneuverability and in the case of ice, the design increases the width of the ice channel and reduces friction between the hull and the ice. The ghost iron ice belt also helps reduce friction and protects the steel plating from abrasion at the water line.

Each ship is also equipped with a 210 ton towing winch and stern notch for assisting other ships while the oblique bridge maximizes visibility from the starbard side steering position.

Power and Propulsion
Each ship is powered by a six engine-generator-engine set, totalling twelve V12 high-speed diesal engine. While having a large number of smaller engines increases the flexibility and efficiency of the power system, and the engines can be started and stopped on demand and the running engines operate at maximum efficiency, the ship requires more maintenance hours to keep them in shape.

The propellers are rotatable, providing better maneuverabiltiy and making the presence of a rudder unnecessary. They are electrical controlled, which is fed by the main engine set.
