| Term | Definition | Example Usage |
|---|---|---|
| Icebreaker | A ship designed to navigate through ice-covered waters, typically used for commercial or scientific purposes. | Russia is building the world’s largest icebreaker, the “Leader” project, to ensure year-round shipping along the Northern Sea Route. |
| Nuclear Installation | A system that generates power using nuclear energy, often used in icebreakers to provide energy for propulsion and other systems. | The “Leader” project features a 120-megawatt nuclear installation to power its propulsion systems. |
| Ice-Breaking Capacity | The thickness of ice that an icebreaker can break through, measured in feet or meters. | The “Leader” project has an ice-breaking capacity of up to 9.5 feet thick. |
| Propeller | A device that propels a ship through the water, typically driven by an engine or other power source. | The “Leader” project features four electrical propellers, a first in icebreaker construction, designed to reduce friction and improve efficiency. |
| Double Hull | A design feature in which a ship has two hulls, one inside the other, to improve safety and reduce the risk of flooding in the event of a collision or other incident. | The “Leader” project features advanced safety systems, including a double hull and fire extinguishing systems, to ensure crew safety. |
| Life Support System | A system that provides essential services, such as air, water, and waste management, to support human life on a ship or in a remote location. | The “Leader” project features advanced life support systems, including single-person cabins, a gym, pool, sauna, and public spaces, to support its crew of 60 people for four months at a time. |
| Supercomputer Simulation | The use of advanced computer simulations to model and analyze complex systems, often used in engineering and scientific research. | The “Leader” project underwent wind tunnel testing and supercomputer simulations for safe helicopter landings. |
| Wind Tunnel Testing | A type of testing in which a scale model of an object, such as a ship or aircraft, is subjected to controlled airflow to simulate real-world conditions. | The “Leader” project underwent wind tunnel testing to optimize its design for seaworthiness and comfort. |
| Hydrocarbons | A type of fossil fuel, including oil, natural gas, and coal, often used as a source of energy. | Russia is building the “Leader” project to ensure year-round shipping along the Northern Sea Route, a crucial corridor for delivering hydrocarbons from the Yamal Peninsula to Southeast Asia. |

Using the Passive Voice in Technical Descriptions
| Explanation |
|---|
| The passive voice is often used in technical descriptions to focus on the action rather than the doer. This is particularly useful when the doer is not important or is unknown. In the given text, the passive voice is used to describe the technical specifications, innovative features, and testing of the “Leader” icebreaker. For example, “Displacement: 70,000 tons” and “Extensive testing at a research center, including electric wave generators and wind tunnels” use the passive voice to emphasize the action rather than the person performing the action. |
