Vladimir Kavrayskiy (ship)

Vladimir Kavrayskiy (ship) is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Vladimir Kavrayskiy (ship) rather than just read about it. In short: Vladimir Kavrayskiy (Russian: Владимир Каврайский) is a former Soviet and later Russian Navy icebreaking hydrographic survey vessel today used as a floating barracks PKZ-86 in Murmansk. Description In the mid-1950s, the Soviet Union began developing a new diesel-electric icebreaker design based on the 1942-built steam-powered icebreaker Eisbär to meet the needs of both civilian and naval operators.

Reference excerpt

Description

In the mid-1950s, the Soviet Union began developing a new diesel-electric icebreaker design based on the 1942-built steam-powered icebreaker Eisbär to meet the needs of both civilian and naval operators. Built in various configurations until the early 1980s, the Project 97 icebreakers and their derivatives became the largest and longest-running class of icebreakers and icebreaking vessels built in the world. Of the 32 ships built in total, the single-vessel Project 97B subclass featured a longer hull, additional facilities for hydrographic surveys, increased accommodation, and a helipad. Vladimir Kavrayskiy is 70.1 metres (230 ft) long overall and has a beam of 18.1 metres (59 ft). Fully laden, the vessels draws 6.4 metres (21.0 ft) of water and has a displacement of 3,450 tonnes (3,400 long tons). Its three 1,800-horsepower (1,300 kW) 10-cylinder 13D100 two-stroke opposed-piston diesel engines are coupled to generators that powered electric propulsion motors driving two propellers in the stern and a third one in the bow. Compared to baseline Project 97 icebreakers, Project 97B has a longer hull and greater displacement providing increased range and autonomy time. Furthermore, the vessel is fitted for hydrographic surveys with additional scientific facilities and accommodation for additional crew and 17 scientific personnel.

History Vladimir Kavrayskiy was laid down at Admiralty Shipyard in Leningrad on 25 February 1969, launched on 31 October 1969, and delivered on 31 December 1969. The vessel was named after Vladimir Vladimirovich Kavrayskiy (1884–1954), a Soviet astronomer, geodesist and cartographer. The vessel entered service with the separate division of oceanographic research vessels of the hydrographic service of the Northern Fleet. During its service as a hydrographic survey vessel, Vladimir Kavrayskiy completed 37 expedition voyages and covered a distance of 380,000 nautical miles (700,000 km; 440,000 mi). Following the dissolution of the Soviet Union, Vladimir Kavrayskiy was passed over to the Russian Navy on 26 July 1992. In July 2011, Vladimir Kavrayskiy was reassigned to the detachment of support vessels of the Northern Fleet and renamed PKZ-86 in the following spring. As of 2023, the vessel remains in service as a stationary barracks ship in Murmansk.

Worked examples

Example 1 — a first encounter with Vladimir Kavrayskiy (ship)

Start with the simplest possible case. Write down what Vladimir Kavrayskiy (ship) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Vladimir Kavrayskiy (ship) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Vladimir Kavrayskiy (ship) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Vladimir Kavrayskiy (ship)

In research: Vladimir Kavrayskiy (ship) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Vladimir Kavrayskiy (ship) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Vladimir Kavrayskiy (ship) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1969 ships, Icebreakers of Russia, Icebreakers of the Soviet Union, so understanding it makes those chapters shorter.
In everyday life: Look for Vladimir Kavrayskiy (ship) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
