Kolskaya (jack-up rig)

Kolskaya (jack-up rig) 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 Kolskaya (jack-up rig) rather than just read about it. In short: Kolskaya was a jack-up rig operating in the Russian Far East. It was built by Rauma-Repola in Pori, Finland in 1985 and was owned by the Russian company ArktikmorNeftegazRazvedka (AMNGR), a subsidiary of Zarubezhneft.

Key takeaways

Kolskaya (jack-up rig) belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Kolskaya (jack-up rig) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kolskaya (jack-up rig) from memory before moving on to harder problems.

Reference excerpt

Kolskaya was a jack-up rig operating in the Russian Far East. It was built by Rauma-Repola in Pori, Finland in 1985 and was owned by the Russian company ArktikmorNeftegazRazvedka (AMNGR), a subsidiary of Zarubezhneft. Kolskaya was an independent leg cantilever type jack-up rig. It was 69 metres (226 ft) long and 80 metres (260 ft) wide, and could accommodate up to 102 people. Its rated water depth for operations was 328 feet (100 m). Its drilling depth was 21,325 feet (6,500 m).

Capsize and sinking On December 18, 2011, the rig, which was under tow during a fierce storm, capsized and sank in the Sea of Okhotsk. It was being towed by the icebreaker Magadan and the tugboat Neftegaz-55 having just completed an exploration well for Gazprom off the Kamchatka Peninsula. The incident happened some 200 kilometres (120 mi) off the coast of Sakhalin island, in waters more than 1,000 metres (3,300 ft) deep. In terms of operational safety, the towing operation's compliance with best practices was doubtful since the platform’s manufacturer explicitly stated that "towing is prohibited in the winter, in winter seasonal zones." A search and rescue effort began as soon as the rig sank and was halted five days later on December 22. Of the 67 people known to have been aboard Kolskaya, 14 had been rescued and 36 more were listed as missing. Only 17 bodies had been recovered. With 53 declared missing or dead, it was the largest number of casualties in an accident the Russian oil sector has ever experienced.

Worked examples

Example 1 — a first encounter with Kolskaya (jack-up rig)

Start with the simplest possible case. Write down what Kolskaya (jack-up rig) 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 Kolskaya (jack-up rig) 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 Kolskaya (jack-up rig) 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 Kolskaya (jack-up rig)

In research: Kolskaya (jack-up rig) 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 Kolskaya (jack-up rig) 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: Kolskaya (jack-up rig) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1985 ships, 2011 disasters in Russia, 2011 industrial disasters, so understanding it makes those chapters shorter.
In everyday life: Look for Kolskaya (jack-up rig) 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.
