Petrobras 36

Petrobras 36 is a mathematics 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 Petrobras 36 rather than just read about it. In short: Petrobras 36 (P-36) was a semi-submersible oil platform. Prior to its sinking on 20 March 2001, it was the largest in the world.

Key takeaways

Petrobras 36 belongs to mathematics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Petrobras 36 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Petrobras 36 from memory before moving on to harder problems.

Reference excerpt

Petrobras 36 (P-36) was a semi-submersible oil platform. Prior to its sinking on 20 March 2001, it was the largest in the world. It was operated by Petrobras, a semi-public Brazilian oil company headquartered in Rio de Janeiro. The proximate cause for the sinking was a series of explosions that killed 11 crew. In terms of lives lost, it was the worst offshore oil and gas accident in Brazil since 1984, when a rig blowout and explosion caused 36 fatalities, and the worst worldwide since the explosion of a platform off Nigeria in January 1995, which killed 13.

Worked examples

Example 1 — a first encounter with Petrobras 36

Start with the simplest possible case. Write down what Petrobras 36 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, 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 Petrobras 36 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 Petrobras 36 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 Petrobras 36

In research: Petrobras 36 appears in mathematics 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 Petrobras 36 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: Petrobras 36 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1994 ships, 2001 disasters in Brazil, 2001 disestablishments in Brazil, so understanding it makes those chapters shorter.
In everyday life: Look for Petrobras 36 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.
