Sea Quest (drilling rig)

Sea Quest (drilling rig) is a earth 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 Sea Quest (drilling rig) rather than just read about it. In short: The Sea Quest was a semi-submersible drilling rig. She discovered the UK's first North Sea oil on 14 September 1969 in the Arbroath Field.

Key takeaways

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

Reference excerpt

The Sea Quest was a semi-submersible drilling rig. She discovered the UK's first North Sea oil on 14 September 1969 in the Arbroath Field. She also discovered the first giant oil field named Forties on 7 October 1970. The Sea Quest was built by Belfast shipbuilders Harland & Wolff for BP at a cost of £3.5 million and launched on 8 January 1966. The entire structure was 320 feet (98 m) high and weighed 150,000 tons, including three legs each 35 feet (11 m) in diameter and 160 feet (49 m) long that could be partially filled with water to control the height of the platform above the sea. In 1977, Sea Quest was sold to Sedco (now part of Transocean) and renamed Sedco 135C. She was towed to the west coast of Africa. On 17 January 1980, while drilling in the Warri area, Nigeria, a blowout occurred and the rig sustained extensive fire damage. The rig was then deliberately sunk in deep water.

Worked examples

Example 1 — a first encounter with Sea Quest (drilling rig)

Start with the simplest possible case. Write down what Sea Quest (drilling rig) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth 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 Sea Quest (drilling 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 Sea Quest (drilling 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 Sea Quest (drilling rig)

In research: Sea Quest (drilling rig) appears in earth 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 Sea Quest (drilling 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: Sea Quest (drilling rig) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Collapsed oil platforms, Drilling rigs, Merchant ship stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Sea Quest (drilling 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.
