RV Cirolana

RV Cirolana 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 RV Cirolana rather than just read about it. In short: RV Cirolana was a fisheries research vessel used by the Centre for Environment, Fisheries and Aquaculture Science and originally built for the Ministry of Agriculture, Fisheries and Food (United Kingdom).

Key takeaways

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

Reference excerpt

RV Cirolana was a fisheries research vessel used by the Centre for Environment, Fisheries and Aquaculture Science and originally built for the Ministry of Agriculture, Fisheries and Food (United Kingdom). She was initially intended to replace the RV Ernest Holt operating in arctic waters around Bear Island (Norway) and Iceland, but following the Cod Wars spent most of her working life conducting fisheries surveys in the North Sea, Irish Sea and English Channel. For the first part of her career RV Cirolana was based in the fishing port of Grimsby, but after bridge and channel dredging work improved the depth, it was deemed acceptable to bring her to Lowestoft. Her engines etc were housed in a sound and vibration proof enclosure which was supported on many pneumatic dampers. She had main electric propulsion motors which powered the screws. All ancillaries were also damped using anti-vibration mountings. All this damping was aimed at reducing noise/vibrations through the superstructure to enable the ability to conduct acoustic surveys of fish populations . She was built in 1969, by Ferguson Shipbuilders, and delivered in 1970. She was placed out of service in approximately 2003 and replaced by RV Cefas Endeavour. On Friday 24 June 1977 RV Cirolana participated in the Silver Jubilee Fleet Review at Spithead in the Solent

Service as a fisheries research vessel RV Cirolana was the principle fisheries research vessel employed by the Ministry of Agriculture, Fisheries and Food (United Kingdom) throughout the period 1970 to 2003. She was used extensively for fish stock surveys and oceanographic investigations. In the early 1970s RV Cirolana conducted extensive surveys around Greenland, Iceland and the Faroe Islands as well as several trips to the Labrador Sea. In 1973-4, she carried out deep-water surveys down to depths as great as 1200m along the Atlantic continental slope to the west of the British Isles and at banks further out in the Atlantic - Rockall, Hatton, Rosemary Bank and Bill Bailey's. There were ongoing issues with Cirolana's impellers being fouled by floating netting, which would then require that the ship navigate back to a safe harbour on bow thrusters alone, followed by the hire of professional divers to remove the obstruction. In 1999, and again in 2000, she rediscovered a post-medieval wreck at 51.474930N, 5.200480W. The wreck was first reported in July 1945, and is 84m long.

Worked examples

Example 1 — a first encounter with RV Cirolana

Start with the simplest possible case. Write down what RV Cirolana 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 RV Cirolana 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 RV Cirolana 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 RV Cirolana

In research: RV Cirolana 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 RV Cirolana 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: RV Cirolana is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1969 ships, IMO numbers, Research vessels of the United Kingdom, so understanding it makes those chapters shorter.
In everyday life: Look for RV Cirolana 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.
