Reference excerpt

The RV Denar 2 is a Turkish research and survey vessel owned by TOMA Maritime S.A. Istanbul, Turkey and operated 2E Maritime in Istanbul, Turkey. She was built by Sønderborg Skibsværft A/S in Sønderborg, Denmark. Christened Leila Bech, she was launched on January 12, 1974, and was commissioned under the Danish flag on May 1, 1974. After sailing under the Panamas and Ilaian flags, she was finally purchased by the Turkish private maritime company in October 2013 as the first and so far the only non-governmental vessel of her kind. She was renamed "Denar", short for "Deniz Araştırmaları" (literally: sea surveys). She made her first operation in the Mediterranean Sea for the Northern Cyprus Water Supply Project, an international water diversion project designed to supply water for drinking and irrigation from southern Turkey to Northern Cyprus via undersea pipeline. With the help of her two remotely operated underwater vehicles (ROV), she was put into service at the construction projects of Marmaray, İzmit Bay Bridge and Yavuz Sultan Selim Bridge in addition to deep sea surveys.

Characteristics

Vessel Denar 2 is 78.80 m (258 ft 6 in) long, with a beam of 13.25 m (43 ft 6 in) and a max. draft of 4.16 m (13 ft 8 in). Assessed at 2,033 GT, 2,997 DWT and 610 NT, the ship is propelled by a 1,589 kW (2,131 hp) diesel engine of type Alpha Burmeister & Wain 16V23HU - 4S 16cyl-Vee 225 x 300 Trp 750 rpm. She has a top speed of 11 knots (20 km/h) with 10 knots (19 km/h) in service. She has capabilities for bathymetric surveys, oceanographic surveys, geological surveys, geophysical surveys and geotechnical engineering. Furthermore, she can be used in coastal management and ocean engineering applications such as submarine pipeline applications and for dredging services. She has three cranes capable of lifting loads between 3.5–10 tonnes, and an A-frame for 20 tonnes. She is equipped with following instrumentation: She carries two ROVs: Work-class ROV (TRV-HD) capable of diving up to 1,000 m (3,300 ft) and carrying payloads up to 136 kg (300 lb):

Dimensions: 170 cm × 138 cm × 91 cm (67 in × 54 in × 36 in) Weight: 795 kg (1,753 lb), Sonar: MS 1000 Sonar Head Underwater cameras (4): HD Sony Zoom Camera, low-light camera, 360° rotating camera and color manipulator camera.

Worked examples

Example 1 — a first encounter with RV Denar 2

Start with the simplest possible case. Write down what RV Denar 2 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 Denar 2 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 Denar 2 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 Denar 2

In research: RV Denar 2 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 Denar 2 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 Denar 2 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1974 ships, IMO numbers, Research vessels of Turkey, so understanding it makes those chapters shorter.
In everyday life: Look for RV Denar 2 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.
