Where ships go to die

At the end of their working lives, the large ships can be broken up. This can be done by beaching large ships and using welding torches to cut the steel. This steel can then be recycled by adding into BOS vessel in steelmaking (to recover heat) or melted using any kind of furnace.

This video shows a ship being beached at Gadani Pakistan:

Modern container ships are made from welded steel plates and can have length of up to almost 400 m. They carry huge numbers of inter-modal containers (which can also be carried by truck or train).

The first container ships were converted world war 2 T2 tankers typically 152.9 m in total length and 20.7 m in width (beam). The largest container vessel today is MSC Oscar, 395.4 m in length and 59 m wide and capable of carrying 19224 containers (TEU — twenty foot equivalent unit).

As these ships travel the globe they are bashed by waves, in this video we can see the displacements this causes inside the vessel.

Video shows the container ship MSC Busan in heavy seas. In the video at around 11 s a wave of height approx. 7-8 meters hits the vessel.

Biggest Ship ever

The largest ship to date is was the Seawise Giant built by Sumitomo Heavy Industries at Oppama shipyard. A ship so big that it takes Top Gear presenter Jeremy Clarkson to describe it.


Seawise Giant had several names since it’s building from 1974-1979 and it’s scrapping in 2009, including Knock Nevis. Here is a comparison between some of the other largest ships in the world.

The largest ships so far.

Seawise Giant was the longest ship ever constructed, longer than the height of many of the world’s tallest buildings, larger than the Petronas Twin Towers at 451.9 m (1,483 ft). In December 2013 Prelude FLNG became the longest ship ever constucted which measures 488 m (1,601 ft), built by Samsung Heavy Industries at Geoje Shipyard. Also four Batillus-class supertankers operated from 1976-2003 built at the Chantiers de l’Atlantique shipyards in France which had a larger gross tonnage.

Which is better, iron or gold?

To Croesus, King of Lydia, on being shown his golden treasures, Solon said: “If another comes who hath better iron than you, he will take away your gold.”

King Croesus introduces gold coinage (adopted by the Persians after they defeated him) although his coins used a gold-silver alloy (electrum) based on the composition of the alluvial deposits. When he asked the Delphic oracle of Amphiarus if he should wage a campaign against Cyrus the Great of Persia or seek an alliance, the Delphic advice was that if Croesus attacked the Persians, he would destroy a great empire.

What I learnt from KPOP (Part 2)

From Orange Caramel’s ‘까탈레나(Catallena)’ MV I learnt that is is acceptable to eat sushi using no utensils.

Further, a brief research on the `internets’ tells me that sushi is traditionally a finger food so it completely acceptable or even preferred to eat it that way.

  • Nigiri-sushi (hand-shaped sushi — may fall apart if using chopsticks) — fingers.
  • Cone sushi or hand rolls — fingers.
  • Rolled sushi — fingers or chopsticks.
  • Chirashi-zushi (scattered sushi) is eaten with chopsticks (maybe fork).

The song 까탈레나(Catallena), samples a Punjabi wedding folk song — Jutti Meri Jandiye, containing the lyrics “Jutti Meri Oye Hoi Hoi, Paula Mera Oye Hoi Hoi”, you can find lyrics and translation at kkromanized.



Safety First — Wurzels star in Farm Safety Song

Iconic band “The Wurzels” has teamed up with students at Moreton Morrell College to produce a farm safety music video promoting farm safety. The video promotes the “Yellow Wellies Campaign” of the Farm Safety Foundation/ NFU Mutual. The campaign asks “Who Would Fill Your Boots?” to farmers in the case of injury or death at work.

According to the UK Health and Safety Executive, 27 people died in farm accidents in the year to April 2014. Farming often involves working long hours with Heavy machinery, livestock, exposed to the elements.

Whilst farming accounts for 1.5% of the UK’s workforce, it accounts for 15-20% of workplace fatalities.

Have a safe day.
