Oil drill rig Platforms.

SERTAO.

Anchored at Port Talbot in South Wales, U.K. this ship is surprisingly large for its work of oil exploration and awaits a new buyer? 

But since the Belfast shipyard Harland and Wolf has finally gone under and the lack of new construction of oil rigs Sertao  may soon be bought up for new work in the Artic ocean for fossil fuels?

She is a ship with everything I think one needs to experimentally drill and be serviced to other vessels with her own helicopter deck and various cranes and the like?

One needs to get down to Port Talbot Tata steel dock or the Aber Afan river to see her before she goes, perhaps never to be seen again?

'Under Water. Part-Two.

World War-11 (1939-45)

It was during these six years of war that the submarine came into its real value as a weapon, with the Nazi-German navy in the early years being a menace to Allied shipping. The Wolf packs were very successful, until the German Enigma code and Sonar was broken and invented.

These submarines remained cramped to live and operate in, but they could stay underwater for longer and were faster. In fact only after world war-II was it discovered how much of a 'Coffins were the U-Boats.

It takes a certain type of person to be a submariner, the confined and underwater life would mark out men and woman to this present day. Because the submarine now is more about going deeper and not being seen at all.
