Je recherche des Information sur c'est deux Bateau en Ciment ,ils sont coulé au endroit Cap Roux a Oran-Algérie
d’après ce que je connais ,ils ont été construits en 1919 en Angleterre. Après la 1ere guerre mondiale, il y avait une pénurie des matériaux et notamment du fer, alors un ingénieur a imaginé construire des bateaux en béton, il en a construit 5 dont 4 qui ont été vendus au port d’Oran en 1923. Les barges à charbon étaient stationnées dans les ports au début du XXème siècle et alimentaient les autres bateaux en charbon,,il y en a deux au cap roux, un ou deux au corailleurs(les andalouses)
"Cretell" and "Cretecoal" were built by Christiani & Nielsen, Tilbury, Essex.
Dimensions 185' x 35'. 16' depth of hold, 18' depth to keel. 14'4" draught. All 689 GRT, launched 1.5.19 and completed 11.19.
"Cretecoal", yard # 500, became hulk at Oran in 1923 and was deleted in ???? from Lloyd's Register.
"Cretell" was yard # 504, sold to France in 1923 and deleted from register 1927.
The other two sold to France were "Cretecoke" (yard # 501), sold to France in 1923 and deleted from register in 1927, and "Cretacite", yard # 503, sold to France in 1923. 29.1.30 she sprung a leak and sank at Oran.
These vessels (and a fifth one, the "Cretefuel") were completed as coaling barges for the Admiralty. They were all "Launched" on the same day, having been built simultaneously in a concrete dry dock excavated in Tilbury Docks, and they were floated out through a special channel 40 ft. wide - which was equipped with concrete lock gates. The sides of all the barges were built in pre-cast sections and were raised into position with special tackles.
The coal handling gear on the vessels consisted of four Temperley transporters with winches, and electric light plant for coaling at night. Two boilers were each 13,5 ft. x 5,5 ft., the heating surface was 300 sq.ft. and there was also surface condensing plant.
The steel masts were 70 ft. high and had a diameter of two feet. The transporters had an action radius of 65 ft. and a lifting capacity of 30 cwt in each bucket.
The Temperley portable transporter consisted of a steel beam which was slung from the derrick of the ship's mast by wire ropes and held in position by guy stays. A trolley travelled backward and forward on this beam between loading and discharging ends and all the operations of hoisting, travelling and lowering the load was effected by the simple operation of hauling in and paying out one rope. It could be worked by a ship's winch, although a special quick-working large-barrel winch ensured quicker speed of work.
The loads were usually handled in tilting skips, and although, generally, each was of 30 cwt, 2-ton loads were handled on occasions. Speed of work was approx. 40 trips per hour, this giving a good daily replenishment rate for coaling of ships.

By the way: the two barges at Le Havre were of a different type built in France - there is a thread about them and their sisterships in this forum, if you want know more about them.
