SS Darien (1924)

SS Darien was a refrigerated cargo ship of the United Fruit Company. Cammell Laird of Birkenhead, England built her as MV La Marea, completing her in 1924.[1] She had been renamed Darien by 1930[1] and had been re-engined from diesel to steam by 1931.[2]

The ship was owned by a United Fruit subsidiary, Balboa Shipping Co, Inc, which registered her under the Panamanian flag of convenience.[1] She was still in service in 1945.[4]

Building

La Marea was built as a diesel-electric motor vessel, with four four-cylinder single-acting two-stroke diesel engines.[1] They powered electric generators that supplied current to a single electric propulsion motor rated at 981 NHP that turned a single propeller shaft.[1] She was equipped with both submarine signalling and wireless.[1]

Rebuilding

By 1930 Darien had been lengthened by 27.5 feet (8.4 m), which increased her gross register tonnage by 592 tons.[1] By 1931 she had been converted from diesel-electric to steam turbo-electric propulsion.[2] Her four diesel engines and four electric generators were replaced with two water-tube boilers and a single British Thomson-Houston turbo generator.[2] Her boilers had a combined heating surface of 8,660 square feet (805 m2)[2] and a working pressure of 400 lbf/in2.[2] The conversion reduced Darien's power output to 839 NHP.[2]

Darien was not United Fruit's first turbo-electric ship. As early as 1921 Workman, Clark and Company of Belfast had completed SS San Benito for Balboa Shipping, again using a BT-H turbo generator and propulsion motor.[5]

gollark: And if you're in (the) (Ant)[Aa]rctic(a), you run into similar problems because of the broken daynight cycle.
gollark: And prayers take place at certain times of day, which of course causes problems with no real day/night cycle available.
