The Liberian motor tanker Silver Castle was on a voyage
from Ras Tanura to Moanda, Zaire loaded with 18,000 tons of crude oil
when she was involved in a collision in dense fog
with the South Africa steamship, S.A. Pioneer
about 80 miles north of Port Elizabeth
in last 33.48S long 26.47E on April 20, 1972.
Immediately catching fire, holed and leaking oil
the Silver Castle was abandoned by her crew, 16 of whom died.
The other 19 were subsequently safely picked up.
The tanker drifted, her fire being extinguished by HMS Lowestoft,
until she was towed into Mossel Bay by the tug Euroman.
Extensively gutted, the Silver Castle was towed out to sea,
and deliberately sunk by bombing by South African Buccaneer
