Jumboised to 120,000 dwt
Cargo 120,000 ts of BP oil for
Milford Haven
Navigational error caused
grounding ripping open 6 tanks
31,000,000 gallons of oil leaked
Oil spread along the sea
between England and France

Amoco Cadiz 1978
•
•
•
•
1974 built Amoco Cadiz carrying
227,000 tonnes of crude oil
ran aground off the coast of Brittany,
France at 10:00 p.m. on March 16, 1978
The whole cargo spilled out as the
breakers spilt the vessel in two,
progressively polluting 360 km of
shoreline
At the time this was the largest oil spill
by tanker ever registered.

FPSOs/FSUs
a.
b.
c.
FPSOs and FSUs are not oil tankers and are not to be used for
the transport of oil except that, with the specific agreement by
the flag and relevant coastal States on a voyage basis,
Conversion of an oil tanker to an FPSO or FSU or vice versa
should not be construed as a major conversion as defined in
regulation 1(8)
There are five categories of discharges that may be associated
with the operation of an FPSO or FSU:
1.
2.
3.
4.

machinery space drainage;
offshore processing drainage;
production water discharge;
displacement water discharge; and
contaminated seawater from operational purposes such as
produced oil tank cleaning water, produced oil tank hydrostatic
testing water, water from ballasting of produced oil tank to carry
out inspection by rafting.
