Wasn't it something to do with the Suez Canal? When the ships were
commissioned, their 'hugeness' was needed because the canal was closed and
the oil had to take the long way round.
But as soon as the canal re-opened the supertankers were less viable than
smaller vessels. Didn't this change happen before the last supertanker was
actually launched?
That's what I seem to remember anyway - mind that could be something to do
with me being one of the happy people "from the South" (and actually in that
dump of a ground in North London on that 1973 day).

Hi Mike,
I looked it up
The best explanation I could find was on this page
http://baegis.ag.uidaho.edu/~myron/html/tanker.htm
VLCC Very Large Crude Carrier
a.. 1971 Seventy-two new VLCCs are entering service, altogether 208 VLCCs
are in operation.
a.. 1973 OPEC increases the cost of oil by 70%. Yom Kippur War breaks out,
and the Suez Canal is closed again.
a.. Sunderland win the FA Cup
a.. 1974 A crisis situation develops in the tanker sector worldwide, yet
still another 100 VLCCs per year are under construction.
a.. 1975 Worldwide oil consumption decreases by 8%. Newbuilding orders are
being cancelled, 85 tankers are placed into lay-up.
a.. 1976 The 'Batillus' with 550,001 DWT becomes the first tanker to exceed
half-a-million tons deadweight.
a.. 1977 Several tanker owning companies go 'belly-up', shipyards are in
critical situations.
a.. 1978 Some of the the earliest VLCCs are being scrapped
a.. 1980 Hong Kong ship owner C.Y.Tung's 'Seawise Giant' with 564,839 DWT is
the largest tanker and the largest man-made structure in the world. After
just two voyages goes into layup and serves as storage vessel later on. Sold
to Norway and re-named 'Jahre Viking'. Specs: Length 1,504', beam 226',
draft 98', 260,851 GRT, 13 knots.
a.. 1980-88 Gulf War between Iran and Iraq, tankers under attack.
b.. 1984 210 tankers are in layup, representing 43% of the world's tanker
fleet. ULCCs have become uneconomical.
c.. 1986 To this date 283 VLCCs have been sold for scrap.
d.. 1987 Supply and demand for tankers have found their balance; oil
prices and freight rates are on the increase.
e.. 1992 Again a surplus of VLCCs on the market. Freight rates sinking
again.
f.. 1996 The 1,000th VLCC is being delivered, the 'Meridian Lion'.
Altogether six vessels with more than 500,000 DWT have been constructed over
the last 20 years.
The worst tanker accidents, many of them due to human error:
a.. 1967 The 'Torrey Canyon' runs onto a reef and breaks apart, 117,000 tons
of oil are leaked into the sea, resulting in disastrous oil pollution. (see
stamps)
a.. 1968 Newcastle win the 'Fairs Cup' .
a.. 1969 Three tankers explode while in ballast condition, 'Marpessa' and
'Mactra' sink right away, 'King Haakon VI' is heavily damaged.
a.. 1974 'Metula' runs aground in the Straits of Magellan, 50,000 tons of
oil are lost.
a.. 1975 'Berge Istra' with 227,557 DWT explodes and sinks within a few
minutes.
a.. 1976 'Urquiola' explodes and strands near La Coruna. 95,000 tons of oil
polluting the shore.
a.. 1978 'Amoco Cadiz' grounds near Brest and breaks apart, spilling 223,000
tons of oil.
a.. 1979 'Atlantic Empress' and 'Aegean Captain' collide in the Caribbean,
spilling 276,000 tons of oil.
a.. 1980 The burning tanker 'Irene's Serenade' sinks in Navarino Bay,
emitting 100,000 tons.
a.. 1980 Three more VLCCs suffer explosions and immediate sinking, the
'Maria Alejandra', 'Albahaa', and 'Mycene'.
a.. 1989 'Exxon Valdez' runs aground on an Alaskan reef, spilling 42,000
tons, resulting in disastrous pollution. The 'Chark 5' suffers an explosion
off the Canary Islands, losing 89,000 tons of oil.
a.. 1996 The 'Sea Empress' goes on the rocks near Milford Haven spilling
85,000 tons of oil.
a.. 1999 'Erika' breaks apart in rough seas in the Bay of Biscay, spilling
17,000 tons of oil.
Single hull oil tankers are to be phased out in 2015. That was decided by
the International Maritime Organisation (IMO) in 1999. Shortly before the
single hull oil tanker Erika had collapsed off the French coast. It leaked
more than 10,000 tons of heavy oil, polluting 400 km of coast of Brittany.
