AT SEA
A New Balance
Between Pollution
Prevention And
Mitigation
by Captain Okkie Grapow, president,
International Salvage Union
Perhaps the prizes for the most thankless job in the world should go to the people in charge of clean-up operations following a major oil spill. As experts, they will be only
too painfully aware of the severe limitations of
today's clean-up technology. They will know that
oil recovery rates of less than 10 percent are the
norm. Yet they will be surrounded by people with
totally unrealistic expectations of what can and
should be achieved.
With this in mind, one can be forgiven for asking
why the Oil Pollution Act of 1990 (OPA 90) directed
virtually all available resources towards mitiga-
tion measures post-spill, rather than preventive
measures which aim to stop spills from happening
in the first place.
The huge funds made available for clean-up
were allocated without cost-benefit analysis of more
promising preventive strategies. If this analysis
had been done, a proportion of the funds almost
certainly would have been channeled into salvage,
the first line of defense against pollution.
The weakness of
OPA 90 needs to be
put into perspective.
During 1989 to
1992, International
Salvage Union
member salvors at-
tended 40 casualties
involving actual or
threatened pollu-
tion on a major scale.
The main technique
adopted was ship-
to-ship transfer of
cargo, following the
salvage team's ini-
tial action to extin-
guish fires, pump out flooded spaces and make
emergency repairs. Without the salvor's interven-
tion, large spills would have resulted and clean-up
teams (even those well-equipped and resourced)
would have probably picked up 10 percent at best.
It is easy to understand the general reluctance
to face up to the disappointing realities of clean-up.
Salvage, meanwhile, is not the only preventive
option. Other actions on this front include: the
introduction of Total Quality Management sys-
tems; Enhanced Survey; and tougher port state
control. However, all other options have a serious
flaw: they will take years to deliver their benefits.
The shipping industry can't afford to wait for such
improvements. In the 1980s, the numbers of seri-
ous shipping accidents fell. But the trend moved
into reverse over the past three years. The tanker
owner faces an ever-present risk, albeit slight, of
involvement in a spill of catastrophic proportions.
There is an acute need for measures which
promise to be effective in the short-term initiatives
which can deliver an immediate and dramatic
reduction of operational risk.

Salvage is a viable short-term route to signifi-
cant risk reduction, as salvors often transform
a potential pollution disaster into a successful
salvage. However, new initiatives are needed if
an appropriate level of salvage-based protection
is to continue to be available, at round-the-clock
readiness, to defend heavily trafficked areas
and vulnerable shorelines.
Those responsible for drafting OPA 90 may
have overlooked the importance of salvage due
to the simple fact that the salvor's success is
invisible. Fortunately, however, the U.S. au-
thorities now embrace the ISU's first principle,
which is "keep the pollutant in the ship." The
logic behind this approach has prompted a ma-
jor survey of salvage resources in U.S. waters.
The National Response Corp., working with the
U.S. Coast Guard (USCG) and the U.S. Navy
(USN), is in the process of reassessing national
salvage posture, with particular emphasis on
the role of salvors in emergency response and
pollution defense.
Major operations carried out over the past
year underlined the effectiveness of timely sal-
vage response and cargo recovery via ship-to-
ship transfer. These cases included two major
emergencies within the space of four months in
the Malacca Straits.
In September of last year, the Liberian tanker
Nagasaki Spirit and the containership Ocean
Blessing collided in the northern approaches to
the Straits. The 96,000-dwt Nagasaki Spirit
suffered severe structural damage and lost ap-
proximately 12,000 tons of crude oil. There was
also a severe loss of life. Huge fires resulted, but
were eventually overcome by salvors. Later, the
bulk of Nagasaki Spirit's cargo was transferred
to another vessel.
In January this year, the 270,000-dwt Maersk
Navigator and the smaller tanker Sanko Honour
collided in the same area. The first salvage
vessel to arrive at the scene found the Maersk
Navigator a mass of smoke and flames.
After many days of close-quarters firefighting,
the salvors extinguished the fire and safely
transferred around 90 percent of Maersk
Navigator's 250,000-tons of Omani crude to an-
other vessel.
Over the past 15 years, ISU salvors per-
formed more than 2,400 salvage operations;
several hundred involving laden tankers. If
salvors are to continue to provide essential pol-
lution prevention services, there needs to be a
better balance between prevention and mitiga-
tion, and an appropriate reallocation of resources.
• Fleet Age & Human Error
Three P&I studies over the past two
years have confirmed that 60 to 80 percent
of all shipping accidents result from hu-
man error (see related story page 44).
Meanwhile, freight rates remain too low
to trigger newbuilding programs on a scale
extensive enough to produce a younger
world fleet.
The human error and age factors brought
Tecnitas, the Bureau Veritas consultancy
which carried out the first-ever Interna-
tional Salvage Survey in 1992, to the alarm-
ing conclusion that an additional 100 seri-
ous shipping casualties a year can be ex-
pected by 1996.
This belief, that the improvement in
maritime safety visible in the 1980s has
moved into reverse during the 1990s, has
touched a raw nerve in many administra-
tions. In the U.K., for example, the loss of
the Braer in early 1993 resulted in a De-
partment ofTransportation-commissioned
study of emergency towing and salvage
resources available to protect the British
coastline.
In February, a joint industry body, the
Salvage Working Group, published a re-
port calling for greater industry collabora-
tion with governmental and
intergovernmental agencies on salvage-
related issues, including pollution defense.
Within days of the loss of the Braer, EC
Environment and Transport Ministers
gathered to consider the scope for new
initiatives to improve maritime safety and
pollution prevention. A few weeks later,
the European Commission adopted a "Com-
mon Policy on Safe Seas." This calls for
new measures in the areas of emergency
response and salvage cover. Meanwhile,
the International Maritime Organization
declared the improvement of salvage ser-
vices a high priority task under resolution
8 of the Oil Pollution Preparedness, Re-
sponse and Cooperation Convention. The
IMO work will build on the Salvage Work-
ing Group's recommendations.
The industry is also stirring following
publication of the Salvage Working Group
report. A successor body, the Salvage Liai-
son Group, met for the first time in May.
Already, the ISU and BIMCO have agreed
on new model contracts for wet salvage
services, thus fulfilling one of the Salvage
