Martin Verhoef runs a lifeboat company called the Verhoef
Aluminum Scheepsbouw, located in the Netherlands. It
specializes in the totally enclosed, free-fall lifeboat,
which is designed to get passengers quickly and safely away
from danger, from sinking ships to burning off-shore oil
rigs. Verhoef has had an interest in lifeboats since he was
a child, when his father ran the same company.
NOVA: Tell us about your father's childhood and his
interest in ships.
Verhoef: Well, I remember from my father that he kept
track of all the ship disasters during his childhood. And he
had a kind of driving force to know exactly what was going on.
Funnily enough, later on he used all that information by
building the safest lifeboats ever designed.
NOVA: When did he start his company?
Verhoef: In 1941. At first he just made pots and pans
of aluminum. But, shortly after World War II he designed the
first aluminum lifeboats, which were sold to a Norwegian ship
owner. During the following years, he built up quite a
reputation. Worldwide, people knew who we were. Because of
this reputation we came in contact with a Dutch ship owner,
who asked us to design a lifeboat that was safer than anything
ever built before. He had escaped twice from a shipwreck, and
he didn't want to go for a third time.
So my father looked at all the areas that needed improvement.
The first one, of course, was the need to get quickly away
from the ship as safely as possible. Traditionally a lifeboat
is launched by two wires. But doing this in rough weather
conditions is very dangerous. That's why he decided to release
the lifeboat from the stern of the ship by means of a cradle.
The advantage is that you are only depending on gravity. It's
no longer a case of: Are the wires strong enough? Will the
winds cooperate? The release mechanism has to be operated, and
that's it. Gravity does the job. Once this boat is launched,
it immediately clears the area into the safe area. And it
doesn't take more than a few seconds.

ground-breaking lifeboat engineer.

NOVA: What other safety devices did your father come up
with?
Verhoef: It was quite a revolution when my father
designed this lifeboat in the early 1960s, because you have to
bear in mind that in those days, lifeboats were still open.
Now, to launch an open lifeboat is quite a risky job,
especially if you have high seas and stormy conditions. This
lifeboat was entirely covered, so that people were no longer
exposed to environmental conditions, like a fire or a storm.
The free-fall lifeboat met the toughest requirements you can
think of.
So we were really hoping that we would get orders for more
free-fall lifeboats. But the opposite was true. We had to wait
20 more years. When my father tried to promote the use of the
free-fall lifeboat, he became very disappointed. People
discussed the price and the use of it. He was very committed
to market his free-fall lifeboat, because he knew that people
could be saved at sea if there was a need for it. I remember
that after a discussion with a ship owner, who was almost
heading toward the use of free-fall lifeboats, and in the end
turned him down, he said, "You will mark my words, you'll need
another disaster before you go ahead with this free-fall
lifeboat." What we did in the meantime, especially my father,
was to try to improve everything about the lifeboat that we
had previously made in 1960.

Early tests on this life boat demonstrated that it
was self-righting and reliable.
|
NOVA: What else did you improve?
Verhoef: After 25 years of improvement, my father
eventually came up with a good design. It's launched quickly,
and it can be launched even from high heights, like 80 feet or
more. It maintains its forward motion purely because of its
special sharp-shaped design. So, within seconds, you are at
least 330 feet away from the [oil] platform. It's
self-righting, so that no matter what condition the boat
enters the water in, it always rights itself automatically. At
that time, legislation didn't require anything. So it was a
revolution for this free-fall lifeboat to be self-righting in
all circumstances.
Verhoef's lifeboat could even withstand
flames—the temperature inside this boat only
reached 85° F throughout its test by fire.

In 1984, we had nearly completed our mission. But still we had
to cover one more aspect, and that was that it should
withstand high temperatures. If there is an oil fire around
the platform, the boat still has to be launched, and it should
protect all the occupants in the lifeboat itself. So behind
our factory we dug a big hole and poured in about 1,300
gallons of kerosene purely to keep the fire burning for at
least 10 minutes. And we put our aluminum lifeboat inside the
fire tank. Every 10 seconds we measured the temperature, and
we were very pleased to see that it was only 85°F, so, it
would be just like a sunny day while you were rescued from a
fire.
During a fire you can't open the windows, of course, so that's
why we also have our own air supply inside the lifeboat. So
besides the engine, you have the water spray system, but you
also have the air supply. And it is enough for 10 minutes of
sailing at a speed of six knots.
NOVA: When did you first start supplying lifeboats for
oil platforms?
Verhoef: I would say early 1980s. It's interesting to
note that when oil platforms were developed, nobody knew what
kind of safety systems would be needed. They simply went to
the shipping inspectors and said, "Well, aboard ships we're
using this kind of lifeboat. So let's put those similar
lifeboats on the platform." In many locations in the world,
that's not a bad idea. When the sea is calm, and there are no
frozen or icy conditions, then it's no problem to jump into
the water. But in other places there are very, very difficult
environmental conditions for which it's very dangerous to use
conventional systems. When it's very cold with high winds, a
lot of waves and so on, it's very dangerous. You simply need
another kind of evacuation system. So our newer boats can be
launched from high heights like 100 feet, without having high
acceleration forces.
NOVA: When did you start getting customers for these
free-fall lifeboats for oil platforms?
Verhoef: Sadly enough, the Piper Alpha disaster
really led to a big breakthrough for our free-fall lifeboats.
[In 1988, the Piper Alpha oil platform exploded in the
North Sea, and many oil workers were killed.] From that point
on, people were aware that there was an immediate need for
safer evacuation systems, an evacuation system that could be
used from high heights like 100 feet and over.

NOVA: Paint a picture of what happens in an emergency.
Verhoef: In the case of an emergency, people are
trained to board a lifeboat as quickly as possible. These
aluminum free-fall lifeboats are designed to get 45 people
safely away from any hazards, like a platform or a ship. So
they simply go to the far end of the boat, take their seat,
and when they all do it simultaneously the aisle is completely
free for the new range of people. Using this procedure, it
only takes three minutes to board the lifeboat completely.
The boat is released hydraulically. One person could easily do
it, but we have chosen to have it be done by two people in
order to avoid the possibility this lifeboat is launched by
someone who simply wants to get away from the platform. So one
person operates the launching pump, and the second one has to
simultaneously operate the launching valve. By doing this
together, the hydraulic pressure is built up and the release
mechanism is activated.

It's very important that as the boat leaves the platform
everybody is well prepared for it. We have red lights inside
the lifeboat in order to tell people that the release
mechanism has been activated, and within a few seconds after
that, the boat will drop into the sea, and within five to six
seconds it's already 330 feet away from the platform.
NOVA: Do you supply any lifeboats to passenger ships,
such as cruise ships?
Verhoef: No, not at all. The design of today's cruise
ships does not allow the mounting of a free-fall lifeboat at
the stern of the ship. There are so many people on board that
you would need to have free-fall lifeboats projected on each
ship's side. That takes a lot of space and has a high cost.
Today, still, safety is as high as people want to pay.
NOVA: Or until another accident happens.
Verhoef: Yes. I think that a tragedy like the
Titanic could be repeated. The majority of people on
board ships are there for the first time. They don't know how
to react in a panic situation. There are so many open ends
that it's still dangerous.
Freefall lifeboats can now be mounted on other ships.

NOVA: Do you think that any of the innovations your
company has come up with for lifeboats are applicable to other
escape technologies?
Verhoef: The next challenge will be a launching system
for lifeboats from an airplane. We found that a free-fall
lifeboat on board could be very valuable in some areas when
the wind is too high and the waves are too high. So, by simply
dropping a free-fall lifeboat out of the plane, you could
offer more safety, more assistance.
NOVA: From what height could you safely drop a
free-fall lifeboat?
Verhoef: Well, presently we're doing drops over 330
feet using a parachute. The work takes a long time. We are
cooperating with Clemson University in South Carolina, but
everything depends on financial support. If we succeed in
developing such a system, there will only be a very small
market for it. We've talked to NASA, and they've been very
interested. Although I must admit that every time the budgets
are cut, things slow down.
NOVA: Is it inevitable that we have to put a financial
limit on how much we're willing to spend to reduce risk? Do
companies wind up having to put a value on people's lives?
Verhoef: Well, I think at least one of our duties in
trying to achieve the best kind of evacuation system is to
target yourself to almost zero risk. Once it appears that it's
possible to meet, then the industry, engineers, and so on,
they are in a way challenged to see whether they can meet the
level in spite of the fact that there is no real financial
support for anything like that.

Freefall lifeboats were installed on the
Piper Bravo platform.

NOVA: What advice would you give a young person who is
interested in going into a similar line of work?
Verhoef: I would always try to get as much information
as you can get today in the way of casualties and so
on—to get a clear picture of what the needs are for a
new system. If you want to do something that you can market,
to convince people that it's much safer, then at least you
have to have the knowledge of what kind of casualties happened
in the past. It's also very important that you listen to the
operators, to the people who want to use the evacuation
system. You can only do that if you have been on board ships
for a couple of weeks or on an oil platform. You have to have
the connection with reality. Otherwise you design something
that is of no end use.
