Titanic explorer ‘to dispatch deep-water robots to conserve the wreck’

Small submarines carrying high-paying tourists are also accused of acelerating
the damage by landing on the wreck – a claim strongly denied by expedition
operators.

The wreck will also come under the protection of the United Nations cultural
agency Unesco after the 100th anniversary of its sinking on Saturday [April
15th].

Underwater robots that would clean the ship’s hull and coat it with protective
anti-fouling paint have already been used to treat the hulls of oil tankers.

“When I first came to the ship in 1985, I saw original anti-fouling paint
on the bottom and no corrosion there,”
he told National Geographic News.

“It works, but obviously they didn’t think they’d need to paint the whole
ship with anti-fouling paint.”

He said the technique was needed “so the hull doesn’t splay open and
expose the highly preserved interior with its precious contents”.

Mr Ballard also proposes robot be used as “sentries” to monitor the
visits by tourist submersibles that he is convinced have damaged the wreck.
The Titanic is “being killed by love”, he said last week.

Describing the wreck as “under siege” by natural forces, careless
visitors and rogue salvage operators, he outlines his fears that it will not
survive another 100 years in Save the Titanic, a documentary to be broadcast
on the National Geographic cable channel this week.

But Rob McCallum, the general manager of Deep Ocean Expeditions which will
this summer run a $60,000-a-head cruise and submarine trip to the site, said
it was “nonsense” to suggest that the $50 million submersibles
were knocking into the wreck.

He said the vessels effectively “hovered” weightlessly while the
tourists looked at the remains. “They are delicate, so a pilot who
‘drove around bashing into things’ would probably come to grief pretty
quickly,” he told The Daly Telegraph.

“The biggest fear any sub pilot has is entanglement, so they keep away
from the wreck and usually face towards it so that they can keep an eye on
it so as to gauge relative position and the current.”

He said the Titanic was deteriorating because it is a metal ship that has been
lying in the ocean for 100 years rather than because of the occasional visit
by a small tourist submarine.

In what are effectively unpoliced waters, there are also fears that
unscrupulous salvage teams with small remotely operated underwater vehicles
are plundering the site.

Sen John Kerry recently introduced a bill into the US Congress designed to
toughen up protection of the site.

James Delgado, chief of the maritime heritage office at the National Oceanic
and Atmospheric Administration said: “The Titanic can be a model for
how humanity treats the world’s underwater cultural heritage. But we cannot
do nothing.”
