Since 1995 the private research team “Search & Recovery” is
concerned with the
search, location and recovery of sunken objects
maximum depth of 650 feet. We have developed a comprehensive concept
during this period for dealing in full with all the complex issues
in the SEARCH, LOCATION and RECOVERY of sunken objects. What is more
we have implemented our concept with dramatic success in practice.
This complete solution, with the equipment we have developed and the
know-how we have acquired is technically mature and has been tried
and tested proving its great value in the many projects we have
carried out with complete success.
are not to be regarded as a commercial operation, however, nor is
our interest in using these pages to acquire valuable new contracts.
This entire exciting field itself is what fills us with enthusiasm.
Our prime motivation is the challenge of the future projects
themselves that we may be called on to handle.
core element in our equipment is an underwater towed video system we
developed ourselves; it is fitted with a camera unit, 4
searchlights, a drive system and a 2-axis gripper mechanism. This
camera robot is attached to a special cable and is towed along the
bottom of the lake by a workboat. This visual search method is
suitable only for relatively small search areas because of the low
visibility. Our experience in searching very large areas with
side-scan sonar technology has been excellent. The workboat is GPS
navigated and in the course of this a freely defined search area is
traversed using modular grid software as a reference. When the
sought object appears on the monitor the coordinates and the current
depth of the find location are recorded and saved using GPS and PC
software. It is at this point that the search process itself is
concluded and the towed video system is now fitted with our gripper
module. The search object is then approached for a second time
around this approach using the saved GPS coordinates. The gripper
clutches the sunken object on a suitable hold point. When a direct
recovery is not now possible due to the weight of the object, the
towing cable is fully tightened and a second guideline cable is
anchored directly adjacent to the found object. The camera robot can
now use this guideline cable to dive straight down to the sunken
object whenever required and with no need for divers, by attaching a
strong cable using a specially developed snap-action mechanism.
Should it not be possible to attach this cable by remote control
then divers can be used to deal with this task. They can of course,
readily reach the object simply by following the guideline cable
hope you enjoy your journey of exploration in our homepage as you
read about our achievements and we very much look forward to hearing
your feedback. Contact us by e-mail:
firstname.lastname@example.org, we also look forward to
engaging in a specialist discussion of one kind or another. A joint
project of the kind we are interested in could well develop from
beginnings such as these.
