The
DW 2000 submersible is one-man tetherless submersible
capable of working in depths up to 2000 fsw.As a state-of-the-art submersible
it addresses many of the industry's previous evolutions. Submersible
pilots in the past have been constrained to only piloting the vehicle
and monitoring his systems, which are critical tasks. DW 2000
operators can be alleviated from a number of these tasks due
to technology, modernization and the inherent ergonomic design of this
particular vehicle. In this design the pilot is seated upright, the
view port is a 25" hemispherical dome. The pilot can enter desired
depth and heading data into the PLC (Programmable Logic Controller )and
Instruct the PLC to maintain that course, depth and heading. The PLC
will continue to perform that function until cancelled by the pilot.
The versatility of the PLC along with the ancillary computer also allows
for other capabilities such as acoustic electronic communication of
critical operational information with the surface support vessel.
The
submersible is outfitted with a six-function manipulator, which is powered
and driven by onboard 2200 psi hydraulic system with, 2 spare functions
for auxiliary equipment. A 3" hydraulic cutter capable of cutting
3" steel stock or other materials can be quickly adapted. Additional
hydraulic tooling is easily integrated such as water jets, suctions,
and guillotines.
If
necessary, an additional manipulator can be installed for specific dexterity
requirements. The DW 2000 sub because of its easily
varied payload is an excellent platform for various types of electronic
equipment. The vehicle's standard configuration includes digital video
recording at 550 TVL with time and date stamps, laser scaling, short
and long-range sonar, cathodic potential meters, conductivity, temperature,
and depth ("CTD") meter, which is synchronized with video
recordings, and acoustic telemetry modems, which are used for the transfer
of data between the submersible and the surface vessel. Additional electronic
equipment is easily integrated such as survey grade echo sounders, magnetometers
and many others.
All
onboard electronics are integrated into the onboard 333Mhz Pentium based
computer, which is also controlled by the pilot, independent of the
submersibles PLC. All of these components can be controlled from the
surface vessel, through the acoustic telemetry modem.

Support Components
The
DW 2000 deployment and recovery systems, as well as
on-board communications and acoustic navigation, have been developed
with a purpose built goal in mind - practical and safe operations.
An
A-frame was developed with an hydraulic cursor index integrated to it,
as the primary launch and recovery system for the submersibles. The
index was designed around the DW2000 specifically and
employs a dampening disc-brake system for fore and aft movement.
The
complete system has been developed to mobilize as a spread and is housed
within three standard 20 ft. containers for transportation. Offshore
configuration is based on two side-by-side 20-foot containers, which
serve as hangers and support shop space for the submersibles. These
hangers are set with roll-up doors and are internally connected to each
other during operations. The internal components to the shop space include
the following:
· Air conditioning/heaters
· Deep-cell battery chargers
· High pressure air, low pressure air
· High pressure O2, with Haskel pump
· Electronics repair station with O-Scope
· Complete submersibles spares and backup for spares (rebuild
kits)
