In 2001,
C & C Technologies Completes Over 5500 Miles Of AUV Survey Lines
|
C &
C Technologies, Inc., a Lafayette, Louisiana, based survey company announced
an outstanding year of accomplishment for its HUGIN 3000 AUV.
Since beginning
commercial operations in January 2001 for BP, C & C has completed over
5500 miles of AUV survey lines. The projects completed with the HUGIN AUV
thus far have been site hazard and preliminary pipeline surveys. Although
the majority of the 2001 AUV surveys were completed for oil and gas companies
with deepwater projects in the Gulf of Mexico, the HUGIN did perform several
government site hazard surveys to study the environmental effects of deepwater
drilling. To date, C & C is still the only company in the world to offer
commercial deepwater AUV survey services.
The HUGIN 3000
AUV is an untethered Autonomous Underwater Vehicle (AUV) equipped with multibeam
swath high resolution bathymetry and imagery, chirp side-scan sonar and
sub-bottom profiler,
C-Nav
differential GPS
integrated with acoustic / inertial navigation and acoustic communications.
The system also includes a proven high seas launch and retrieval system and
is stored in two containers that can be air freighted worldwide. The AUV
is deployed from the mother ship in a free-swimming mode (without umbilical)
for up to 50 hours endurance. It surveys at four knots in water depths up
to 3000 meters before surfacing for refueling of the Aluminum Oxygen fuel
cell. The HUGIN collects seafloor and sub-bottom data on a predefined route,
while sending sub-sampled data back to the mother ship for real-time QC/QA
via "acoustic modem". On-board engineers analyze the real time data and route
accessibility is determined. If the route must be altered, program commands
can be sent to the AUV via the acoustic modem.
Over the past year,
this innovative survey tool has provided clients with exceptionally accurate
data. The improved quality, coupled with the time and cost savings, has given
C & C's clients new options that were never feasible with conventional
deeptow methods.
C & C Technologies
employs over 160 employees and provides worldwide offshore and land surveying
services. For more information on C & C Technologies' AUV services please

| Fishers
Introduce New Cable Tracking System |
Trying to
locate deeply buried power and communication cables has always been a problem.
Many of these cables are buried deep under the ocean floor to prevent snagging
by anchors and fishing gear that could sever or damage them. Before a dredging
operation or underwater construction project can begin it is necessary to
know their exact location. There is not enough metal content in many of the
cables to find them using conventional underwater metal detectors. To solve
this problem JW Fishers has developed a new, low-cost cable tracking
system.
The Cable Tracker
1 system has two parts, the Signal Injector and the Cable Tracker Probe.
The Signal Injector is attached to an exposed part of the cable on land.
A 25 or 1,024 Hz signal is induced into the cable. This signal is quickly
and easily detected using the CT Probe. When searching for power cables it
is not necessary to use the signal injector as the probe can also detect
the 50 or 60 Hz frequency of an AC voltage line. The CT Probe displays its
detection of the cable with both visual and audio outputs. As it approaches
the buried cable, the signal gets stronger in the earphone. At the same time,
the Probes LED bar graph is lighting up more segments indicating increasing
proximity to the cable. When the diver is directly over the cable the signal
will suddenly drop to near zero, called the null spot. If he goes past the
cable, the signal will jump to pull scale again. This method allows the
cables exact position to be very accurately pinpointed. The Cable Tracker
1 system is so effective at finding cables, in many cases the the cable can
located and tracked from a boat on the surface. The system works equally
well out of water and can be used to locate cables on land.
Priced at thousands
less than similar systems being offered, the Cable Tracker 1 is a rugged
reliable system backed by Fishers exclusive 2 year warranty. For more information
on the this system or a color brochure on all of Fishers quality underwater
search products, contact Christopher Combs at JW Fishers Mfg. Inc., 1953

| Measuring
Canada's Complex Currents |
Coastal Ocean
Associates (COA), Canada, and Fugro GEOS Ltd, UK, have teamed to undertake
deepwater measurements off Canada's Atlantic coast to support proposed
exploration drilling. The programme is for PanCanadian Energy Corporation
and Kerr-McGee Offshore Canada Ltd.
COA and Fugro GEOS
have installed an oceanographic mooring in 2000m of water on the Scotian
Slope, about 150 miles south of Halifax, Nova Scotia. It comprises a suite
of nine instruments (two RD Instruments' acoustic Doppler current profilers
and seven Aanderaa recording current meters) measuring current speed and
direction as well as sea temperature. The instruments are collecting data
for nine months over the harshest period of the year in advance of proposed
drilling operations.
When the first
data from the mooring were recovered, COA's Bruce Batstone explained their
significance: "The region is not well known and is expected to be
oceanographically complex due to interaction between the Labrador Current,
Gulf Stream eddies and the Denmark Overflow. Our preliminary analysis shows
the instruments have captured several important phenomena, including the
effects of Hurricane Karen which passed directly over the mooring."
The mooring was
designed to complement concurrent Scotian Slope measurements undertaken by
Canada's Department of Fisheries and Oceans (DFO) about 120 miles to the
east-north-east. The DFO mooring is the first to make measurements on the
'Halifax Line', an oceanographic survey line running south-east out from
Halifax, have been extended into 2000m of water. Together, the two moorings
will provide a unique dataset covering this dynamic area of the Scotian
Slope.
The combination
of COA and Fugro GEOS builds on both parties' strengths and expertise to
provide a high-quality service tailored to meet the clients' needs offshore
Nova Scotia. After collecting the data, the team will analyse them to develop
extreme and normal operating criteria in support of Drilling Plan Applications
for the neighbouring prospects.
COA is a Nova Scotian
oceanographic company with extensive experience on the continental shelf
of Atlantic Canada. As well as providing local logistical and procurement
assistance to meet the rapid mobilisation requirement set by the clients,
it supplies personnel for field operations and for the analysis and reporting
of data.
Fugro GEOS has
extensive experience in the design and deployment of moorings in deep and
ultra-deep waters and is providing the mooring instrumentation as well as
personnel for field operations. Fugro GEOS also works closely with COA on
the data quality control and technical review aspects required by the
project.

| Leica
Geosystems Offers RTK Integrity Monitoring With System 500 GPS Surveying
Receivers |
Leica Geosystems
is now offering CheckMate automatic integrity monitoring with the System
500 series GPS surveying receivers.
CheckMate provides
automatic, continuous real-time kinematic (RTK) integrity monitoring for
99.9% reliability in centimeter-level accuracy GPS surveying.
With CheckMate,
the System 500 continually calculates two separate sets of RTK ambiguities.
By comparing the two, the system ensures that the correct ambiguity solutions
are always being applied. Whenever it detects a disagreement between the
two ambiguity sets, it sounds an audible alarm, displays a visual message
and automatically reverts to precise differential code positioning while
it restarts the ambiguity search routine from the beginning.
"In operation,
CheckMate resolves ambiguities on the fly twice, performs a statistical analysis,
computes the coordinates of the rover and maintains 99.9% reliability for
centimeter-level accuracy," said Hugh Baertlein, vice president for survey
products in North America for Leica Geosystems. "And it does all this in
less than ten seconds."
Baertlein said
that Leica is offering special promotional programs to introduce System 500
with CheckMate to the North American market, including 2.99% financing with
no payments and no interest for 12 months, a GPS receiver trade-in credit
and a $2,500 discount on the purchase of a Leica TCRA1102 robotic total station
when buying a System 500.
Since its initial
introduction in 1999, Leica's System 500 has established the industry benchmark
for high-precision GPS surveying. System 500 products provide efficient
cost-effective single- and dual-frequency real-time solutions for a wide
range of surveying applications.
Leica Geosystems,
with worldwide headquarters in Heerbrugg, Switzerland, develops, manufactures
and markets systems for surveying, mapping and position determination. The
