Seaeye ROV Gets Pipeline Survey Spread
A full pipeline
survey spread has been fitted to a Saab Seaeye's
(Fareham, England) Panther XT Plus ROV.
ROVOP Ltd. (Aberdeen, Scotland) ordered the first two Panther XT
Plus ROVs with a pipeline survey package, after conducting trials with
the system in May.
The survey spread installed on the Panther XT Plus includes a Teledyne
TSS (Watford, England) pipe tracker; two Reson
A/S (Slangerup, Denmark) SeaBat 7125 multibeam sonars with
dual-frequency operation; a Sonardyne (Yateley, England) Lodestar
navigation system, a Doppler velocity log, camera booms and wheeled
The pipeline survey system also has two four- and seven-function
Schilling Robotics LLC's (Davis, California) Orion manipulators and a
contact cathodic protection measurement system.
The Panther XT Plus comes with 10 thrusters, eight giving horizontal
Saab Seaeye said it was able to incorporate the survey spread on the
ROV by creating a vehicle design with more space for tooling,
increasing the number of data interfaces (including a gigabit Ethernet
multiplexer serial data interface) and power supplies, and improving
the hydraulic system.
The main benefit for operators is savings in the cost
of ownership due to a smaller and lighter vehicle that
needs less deck space and fewer crew, Saab Seaeye said.

Purchases All Assets of ANT's Littoral Glider
(Anchorage, Alaska) purchased last Tuesday all the assets, intellectual
property (two patents and one pending) and technology for the Littoral
Glider from ANT LLC (Anchorage). The manufacturing of the gliders, now
called Exocetus Coastal Gliders, will continue to be based in
Anchorage, at the Exocetus facility.
The glider was developed under funding from the U.S. Office of Naval
Research over a six-year period, during which 15 gliders were delivered
to the U.S. Navy, Exocetus said.
ANT version of the glider is 6 feet long, with a diameter of 12.75
inches and a weight of 265 pounds. It can operate from 33 to 656 feet
depth and has a horizontal velocity of 2 knots, with the ability
to station keep in 2-knot current. The GPS is accurate to 300
feet. Mission duration ranges from 15 days on rechargeable power to 30
days on primary power. Communications
satellite, freewave and acoustic modem.
The initial primary market for the Coastal Gliders is coastal regions
where hypoxia is prevalent during the warm months of the year. There
are more than 200 regions of eutrophication and hypoxia throughout the
world's coastal areas.
Another near-term market for the glider will be research institutes
studying ocean acidification.

Romney Criticizes President Obama's Navy Fleet
candidate Mitt Romney equated the
present size of the U.S. Navy fleet to 1916 levels during a speech at
the Virginia Military Institute last Monday, adding that he plans to
build 15 ships per year, including three submarines. He would also
permanently deploy an aircraft carrier in the Persian Gulf and the
Eastern Mediterranean, The Wall
Street Journal reported.
The Navy had
245 ships in 1916, but the ships included outdated vessels, e.g.,
monitors and gunboats, according to The
Washington Post. The Navy now
has larger ships, such as aircraft carriers, and nuclear-powered and
missile submarines, which means Romney’s remark is "an
apples-and-oranges comparison," the paper wrote.
Between 2003 and 2011,
the number of ships fluctuated between a high of 297 and a low of 278.
The low occurred in 2007 under George W. Bush. Under President Barack
Obama, the number of ships has risen slightly, CNN reported.
Navy plan is to build 34 ships over the next four years, including
seven submarines, as part of its goal to reach at least 300 ships by
Under the best-case scenario of Romney's proposal, the Navy would
end up with about as many ships as it had in 2000, which is not much
better than the 1916 fleet size, according to The Washington Post.

Temperature Logger Designed
For Tight Spaces, Long-Term Deployments
RBR Ltd. (Kanata, Canada) introduced last Friday its
smallest temperature logger, the RBRsolo
T. Its size is suitable for applications such as
moorings, boreholes, profiling or towed arrays in
oceanographic, freshwater, coastal or Arctic research.
The single-channel RBRsolo T
is the next generation of the TR-1060 and can be deployed long term and
in harsh environments. Deployments of more than five years are
possible using a 3.6-volt
lithium-thionyl chloride cell battery.
While similar in size to the TR-1060, the RBRsolo T uses a new architecture,
resulting in less power consumption, more memory capacity and
faster download speeds. The data-storage capacity provides memory for
about 30 million samples, with data retention for 20 years.
In its standard calibration, the RBRsolo
T has a measurement range of -5º C to 35º C. It can also be calibrated
from -40º C to 50º C. The device is calibrated to an accuracy of
±0.002º C. The standard thermistor has a time constant of approximately
The housing has a depth rating of 1,700 meters.
The new mechanical design enables easy desiccant placement to mitigate
condensation or risk of damage during battery replacement or data
