Oil spill detection, response and recovery
Early detection
Early detection and the ability to mount an emergency response
are essential should an oil spill occur. Oil spills are costly to the
environment and the maritime industry, so oil spill prevention,
detection and recovery are paramount.
Having dedicated equipment permanently installed on your
vessel that will allow you to accelerate the clean-up operation
and contain the contaminated area is a necessity. The Simrad
ARGUS Radar Oil Spill Detection application is a must have, and
this is a simple add-on to our standard type approved IMO/SOLAS
navigational radar. The advanced hardware video processing
function enables the detection and tracking of oil slicks.
On-board with Simrad ARGUS
The Simrad Argus Oil Spill Detection application works by receiving
and processing signals in real-time from on-board transceivers.
The water surface is usually dampened when it is contaminated
by oil, so the backscatter of microwave radiation from these waves
is unlike the rest of the sea. The radar is then able to highlight the
dampening of the reflected microwave radiation on the radar
display, thus calculating the size, position and drift (speed and
course) of the oil spill. We let you see inside the oil spill!
Looking inside the oil slick with your standard
navigational radar
Ships in regular operations can use the primary radar set as a
traditional instrument for navigation, and the secondary radar
display (interfaced to the primary radar) switched over to the
advanced function of Oil Spill Detection. We are among the first
companies in the world to provide an oil detection application
working in parallel with its IMO/SOLAS ARPA navigational radar.
From the ship owners’ point of view, the most important benefit is
the reduced maintenance costs in terms of installation, service and
spare parts. In addition, the officers on watch don’t have to learn a
new operating system, because the OSD functionality is part of the
standard navigational radar system with the same user interface.
The Simrad ARGUS Oil Spill Detection radar operates on the same
hardware (not PC based) approved by the Federal Maritime and
Hydrographic Agency in Germany (BSH), and is compliant with the
European Maritime Directive (MED) and United Stated Coast Guard
regulations. In a combined and integrated navigation and oil spill
response and management bridge system, the stress of the officers
on duty is drastically reduced by operating on the same userfriendly
graphical man-machine interface.
Long heritage and global support
With over 60 years at the forefront of product innovation, we are
one of the world’s most recognised brands in the field of marine
electronics. This heritage provides a platform from which some of
the most innovative products are engineered. Our OSD application
is one that you can depend on to improve oil spill response
capabilities, and should the need arise, our global service network
of support engineers located in over 50 key ports around the world
will deliver first class on-board service.

How the Argus Oil Spill Detection software works
How it works
In general, the operation of the marine radar is based on the
physical phenomenon of backwards “scattering” of microwave
radiation. When the microwave radiation waves strike an object,
they are reflected in all directions. The signal is also partially
radiated back towards the direction of origin (backscattering),
generating an echo on the radar display. The wind causes the
regular rise and fall of the water level: the sea waves.
The presentation on the navigational radar screen is affected by
the presence of the waves. The waves seen by a radar appear as
an immeasurable amount of reflective objects that radiate back
microwave energy in a completely chaotic and incoherent way
over 360 degrees for several miles. The navigational radar has
countermeasures to reduce this disturbance caused by waves and
makes visible the possible targets.
For the Oil Spill Detection functionality it is vice versa. Echoes
from particular waves are required. Ripples, called capillary waves,
appear on smooth water when the wind blows due to the friction
of air flowing over the sea surface.
The echoes from the sea surface, in terms of microwave radiation,
meet the law of the surface reflectivity.
The microwave radiation reflectivity
depends on the angle of incidence, the
roughness and the dielectric constant
properties of the sea surface. The
suppression of the capillary waves by oil
viscosity reduces the surface roughness.
The different dielectric constant of the oil
results in less radar backscatter.
The returning signal from an area contaminated by oil is slightly
dampened by both of these factors working simultaneously.
The excellent capability of the Simrad Argus Oil Spill Detection
radar, thanks to an advanced real-time signal processing, is able to
highlight the dampening of the reflected microwave radiation on
the radar display.
Vertical Polarization Antennas
When discussing microwave energy propagation and scattering,
the polarization of the radiation is an important property.
Although imagery in both vertical and horizontal polarizations
can be used for slick detection, the vertical imagery is preferred
for dedicated oil spill radar sensors. In general, it offers a stronger
clutter background than other polarization choices, generating an
improved contrast with the oil contaminated areas.
However, in spite of the fact that vertical polarizations are more
sensitive than horizontal for slick detection, there are only
disadvantages in their use for navigational radars.
Simrad Argus OSD display is available in three different configurations to suit any vessel:
The deck configuration provides an
optional display deck stand which can
also house the electronic cabinet.
Two different options available :
• Desk-Top Cabinet for 26“ with Pedestal
• Desk-Top Cabinet for 23“ / Adapter
Frame kit for 19” Monitor / Pedestal
The modular configuration with
monitor, keyboard and ARPA electronic
cabinet supplied as three separate
modules which can be flush mounted
into the bridge console to the customers´
preference.
The table top configuration where
the monitor and key-board are housed
into an ergonomic console while the
electronics are contained in a separate
bulkhead mounted cabinet.
