Oceanic Sirius
Clean-Design High-Capacity 3D Seismic Vessel
The M/V Oceanic Sirius was launched in 2011 as a purpose-built high-capacity seismic vessel,
designed and built to CGGVeritas technical specifications and certified according to IMO code
for Special Purpose Ships (SPS) (70 persons). The Ulstein X-BOW ® design provides excellent
hydrodynamic performance with reduced surging and turbulence. The hull, rudders and propellers
are optimized for seismic towing operations at 4.5/5.0 knots, leading to reduced noise and fuel
consumption and lower CO 2 emissions.
This vessel is one of the most powerful seismic vessels afloat with a static bollard pull of 190
tons, making her ideally suited for acquisition of large 3D projects. The 20-streamer winches,
carrying Sercel Sentinel ® solid streamers and 20 tow points, give the Sirius the flexibility to
employ a variety of acquisition geometries.
The Oceanic Sirius has DNV-CLEAN notation for the lowest environmental impact and a Green
Passport (mapping and overview of materials and chemicals in vessel from cradle to grave). She
exceeds the highest environmental standards, having a complete Water Ballast Treatment system
installed.
The Oceanic Sirius is an SX120 hull form designed by Ulstein with a focus
on environment, low emissions and comfort for the crew. Her DNV-CLEAN
notation means that she is among the most environmentally sound
vessels afloat, with double hull, low-emission diesel-electric engines, an
advanced water ballast treatment system, garbage incinerators, a fuel
overflow tank system and drip trays, etc.
The vessel is fitted with electrical propulsion allowing smooth control
of speed during seismic acquisition. Four generators provide power and
propulsion redundancy and use low-emission fuel. Her high fuel capacity
and ability to refuel at sea allows the vessel to remain at sea for
unlimited periods, increasing production. The Sirius has a cruising speed
of 17 knots which reduces mobilization time.

Get to Know Our SeisAble Benefits
The Seismic Instrument Room is located at top aft and is designed with
an ergonomic platform for human well-being in the work place. The
seismic instrumentation consists of multiple Sercel Seal 428® recording
systems and Sercel Sentinel 2Hz solid digital streamers. The Sirius is
equipped with Sercel Nautilus®, the leading solution for full acoustic
bracing, streamer steering and depth control for 3D and 4D acquisition.
The seismic sources on the vessel consist of tuned arrays of G-Gun II®
air guns controlled by Seamap Gunlink 4000® gun controllers.
The CGGVeritas proprietary geovation seismic data processing system is
integrated with the acquisition systems for onboard quality control and
advanced high-technology data processing. ‘Fast-track’ final products
can be produced onboard shortly after completion of acquisition. Quality
control products produced in real time include brute stacks, signal-noise
ratio analyses and near-trace cube displays.
