iXSea - is a research partner of the Mayflower 400 autonomous ship project

iXblue navigation technology was selected by ProMare, to provide accurate navigation capability to one of the world's first autonomous ships, designed to cross the Atlantic: the Mayflower Autonomous Ship (MAS).

This fully autonomous and unmanned ship is set to cross the Atlantic in April 2021, to commemorate the fourth centenary of the original Mayflower voyage. iXSea is listed as a research partner.

IXSEA SAS is a leading solution provider to scientific, offshore, defence & space customers with a range of innovative systems & solutions to meet their individual navigation, positioning, imagery, moorings and survey requirements.

Their products range includes sub sea navigation & tracking, acoustic locators, seabed mapping-REA, land navigation & orientation.

IXSEA SAS is an efficient manufacturer of Seabed Mapping-REA. IXSEA SAS’s seabed mapping-REA includes MAGIS, ECHOES 1500, ECHOES 3500, ECHOES 10000, DELPH MAG LOCATOR, DELPH SEISMIC and DELPH SONAR. IXSEA SAS’s seabed mapping-REA is Prepared as per national and international standards.

OCTANS is a subsea survey-grade gyrocompass and complete motion sensor for water depths up to 3,000m. Based on FOG technology it outputs heading, roll, pitch, surge, sway and acceleration. OCTANS 3000 can be easily upgraded to full INS mode (i.e. ROVINS).

FEATURES

• Complete gyrocompass and motion sensor
• Fiber Optic Gyroscope (FOG), unique strap-downtechnology
• Titanium construction
• Small, portable plug and play system
• Optional full featured Inertial Navigation System

BENEFITS

• High-performance real-time outputs of true heading, roll,pitch, heave, surge, sway, acceleration and rate of turn

• No spinning element hence maintenance free
• Lightweight corrosion free housing for water depth up to 3,000 m
• Easy to integrate and interface, saves valuable mobilisation time
• Obtain INS-class system with simple software upgrade

APPLICATIONS

• ROV & offshore survey
• Multibeam and sonar motion reference
• Dredging
• Marine construction

3D FISHERY SONAR SEAPIX

iXblue has implemented major technical evolutions to its 3D volume Sonar for fishery use, including new data processing, new graphical user interface and the use of a multi-head system.

Christophe Corbières is quoted as saying: “This work initiated in 2019, is a major step in the development of the SeapiX range in high value fisheries, where the quantitative and qualitative assessment of stocks and their management is fundamental to comply with regulations and improve vessel's economic and operational efficiency.”

SeapiX now produces up to 8,000 definition points on its 512 beams (4 M of data), i.e. 50 times more data processed and displayed. Previously invisible on the fishing sonars, the aggregation modes of the shoals are now discriminated on the screen and the skipper can assess the "real" concentration/dispersion of individual fish in a shoal, which is also a new field of study for the scientific community.

SeapiX is a system made up of "Transducer arrays" forming a set of 1 to 3 SAU transducers to meet the highest requirements of pelagic and demersal vessels, for example using a downward SAU for near-bottom trawling and a lateral SAU to assess near-surface biomass and optimize purse seine catches. Each SAU transducer covering a water volume of 120°x120°, a set of 2 to 3 SAU transducers offer an exhaustive analysis of the entire volume of water (at 7 cm radial resolution with calibrated TS split beam calculation) within a radius of 400m all around the vessel.

Its unique features and specifications on the market make SeapiX an essential tool for biomass discrimination and selectivity, allowing the estimation of each fishing situation and the development of real catch strategies. The optimization of the profitability of the vessels observed through the practice of targeted and rapid catches guarantees the adaptability of the vessels in a context of a constantly evolving fishing market.
