Bigger Cable Lay Projects• Longer ‘intercontinental’ lay distances• Deeper water - top tensions to 100t+
Nexans Aurora• Recently launched• 75t top tension; Ø10m capstan• 10,000t payload capacity; 200+km• Intelligent control system
\
Advances on Inter Array CLV Technology
Van Oord ‘CLV 3’
• State of the art Inter Array CLV: launch 2023: succeeds Nexus
• 12 months concept design : Van Oord experience
• 2 carousels total 8,000t : innovative space payload utilisation
• The largest IAC vessel to date, HVDC capable
• Intelligent control system: speed, reliability, safety
\
Floating Wind
• Very early stage - conceptual• Consensus is will be more prolific then fixed• Deepwater regions; Japan, Korea, Pacific
Challenges – Cable Lay
• Dynamic cables• Bouyancy modules, rigid connectors, joints
❖ Do not lend themselves to horizontal lay over chute• Mooring chain
❖ Significant quantities, more than FPSO project
• Can it be as efficient as fixed bottom installation?

3 I
Aurora : Integrated cable design and installation operations
Designed with 70 years experience in
installation of submarine power cables
Issue:
• High tensile load → high friction forces
• Tension + Bending + friction →poor combination for cable internals
• Worse for single core cables →typically in deepwaterapplications.
Solutions:
• 75 ton cable capstan OD 10m
• Ø10m overboarding wheels, 75t capacity, instrumented for load readout.
• 75t Active heave compensated constant tension winches
4 I
Aurora : Deepwater
Aurora: Landfall operations
Issues:
• Main risk driver → for cable, schedule, permits
• Shallow Seabed topography → long pull-in operations
• Through HDD → added complexity
• Weather sensitive → short and efficient operations
Solution:
• 5,5m draft → 7,5m water depth
• 8 x Integrated high capacity workboats
• Cradle and launch systems
• Dedicated float handling system with man riding baskets.

1 GW OF OFFSHORE WIND REQUIRES:
o Submarine Transmission cable (AC or DC)
o Land Transmission Cable (AC or DC)
o Inter-Array cables (MV 33 or 66kV)
o Installation for all
FACTORS THAT INCREASE CABLE MARKET:
o Distance from shore
o German legislation

Champion in the energy transition
LONGER CABLE CONNECTIONS
able to cover >200 km length to serve
ultra long interconnections
HIGHER DEPTS UP TO 3000m
thanks the combination of new
cable technology (synthetic armour which
is 30% lighter) & new state of the art cable
laying vessel Leonardo da Vinci

GRUISSANFLOATING WIND FARM
FOLLOWING THE KINCARDINE AND PROVENCE GRAND LARGE
PROJECTS, PRYSMIAN FURTHER CONSOLIDATES ITS POSITION
IN THE FLOATING OFFSHORE WIND MARKET,
by providing one 66 kV EPR three-core export submarine cable
for a total of 25 km and attached another 66 kV EPR submarine
dynamic cable for about 1 km connecting the shore to a floating
sub-station and additional 3 km of land cable 66 kV XLPE.
Sofia Project involves more than 440 km of ±320 kV
submarine HVDC export cables with XLPE insulation,
and 15 km of ±320 kV land cables with P-Laser.
IT WILL BE THE FIRST OFFSHORE WIND PROJECT
TO USE THE BRAND-NEW LEONARDO DA VINCI.
