Chaque vague au large, comptée.

Pilotes, capitaines de port, pêcheurs, surfeurs et ingénieurs côtiers ont tous besoin de connaître les vagues. Des bouées ancrées mesurent la hauteur, la période et la direction des vagues avec le vent et la température de la mer, transmettent toutes les demi-heures par satellite ou réseau cellulaire et conservent les séries sur lesquelles reposent les ouvrages côtiers.

1. Océans · Vagues et bouées côtières

   Everyone at sea needs the waves

   Pilots bringing ships into port, harbour masters, fishers, surfers and coastal engineers all need to know the waves. Forecasts need observations to check them, and coastal designs need decades of records. Moored buoys provide both, if they survive the storms they exist to measure.

2. Ce qui est mesuré

   Height, period and direction

   Motion sensors on the buoy measure wave height, period and direction, and wind, pressure and sea surface temperature sensors measure the conditions around it. A satellite position on every report shows the buoy is still on its mooring. Every instrument keeps its calibration and position with the site record.

   Instruments

   Wave motion sensor · Wind · Pressure · Sea temperature · Position

3. Le nœud de base

   Spectra at sea

   The node computes wave statistics and spectra on the buoy, applies the real-time quality checks for waves, watches its own position for signs of a mooring failure and sends compact reports, shedding non-essential sensors when power runs low in the darkest weeks.

4. Radio et liaisons

   Cellular near port, satellite offshore

   Buoys near ports report over cellular, cheaply and often. Offshore buoys beyond coverage report through a satellite terminal. Reports reach forecasting systems, harbour systems and global marine data centres in their own formats. When one path fails, the other carries the data.

5. Comment ça marche

   From a swell to a closed bar

   A long swell from a distant storm arrives overnight. The buoy off the harbour entrance reports wave height and period rising above the pilots’ limits for the bar. The harbour master closes the entrance to small craft and pilots reschedule arrivals until the swell eases.

   Scope the coast

   The scope reads the coast’s ports, navigation and design needs, existing buoys and the warnings that need wave data. Nexus Observatory Inc. returns the buoy plan, mooring designs, data and quality plan and a price per buoy and per year.

7. De la commande à l’exploitation · Relevé

   Survey the seabed

   Crews survey candidate positions for depth, seabed type for the anchor, exposure to the waves of interest, shipping lanes and fishing grounds, and coverage for reports. Mooring designs follow from depth and seabed. Findings shape the kit for each site before anything is built.

8. De la commande à l’exploitation · Autorisations

   Maritime consent and notices

   Buoys are approved by the maritime authority, marked and lit to the rules for their area, and published in notices to mariners. Fishing communities are told of positions. Every approval is kept with the buoy record. No crew goes to site before its approvals are in place.

9. De la commande à l’exploitation · Fabrication

   Build and test on land

   Buoys are assembled with sensors, node, power and terminal, calibrated, enrolled with their identities and run on land for days. Moorings are built to the design for each position and inspected. Nothing ships until the whole kit has passed its tests together.

10. De la commande à l’exploitation · Installation

    Déployer depuis un navire

    Crews deploy each buoy and its mooring from a vessel at the surveyed position, record the anchor position, and watch the first reports arrive before leaving. Every step is photographed. Crews follow the site safety plan throughout the work. The site record is updated before the crew leaves.

11. De la commande à l’exploitation · Mise en service

    Commission against a reference

    Chaque nœud prouve son identité. Waves are compared with a reference buoy or model over the first weeks, wind and temperature with nearby stations, and quality flags are checked. The buoy enters service when checks pass. Acceptance is recorded with the owner before handover.

12. De la commande à l’exploitation · Exploitation

    Report every half hour

    Pilots, harbour masters and forecasters see waves, wind and temperature every half hour. Coastal engineers receive the long record with its flags, and drift alerts send a vessel at once if a mooring fails. Every alert and action is kept on the record.

13. De la commande à l’exploitation · Maintenance

    Swap and refurbish

    Buoys are swapped with refurbished ones on the agreed plan, sensors cleaned of fouling and recalibrated, moorings inspected and replaced, and software updated remotely. Every change is kept with the buoy record. Maintenance history stays with each site for its whole life.

    Quality-controlled waves

    Wave data pass the real-time quality checks for in-situ surface waves, marine observations follow the WMO instrument guide, and sea state and sea surface temperature are reported as essential climate variables. Every report keeps its flags, position and calibration record.

01Le lieu et ses dangers

Où il fonctionne, et ce qui peut mal tourner.

Operating contextWave data are quality-controlled to the real-time manual for in-situ surface waves, marine observations follow the WMO instrument guide, and sea state and sea surface temperature are essential climate variables. Buoys must survive storms, fouling, vandalism and passing ships.

Dangers

• Buoys that break their moorings in storms
• Fouling that degrades sensors
• Collisions with vessels
• Data gaps in the storms that matter most
• Wave data without quality control
