Niveau 2 tables

  1. 1. Cours N2 – tables 1 Cours N2 : Tables • Sommaire – Justification – Présentation des tables – Plongée simple – Procédures anormales ou exceptionnelles – Plongées consécutives – Plongées successives
  2. 2. Cours N2 – tables 2 Justification • En tant que plongeur N1 vous avez appris : – Que l’on ne remonte pas plus vite que le guide de palanquée – Que l’on doit parfois faire des « arrêts » (ou paliers) que votre guide de palanquée vous imposait, et on vous a appris l’existence d’une « courbe de sécurité » Nota : à 10 m on peut rester 5h30 !
  3. 3. Cours N2 – tables 3 Justification • Nous avons vu dans le cours sur les ADD que ceux-ci sont dus à la désaturation non contrôlée de l’azote dissous dans le corps pendant la plongée. Votre moniteur gérait ceci (entre autres) !
  4. 4. Cours N2 – tables 4 Justification • En tant que plongeur autonome, vous allez devoir gérer vos paramètres de plongée. Différents moyens existent : – Ordinateurs – Tables • MN90 • Comex • GERS • … Les tables officielles pour les épreuves théoriques des examens sont les tables MN90 Ayez toujours des tables avec vous car un ordinateur peut tomber en panne !! Pourquoi des tables à l’époque des ordinateurs ?
  5. 5. Cours N2 – tables 5 Présentation générale des tables MN90 • Conditions d’utilisations des tables MN90 – Plongée Loisir (conçues pour un effort modéré) – 2 plongées par 24 heures – Vitesse de remontée 15 à 17 m/mn – Entre paliers et entre le dernier palier et la surface : 30 secondes – Plongée à l’air – Plongée au niveau de la mer • Contenu – Les tables proprement dites – Les tableaux 1 à 4
  6. 6. Cours N2 – tables 6 Structure des tables MN90 • Tables de plongées à l’air – On entre avec les Paramètres de plongée • Profondeur + Durée – On en déduit • Paliers (colonnes 3m, 6m, 9m, 12m et 15m) ->durée • Durée Totale (de) Remontée : DTR • GPS Profondeur Durée DTR GPSPalier 9h40 10h26 6m 3m 1’ 4’ 50m
  7. 7. Cours N2 – tables 7 Structure des tables MN90 • Les paramètres de plongée Pas d’interpolation : prendre durée et profondeurs immédiatement supérieures La profondeur : la profondeur maximale atteinte lors de la plongée P La durée : Temps mesuré entre le moment ou l'on s'immerge et celui ou l'on décide de remonter à la vitesse préconisée Durée Pourquoi ?
  8. 8. Cours N2 – tables 8 Exemple • Les paramètres de plongée Palier DTR GPS Profondeur : 20 m Durée : 35 min Profondeur : 35 m Durée : 18 min Palier DTR GPS Profondeur : 36 m Durée : 18 min Palier DTR GPS
  9. 9. Cours N2 – tables 9 Plongée simple • Définition –Une plongée simple est une première plongée ne succédant à aucune plongée dans un intervalle de 12 heures • Exemple Pierre et marie s’immerge à 10h 20 pour une plongée de 40 minutes à 20 mètres Palier DTR Heure de sortie GPS (faire le graphique)
  10. 10. Cours N2 – tables 10 Plongée simple Remontée lente : une remontée à une vitesse < 15m/min est considérée comme lente. la durée de la remontée est incluse dans la durée de la plongée 10h 10h 20 : remontée le long tu tombant 10h 30 : demi tour en longeant le tombant 10h 48 Durée de la plongée = Attention la DTR des tables est alors fausse -> tableau IV 23m 8m 15 m
  11. 11. Cours N2 – tables 11 Plongée simple Exercice Reprenez l’exemple précédent : profil de la plongée, paliers, heure de sortie et GPS ?
  12. 12. Cours N2 – tables 12 Procédures exceptionnelles ou anormales • Interruption ou non exécution de palier On doit avoir rejoint le palier interrompu en 3 minutes (depuis l’interruption de palier) et le recommencer en totalité, puis exécuter normalement les autres paliers prévus Palier de 4 min. Interrompu au bout de 2 min 3 minutes maxi Palier de 4 min. repris en totalité On reprend la procédure initiale 10h 20 m 50 ‘
  13. 13. Cours N2 – tables 13 Procédures exceptionnelles ou anormales Exercice • Martine et pierre, niveau 2, s’immergent à 10h40 et plongent à 23 m. à 11h15, ils décident de remonter. Au bout de 3 minutes de paliers, ils font surface car effrayés par un énorme barracuda : CAT ?, heure de sortie, GPS
  14. 14. Cours N2 – tables 14 Procédures exceptionnelles ou anormales • Remontée rapide On doit se ré immerger en moins de 3 minutes Pour : -exécuter un palier de 5 minutes à mi profondeur, -rejoindre la surface en prenant comme durée de la plongée le temps depuis l’immersion initiale jusqu’a la fin du palier de 5 minutes -effectuer au moins un palier de 2 minutes à 3m > 17m/min 3 minutes maxi Au minimum un palier de 2 minutes à 3mètres un palier de 5 minutes P ½ P
  15. 15. Cours N2 – tables 15 Procédures exceptionnelles ou anormales Exercice • Martine et pierre, niveau 2, s’immergent à 10h40 et plongent à 22 m. à 11h10, pierre fait surface, stab gonflée. Conduite à tenir, heure de sortie, GPS
  16. 16. Cours N2 – tables 16 Plongées consécutives • Définition • Protocole Une plongée est dite « consécutive » si l’intervalle de surface est de moins de 15 minutes On considère alors qu’il s’agit d’une seule et même plongée : Profondeur : la profondeur max des 2 plongées Durée : la durée cumulée des 2 plongées
  17. 17. Cours N2 – tables 17 Plongées consécutives • Paramètres de la 2° plongée – P = max(P1,P2) = – D = D1+D2 = < 15 minutes D1 = 30 min D2 = 12 min P2P2 = 15m P1 = 25 m 10h Heure de sortie = GPS =
  18. 18. Cours N2 – tables 18 Plongées consécutives • Exercice • Martine et pierre, niveau 2, s’immergent à 10h et plongent à 22 m. Ils font surface à 10h35. Ils se ré immergent à 10h45 pour une profondeur de 14m et 12 minutes. Graphiques, heure de sortie, paliers, GPS.
  19. 19. Cours N2 – tables 19 Plongées successives • Définition • Protocole Une plongée est dite « successive » si l’intervalle de surface est compris entre 15 minutes et 12 heures Majoration de la durée de la 2° plongée en fonction du GPS de la première plongée de l’intervalle de surface -> Tableaux I et II de la profondeur prévue de la 2° plongée La deuxième plongée se planifie avant !
  20. 20. Cours N2 – tables 20 Plongées successives GPS de la première plongée Intervalle de surface Pas d’interpolation : prendre Intervalle surface immédiatement inférieure Exemple GPS = L , intervalle = 2h55 Pourquoi ?? • Détermination de l’azote résiduel
  21. 21. Cours N2 – tables 21 Plongées successives N2 résiduel issu du tableau I Profondeur de la deuxième plongée Pas d’interpolation : prendre Azote résiduel immédiatement supérieur Profondeur immédiatement supérieure Pourquoi ?? • Détermination de la majoration Exemple Profondeur prévue : 24m
  22. 22. Cours N2 – tables 22 Plongées successives • Exemple • Paramètres de la 2° plongée – P = ? – D = ? Intervalle = 1h 45 D1 = 35 min D2 = 12 min P2 = 21m P1 = 36m 1° plongée : GPS= L 2° plongée Tableau I N2 résiduel = 1,12 ( on prend 1h30 car 1h 45 n’existe pas) Majoration = 40 minutes ( 1,16 et 22 mètres) « Durée » de la 2° plongée = 52 minutes 10h GPS=L Majoration
  23. 23. Cours N2 – tables 23 Plongées successives • Et si la profondeur réelle de la deuxième plongée n’est pas la profondeur planifiée ? Prof réelle < prof planifiée On ne change rien ! Même majo. Prof. planifiée Prof réelle > prof planifiée On conserve la majo. On utilise la prof. réelle
  24. 24. Cours N2 – tables 24 Plongées successives •Exercice • Jean et Hélène effectuent une première plongée à 10h 03 pour une profondeur de 20m et d’ure durée de 35 minutes. •Ils se ré immergent à 14h pour une deuxième plongée à 18m. Ils ne souhaitent pas faire de palier. Durée maximum de la deuxième plongée ?
