Today we deployed the P-Cable system again above the mud volcano. Actually we\u2019ve just finished to deploy it few minutes ago and during the operation I was responsible of the winch! That was an interested experience (really cool in fact) but you have to pay attention to the instructions that you\u2019re given and you have to be aware and careful of the people that are on the desk that they remain safe.<\/p>\n

Do you remember what is the winch and what is it useful for? If not, don\u2019t worry here are some explanations.<\/p>\n

The winch is located and fixed on the back deck where all the operations occurred (picture 2). On it, a cable is wended. This cable is really important since it is where all the 15 streamers will be connected. My job was thus to unwend the cable to let Christian and Wu-Cheng attach the steamers to it, one by one (pictures 3 and 4), and the TORI guys the buoys first near the steamers but also in between (in orange on pictures 5, 6 and 7). At the end, when the cable is completly unwended and the streamers at sea we attached another cable to it which is connected to the second paravane. The P-Cable system is completely deployed then only remains the airgun source.<\/p>\n

Aujourd’hui, nous avons d\u00e9ploy\u00e9 de nouveau le dispositif “P-Cable” au-dessus du volcan de boue. Pour \u00eatre plus pr\u00e9cis, nous venons de terminer \u00e0 l’instant le d\u00e9ploiement et durant l’op\u00e9ration, j’\u00e9tais en charge du treuil ! C’\u00e9tait une exp\u00e9rience tr\u00e8s int\u00e9ressante (vraiment cool en fait !) qui demande cependant de l’attention afin de suivre correctement les instructions et surveiller que les personnes aidant \u00e0 d\u00e9ployer le dispositif soient en s\u00e9curit\u00e9.<\/em><\/p>\n

Vous souvenez-vous \u00e0 quoi ressemble le treuil et \u00e0 quoi sert-il ? Si non, ne vous inqui\u00e9tez-pas, voici quelques explications…<\/em><\/p>\n

Le treuil est localis\u00e9 et fix\u00e9 sur le pont arri\u00e8re o\u00f9 se d\u00e9roulent toutes les op\u00e9rations (2\u00e8me photo). Sur celui-ci se trouve enroul\u00e9 un c\u00e2ble de tr\u00e8s grande importance puisque c’est sur celui-ci que seront connect\u00e9es les 15 fl\u00fbtes sismiques. Mon travail aujourd’hui consistait \u00e0 d\u00e9rouler le c\u00e2ble \u00e0 l’aide du treuil afin de permettre \u00e0 Christian et \u00e0 Wu-Cheng d’y attacher les fl\u00fbtes, une par une (3\u00e8me et 4\u00e8me photo) et aux techniciens de l’institut TORI d’y attacher les flotteurs (bou\u00e9es). Ces derniers sont attach\u00e9s au niveau du raccordement c\u00e2ble\/fl\u00fbte mais \u00e9galement situ\u00e9s (par endroit) entre les fl\u00fbtes (cf. flotteurs oranges sur les photos 5, 6 et 7). A la fin, lorsque le c\u00e2ble est compl\u00e8tement d\u00e9roul\u00e9 et que les fl\u00fbtes sismiques sont \u00e0 l’eau, nous relions le c\u00e2ble \u00e0 un autre c\u00e2ble connect\u00e9 au second paravent. A la fin de l’op\u00e9ration, le dispositif P-Cable est compl\u00e8tement d\u00e9ploy\u00e9; ne reste plus que la source d’air comprim\u00e9.<\/em><\/p>\n
