Definitions
- This invention relates to a seabed gas collection and monitoring device which is operable to monitor the presence of gas in a borehole during drilling downwardly from the seabed .
- Figure 4 is a plan view corresponding to Figure 3;
- Figure 5 is a detail plan view of a further construction of housing:
- Figures 8a and 8b provide a schematic illustration of a preferred development of the device shown in Figures 1 to 4.
- the gas detector device comprises a gas sampling probe 19 (see Figure 3), which is arranged in an outlet pipe 20 of the outlet fitting 18, and which responds to a change in electrical resistance across the probe caused by the presence of gas. in order to detect the presence and the level of gas.
- Sensors 44 and 45 comprise annular arrangements of emitters and receivers, of which each emitter passes any suitable optical signal e.g. an infra red signal through the wall of the clear tube 41 and. when liquid is displaced by a gas bubble to uncover the respective receiver, the receiver can receive this signal and trigger a suitable warning signal, via microprocessor printed circuit board 46 and PSU / data output circuit board 47.
- suitable optical signal e.g. an infra red signal
- the receiver can receive this signal and trigger a suitable warning signal, via microprocessor printed circuit board 46 and PSU / data output circuit board 47.

Abstract
Dispositif (10) collecteur et contrôleur de gaz devant s'utiliser au fond de la mer à proximité de l'entrée d'un trou de forage descendant que l'on perce à partir du fond de la mer à l'aide d'une tige. Le dispositif fonctionne conjointement avec une plaque de base permanente (11) placée sur le fond de la mer, destinée à guider une tige de forage rotative, et dotée de montants de guidage (12) et de câbles de guidage (13) s'étendant de la surface jusqu'auxdits montants de guidage (12) et servant à guider le déplacement du matériel entre une installation de surface telle qu'une plate-forme semisubmersible, et ladite plaque de base (11). Ledit dispositif (10) comporte: un caisson (14) collecteur de gaz ouvert vers le bas et devant se placer au-dessus de l'entrée du sondage pour recueillir les gaz qui pourraient sortir du sondage; un trou (15) ménagé dans le caisson (14) pour permettre à une tige de forage de descendre à travers le caisson; un cadre de montage (16) portant le caisson (14) et pouvant se monter sur les montants de guidage (12) de la plaque de base pour positionner le caisson (14) au-dessus du sondage; un tube de sortie (18) prévu sur le caisson (14) et agencé pour éloigner latéralement du sondage les éventuels gaz recueillis dans le caisson (14); ainsi qu'un dispositif détecteur de gaz (19, 39) télécommandé électriquement et destiné à contrôler la quantité de gaz recueillie par le caisson (14) au cours du forage. Le gaz passe au tube de sortie (18) sans être influencé par la tige de forage tournante.
