Apparatus is provided for producing measurement data capable of characterising a burial trajectory (2) traced out in a sea-bed soil (3), and additionally to be capable of measuring a soils parameter such as the penetration resistance of the soil (3). In particular the apparatus checks for the anchorability of a particular sea-bed location and also provides a certain indication of the nature of the soil in stratae in the bed at this location. Specifically the apparatus achieves measurements via a point on a burying apparatus (5) as the burying apparatus moves in the trajectory. More especially the apparatus includes means (19, 29) located in a body (12) carried by the burying apparatus to sense the distance along the trajectory (2) separating two spaced points on the trajectory, and from that by additional means sense the position of a point in the soil at a particular instant thereby enabling the path of the trajectory (2) to be plotted. These additional means can comprise for example an inclinometer (28) indicating the angle of the body (12) at a particular instant. The body (12) can further include a penetrometer (17) to measure soil resistance.
Système servant à recueillr des mesures susceptibles de définir une trajectoire enterrée (2) tracée au fond de la mer (3) et, de plus, certains paramètres du sol tels que sa résistance à la pénétration (3). L'appareil peut en particulier vérifier la capacité d'ancrage de certaines zones du fond et fournir certaines indications sur la nature de strates du sol dans cette zone. Le système effectue de manière spécifique des mesures à l'aide d'un point sur un appareil d'enfouissement (5) alors qu'il progresse le long de sa trajectoire et plus spécialement à l'aide de moyens (19, 20) logés dans un corps (12) solidaire de l'appareil d'enfouissement pour évaluer la distance séparant deux points de la trajectoire (2) ou de moyens additionnels permettant de déterminer la position d'un point du sol à un instant donné et de tracer la trajectoire (2). Ces moyens additionnels peuvent comprendre un inclinomètre (28) indiquant l'angle du corps (12) à un moment donné et un pénétromètre (17) mesurant la résistance du sol.
