Title
(EN) OFFSHORE MARINE ANCHOR
(FR) ANCRE MARINE DE TYPE OFF-SHORE
Abstract
(EN) A marine anchor (1, 40, 40A, 40B, 40C) for deep embedment in a seabed soil (2) including a fluke member ( 4, 41) and a shank member (7, 49) and means (12, 62, 62A) for constraining a load application point thereon (13, 15, 63, 63A, 65) to lie in first and second directions from a centroid (9,46) of said fluke member (4, 41) forming, with respect to a fore-and-aft direction (10, 47) of the fluke member (4, 41), an acute forward- opening angle (A) and an acute rearward-opening angle (C) respectively whereby said marine anchor (1, 40, 40A, 40B, 40C) can be pulled rearward to bury deeply in a rearward direction (R) after having been pulled forward to bury deeply in a forward direction (F).
(FR) Cette invention concerne une ancre marine (1, 40, 40A, 40B, 40C) pour un ancrage profond dans un fond marin (2). Ladite ancre comprend un élément formant patte (4, 41) et un élément formant verge (7, 49), ainsi que des moyens (12, 62, 62A) pour contraindre un point d'application de charge (13, 15, 63, 63A, 65) situé sur celle-ci à reposer dans une première et une seconde direction par rapport à un centroïde (9, 46) dudit élément formant patte (4, 41) formant, par rapport à une direction longitudinale (10, 47) de l'élément formant patte (4, 41), un angle aigu ouvert vers l'avant (A) et un angle aigu ouvert vers l'arrière (C) respectivement. Ainsi, ladite ancre marine (1, 40, 40A, 40B, 40C) peut être tirée vers l'arrière afin d'être ensevelie profondément dans un sens arrière (R) après avoir été tirée vers l'avant afin d'être ensevelie profondément dans un sens avant (F).
