    摘要: A remotely operated submersible vehicle for preparing a trench in a subsea bottom is disclosed. The vehicle comprises a frame, hoisting and control cables for suspending the vehicle from a surface vessel, thrusters for manoeuvring the vehicle, and an elongated mechanical excavating tool extending across the width of the trench and connected to conveying means for carrying excavated seabed material to a position outside the trench. The excavating tool comprises an elongated support member that extends across the width of the trench and is provided with a number of cutter devices that are actively driven in a rotation direction around an axis extending substantially perpendicular to the longitudinal direction of the support member in the direction of the trench. A method of preparing a trench using the vehicle is also described.

    摘要: A multi-stage seafloor mining system that has at least concentration stage, a reclamation stage, and a haulage stage. The system includes a concentrating system (50) that processes seafloor materials, a reclaimer machine (300) that collects the processed seafloor materials, and a mechanical haulage system (40) that receives the processed seafloor materials collected by the reclaimer machine (300) and conveys discrete parcels of the processed seafloor materials to a surface vessel (100).

    摘要: This invention relates to dredgers for removing sand, silt and like material from the river or sea bed and has application, for example to clearing wrecks, and providing trenches in which, for example, pipelines may be laid. There is described a dredging apparatus comprising a body (11) mounting first thrust means (24, 74, 75) to direct, in use, a wash of water downwards towards an area of seabed or the like characterised in that the dredging apparatus includes further thrust means (44, 55, 58, 59, 77, 78) to maintain the body of the apparatus above the seabed and to propel the body through the water.

    摘要: Une moissonneuse par aspiration de plantes et d'animaux aquatiques comprend une pompe centrifuge à débit variable capable de traiter des solides montée sur un vaisseau (1) et connectée à un ajutage manoeuvrable (14). L'utilisateur peut commander la position de l'ajutage (14) et le degré d'aspiration appliqué par la pompe afin de récolter de manière sélective des couches d'algues ou d'herbes, etc. sur le lit d'un corps d'eau. Un système de positionnement ou de manoeuvre d'un vaisseau (1) dans des eaux peu profondes comprend des roues à pointes (46) entraînées par des moteurs indépendants (40) à l'extrémité de bras ajustables (41). Les pointes pénètrent dans le lit du corps d'eau afin de positionner et de faire avancer le vaisseau en perturbant au minimum l'environnement.
