Abstract: The present invention relates to a ship for recovering ocean waste. The ship for recovering ocean waste according to the invention has at least one tank (3) that passes through the ship from the prow (6) to the stern (7), the tank (3) being open at its two ends and being equipped with at least one row (10, 20, 30, 40, 50, 60, 70) of collecting devices (8). The ship according to the invention is characterized in that the collecting devices (8) of at least one row are disposed such that they have openings (5) or spaces (5) between one another. This disposition of the collecting devices allows fish to pass easily through the rows of devices, while waste is collected efficiently.

Abstract: The invention relates to a floating and submersible high-sea aquaculture installation. The objective of the present invention is to create a floating and submersible high-sea aquaculture installation that offers better stability, particularly in its submerged or semi-submerged state. According to the invention, this objective is achieved by a floating and submersible high-sea aquaculture installation (1) comprising a structure (2), fish-rearing cages (3) and at least two first adjustable-ballast floats (4) which are located in the bottom third of the structure (2). The installation (1) according to the invention is characterized in that it further comprises at least two second floats (7) which are located in the top third (8) of the structure and which are able to support at most 50% of the weight of the structure.

Abstract: The present invention relates to a ship for recovering ocean waste. The invention aims to provide a means for recovering waste floating in the sea. Said aim is achieved by a ship (1) that recovers ocean waste, comprising at least two lateral hulls (2) which define a basin (3) therebetween. The ship according to the invention is characterised in that the basin (3) is open at the two ends thereof (6, 7) and comprises a plurality of consecutive sections (11, 12, 13) from the bow (6) to the stern (7) of the ship (1), each of which is provided with at least one collection device (21, 22, 23), the collection devices (21, 22, 23) of each section (11, 12, 13) being capable of collecting objects of different sizes, the sections (11, 12, 13) being arranged such that a device capable of collecting smaller objects is arranged behind a device capable of collecting larger objects.

Abstract: The aim of the present invention is to propose an offshore aquaculture installation in a healthy environment for fish, having the smallest possible impact on the environment in terms of pollution, with a combination of technical means ensuring the stability of the structure and the safety of humans, with all the equipment necessary for easy offshore operation. This aim achieved by an offshore aquaculture installation comprising one or a plurality of cages (1) for breeding fish and a floating structure (2) that is ballasted and submersible.

Abstract: A rescue ship for a disabled vessel includes a hull which delimits an elongated dock (12) which is at least 150 m long and preferably at least 250 m long and at least 30 m wide and preferably at least 45 m wide, and including a ballasting device enabling draught modification by at least 15 m and preferably at least 20 m. The hull has two lateral hulls capable of being ballasted (14) and enclosing the dock (12), and the stem has a practically sealed door (18) which can close the rear of the dock (12). The ship further includes maneuvering elements designed to exert a thrust in one direction transverse at least to the longitudinal axis of the ship. The invention is applicable to the rescue of disabled vessels.
