Abstract: A transfer device is configured for transferring bulk material from a barge floating on a body of water into at least one receiving device. At least one lifting lock is provided by way of which the barge can be raised, while floating, to a tilting height above the surface of the body of water, and at least one tilting device is provided by way of which the barge can be tilted such that the bulk material is poured from the barge into the receiving device.

Abstract: An equipment for unloading a bulk carrier comprises a plurality of structures fastened to a fixed platform, the plurality of structures is fastened to the fixed platform mutually parallel, each structure comprising a mobile element having fastening elements which are associated to a projection of at least a removable hold of a bulk carrier, the mobile element being displaced from a first position (A) to a second position (B) so as to tilt at least a removable hold onto an apron feeder and then to a system of conveyor belts. Also, a bulk carrier comprises at least a removable hold including a compartment for transporting bulk products having a plurality of projections disposed in a longitudinal line and mutually parallel at a first end of the removable hold and an articulation mechanism disposed along a second end of the removable hold parallel to and opposite the first end.

Abstract: A working system includes a floating type floating structure, and a working ship configured to perform at least installation or maintenance of the floating structure. The floating structure has a column section whose peripheral surface is located at a waterline when the floating structure is floating, a ballast section arranged below the column section and a flange section arranged at an intermediate portion of the column section. The working ship has a gripping section capable of engaging with the flange section, and a raising/lowering device configured to raise and lower the floating structure.

Abstract: A floatation collar for a sensor package forming part of a detection array comprises two halves that when joined together act as a protective casing that secures and orients a sensor package in an optimal configuration within a water column. The collar comprises a shell tilled with syntactic foam. The cellar top portion includes a series of projections strategically placed to protecting the sensor package transducers against mechanical damage. The base bottom portion of the collar is conical with an integral thimble to allow the collar to ride down and then emerge under a passing trawl net or other fishing lines or cables by presenting a smooth aspect and a secure means of tethering said unit to a bottom anchor.

Abstract: The present invention relates to a barge with an open top container for receiving a cargo mounted on the deck characterized in that the container is pivotally mounted on the deck such that cargo (e.g. marine sand) can be discharged from the barge by tilting of the container about the pivotal axis. The barge is particularly useful for use in land reclamation projects and the invention further relates to a method of reclaiming land utilizing such barges.

Abstract: The present invention relates to a capsule sized to contain a weapon for launching and to withstand depth pressures. A telescoping nose section of the capsule, normally unextended around the weapon, extends at launch along a longitudinal axis of the capsule to provide the buoyancy used to lift the capsule out of a stored state and to ascent the capsule towards the surface. Once the surface is reached, a nose cone of the capsule is jettisoned to allow the weapon to exit the capsule.

Abstract: A system for processing sold municipal waste and nonhazardous commercial waste comprises a multi-level floating marine vessel tied up alongside a dock. The vessel has a processing deck for processing incoming solid waste materials into multiple lines of material-specific recycling bins arranged symmetrically with respect to the midships region of the vessel. The vessel has forward and aft overhangs on the processing deck level big enough to drop load non-recyclable waste at the end of each said line into refuse barges moored directly below said overhangs. The vessel preferably has a tipping deck located above and approximately coextensive with said processing deck on the vessel with at least one opening accessible to trucks from the dock for loading solid waste onto the vessel. A bailing and storage deck located below the processing deck on the vessel has an opening accessible to trucks from the dock for unloading recyclables.

Abstract: A method for the forming and the deposition in a selected place of a bulk consisting substantially of loose or lightly cohesive material, such as sand or other ground material, for example for use as the core or base of a dam, quay, a bank reinforcement, a jetty or a breakwater, for filing holes or trenches in the bed of a waterway, or for the packaging and storage of contaminated material. The invention has for its purpose to carry out a method of the type in such manner that it can be performed very inexpensively and quickly, while nonetheless ensuring an excellent durability of the formed bulk, both in the short and the long term.

Abstract: A method and apparatus for transporting a marine superstructure on a vessel floating in a body of water to a working site, placing the semi submersible part of the apparatus into a body of water, lowering the semi submersible into a stable position, moving the marine superstructure from the vessel and onto the semi submersible, elevating the semi submersible with the marine superstructure over the marine structure, lowering the semi submersible vessel and marine superstructure, causing the marine superstructure to rest on the marine structure, pulling the semi submersible away from the marine structure and marine superstructure and placing the semi submersible back onto the vessel. To remove the marine superstructure from the marine structure and place the marine superstructure onto the vessel the same method is used in reverse.

Abstract: A variable capacity floating articulated barge assembly including two barges which are pivotally connected at their mating ends. An elongated structure to be launched is jacked to initiate it sliding along skidways on each barge toward one end region where a pivotal support member finally supports this structure prior to it being launched from this barge assembly. During launching the barges and the support member of this assembly pivot with respect to each other depending upon the degree and location of the load.

Abstract: A system for maritime transportation and distribution of bulk raw materials includes a series of containers, a carrier vessel, a container unloading dock for unloading material from each container, and a loading dock for loading material into each container, each container having openings in the stern and bow walls for loading and unloading materials, provided with watertight covers and/or valves, and having no hatches on deck so that the containers can be stacked one on the other, the vessel having a hold provided with a port for the flotation loading and unloading of the containers into and out of the hold, the hold comprising retention devices to lock each container to the structure of the carrier vessel, in the stowage position the containers being stacked one on the other in a multilayer arrangement, the unloading dock being a sloping bed graving dock which includes a tunnel located underneath the same in communication with the floor of the dock through openings provided with watertight covers, and a con
