The invention relates to a method for managing maintenance for a ship comprising a sealed and thermally insulating tank for transporting liquefied gas. The method comprises the steps consisting in determining 310 a current filling level of the tank, determining 320 a current state of movement of the ship, determining 330 a current sloshing index IBi from the current filling level of the tank and the current state of movement of the ship, taking into account the position and the geometry of the tank, integrating 340 the determined current sloshing index IBi into a wear index IUi that takes into account a history of the sloshing indices. The wear index is then compared to a threshold in order to indicate if the tank needs to be inspected, depending on the result of the comparison.

The men's eight according to the invention has an elongated hull that ends in a pointed bow and a pointed stern. Given a total weight of 938 kg, the waterline is 17,211 mm±5%, preferably ±3% and most preferably ±2%. Given division into 15 segments of equal length and in the case of a total weight of 938 kg, particular values are also presented in table form for the respective cross-sectional area below the waterline WL, the respective circumference below the waterline WL, the respective width at the waterline WL, and the respective width ratio based on the middle segment 7, each having a tolerance of ±5%, preferably ±3% and most preferably ±2%. The women's eight according to the invention is designed with similar lines for a total weight of 858 kg.

A sleeved pole-like cleaning device having a pole-like member with a head portion defining a working surface and a removably couplable sleeve with a distal end, a proximal end, a first layer being of a substantially deformably-resilient and polymer-based material, and a second layer coupled to the first layer. The removably couplable sleeve has a first position along a slideable path while the removably couplable sleeve is encapsulating the pole-like member with the distal end of the removably couplable sleeve not substantially adjacent to the head portion of the pole-like member and a second position along the slideable path while the removably couplable sleeve is encapsulating the pole-like member with the distal end of the removably couplable sleeve substantially adjacent to the head portion.

A ship breaking down arrangement (1) comprising,—two waterborne platforms (10, 20) having at least one removing means (60) for removing dismantled parts and/or fluids from a ship (40) which shall be broken;—a midsection (30) placed between and connected to said platforms lifting means provided on the platforms for lifting and lowering the ship between said platforms; and—at least one transporting means (90) for receiving and transporting said dismantled parts and/or fluids to a receiving location, wherein breaking down is performed while the ship is still located at sea. The application also relates to a method for breaking down ships.

A catamaran lifting apparatus is disclosed for lifting objects in a marine environment. The apparatus includes first and second vessels that are spaced apart during use. A first frame spans between the vessels. A second frame spans between the vessels. The frames are spaced apart and connected to the vessels in a configuration that spaces the vessels apart. The first frame connects to the first vessel with a universal joint and to the second vessel with a hinged connection. The second frame connects to the second vessel with a universal joint and to the first vessel with a hinged or pinned connection. Each of the frames provides a space under the frame and in between the barges that enables a package to be lifted and/or a marine vessel to be positioned in between the barges and under the frames. In this fashion, an object that has been salvaged from the seabed can be placed upon the marine vessel that is positioned in between the barges and under the frames.

External External loading test apparatus comprising: a structure with at least three pillars supporting a platform, the platform being configured to receive a podded electric propulsion motor in a hanging position while allowing operation of said pod, at least a test subsystem, for applying a force on the pod to simulate full scale external loading.

A minimally invasive method for attaching to a surface is provided. The method utilizes an attachment apparatus for non-penetrating mechanical attachment of components to a target surface. The apparatus includes a cartridge assembly and mounting assembly. Actuation of the cartridge assembly causes first and second exothermic reactants located between outer casing and the inner casing to come into contact and cause an exothermic reaction. This reaction liquefies a bonding material between the cartridge assembly and mounting assembly, allowing it to flow around the mounting assembly and onto a target surface creating a seal. Vacuum pressure will bind the mounting assembly to a target surface.

A watercraft with improved safety and stability is provided. The watercraft includes a shell defining a plurality of raceways for receiving water during certain maneuvers of the watercraft, thereby excerpting force upon the watercraft in a first direction. The shell is configured so as to prevent or otherwise inhibit the water from excerpting an opposed second force upon the watercraft. An intermediate panel of the shell provides increased flexibility, thereby serving as a shock absorber for the watercraft.

The present invention relates to a vessel data integration system and a vessel comprising same. Accordingly, the present invention preferably comprises: a first vessel data conversion device for converting first vessel data which have a non-standard format and are received from first equipment; a second vessel data conversion device for converting second vessel data which have a standard format and are received from second equipment; a data processing device for classifying, by type, the integrated vessel data received from the vessel data conversion device; a complex event processing (CEP) device for filtering out integrated vessel data, which needs to be transmitted in real-time; and a real-time data transmission device for transmitting in real-time the integrated vessel data.
