A system (102) is configured to monitor energy usage of a surface maritime vessel (100). The system comprises a device (102A) configured to receive characteristic data representing at least one operating characteristic of the vessel, and a device (102A) configured to receive model data representing at least one energy usage model for the vessel. The system further includes a device (102A) configured to process the characteristic data and the model data to generate an output representing a comparison between the characteristic data and the model data.

Freeform, additive manufacturing equipment, processes and products, including residential, commercial and other buildings. A movable extruder places extrudate that solidifies in open space to create scaffolding or skeletons of buildings and other products. Elongated extrudate elements are fused to each other or connected by other means to form a cellular structure. Filler material such as polymeric insulating foam may simultaneously or thereafter be placed within the cellular structure to contribute desired strength, rigidity, insulative, barrier or other properties. Finish materials may also be applied.

Disclosed herein is a marine vessel, which in one example comprises a substantially continuous deck. Also disclosed is an example with a plurality of parallel longitudinally aligned channels extending from the forward deck to the aft deck. The vessel having a vessel cabin resting on and longitudinally movable upon the deck. The vessel cabin in one example having a plurality of rolling wheels attached thereto; wherein the rolling wheels roll upon the deck and allow longitudinal movement of the vessel cabin between the aft region and the forward region. A drive unit (motor) may be provided. The drive unit optionally mounted to the cabin and in one example having a drive wheel mounted to the drive unit and configured to rotate the drive wheel. The drive wheel(s) contacting the deck such that rotation of the drive wheel repositions the cabin between the aft region and the forward region.

This invention relates to a transport system for moving at least one automated maintenance device for large substantially perpendicular surfaces, for example ship hulls, comprising a monorail system which can be laid freely and at least one drive device which can be moved on the monorail system along a movement direction. The at least one drive device has a drive unit with at least one running wheel, and the running wheel can be driven via at least one drive, preferably an electric drive. At least one pressing unit, is provided which is connected to the drive unit). The at least one pressing unit has at least one loading roller which can be pressed onto the monorail system via at least one spring element, and/or a fixing device is arranged on the drive unit, wherein a fixing roller is provided which interacts with the monorail system.

A system for inspecting a tank in a ship, the tank being suitable for containing cargo in bulk. The system has a support member for supporting at least one sensor means for producing sensor data related to the tank. Also, it has at least three suspending means with an elongated flexible member, adapted to connect to the support member, and a winch, with a motor, for winding a length of the elongated flexible member. Moreover, the system has a control unit for controlling the motor of the winches. The suspending means are adapted to suspend the support member in a position inside the tank. The control unit is configured to synchronize the length of the wound elongated flexible member with the position of the support member inside the tank.

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.

In order to provide a rudder blade, which has a low level of weight, is easier and more inexpensive to manufacture, that meets the various strength and stability requirements for various rudder-blade sections, which can be at least partly manufactured in an automated manner and for which the manufacturing of irregular surfaces, in particular, the leading edge, is made easier, a rudder blade is proposed, which has a modular structure, wherein the rudder blade comprises at least two prefabricated rudder-blade segments and is composed of the at least two prefabricated rudder-blade segments.

The present disclosure generally relates to movable offshore platforms for installing wind turbines, and methods of forming the same. The movable offshore platforms are offshore platforms which were previously used in hydrocarbon production, such as jack-up units. The movable offshore platforms may be decommissioned and retrofitted with equipment for installing wind turbines. The movable offshore platforms may be American-made or otherwise Jones Act compliant. Methods of forming the same are also included.

The present invention relates to a method for collecting vessel data using a vessel data model (VDM), a device for collecting vessel data, and a vessel comprising same. Accordingly, it is preferable that the present invention comprises the steps of: acquiring vessel data generated from vessel equipment; and, on the basis of a VDM, converting the vessel data into integrated vessel data having an integrated format, and collecting same, wherein the VDM is generated by combining a vessel model, a system model and a data model, wherein the vessel model is a model defined by hierarchically classifying the vessel equipment, the system model is a model defined by structuring the vessel data, and the data model is a model for defining the attributes and types of the vessel data.
