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.

A Method and Apparatus for Wake Enlargement System have been disclosed. By using water pick ups that are mounted on a boat controlled filling of ballast tanks is possible without the use of pumps.

A floating vessel with a buoyant hull for cargo, with a load line presentation device affixed to the buoyant hull without interrupting water flow along the buoyant hull the load line presentation device presenting: a baseline load line indicator plimsoll mark and a plurality of increased capacity load line indicator plimsoll marks, with an increased capacity model in memory connected to a processor in communication with the load line presentation device; the increased capacity model configured for automatically integrating a plurality of variables including: wave size, wave period, wind speed, surface current, vessel length, type of vessel, quantity of disconnected superstructures, quantity of sheer, and bow height and identifying increased capacity load line plimsoll mark for a voyage of the floating vessel, the load line presentation device displays the increased capacity load plimsoll mark improving baseline capacity of the buoyant hull from 1% to 30%.

An advisory system of a vessel that monitors variables of a vessel system inclusive of systems and subsystems that are used to operate the vessel. The advisory system may use machine-learning to learn from an operator (i) whether or not two variables are related to one another, and (ii) likelihood that a variable will reach a threshold, and, optionally, time until reaching the threshold. The system may receive operator feedback (i) to indicate whether the two variables are related to one another, and (ii) whether a behavior of the variable is normal or not normal. Thereafter, if a determination that the same two variables are related to one another and behaving in a similar manner, provide notification to the operator of the behavior. In response to determining that the variable is behaving (e.g., trending) in a similar manner that is not normal, providing a notification to the operator.

A floating VAWT comprising a wind turbine body having a lower body portion and an upper body portion; at least one blade attached to the upper body portion for converting wind energy to rotation of the wind turbine body; and an energy converter attached to the wind turbine body for converting the rotation of the wind turbine body to electrical energy. The energy converter comprises a first energy converter part, and a second energy converter part to be kept relatively stationary in relation to the first energy converter part. The energy converter is attached to the wind turbine body by means of a first releasable mechanical coupling between the first energy converter part and the lower body portion of the wind turbine body, and a second releasable mechanical coupling between the first energy converter part and the upper body portion of the wind turbine body.

An automated plate shaping and verification system allows for the accurate and efficient transformation of a metal plate from a starting shape to a target shape. Using a method for path planning, the system can select heating patterns based on modeling the expected deformation of a particular material type and thickness and identifying candidate heating paths that will sufficiently cause the plate to transform towards the target shape.

Apparatus and methods to couple fuel components to a fuel tank are described. An example method includes coupling a carrier to a guide suspended in a cavity of a fuel tank, where the guide extends in a longitudinal direction between a first end of the guide adjacent a first side wall of the fuel tank and a second end of the guide adjacent a second side wall of the fuel tank opposite the first side wall, and moving the carrier along the guide between the first end of the guide and the second end of the guide.

In an offshore system having a floating vessel, a turret within a hull opening, and a bearing assembly including a support row assembly axially transferring the weight of the turret to the vessel and allowing the vessel to weather vane about the turret, a method and arrangement for in situ remediation of a damaged support row assembly. An outer upper ring is removed from an outer lower ring and a support ring is installed on the outer lower ring. A lower race and support rollers of a remedial support row assembly are installed on the support ring. A reaction ring is positioned above the support ring and connected to an inner ring secured to the turret. The inner ring is axially displaced relative to the outer lower ring and the turret axial loading is transferred to the remedial support row assembly between the support ring and the reaction ring.

A device (100) has surfaces (21, 22, 23, 24) and an anti-biofouling system (10) comprising at least one light source (11, 12) for performing an anti-biofouling action on at least a majority of the surfaces, the at least one light source (11, 12) being adapted to emit rays of anti-biofouling light. The surfaces (21, 22, 23, 24) are configured relative to each other and to the at least one light source (11, 12) such that during operation of the at least one light source, at least a majority of the surfaces (21, 22, 23, 24) is free from shadow with respect to the rays of anti-biofouling light from the at least one light source (11, 12), wherein it may be possible for the rays of anti-biofouling light to reach the surfaces (21, 22, 23, 24) by skimming along the surfaces (21, 22, 23, 24).
