Abstract: Systems and methods are disclosed for deploying one or more anchor piles on the seafloor using submersible line tensioning systems and techniques to achieve tensioning of mooring lines at the seafloor rather than at the conventional vessel deck level. Among other things, the disclosed systems and methods may be advantageously employed for tensioning mooring lines for Mobile Offshore Drilling Units (MODUs) when additional mooring legs must be added to the original complement of MODU legs, as well as and for tensioning mooring lines for vessels having turret mooring systems, each of which have limited space for surface tensioning equipment.

Abstract: An outboard motor includes a drive shaft that transmits rotational power from an engine, a shift unit provided in the middle of the drive shaft, and a water pump that feeds a coolant to the engine. The drive shaft has a first input shaft that receives rotational power transmitted from the engine and a second input shaft that receives rotational power transmitted from the first input shaft. The shift unit has an upper gear rotating in synchronization with the first input shaft, an intermediate gear meshing with the upper gear at all times, and an intermediate shaft extending to the rear side from the intermediate gear and rotating in synchronization. The oil pump as an accessory is operated by the rotational power transmitted to the intermediate shaft.

Abstract: A lightweight transport vessel transports compressed natural gas underwater without needing to liquefy the gas for transport.

Abstract: There is provided an electric outboard motor. An upper unit is provided to be rotatable in a horizontal direction about a swivel unit. A lower unit is provided below the upper unit and configured to function as a rudder. The upper unit comprises an electric motor supported by a rear side of the swivel unit via a mount unit. The upper unit or lower unit has a gear deceleration device configured to couple an output shaft of the electric motor and a drive shaft extending in an upward and downward direction to each other. The drive shaft is coupled to the gear deceleration device in front of the output shaft of the electric motor and configured to transmit an output of the electric motor to a propeller provided in the lower unit.

A driveshaft is coupled to a crankshaft of the engine, and extends along a driveshaft axis through the adapter plate neck, bearing(s), and oil sump. A steering actuator is coupled to and rotates the oil sump, and thus the driveshaft housing, around the driveshaft axis with respect to the adapter plate, which varies a direction of the outboard motor's thrust.

Abstract: An inflatable shallow draft fishing boat having a removable, inflatable paddleboard floor that provides stable flotation for at least two standing adults, the boat also including an adjustable, detachable rowing frame. The boat can be maneuvered and propelled by oars, a push pole or a small motor. A detachable rowing frame allows the rower to switch his rowing position from facing the stern (for best speed) or face the bow (for better visibility when searching for fish). The paddleboard floor may be held in place by frictional engagement when the boat and the paddleboard are inflated; alternatively, the paddleboard may be removed and function independently as a stand-up paddleboard that can be used for fishing, swimming, or similar recreational water sports. The transom may be shortened for navigating rocky rivers, and measurement markings may be included on the outer side for measuring fish while the fish remain in the water.
