The subject invention is a design of marine cargo vessel with added mechanical equipment specifically designed to minimize dangerous motions of the vessel induced by high waves while the vessel is being loaded or unloaded from fixed platforms (bottom supported or tension leg) at sea or on inland waters. The vessel uses three means of reduction of such induced motions, which have not before been combined for this purpose. These are a small water plane area multiple hull design, rapid ballasting while loading and unloading, and vertical thrusters.

Multi hull vessel with mechanical systems to facilitate safe transfer of cargo by crane to and from vessel in high waves

An epicyclic gear assembly has a plurality of planetary gear sets secured in a carrier. Each planetary gear set has a planet gear supported by a planet shaft, the planet shaft having its opposite ends supported within the carrier, the planet shaft being capable of defecting along at least a part of its length when the gear assembly is subject to torsional and rotational loads.

Gear assembly with asymmetric flex pin

An epicyclic gear assembly has a central toothed sun gear unit mounted on a carrier plate and plurality of planetary gear sets surrounding the central gear in torque-transmitting relationship. Each of the planetary gear sets has a toothed planet gear supported by a planet shaft, the first end of which is cantilevered from the carrier plate. A second end of the planet shaft supports the planet gear. A double-tapered concave middle portion of the planet shaft allows flexing of the shaft so as to facilitate elastic deflection of the planet shaft while distributing load between the planet gear sets. The outer circumference of the middle portion has a pair of spaced outwardly convex protrusions formed between the first end and the second end.
