A decking system, decking components and an installed deck for use on a support structure. The decking system comprises hollow profile planking units having anchor flanges on opposite edges that cooperate with an anchor structure to form a deck or platform. The flanges and the anchor units are shaped and configured to closely interact and form an installed platform structure. The planks comprise an extruded thermoplastic wood fiber composite having an internal structure sufficient to withstand installation, engineering forces placed on the installed platform, weathering and use. The anchor structures have a shape that conforms to the anchor flanges on the decking profiles to hold the deck in place.

A system for use in petroleum production at sea includes a guide frame for one or more riser pipes, on a semisubmersible production vessel. One or more main buoyancy member are arranged separately on at least one riser to carry the main part of the riser's weight. Each riser separately carries a Christmas tree on its top, near a main deck of the vessel. The guide frame comprises vertical main elements extending vertically downwards from the deck, through the splash zone and through the upper, more wave- and current-influenced zone of the sea. The guide frame also includes horizontal guide plates comprising vertically open cells formed of a horizontally arranged framework of beams. Lateral stabilization devices guide the risers' and the main buoyancy members' vertical movement relative to the vessel and restrict horizontal movement of the risers with respect to the guide frame. The guide plates are arranged in at least two levels on the guide frame. A lower guide plate is arranged at the lower ends of the vertical main elements', and a guide plate is arranged just below or near the splash zone. At least one main buoyancy member is held on the riser in level with, and guided by, lateral stabilization devices arranged in one or more guide plates below the upper, more wave- and current-influenced zone near the sea surface. The risers are without buoyancy elements through the splash zone, and thus are less exposed to the water forces in the upper zone of the sea.

The present invention relates to a netpen for breeding, storage, or transport of fish in the sea, in particular completely or in part in open sea regions outside the skerries, wherein the netpen may be lowered in the sea to a desired depth when needed, wherein the netpen may be elevated to a half or approximately half submerged state for various work operations, such as maintenance and inspection of the netpen or harvesting, and wherein netpen has a substantially spherical geometry. The invention is characterized in that the netpen consists of a framework of stays (1, 2, 3, 4) mainly comprising polyethylene or polyethylene-like materials, such as PolyEthylene Low Density (PELD) or PolyEthylene High Density (PEHD), preferably PEHD, a horizontal through center pole (5) also serving as a buoyancy adjusting element for elevation and lowering of the netpen, a horseshoe-shaped working platform (6) having an integrated dock (7) for working vessels, the entire working platform including dock being liftable and lowerable through buoyancy adjustment by means of a designated element (13), and the working deck being mounted on an extended axle (15) on the center pole in such a manner that the netpen may be rotated inside said working deck. On said axle, through lines (8), there are also attached buoys (10) that gives the netpen sufficient reserve buoyancy in normal position as well as weighting organs (9) that, when the netpen is to be stabilized fully submerged at a desired depth, is landed on the sea floor; alternatively, the netpen is stabilized at the desired depth due to the reserve buoyancy in the floatation unit (30) and the floatation element (23), as shown in FIG. 30. Life-supporting functions, such as fodder, energy, and air, are being supplied to the netpen through a lifeline from a nearby floatation unit (30), preferably a platform being an integrated part of the anchoring for the netpen.

A storage array in an automated storage and retrieval system includes storage spaces arrayed on racks along picking aisles, multiple level decks, where at least one deck communicates with each aisle, where the decks and aisles are configured to define a rolling surface for an autonomous transport vehicle at each level of the decks, racks along at least one aisle at each level are at multiple rack levels that are accessed from a respective rolling surface that is common to the multiple rack levels, and a vertical pitch between rack levels varies for a portion of a respective aisle, the vertical pitch between at least two rack levels of the portion of the respective aisle is related to another vertical pitch between at least two other rack levels of another aisle portion of the respective aisle so the vehicle effects multiple picks in ordered sequence in a common aisle pass.

Methods for processing overhead imagery of a vessel include the step of determining an initial classification and classification probability based on the vessel length and length-to-width ratio. Next, mutually exclusive deck features can be extracted from the image. For several embodiments, the extracted deck features that can be spherical tanks, hatches and containers that are stored on deck. The initial classification probability is then weighted using the results of the deck feature extraction step to yield a posterior classification probability for the ship image. If the posterior classification probability is above a predetermined value, the image is assigned a posterior classification. If the posterior probability is below the predetermined value, the vessel image is classified as unknown, and the gross tonnage of the vessel is calculated using the length and width of the vessel.
