Planners can also load a 40 feet container on top of two units of 20 feet container, this known as a "Russian stowage" or "mixed stowage". [21] Hatch cover clearance – Hatch cover clearance refers to how many "High Cube" (height over 8.6 ft (2.6 m)) containers allowed to load in the hold without preventing the hatch cover from closing correctly.
Each packing problem has a dual covering problem, which asks how many of the same objects are required to completely cover every region of the container, where objects are allowed to overlap. In a bin packing problem, people are given: A container, usually a two- or three-dimensional convex region, possibly of infinite size. Multiple containers ...
Compatibility of container types with ship design, Load and destination locations according to the UN Locode databases and to the Port Call List, Overdimensions, Handling instructions and Loading Remarks (like "away from boiler", "on-deck-only"), Container numbers, False empties, etc. Visualization. Multiple bay views with individual settings
A unit load device (ULD) is a container used to load luggage, freight, and mail on wide-body aircraft and specific narrow-body aircraft. It allows preloading of cargo , provided the containerised load fits in the aircraft, enabling efficient planning of aircraft weight and balance and reduced labour and time in loading aircraft holds compared ...
There are various ways to extend the bin-packing model to more general cost and load functions: Anily, Bramel and Simchi-Levi [48] study a setting where the cost of a bin is a concave function of the number of items in the bin. The objective is to minimize the total cost rather than the number of bins.
The net tonnage calculation is based on a number of factors, one of which is the moulded draft d.The choice of the value to use for d can be complicated. For ships subject to the International Convention on Load Lines, the Summer Load Line draft is used, with the exception of cases where that is a timber load line.
3D printing or additive manufacturing is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
An intermodal container, often called a shipping container, or cargo container, (or simply “container”) is a large metal crate designed and built for intermodal freight transport, meaning these containers can be used across different modes of transport – such as from ships to trains to trucks – without unloading and reloading their ...
