P

pallet

A grouping of materials that are to be delivered to and fitted at a certain stage-of-fit of an assembly. The pallet division within a stage-of-fit can for instance be based on the discipline, or the source workshop. Usually, one pallet is used locally in one and the same zone or block and at one and the same workstation.

pallet list

A pallet list (PL) is a list of material related to a pallet, which is usually associated with one or several work orders. It lists the components, parts and possibly consumables (such as welding rods), tools and equipment required to complete the work order(s).

panel

• In shipbuilding in general a panel is a flat structure consisting of several plates with mostly parallel stiffener, typically in the flat of bottom, flat of side or in big platforms or bulkheads.

• Here, the concept of a panel is more general and a panel may range in size and complexity from a small bracket-like structure or a planar plate to a complete deck. The panel is the central modelling tool when creating the hull structure, especially in the internal structure. Panels may be planar (plane panels) in the internal structure or with arbitrary shape in sculptured surfaces (curved panels).

panel bracket

A bracket designed together with a panel.

panel line

A production line where individual plates and stiffeners are successively welded together to form an assembly unit. A panel line is often highly automated and can produce large assemblies.

part

The model item on the lowest level (a pipe part, profile part).

parts list

In general, parts list refers to a list of items according to some criteria. Parts lists can for example, be created per discipline (hull parts lists, pipe parts lists), related to the stage of a product (design part lists with data extracted from a product model under refinement, production parts lists to be used in a workshop), per station in a workshop (plate cutting parts lists, prefabrication pipe lists), related to drawings (diagram lists, instrument lists), related to raw materials (plate parts nested on a particular plate) and in several other ways. The system has a rich repertoire of tools to create parts lists of different kinds and also to allow parts lists to be edited.

PBS

See product breakdown structure.

penetration

The place where a pipeline, ventilation line or cable penetrates a hull item.

picking list

Generated from the requisition list to collect material from a store.

piece part

The lowest level of the assembly hierarchy created in-house. Usually refers to a steel item. In the Hull split process, piece parts (plate parts and profile parts) are created from the design model. A piece part may be physically different from the corresponding nominal design part, for example, compensated for shrinkage, or with excess added.

pillar

Free profile, normally welded at the ends only and supporting decks and platforms in open areas. Sometimes known as stanchion.

planning unit

The level of WBS that is scheduled in the common project plan and thus sets the timing for material need, design schedule and resource need (work force). A planning unit (PLU) is a group of work, often one stage for a zone or block, which consists of work to be carried out at the same time or to be ready at a certain point in time and which requires a certain minimum number of man-hours, typically 200. Some yards equate planning unit with the work related to a pallet list. (Such yards usually use planning with less than 200 man-hours and use the term work package.)

plate

See plate part.

plate development

The process where a shell plate must be developed, that means, subject to an inverse bending operation, so that the plate part can be cut in a proper shape from a planar plate.

plate part

A piece of plate that finally has to be manufactured and used in for example, a panel.

PLU

See planning unit.

pre-assembling

The practice of building sections, large as well as small, of a ship in areas away from the normal building place or dock and then moving them into the normal building ways.

pre-outfitting

The practice of adding outfitting items, for example, pipes and machinery to hull assemblies in an assembly stage.

process analysis

Includes a WBS with additional information such as Gozonto charts that means, isometric of a panel exploded to show piece parts and their relative location.

product breakdown structure

The structure of a product, broken down into an assembly hierarchy.

product information model

The total collection of data about a particular project (ship), that means, about all the physical parts that constitute the final product and all the different associations between them.

product model

See product information model.

production group

A group of workers or a manufacturing equipment facility

profile

A piece that is used as a stiffener, flange or pillar. Profiles are always used as though they should be manufactured from bar material but they may in the end be fabricated from for example, plates.

profile part

A profile piece that finally has to be manufactured and used as for example, a stiffener.

profile type

Specifies the shape of the profile and the parameters, relevant for control of its size.

project

Usually an entire ship or offshore structure. It can also be a part of a ship, covering only some disciplines. The system further has the possibility to define sub-projects.

property

A data element with a name and a value.

purchasing structure

See major equipment list.
