A set of pieces of equipment are schematically shown as a single rectangle 5 in dashed line; the set of pieces of equipment comprises at least one turbomachine or reciprocating machine (e.g. turbine, compressor, pump) and/or at least one combustor and/or at least one motor or engine and/or at least one cooler and/or at least one filter.

(12) Frame 3 comprises a set of vertical beams 4, that may be called columns, a set of horizontal beams 6 belonging to a first floor or first deck, and a set of horizontal beams 7 belonging to a second floor or second deck. Beams 6 are coupled together and to columns 4. Beams 7 are coupled together and to columns 4. Columns 4 are coupled to base deck 2. The frame beams are typically straight, even if curved or angled shapes should not be excluded. The frame beams may be either directly or indirectly connected. The frame beams may be either fixedly or removably connected. Typically, the connection of the frame beams is carried out by welding and/or rivets and/or bolts. Typically, the connection of the frame beams is either direct or through joint pieces.

(13) The base deck may be provided with static supports and/or dynamic (or motion) supports. Base deck 2 is provided with both static supports 8A and 8B and dynamic supports 9. Supports 8A are foundation supports to be used for example at an installation site. Supports 8B are temporary supports to be used for example at a manufacturing plant or on a ship. Supports 9 are trailers to be used for example during motion of the plant module 1 from a manufacturing plant to a ship or from a ship to an installation site.

(14) Referring to FIG. 2, there is base deck 2 of plant module 1 consisting of a grid of beams 21-29, that may be called base beams (according to alternative embodiments the base deck may comprise other components); base deck 2 is designed to be positioned horizontally so the base beams are also horizontal beams. There are for example four peripheral beams 21, 22, 23, 24, one longitudinal internal beam 25 and four transversal internal beams 26, 27, 28, 29. The base beams are typically straight, even if curved or angled shapes should not be excluded. The base beams may be either directly or indirectly connected. The base beams may be either fixedly or removably connected. Typically, the connection of the base beams is carried out by welding and/or rivets and/or bolts. Typically, the connection of the base beams is either direct or through joint pieces. The base beams 21-29 are connected together; in particular, there are four angular joint pieces 10 for connecting the four peripheral beams.

(15) FIG. 3 shows a possible cross-section of peripheral base beam 21; peripheral base beams 22, 23, 24 may have the same cross-section. The other base beams 25, 26, 27, 28, 29 may have for example, the same or a similar cross-section.

(16) FIG. 4 shows a partial lateral view of a first embodiment of peripheral base beam 21 with hexagonal web openings (i.e. openings in the web)so-called castellated-type beam; peripheral base beams 22, 23, 24 may have the same lateral view. One or more of the other base beams 25, 26, 27, 28, 29 may have for example, the same or a similar lateral view.

(17) FIG. 5 shows a partial lateral view of a second embodiment of peripheral base beam 21 with circular web openings (i.e. openings in the web)so-called cellular-type beam; peripheral base beams 22, 23, 24 may have the same lateral view. One or more of the other base beams 25, 26, 27, 28, 29 may have for example, the same or a similar lateral view.

(18) It is to be noted that FIG. 3, FIG. 4 and FIG. 5 may also apply to a frame beam, e.g. any frame beams 4, 6 or 7. Typically, frame beams have a cross-section smaller than base beams.

(19) In general, the plant module (for example 1 in FIG. 1) has a base deck (for example 2 in FIG. 1), a frame (for example 3 in FIG. 1) and a plurality of pieces of equipment (for example 5 in FIG. 1) mounted to the base deck (for example 2 in FIG. 1) and/or the frame (for example 3 in FIG. 1); the base deck (for example 2 in FIG. 1) comprises or consists of a grid of base beams (for example 21-29 in FIG. 2); the frame (for example 3) comprises a plurality of frame beams (for example 4, 6, 7 in FIG. 1); some of or all the base beams (for example 21-29 in FIG. 2) are perforated (i.e. machined to create openings) so that they have a plurality of holes (for example 21-4, 21-5 in FIG. 4 and FIG. 5) for receiving conduits and/or pipes (for example 21-6, 21-7 in FIG. 4 and FIG. 5) and/or trays. The conduits are typically designed to house electric wires and the pipes are typically designed to feed fluids.

(20) In general, the holes in the base beams can take any suitable shape.

(21) In general, the holes in the base beams can take any size suitable for encompassing conduits and/or pipes, and for avoiding cutting, binding, chafing (in general damage) the conduits and/or pipes during assembly and operation of the module.

(22) A tray may be mounted to a hole and serves to support one or more conduits and/or one or more pipes; a tray may be used also for supporting directly one or more cables.

(23) The conduits and pipes may be configured to couple with pieces of equipment internal and/or external to the plant module.

(24) According to some embodiments, all the base beams are perforated, cellular-type or castellated-type, cellular-type (i.e. with rounded shape).

(25) According to some embodiments, the plant module comprises a first plurality of conduits and/or pipes and/or trays. In FIG. 4, for example, there are two pipes 21-6. In FIG. 5, for example, there is one conduit 21-7. In an embodiment, these conduits and/or pipes pass through the holes of the base beams (for example 21-29 in FIG. 2).

(26) According to some embodiments, at least some of the frame beams (for example 4, 6, 7 in FIG. 1) are perforated so that they have a plurality of holes. Some or all of these holes may be useful for lightening the module.

(27) According to some embodiments, the plant module comprises a second plurality of conduits and/or pipes and/or trays. In an embodiment, these conduits and/or pipes pass through the holes of the frame beams (for example 4, 6, 7 in FIG. 1).

(28) The conduits of the first and/or second plurality may house electric wires.

(29) The pipes of the first and/or second plurality may feed fluids.

(30) The trays of the first and/or second plurality may support cables; such supported cables pass through the holes of the base and/or frame beams.

(31) The following may be better understood by considering FIGS. 3, 4 and 5.

(32) At least some of the base beams (for example 21-29 in FIG. 2) and/or frame beams (for example 4, 6, 7 in FIG. 1) may have an H-shaped cross-section; this is shown for example in FIG. 3. The beam 21 has an upper flange 21-1 (that is arranged horizontally), a lower flange 21-2 (that is arranged horizontally), and a connecting web 21-3 (that is arranged vertically).

(33) In an embodiment, an H-shaped cross-section beam is a union of two T-shaped cross-section beams; this is shown for example in FIG. 4 and FIG. 5 through the dashed line in the middle of the web.

(34) More particularly and as shown in the beams shown in FIG. 4 and FIG. 5, the holes of the beams are in the web portions of the beams (so called web-openings).

(35) If the holes in a H beam are in the web and if the H beam is the union of two T beams material and time is saved when manufacturing the finished beam for the plant module.
