A clustering method includes the steps of: creating a plant model in which connection relationships between a plurality of devices ( 31 ) forming a processing plant ( 1 ) and pipes ( 4 ) are represented by a graph showing a linking relationship between a node ( 51 ) and an edge ( 52 ); setting, regarding the plant model, a cluster division condition; and performing, by a computer, the cluster division of the plant model by searching for an edge between the clusters in which modularity is further increased while the cluster division condition is satisfied.

A module for plant configuration of the present disclosure includes: a frame; a cable rack extending in a lateral direction and provided on the frame to support a cable extending in the lateral direction; and a workbench that is provided on the frame along an extending direction of the cable rack and along which a worker moves to lay the cable on the cable rack.

Provided are a device design assistance method and device design assistance apparatus. The device design assistance method includes: a model generation step of generating, after receiving device design data including a design shape relating to structural design of a device to be installed in a plant, a three-dimensional model based on the device design data; a first model update step of updating, after receiving device manufacturing data including a change content with respect to the design shape regarding manufacturing of the device, the three-dimensional model based on the device manufacturing data to generate a three-dimensional model; and a second model update step of updating, after receiving device connection data including a change content with respect to the design shape regarding connection to a peripheral device installed around the device in the plant, the three-dimensional model based on the device connection data to generate a three-dimensional model.

A design support apparatus is provided and includes: a storage unit for storing a graph structure data in which a component to be provided in a plant being designed are defined as a node, and a connection relationship between two components is defined as an edge; an acquiring unit for acquiring the graph structure data from the storage unit in response to an acquisition request from a terminal apparatus that performs each of multiple design steps; an output unit for outputting the graph structure data to the terminal apparatus; and an updating unit for updating the graph structure data stored in the storage unit based on output data of a design step performed by the terminal apparatus using the graph structure data. The graph structure data is shared among multiple design steps, and becomes more detailed from an upstream step toward a downstream step of the plant design.

Provided is a method of constructing a foundation for a structural body, the foundation including a footing and a pedestal, the method including: a formwork formation step of forming, from concrete or mortar, a formwork being an integrated formwork for the footing and the pedestal by using a 3D printer, and a supplying step of supplying concrete into the formwork. The formwork has such a shape that a horizontal sectional area decreases from the footing toward the pedestal.

A construction method of a structure provided with a lower structure part entirely arranged below a ground surface and an upper structure part at least a part of which is arranged below the ground surface on the lower structure part, the construction method including a step of constructing the lower structure part below the ground surface, a step of allowing a heavy object to travel on a travel route including a range that affects the lower structure part after the lower structure part is constructed, and a step of constructing the upper structure part on the lower structure part after the heavy object is allowed to travel.

Provided is a technology of preventing an increase in size of a treatment plant, which may be caused when a safety clearance for the prevention of spread of a fire is set, and restraining an increase in designed fire-extinguishing water usage. A treatment plant for handling a flammable liquid includes: an equipment placement region in which a plurality of equipments configured to handle the flammable fluid are placed, the equipment placement region being divided into four or more firewater supply sections. A plurality of fire-extinguishing water supply facilities are provided to the firewater supply sections, respectively, the fire-extinguishing water supply facilities each being capable of, when a fire occurs in the firewater supply sections, simultaneously supplying fire-extinguishing water to a fire-occurrence section and an adjacent section.

Provided is a management apparatus being an apparatus for managing a project through use of work packages being work units, the management apparatus including: a setting unit configured to create a work package in which a work and a product of the work are associated with each other; and a generation unit configured to generate a list of candidate work packages each being a candidate of a predecessor work package of the work package based on a product required for execution of the work of the work package, wherein the setting unit is configured to set a candidate work package selected from the list as the predecessor work package of the work package.

A plant construction method is provided and includes: installing a group of devices ( 2 ) for processing fluid; and forming, by a 3D printer ( 1 ), a framework structure ( 3 ) configured to support a piping ( 5 ), which allows the fluid to be transferred among devices ( 2 ) included in the group of devices ( 2 ), in a region different from an installation region for the group of devices ( 2 ). When the framework structure ( 3 ) is thus formed by the 3D printer ( 1 ), the group of devices ( 2 ) for processing the fluid can be installed without being restricted by the step of forming the framework structure ( 3 ). There is no need to secure a plot for assembly of the framework structure ( 3 ), and hence a construction site can be reduced in size. It is not required for workers to come to the construction site and assemble the framework structure ( 3 ), and hence safety is enhanced.

Provided are a module for separate conveyance, which is inexpensive and can easily be conveyed via any route, a structure for a plant, which uses the modules for separate conveyance, and a method of constructing the structure for a plant. A module for separate conveyance, to be conveyed in a separate manner and stacked at a construction site includes: column portions to be provided upright in a vertical direction; and a horizontal structural portion to be provided in a horizontal direction between the column portions. The horizontal structural portion directly separates tier spaces adjacent to each other in an up-and-down direction when the modules for separate conveyance are stacked.
