プラントに配置される設備とは、LNGプラントを例に説明すると、液化処理の対象である原料ガス中に含まれる酸性ガス(H2S、CO2、有機硫黄等)を除去する酸性ガス除去設備、除去された酸性ガスから単体硫黄を回収する硫黄回収設備、原料ガス中に含まれる水分を除去する水分除去設備、原料ガスの冷却や液化に用いられる冷媒(混合冷媒、プロパン冷媒等)の圧縮設備等が含まれる。ここで、プラントの設備とは、そのプラントの目的に応じて敷設された装置群や機器群のことをいう。
図1は、配管ルーティングシステム1の全体の構成を示す図である。図1に示すように、配管ルーティングシステム1は、複数の端末装置(図1では、端末装置10A及び端末装置10Bを示している。以下、総称して「端末装置10」という)と、サーバ20とを含む。端末装置10とサーバ20とは、ネットワーク80を介して相互に通信可能に接続されている。ネットワーク80は、有線または無線ネットワークにより構成される。
入力装置13は、ユーザからの入力操作を受け付けるための入力装置(例えば、キーボードや、タッチパネル、タッチパッド、マウス等のポインティングデバイス等)である。
メモリ15は、プログラム、及び、プログラム等で処理されるデータ等を一時的に記憶するためのものであり、例えばDRAM(Dynamic Random Access Memory)等の揮発性のメモリである。

プロセッサ29は、プログラムに記述された命令セットを実行するためのハードウェアであり、演算装置、レジスタ、周辺回路などにより構成される。
図2は、配管ルーティングシステム1を構成する端末装置10の機能的な構成を示すブロック図である。図2に示すように、端末装置10は、複数のアンテナ(アンテナ111、アンテナ112)と、各アンテナに対応する無線通信部(第1無線通信部121、第2無線通信部122)と、操作受付部130(キーボード131及びディスプレイ132を含む)と、音声処理部140と、マイク141と、スピーカ142と、カメラ150と、記憶部160と、制御部170とを含む。
音声処理部140は、例えば音声処理用のプロセッサによって実現される。マイク141は、音声入力を受け付けて、当該音声入力に対応する音声信号を音声処理部140へ与える。スピーカ142は、音声処理部140から与えられる音声信号を音声に変換して当該音声を端末装置10の外部へ出力する。
図3は、配管ルーティングシステム1を構成するサーバ20の機能的な構成を示す図である。図3に示すように、サーバ20は、通信部201と、記憶部202と、制御部203としての機能を発揮する。
ユーザが端末装置10を使用してプラント設計を行うとき、端末装置10のディスプレイ132には、プラント設計を行う実際の敷地を模した仮想空間が表示される。その後、ユーザは、ディスプレイ132の画面上で所定の操作をすることにより、仮想空間内に配置する各種機器の種類、及び仮想空間内の配置位置を入力し、機器入力受付モジュール2033は、入力された各種機器の種類、及び仮想空間内の配置位置の情報を受け付ける。
ここで、仮想空間内に配置される機器を示すオブジェクトは、配管が接続されるノズルを始点および終点として備えている。オブジェクトは始点及び終点の情報を含んでいる。
例えば、上記の機能の一部またはすべてについて、端末装置10で入力を受け付けて端末装置10内で処理を行い、端末装置10のディスプレイ132に表示させる構成としてもよい。このような構成にするため、ユーザは、端末装置10を介してサーバ20へアクセスし、サーバ20が提供するプログラムを端末装置10へインストールさせ、端末装置10内で処理を行う構成にしてもよい。この場合、サーバ20の機能として、機器入力受付モジュール2033、機器配置モジュール2034、編集入力受付モジュール2035、パラメータ入力受付モジュール2036、編集表示モジュール2037、またはルーティングモジュール2038の一部またはすべてを備えなくてもよい。
図4は、サーバ20が記憶する機器データベース2021を示す図である。

図5に示すように、設計空間データベース2022のレコードのそれぞれは、項目「空間ID」と、項目「ユーザID」と、項目「空間内配管情報」等を含む。
図6に示すように、配管ルーティングシステム1では、ポンプ、コンプレッサー、タワー、ジャンクションボックス等の各種の機器が使用される。これらは、機器の種類時に応じて決められた設置区画に配置される。
プロセスは、原料を分離、精製して製品、副産物、廃棄物として取り出すために原料や生成物を装置から装置へ送る配管、或いは配管系を指す。
ユーティリティは、プラントの機器を運転または維持するために必要な水、空気、蒸気、燃料、窒素などを送る配管、或いは配管系を指す。
また、可燃性流体を扱う機器や配管が設計圧力を超過すると内部流体は安全弁や制御弁から放出され、フレアースタックで燃焼される。フレアーは、これら安全弁や制御弁から放出された可燃性流体送る配管、或いは配管系を指す。
以下、図11から図19を参照しながら、本実施形態における配管ルーティングシステム1による配管ルーティング処理について説明する。
ステップS111において、ラックには長手方向が指定される。長手方向とは上方から見た平面視で、ラックが延びる方向を指す。ラックの長手方向は、ユーザが別途指定してもよいし、ユーザが編集したラックの形状により指定されてもよい。
ステップS121において、サーバ20の機器入力受付モジュール2033は、端末装置10から送信された各種機器の種類、仮想空間内の配置位置の情報、及びユーザ情報を、通信部201を介して受け付ける。
ステップS112の後に、サーバ20は、入力されたラックの種類、大きさ、及び仮想空間上の指定された位置の情報を受けつけ、仮想空間上に該当するラックを配置する(ステップS121)。
サーバ20は、ユーザが指定した機器の種類、配置位置を受け付ける(ステップS122)。
ステップS122において、サーバ20の制御部203は、プラント設計を行う仮想空間に配置する各種機器の種類、及び仮想空間内の配置位置の入力を受け付けるため、仮想空間を表示させる指示を、端末装置10へ通信部201を介して送信する。
メインラックMRは、長手方向がY方向に沿って延びている。
サブラックSRは、長手方向がX方向に沿って延びている。
タワーTは、メインラックの端部に配置されている、タワーTは、円柱状の構造物である(図25参照)。
図23に示すように、メインラックMRおよびサブラックSRそれぞれのレイヤーの高さは、互いに異なっている。メインラックMRの長手方向と、サブラックSRの長手方向は、互いに直交している。
占有率を確認することで、該当する種類の配管が占める割合を確認することができる。
また、この操作画面では、占有率を視覚的に表したバー(符号R3)が表示されている。バーは、占有率が50%である場合には、レイヤーの領域の半分の空間に延びている。バーを確認することで、レイヤー内の空きスペースがどの程度残っているかを、直感的に把握することができる。
ステップS124の後に、サーバ20は、ユーザから入力された配管設計パラメータを受け付ける。具体的には、ユーザから入力された各項目を、設計パラメータDB2024の新たなレコードとして記録する。
図15に示すように、配管ルーティング処理では、まずルーティングモジュール2038が終始点の特定を行う(ステップS1271)。具体的には、ルーティングモジュール2038は、設計パラメータDB2024に入力された配管設計パラメータから、ルーティングする配管の始点と終点の情報を読み取る。ここで、始点と終点の情報には、配管が接続されるノズルの方向に関する情報が含まれていてもよい。
図16に示すように、ラックの要否判断では、ユーザから、ダイレクト接続の指示の有無を確認する(ステップS301)。ダイレクト接続の指示は、配管設計パラメータとして設計パラメータDB2024に記憶されている。
すなわち、ラックを用いて配管のルーティングを行った際に、ラックに搭載される配管の距離が短い場合には、ラックに乗せるとかえって接続構造が複雑になるため、ダイレクトに機器同士を配管で接続したり、配管がラックを横断したりするように機器同士を配管で接続することとなる。
なお、所定の位置関係については、ラックの1ピッチの半分以下であるという基準に限られず、任意に設定することができる。
一方、ルーティングモジュール2038は、機器同士の位置関係が、所定の位置関係を満たさない場合(ステップS305のNo)には、ラックが必要と判断する。
図17に示すように、配管パスの特定では、ルーティングモジュール2038は、プロセス要求の有無の確認を行う。具体的には、ルーティングモジュール2038は、ユーザが入力したプロセス要求が、設計パラメータDB2024に記憶されているかどうかを確認する。
一方、ルーティングモジュール2038は、プロセス要求がないことを確認した場合(ステップS302のNo)には、ルーティングモジュール2038は、ステップS125において暫定的に設定された配管パスを、正規の配管パスとして採用する(ステップS404)。
一方、ルーティングモジュール2038は、機器がストラクチャに搭載されていない場合(ステップS502のNo)には、機器がタワーであるかどうかを確認する(ステップS504)。ここで、タワー(第4のオブジェクト)とは、例えば蒸留塔のように、高さ方向に沿って立設される円柱状の構造物を指す。
一方、ルーティングモジュール2038は、機器がタワーでない場合(ステップS504のNo)には、ルーティング方法として、機器間ルーティングを採用する(ステップS506)。機器間ルーティングの詳細については後述する。
そして、ルーティングモジュール2038は、機器同士が、ラックをはさむ位置関係ではない場合(ステップS604のNo)には、直接ルーティングを採用する(ステップS605)。直接ルーティングの詳細については後述する。
図20に示すように、ルーティング方法は、機器の属性による区別と、機器とラックとの位置関係による区別に大別される。このうち、機器の属性による区別は、主に配管に機器を接続する際の機器周辺のルーティング方法に関するものである。
そして、ストラクチャ内ルーティングでは、パイピングレイヤーPLに沿って、配管の高さが統一されるようにルーティングが行われる。
この時の端末装置10の操作画面について、図21を用いて説明する。図21は、ルーティング処理を行った際の操作画面の一例を示す図である。
「Gravity Flow」は、始点が終点の高さ以上になっていれば、途中の経路は問わない経路を指す。
「No Pockets」は、始点と終点との間にLow PocketsおよびHigh Pocketsがない経路を指す。Low Pocketsとは、流れ方向に対して、下方向の縦配管の後に、上方向の縦配管があることを指す。High Pocketsとは、流れ方向に対して、上方向の縦配管の後に、下方向の縦配管があることを指す。
「No Liquid Pocket」は、Low Pocketsのない経路、すなわち、液体だまりの無い経路を指す。
「No Vapor Pocket」は、High Pocketsがない経路、すなわち、気体だまりの無い経路を指す。
プロセス要求としては、前述した各条件以外の条件を含んでもよい。
ルーティングモジュール2038は、入力されたプロセス要求により、配管の接続構造を決定する。
これにより、各種機器同士をつなぐ配管のルーティング作業を、ラックの階層ごとに検討することができる。
次に、変形例に係る配管ルーティングについて説明する。この変形例では、予め設定された配管設計パラメータの一部を除外してルーティングを行う処理を説明する。具体的には、制御部203のパラメータ入力受付モジュールは、図11に示すステップS127の前に、ルーティングにおいて無効とする少なくとも1つのパラメータの指定を受け付ける。この際、ユーザは、操作画面から、配管ルーティングを行う上で用いられる各パラメータを無効にするパラメータとして選択する。ここで選択されるパラメータとしては、配管設計パラメータに含まれるパラメータ(例えば、ダイレクト接続の指示、プロセス要求等)、機器の種類(タワー、ストラクチャーの区別)、又はラックを使用するか否かの条件が含まれる。
具体的には、例えば、ダイレクト接続の指示が無効とされている場合には、図16に示すダイレクト接続の指示の確認(ステップS301)において、仮に設計パラメータDB2024にダイレクト接続の指示が記憶されていたとしても、ルーティングモジュール2038はこのパラメータを無視する。すなわちルーティングモジュール2038は、ダイレクト接続の指示は無効としてステップS304の処理を行う。
また、各種のパラメータの一部を無効にして配管のルーティングを行うことで、ユーザがルーティング経路を試行錯誤する場合に、様々なルーティング経路を提案することが可能になり、ユーザの利便性を向上することができる。
また、各処理は、矛盾しない範囲で処理の順番を変更することができる。
