Abstract
Description
このような、浮体式海洋石油・ガス生産貯蔵積出設備には、天然ガスなどを圧縮する圧縮機が搭載されている。この圧縮機は、例えば、原油生産過程で石油から分離された随伴ガスを昇圧して、海底パイプラインで陸地へ圧送するなどの目的で使用される。
そこで、本発明は、軽量かつ小型で、波や風による揺れの影響が回転機械に伝わるのを抑制することができる回転機械システムを提供することを課題とする。
上記した以外の課題、構成および効果は、以下の実施形態の説明により明らかにされる。
[実施例1]
<浮体10について>
図2は、本発明の実施例1に係る浮体10を左斜め前方から見た斜視図である。図3は、浮体10を右斜め後方から見た斜視図である。図4は、浮体10をその幅方向に切断した縦断面図である。なお、以下に説明する図1以下の図面においては、X、Y、Z方向を適宜図示している。ここで、X方向は浮体10の水平幅方向、Y方向は浮体10の長手方向(前後方向)、Z方向は浮体10の上下方向である。
以下では、浮体10がFPSOである例について説明する。FPSOは、洋上で原油・ガスを生産し、生産した原油をFPSO自身が備える設備内のタンクにいったん貯蔵して、直接、陸との間を往き来する輸送タンカーへの積み出しを行う設備である。FPSOは、新造の船舶として建造されることもあるが、中古の船舶を改造することで製造されることが多い。
そこで、これらの課題を解決するため、浮体10には、圧縮機103を設けた以下のような構成のベース100を備えた本実施例の回転機械システム1が設置されている。図2、図3の符号111の円内には、浮体10に搭載される回転機械システム1(複数台)を拡大して図示している。
<回転機械40について>
図1は、本発明の実施例1に係る回転機械設置用ベース100をその斜め下方から見た斜視図である。図5は、実施例1に係る回転機械設置用ベース100の上面図、図6は、実施例1に係る回転機械設置用ベース100の下面図である。
すなわち、ベース100は、設置される回転機械40の各機器の配置や重量を考慮した上で、ベース100内の強度部材である桁を適正に配置して桁の量を低減し、製造コストの低減や軽量化や小型化を果たしている。
ベース100の上面部は、防錆処理した鋼板などの板材100iが後述の桁(110~115)に溶接で固定されている。なお、板材100iの桁への固定はボルト、リベットなど溶接以外の方法で固定してもよいが、連続的な固定が可能な点では溶接が望ましい。
被駆動機の増速機102、圧縮機103の重量および回転運動による振動が加わる被駆動機設置領域105の下部には、例えば1個の防振装置109が設置されている。つまり、ベース100は例えば計3個の防振装置107、108、109により支持されている。
ベース100は、ベース100上の各機器を支持するために、複数の桁(110~115)と板100iで構築されている。桁(110~115)は、H形鋼などであり、板は防錆処理を施した鋼板などである。
駆動機設置領域104と被駆動機設置領域105とには、第1桁となる主桁110を備えている。主桁110は、駆動機設置領域104と被駆動機設置領域105とが並ぶ方向(X方向)を長手方向として少なくとも1個設けられ、駆動機となるモータ101ならびに被駆動機となる増速機102および圧縮機103を支持する桁である。本例では、ベース100の両側面部またはその近傍に、ベース100の長手方向に平行にまたは沿って延伸する主桁110、110を一対設置している。
前記の防振装置107、108は、この両側面部の主桁110に取り付けられる。
なお、ベース100の揺れなどを考慮した場合、ベース100および回転機械40などの揺れの慣性力は、ベース100の重力方向(Z軸の下側方向)だけでなく、ベース100の幅方向(ベース100の短手方向、Y軸方向)にも影響するため、ベース100の幅方向の剛性も向上させる必要がある。
桁は、主桁110以外に、駆動機設置領域104と被駆動機設置領域105に、任意の方向に延伸する第2桁(主機第2桁)となる主機補剛桁111、112などを設置する。
例えば、図1に示すように、駆動機設置領域104のモータ101の下方において、モータ101の重量を受ける主機補剛桁111を、ベース100の幅方向(ベース100の短手方向、Y軸方向)に延伸して設けてもよい。
被駆動機設置領域105に、ベース100の幅方向(ベース100の短手方向、Y軸方向)に延伸して設けられる主機補剛桁111aの中央部には、前記の防振装置109が取り付けられる。
駆動機設置領域104と被駆動機設置領域105に必要な剛性は、主桁110がその大部分を担うこととなるため、主機補剛桁111、111a、112は、主桁110より剛性を低くしてもよい。
駆動機、被駆動機以外の図1、図5~図7で不図示の補機131(図2~図4)が設けられる補機設置領域106には、図1、図5、図6に示すように、任意の方向に延伸する第2桁(補機第2桁)となる補機補剛桁113、114、115を設置する。補機補剛桁113、114、115は、補機設置領域106の上の各機器配置、重量を考慮して以下、説明するように、適宜設置する。
そのため、補機設置領域106の両側面部(両側面近傍を含む)に設ける補機補剛桁113は、主桁110のような高剛性の桁は必要無く、その剛性は低くしてもよい。なお、図1、図5、図6では、補機補剛桁113を補機設置領域106の両側面に設けた場合を示している。
すなわち、補機補剛桁113は、補機131の設置面積に応じて、例えば、主桁110の延長上に延伸するように、主桁110と連結して設置してもよい。
その他、補機補剛桁113、114、115は、補機131(図2~図4)の重量、配置に応じて任意の方向に延伸して配置できる。これにより、補機131の重量、配置に応じた適切な桁を補機設置領域106に設けることができる。
補機補剛桁113は、主桁110と連結し、補機設置領域106においてベース100の任意の方向に延伸させてもよい。これにより、補機補剛桁113は主桁110とともに、駆動機設置領域104、被駆動機設置領域105、および補機設置領域106の各荷重を連結して支持することができる。
図7は、本発明の実施例1に係る回転機械設置用ベース100の据え付け例を示す斜視図である。
例えば、ベース100の防振装置107、108、109は、浮体10上の所定の取り付け面31の防振装置設置部121、122、123の位置にそれぞれ設置される。具体的には、防振装置107、108、109をそれぞれ防振装置設置部121、122、123にボルトで締結し、あるいは、溶接により溶着するなどして固定する。
なお、本実施例1の駆動機設置領域104、被駆動機設置領域105、および、補機設置領域106の各領域に設置する桁(110、111、111a、112、113、114、115)は、一般的にH形鋼を用いることができるが、I形鋼やT形鋼などのその他の各種形鋼や、平板を用いてもよい。
また、主桁110、主機補剛桁111、111a、112、および補機補剛桁113、114、115の各剛性は異なってもよい。
しかも、主機補剛桁111、111a、112、および、補機補剛桁113、114、115は、前記のとおり主桁110より剛性の低いため軽量化することができるので、ベース100の軽量化、小型化や、製造コストの低減を図ることができる。これは、FPSOなどに搭載する場合に、ベース100の軽量化、省スペース化が求められるので、好適である。
図8は、本発明の実施例2に係る回転機械設置用ベース200をその斜め下方から見た斜視図である。図9は、実施例2に係る回転機械設置用ベース200の上面図である。
実施例2に係る回転機械設置用ベース200(以下、「ベース200」という)は、駆動機設置領域204と被駆動機設置領域205との間に、ベース中空部217を追加して、ベース中空部217内に補機231を設置する構成としたものである。
実施例2のベース200のうち、既に説明した実施例1の図1、図5~図7に示すベース100と同一の構成、機能を有する部分に関しては、実施例1において100番台の符号を200番台の符号に変えて図示し、詳細な説明を省略する。
このように、補機231の重心位置をベース200内で下げることにより、ベース200に対する補機231のモーメントの腕の長さを縮小させることができる。そのため、補機231からベース200にかかるモーメントが小さくなり、ベース200の変形を抑制することができる。
また、ベース中空部217の剛性が不足する場合は、ベース中空部217を囲む外周部やベース中空部217の底面部に第3桁となる補強桁211k(図8)を追加してもよい。補強桁は、H形鋼、I形やT形などのその他の各種形鋼や、平板を用いてもよい。
なお、ベース中空部217はベース200を、高さ方向(Z軸方向)に貫通するように設けてもよいし、補機231が接続軸201jに干渉しない範囲であれば、ベース200の上の高さ方向の一部まで設けてもよい。
図11は、本発明の実施例3に係る回転機械設置用ベース300の下面図である。
実施例3に係る回転機械設置用ベース300(以下、「ベース300」という)は、実施例1,2のベース100、200がベース幅中心線100c、200cに対称の位置に桁を配置しているのに対して、非対称の位置に桁を配置する構成としたものである。
図11のベース300のうち、既に説明した図1、図5~図7に示すベース100と同一の構成、機能を有する部分に関しては、100番台の符号を300番台に変えて図示し、説明を省略する。
ベース300上に設置している各機器(駆動機、被駆動機、補機)の重心が、ベース幅中心線300cに対して対称位置にあることは少なく、各機器の重量も異なることから、一般的にベース300は、ベース幅中心線300cに対して非対称な負荷を受ける。
また、重心位置306Gに応じて、補機設置領域306では、ベース幅中心線300cの下側の剛性を高くするように補機補剛桁314、315を配置している。つまり、重心位置306Gの重心を支持し、かつ、補機の重量を支持するのに適切な剛性の桁314、315をベース幅中心線300cに非対称な位置に配置する。
図12は、本発明の実施例4に係る例1の回転機械設置用ベース100Aの下面図である。
実施例4に係る例1の回転機械設置用ベース100A(以下、「ベース100A」という)は、主機補剛桁112aを、次のように設置している。すなわち、2本の主機補剛桁112aを、圧縮機103下方の防振装置109の取り付け箇所から主桁110の防振装置107、108に向かって、上面視で斜め方向に互いに幅を広げつつ延伸させている。そして、主機補剛桁112aを、防振装置107および防振装置108の各取り付け箇所に連結している。
ベース100Aのその他の構成は、実施例1の図1、図5~図7に示すベース100と同様な構成であるから、同一の符号を付して示し、詳細な説明は省略する。
実施例4に係る例2の回転機械設置用ベース200A(以下、「ベース200A」という)は、主機補剛桁212aを設置している。すなわち、2本の主機補剛桁212aが、圧縮機203の下方の防振装置209の取り付け箇所から各主桁210の防振装置207、208に向かって、上面視で斜め方向に互いに幅を広げつつ延伸している。そして、機補剛桁212aは、防振装置207および防振装置208の各取り付け箇所に連結している。
ベース200Aのその他の構成は、図8~図10に示す実施例2のベース200と同様な構成であるから、同一の符号を付して示し、詳細な説明は省略する。
実施例4に係る例3の回転機械設置用ベース300A(以下、「ベース300A」という)は、主機補剛桁312aを設置している。すなわち、2本の主機補剛桁312aを、圧縮機303下方の防振装置309の取り付け箇所から各主桁310の防振装置307および防振装置308に向かい、上面視で斜め方向に互いに幅を広げつつ延伸している。そして、主機補剛桁312aは、防振装置307および防振装置308の各取り付け箇所に連結している。
これにより、主機補剛桁312aがベース300Aの3点支持の防振装置307、308、309を結合するように構成されるので、駆動機設置領域304と被駆動機設置領域305とのXY面方向(ベース300A水平面方向)の荷重や、XY面方向での軸周りのねじれに対する剛性がより向上したベース300Aを実現できる。
また、実施例1~4では、それぞれ様々な構成を説明したが、これらの構成を適宜組み合わせて構成してもよい。
以上、本発明の様々な実施例を説明したが、本発明の範囲内で様々な修正と変更が可能である。すなわち、本発明の実施例は、発明の趣旨を変更しない範囲において適宜、任意に変更可能である。
