Modular anchors

Abstract

A modular anchor comprising: a top cross, wherein the top cross comprises a central tubular pile and one or more arm attachment tubulars and one or more cross arms connected to the one or more arm attachment tubulars and associated methods and systems.

1 . A modular anchor system comprising:
 one or more modular anchors, wherein each of the one or more modular anchors comprise a top cross, wherein the top cross comprises a central tubular pile and one or more arm attachment tubulars and one or more cross arms connected to the one or more arm attachment tubulars, wherein the modular anchor is embedded in a sea floor;   one or more tether lines; and   a piece of subsea equipment, wherein the one or more tether lines are connected to the piece of subsea equipment and the one or more modular anchors.   
     
     
         2 . The modular anchor system of  claim 1 , wherein the one or more arm attachment tubulars comprise four arm attachment tubulars and the one or more cross arms comprise four cross arms. 
     
     
         3 . The modular anchor system of  claim 1 , wherein the central tubular pile comprises a hollow tubular structure. 
     
     
         4 . The modular anchor system of  claim 1 , wherein the one or more arm attachment tubulars each comprise hollow cylinders. 
     
     
         5 . The modular anchor system of  claim 1 , wherein the one or more modular anchors further comprise a central skirt connected to the top cross. 
     
     
         6 . The modular anchor system of  claim 5 , wherein the central skirt comprises a cylinder body and one or more fins. 
     
     
         7 . The modular anchor system of  claim 5 , wherein the central skirt comprises four fins. 
     
     
         8 . The modular anchor system of  claim 5 , wherein the one or more modular anchors further comprise one or more cross arm skirts connected to the one or more cross arms. 
     
     
         9 . The modular anchor system of  claim 1 , wherein the one or more modular anchors further comprise one or more grillage plates connected to the one or more cross arms. 
     
     
         10 . The modular anchor system of  claim 9 , wherein each of the one or more grillage plates comprise grilled steel plates having a trapezoidal shape.
