MODULAR FRAME SYSTEM AND METHOD FOR HOLDING SUBSEA EQUIPMENT

摘要

A modular subsea equipment assembly including a modular base frame and a plurality of modular superstructure devices for selective attachment to the modular base frame for supporting various components and for attachment to underwater cables. The modular base frame includes a frame member forming an outer periphery of the base frame, and a plurality of cross bars extending between opposite portions of the frame member in one or more directions, the frame member and cross bars having at least upper surfaces each having a plurality of connection points for attaching selected modular devices of the assembly to the base frame in a plurality of different possible configurations.

1. A modular subsea equipment assembly, comprising:
a modular base frame; a plurality of modular superstructure devices configured for selective attachment to the modular base frame in a plurality of different possible configurations of two or more modular superstructure devices, each modular superstructure device comprising a mounting device for supporting or attachment to a respective component of an underwater system, and a base mount configured for attachment to the upper surface of the base frame; a cover member of trawl-resistant shape having a peripheral rim configured for attachment to the base frame and enclosing the superstructure devices on the base frame; the modular base frame comprising a frame member forming an outer periphery of the base frame, and a plurality of cross bars extending between opposite portions of the frame member in one or more directions, the frame member and cross bars having at least upper surfaces each having a plurality of connection points for attaching selected modular superstructure devices to the base frame in a plurality of different possible configurations, wherein the connection points on the frame member and cross bars together and independently form multiple arrays of connection points of different sizes and with different numbers of connection points; each base mount of the respective modular superstructure devices including an array of connection points configured for alignment with connection points of any selected array on the modular base frame of size matching the array of connection points on the respective base mount; and a plurality of fasteners configured for attachment of respective base mounts of selected superstructure devices to the base frame via aligned connection points of the respective base mount and the selected matching array of connection points on the base frame.
