Liquid drains in core-in-shell heat exchanger

A method of fabricating a core-in-shell heat exchanger disposed on a moving platform, the method comprising:

• arranging one or more cores along an axial length of a shell;
• arranging a plurality of baffles on either side of the one or more cores along the axial length of the shell to prevent sloshing of shell-side fluid;
• and
• disposing a plurality of drains in the shell, at least two of the plurality of drains being horizontally arranged along the axial length on opposite sides of one of the plurality of baffles, the plurality of drains positioned at one or more variable heights, the one or more variable heights including a height above a bottom of the shell and below a top of the shell to maintain a specified fluid level within the shell.

A core-in-shell heat exchanger comprising:

• a shell disposed in an offshore liquefied natural gas processing environment;
• one or more cores arranged along an axial length of the shell;
• a plurality of baffles arranged on either side of the one or more cores along the axial length of the shell to prevent sloshing of shell-side fluid;
• and
• a plurality of drains, at least two of the plurality of drains being horizontally arranged along the axial length of the shell on opposite sides of one of the plurality of baffles, each of the plurality of drains positioned at one or more variable heights, the one or more variable heights including a height above a bottom of the shell and below a top of the shell to maintain a specified fluid level within the shell.
