We consider the unit to bee quite tight, with too limited space for the operators to reach individual equipment items and propose the following:

all hand valves and instrumentation should be good accessible by operators
Create a walkway of 1,5 m wide in the center of the the skid and line-up two rows of main equipment items at both sides of the walk way
Create a walkway of min 80 cm at the outside (both on left side and right side)
This will result obviously in a larger skid, but we think it is essential from operational point of view
