side girder manholes

[Hisham]

Is it available to make manholes in side girders for small vessel (40m length) build under BAS rules?
This point is not covered in rules
(for center girder it is not available)

[PNACS]

You can Cut manholes on Side girders. As a practice, ensure that vertical extend hole is less than d/2 (d= depth of girder). Refer following part of ABS Rule for Center Girder. Same guidelines may be applied for Side girders.
