You can get close by setting org-calc-default-modes as follows:

(setq org-calc-default-modes '(calc-internal-prec 12
                               calc-float-format (float 8)
                               calc-angle-mode deg
                               calc-prefer-frac nil
                               calc-symbolic-mode nil
                               calc-date-format (YYYY "-" MM "-" DD " " Www (" " hh ":" mm))
                               calc-display-working-message t
                               calc-hms-format "%s@ %02s'"))

This is the default setting except for calc-hms-format. It does not
quite do what you want, but it's close (I expected the %02s to zero-fill
on the left, but apparently it does not for the %s format):

|----------|
| Duration |
|----------|
| 2@ 15    |
| 2@ 30    |
| 2@ 30    |
| 0@ 45    |
|----------|
| 8@  0'   |
