Appendix Table 28 to Subpart G of Part 63 - Deck Seam Length Factors [a] (S[D]) for Internal Floating Roof Tanks

Deck construction	Typical deck seam length factor
Continuous sheet construction^b:
5-feet wide sheets	0.2^c
6-feet wide sheets	0.17
7-feet wide sheets	0.14
Panel construction^d:
5 * 7.5 feet rectangular	0.33
5 * 12 feet rectangular	0.28

^a Deck seam loss applies to bolted decks only. Units for S^D are feet per square feet.

^b S_D = 1/W, where W = sheet width (feet).

^c If no specific information is available, these factors can be assumed to represent the most common bolted decks currently in use.

^d S_D = (L + W)/LW, where W = panel width (feet), and L = panel length (feet).
