Tolerance for conductor guide alignment.
The design of anodes is discussed in detail in
Chapter 6
, but, during construc-
tion, the tolerances for the locations of anodes should be less than 300 mm
(12 inches) and less than 10
º
circumferentially of the design position.
Dimensional Control
Quality control (QC) should be within the overall quality plan that was estab-
lished before the start of fabrication. The owner should verify that all persons
and equipment required for QC are available.
Of all the QC areas that require attention, dimensional control is empha-
sized in the code and specifications, especially for offshore structures. How-
ever, it is clear that attention must be paid to the dimensions that have
structural significance, such as the straightness of elements, ovality of tubular
members, eccentricities at node joints, and the like. It is also clear that, on a
