(OP)
Is there a simple methodology to increasing the moment capacity of a HP section by adding web stiffener plates? The application is a HP12x53 used as a waler for a braced sheet pile wall. I need to increase the flexural capacity at the strut locations since larger beam sizes are not available.

You state at the strut location, sounds to me like negitive moment. A cover plate would be the best solution because the high moment at the strut locations does not extend far from the support.

When compared to a typical W shape with it's thick flanges and thin web, the HP geometry is "wrong" for use as a beam: the flanges are thin but wide.
As beams, HP may have lower allowable stresses since they tend to be non-compact shapes.

I see, and specifiy, HP sections used as walers for sheet pile shoring all the time. Though they are not designed for this, they generally are the most econmical as pile driving contractors often have stacks of different HP sections sitting in thier yard.

Stitch welding walers to the sheetpiles is usually not possible. Even when driving frames are used, sheet piles do not go in straight. You are likely to have gaps of an inch or more where welds are requied. If the piles are driven wild, chances go from slim to none.
However, walers are generally supported at intervals by I or T stubs welded to the pile. Welding the walers to the stubs can provide adequate bracing.
