  We discuss the low energy effective dynamics of gapless excitations of the
mass vortices of systems similar to the Ginzburg-Landau description of
superfluid helium-3 in the bulk B phase. Our approach is to determine the
vortex solution by considering a specific ansatz for the order parameter and
minimizing the free energy. The conditions on the $\beta_i$ coefficients
required for the stability of the various solutions for the order parameter are
calculated. By considering the symmetries that are broken by the vortex
solutions we are able to generate the moduli fields associated with the low
energy excitations of the vortices. Using these fields we determine the
effective free energy describing the dynamics of these excitations.
