For the turbine generator T4500, why is an electric-hydraulic start used? Why not use a motor to drive it directly?

I was looking at some information today and saw that the T4500 turbine generator uses hydraulic starting; why is an electro-hydraulic starting system needed? Why not use a motor to drive it directly?

Electro-hydraulic starting was a feature of Solar products in the 1980s; currently, all Solar units use variable-frequency starting. Given the space constraints of the 4500 model, it is not easy to carry out modifications.

From an electrical engineering perspective, motors equipped with hydraulic couplings can reduce the starting current, thereby minimizing the impact on the power grid during startup.
