Hull Technician-HT -- HTs are responsible for maintaining ships' hulls, fittings, piping systems and machinery. They install and maintain shipboard and shore based plumbing and piping systems. They also look after a vessel's safety and survival equipment and perform many tasks related to damage control.

A Hull Tech is not the same as a Damage Controlman (DC). Yes, HT's duties do include damage control, but the prime shipboard responsibilities are handled by DC-men. They are seperate Rates.
