Details

It has been brought to the attention of the MCA that refurbished Hammar H20 hydrostatic release units (HRUs) have been placed on board ships for use with liferafts.

Such HRUs should not be refurbished and are not guaranteed to work in an emergency which could result in a serious risk to safety. If such a unit is discovered on board it should be withdrawn from service immediately.

This bulletin details the characteristics of genuine Hammar H20 HRUs. This information should be used by all ships to ensure that only genuine units are fitted.
