What are regulations for Bulk carriers regarding loading equipments as per SOLAS?

As per SOLAS Chapter XII, Regulation 11

Bulk carriers of 150 m in length and upwards shall be fitted with a loading instrument capable of providing information on hull girder shear forces and bending moments Bulk carriers of less than 150 m in length constructed on or after 1 July 2006 shall be fitted with a loading instrument capable of providing information on the ship’s stability in the intact condition .


A loading instrument is an instrument which is either analog or digital and by means of which it can be easily and quickly ascertained that, at specified read-out points, the still water bending moments, shear forces, in any load or ballast condition, do not exceed the specified permissible values.

The loading instrument may also be used to perform stability checks if it incorporates stability software. If stability software is installed on board vessels contracted on or after 1 July 2005, it should cover all stability requirements applicable to the vessel and is to be approved by classification  society.
