I recently spent a few days in my homeland of Northern Ireland and travelled the short two hour trip from England in the large Stena Superfast VII ferry.

Cruiseferry MS Stena Superfast VII of Stena Line.


To pass the time I updated myself with the latest trial work our Primasonics engineers had carried out in the cleaning of dry cargo ship’s holds in Australia. In brief we used a new special acoustic cleaner rig placed within the ship’s hold once the majority of the cement powder had been mechanically removed. The covers were pulled over and the acoustic cleaners sounded. The powerful sonic debonding sound waves caused the cement powder which was clinging to the side walls to debond and fall onto the floor. This exciting new application is a challenging one and we have other important trial work to carry out both overseas and within the UK.

The benefits to the ship owners and crew are enormous in that it would eliminate the need for dangerous and costly manual cleaning of the hold side walls plus a massive saving in dock time and expense. We are keen to work with other bulk tanker owners on further trials and I will keep you updated on progress.

One day Primasonics Macrosonics Acoustic Cleaners will be a permanent feature on the world’s largest dry material bulk tankers – such as the Berge Stahl – one can always dream!
