The first bulk cargo to be shipped from England to America was in July 1620 in a ship called Mayflower – its cargo- men, women and children! There were over 100 people plus 20-30 crew. This ship was considered at that time to be one of the most modern bulk cargo ships to be built and despite some terrible Atlantic storms it survived to land the first settlers on shore after enduring 66 days at sea. One woman, Elizabeth Hopkins gave birth, whilst at sea, to her first son aptly names Oceanus.

They first landed at Cape Cod on November 11, 1620 before sailing up the coast to Plymouth where they started to build their town where a group of Wampanoag People had lived. For a complete story click here.


I began thinking of the Mayflower as 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 cleaning 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 tanker, the Berge Stahl – one can always dream!
