Marine Geotechnical

Dando rotary heads hold a longstanding reputation for being the favoured choice of many of the largest marine geotechnical drilling companies in the world.

The relationship which we have with our clients and our understanding of their needs has allowed our design team to create both models in exact accordance to the industry’s highest expectations. This combined with traditional British ideals of heavy duty, hard-wearing components explains why the MK500 and MK1000 power swivel are preferred by geo-marine companies worldwide.

In addition to this, our experience in manufacturing and the industry means we can quote and supply suitable water swivels, control panels and other equipment which may be needed for our clients’ bespoke rig designs. Dando are also able to recommend specific gear arrangements and associated flow and pressure details to ensure the correct torque and rpm is achieved.
