This book recalls the development of founding technology developed during the past 15-20 years to produce a Riserless Drilling System. This adaptive and innovative technology is now allowing operators and contractors alike, associated with offshore drilling or mining, to establish objectives hitherto considered not attainable with conventional drilling methods. The culminating summary explores today's activities and offers an insight into future activities and developments in this inhospitable region of our 'inner space'.

The author has spent more than the past 40 years working at the forefront of the offshore energy industry and continues to work on current developments towards successful geophysical surveying in the deepest of the world's oceans.
