Barkston Plastic Engineers have completed the manufacture of a new, longer lasting cradle which forms part of an ocean bottom system monitoring previously unobtainable seismic movements at depths of up to 6km below sea level.

The problem posed was for Barkston to manufacture an improved cradle which would survive in the hostile sea environment, providing a solution which outperforms the previous steel/metal cradle.  On the deep sea bed, even the highest specification metals, such as stainless steel, soon succumb to the corrosive effects of salt water, effects which are amplified intensely by pressure. The engineering team at Barkston rose to the challenge of manufacturing an improved cradle, and ultimately decided upon the use of polypropylene. The focus of design then shifted to ensuring the structure could be made as rigid as possible.

Sales Director, Ian Deakin said “ The strength of our engineering team lies in their abilities to engineer products that can out-perform alternatives – products which work longer and harder without the need for maintenance/repair and so reducing downtime.  In this case our new cradle will reduce the need for replacement.  These are key ways in which we help our clients add value.”

The new cradles are manufactured from rigid HDPE and have been designed to safely contain sensor equipment glass spheres holding electrical devices.    Ocean bottom systems are crucial in expanding our understanding of coastal and deep-sea seismic processes.
