Title: Rolland Bernollin: Innovator in Sealing Technology
Introduction
Rolland Bernollin is a notable inventor based in Grieges, France. He has made significant contributions to the field of sealing technology, particularly for submarine cables. His innovative approach has led to the development of a unique sealing device that addresses the challenges posed by high-pressure environments.
Latest Patents
Bernollin holds a patent for a sealing device of the gland type for a cable. This device facilitates the passage of a submarine cable, transitioning from a high-pressure volume, corresponding to surrounding water, into a low-pressure volume. The design is particularly beneficial for cables subjected to dynamic stresses. The sealing device features a gland box system with at least two individual packing elements, each crafted as an annular body made of elastomer. These elements are compressed axially within the gland box, allowing them to clamp radially inward against the cable jacket and outward against the gland box. Additionally, the device incorporates washers inserted within the gland box between the packing elements. Notably, the packing element closest to the high-pressure volume includes an integral sleeve portion.
