Its equipment and such as poor visibility and illumination, confined spaces, systemse ar provided with the right certificates ex works. This sea states, temperature differences, currents, underwater means that a faster deployment of diving systems is possible, noise, decompression sickness and marine life, for example. which therefore reduces costs for customers. Therefore it is governed by an abundance of safety rules and regulations from governmental institutions, business Internationalisation associations and classification societies. Technical and Development in deep and ultra-deep water is booming, operational guidelines are founded on the basis of the most notably in Brazil, West Africa and South East Asia. The approved code of practices as developed for work in the UK decommissioning market is also developing in the north west and Norwegian sector of the North Sea and Atlantic.

IHC Hytech strives to deliver the best value to its customers. It is a partner of choice for innovative, sustainable and integrated hyperbaric systems and diving equipment. IHC Hytech’s solutions are reliable, efficient and flexible to the demands of challenging surface-supplied diving projects. With its extensive knowledge and in-house design capabilities, IHC Hytech ensures compliance with the latest technological developments, strictest safety regulations and most stringent environmental standards. Reliable IHC Hytech excels at managing the complexity inherent within the development of hyperbaric systems and diving equipment. Each project is approached with care, creativity and adaptability, so that customers can depend on delivery within the terms of the agreement.

IHC Hytech is Royal IHC’s in-house specialist in high-quality diving systems and equipment. With a broad customer base that includes various navies, governmental organisations, salvage companies and inshore/offshore diving contractors (both domestic and international), it has extensive experience in designing and manufacturing safe and reliable diving equipment. Royal IHC is also able to integrate diving systems from every reputable supplier. Partnership Specific demands require bespoke designs. IHC Hytech provides cost-effective products, not only when newly acquired, but also throughout their working lives. The IHC Hytech team works closely with the customer and becomes an extension of their organisation, so that both parties can complement each other’s expertise. It can, for example, advise on the design, regulations and structure of the project. This reduces risk and cost to create a smoother process, which leads to better end results.

IHC Hytech silencers provide a significant decrease in noise level, both inside and outside of decompression and hyperbaric chambers. The silencers do not obstruct airflow, they only reduce noise by eliminating turbulence. This is a huge advantage over sintered bronze filters that can corrode, become obstructed, and eventually be blown to pieces by air pressure. Another advantage of IHC Hytech silencers is the possibility to direct airflow for mixing fresh air with the chamber atmosphere sufficiently. The silencers can be used both inside and outside the tank in the exhaust lines, and they are available with a range of connections.
