From Eastern Scheldt to offshore industry
Decompression tables should never be considered as "absolutely irrevocable", but must be reviewed regularly, based on data (feedback) reported. This urged DadCoDat after more than 25 years to produce a revision of these tables in 2015, to allow the diving industry to continue using reliable standard tables according to present days standards.
The NDC (Netherlands Diving Centre) decompression tables nowadays are a well known phenomenon in the Dutch diving industry.
Prof. Dr. W. Sterk

The computer model was originally developed in 1975 by Prof. Dr. W. Sterk and was used extensively during the construction of the Eastern Scheldt Storm Surge Barrier (1977-1986) as well as in offshore diving. Based on reported dive data, the model has been refined and proved to produce reliable tables.
Prof. Dr. W. Sterk and Dr. M.P.C. van der Huls, both experienced diving medical experts, undertook the task to update the tables and recommendations in accordance with present days insights. Safety of the diver has remained the most important consideration for the development of these DCD / revised NDC tables
DMAC35 adviced a new variable for avoiding long term oxygen toxicity instead of UPTD / OTU. They think ESOT to be better, as it also predicts the decrease of toxic effects, particularly POT (Pulmonary Oxygen Toxicity).
DCD is not convinced and has made available an addendum to the tables showing both OTU and ESOT, so future will learn what is best. See page New Developments.
