About Us

Welcome to CDA(S)

The Commercial Diving Association (Singapore) was formed in 2009 with the full support of the Workplace Safety & Health Council, and was formerly registered in Jan 2010.

The Commercial Diving Association (Singapore) seeks to promote Safety and Professionalism in the Commercial Diving industry in Singapore. We do this through the adoption of industry best practices by all the member companies, and the promotion of these best practices in the industry as a whole. In this way, the commercial diving industry as a whole will be in a better position to compete in Singapore as well as in regional and international markets.

As there are many different sectors of commercial diving in Singapore – for example, ship husbandry, shipyard works, marine salvage, marine engineering and inland utilities – what constitutes “industry best practices” will vary from company to company, based on each companies own operations and risk assessments. However, CDA(S) requires that each member company carries out diving work in compliance to the “Singapore Standard SS 511: Code of Practice for Diving at Work” issued by the Singapore Standards Council, as a minimum or baseline standard. It is upon this minimum level of compliance that each company can build upon by implementing the specific best practices which are most suitable for their operations.


A major pillar for the CDAS is to champion safety and health by studying best practices and train the workplace. The current executive committee comprises:

Singapore Safety Standards

Central to our mission in the Commercial Diving Association (Singapore) is to uphold safety standards for the industry and to champion best practices in safety. The Association does not work in isolation but under the authority and auspices of the Singapore Ministry of Manpower and the Workplace Health & Safety Act 2006.


In relation to commercial diving, this approved code of practice is contained within SS511; for Singapore Standards. These are nationally recognised documents established by consensus. They are functional or technical requirements in the form of specifications for materials, product system or process, codes of practice, methods of test, terminologies, guides etc.

There are also Technical References or TR for short, which are fast track documents developed to help meet urgent industry demand for specifications or requirements on a particular product, process or service in an area where there is an absence of reference standards. Unlike Singapore Standards, TRs are issued without going through the full consensus process as the time taken could affect the relevance to market needs. As such, they are made available for provisional application over a period of two years, but does not have the status of Singapore Standards. The aim is to use the experience gained to modify the TRs before they can be adopted as Singapore Standards.
