About Us

Oceandivers Ltd (trading as TC Marine) are specialists in diver training and associated marine safety training programmes. Brian Murphy and William Siddall founded the first Professional Association of Diving Instructors training school in Ireland in 1989. Since then, we have continued to deliver quality diver training courses and developed a number of specialised training programmes including the first ever Commercial Diving courses run in Ireland for Bord Iascaigh Mhara in 1993 and approved by the UK Health and Safety Authority and subsequently the National Council for Vocational Awards. These programmes were successfully delivered for BIM over the following ten years. 

In 2018, Oceandivers Ltd in association with BIM and QQI, developed the QQI Level 6 Commercial Scuba Diving Operations and Surface Supplied Inshore Diving Operations award specifications. Subsequently, Oceandivers Ltd developed the programmes to meet those standards and successfully guided these through the QQI Validation process.

We have worked with the Health and Safety Executive in the UK to have the QQI/BIM diving programmes recognised thus ensuring international recognition for BIM divers' qualifications. We have also worked as members of both the European Diving Technology Committee, a requirement under the HSE recognition scheme, and also the International Diving Schools Association

Since its conception, Oceandivers Ltd have worked with a number of government agencies in Ireland and the UK including the Health and Safety Executive (UK) and the Health and Safety Authority Ireland. Brian Murphy has a background in Saturation Diving working offshore in the oil and gas industry as well as diving inshore on marine civil engineering projects and aquaculture sites. Within the company his role includes commercial diving projects, advanced and technical diver training, power boat training and boat operations.
