Empowering underwater technology since 1978 

Ever since the company was founded in 1978, connectivity has held a special place at the core of the increasingly system oriented MacArtney organisation. Even today, connectors, cables, terminations, junction boxes and everything beyond and in between, are involved in pretty much everything that we do and in many ways, it is connectivity and integration that has paved - and still paves - the way for most other innovative MacArtney products and systems. 


Connectivity for everyone, everything and everywhere 

MacArtney designs and manufactures state-of-the-art connectivity for any application within all maritime industries including subsea, offshore oil and gas, marine renewables, ocean science, civil engineering, defence, fisheries and diving. Key technologies include wet and dry mateable power, signal and optical connector solutions, terminations and penetrators, under the renowned SubConn®, TrustLink and OptoLink brands, GreenLink termination solutions and subsea cables from leading manufacturers. Besides this, MacArtney supplies an endless list of custom connectivity solutions including special moulded or machined cable assemblies, bespoke interconnect solutions and junction boxes. All MacArtney connectivity solutions are designed, built and tested for use under extreme conditions and have established a track record of uncompromised reliability in harsh marine environments.
