Products & Services


Aquamarine offers its customers a complete service center for the manufacturing, modification, maintenance, re-certification and repair of riser and riser related equipment. Aquamarine performs inspection and repair of complete riser systems, in cooperation with leading OEMs.

Knowledge is power, and Aquamarine knows risers

This understanding, honed through extensive repair services with work over risers, production risers and drilling risers, has enabled us to confront a major issue within the industry – the time consuming nature of riser repair and the difficulties of extending lifecycles.

Aquamarine’s expertise and commitment to innovation has empowered an industrial breakthrough. We have developed a new process for work over risers based on thermal coating, utilising tungsten carbide and Inconel 625 coatings to significantly reduce the cost of maintenance.
