About us

Transmark Subsea was established in 2009 as part of Transmark Holdings

Over the years we have jointly developed subsea solutions in close cooperation with our customers, delivering equipment that has been installed at subsea sites of many major end users. Tailor-made monitoring and surveillance systems and smart connection solutions are a few of the many developments we contribute to our customers’ success. Transmark Subsea designs, produces and performs thorough testing which eliminates costly and complex production challenges and ensures a working, qualified end-product ready to be installed. Next to our engineering capabilities we have a large assortment of standard products in stock available for immediate delivery.

Transmark Subsea is based in Bergen, Norway and in Aberdeen, Scotland the two centers of advanced Subsea engineering in Europe.

With the increasing customer demand of flexibility and short lead times, Transmark Subsea has adjusted our organization to cope with this development. With our own sophisticated workshop and team of engineers we are able to develop, manufacture and deliver solutions in record lead times, leaving customers pleasantly surprised and their projects on-schedule.
