Why 4Subsea?



We are a team of highly dedicated (and slightly geeky) engineers, redefining how oil & gas fields and offshore wind farms are operated.


We combine our operational experience with digital capabilities to automate engineering processes and help operators reduce risk and cost.


Our decision support solutions help operators “know it before it happens”. This way, they can act accordingly and prevent costly repairs or production shutdown.


The company has been steadily growing since the beginning, both in terms of turnover and number of employees.  4Subsea now has more than 65 employees, supported by a number of experienced expert consultants. Our staff consists of highly qualified chartered engineers with a unique blend of theoretical and practical experience within subsea technology.

With growing complexity comes more demanding challenges. In 4Subsea we apply our knowledge to systemise and industrialise our solutions making them applicable on a large scale. We believe in sharing ideas, resulting in improved processes and solutions, which collectively will move us forward as an industry.

Why 4Subsea? Working alongside many very knowledgeable and inspiring colleagues. Making good use of my special subject at university, which was the area of intersection between marine technology and ICT. Opportunities to travel offshore and see how the data we process gets used! Solving challenging problems with dedicated and knowledgeable colleagues.
