A word from the founder
With more than ten years of experience in the marine and subsea industry — as a field engineer, operations director and professional commercial diver — I have learned one essential thing: the success of an operation depends as much on preparation as on execution.
That is why I founded CREOSEA: an expertise company that puts engineering rigour and field experience at the service of your marine, subsea, offshore and port projects. We mobilise the right skills, partners and resources for each operation, with one constant requirement: protecting our clients' interests, the safety of the teams and the quality of the works.
