Project management and supply

Semco Maritime works as a turnkey contractor (EPCI) and subcontractor. We certify our project managers according to Internationally recognised standards, and constantly improve our tools ensuring a seamless project execution with maximum control of the project at all times – from baseline to baseline.

To support the project manager in controlling the many elements, of the EPCI projects, we train and develop engineering-, construction- & installation managers, each with their specialities in the different phases of the project. 

Procurement is an integrated part of our project execution model, supporting our project organisation in all phases of the project. Through clear roles and responsibilities we ensure that each element is carefully integrated to form the overall and complex functionalities specified by our customers.

Experienced people dedicated to your industry

Our engineers, technicians and operators are trained in health and safety for the oil and gas industry. They have experienced the harsh conditions onboard platforms first-hand, so they understand your offshore operations – and the challenges your crew face working in some of the world’s toughest maritime environments. When your oil and gas assets need maintenance or require modifications, we will use our experience to find the safest, most beneficial solutions with minimum downtime.
