Ramboll has more than three decades of experience with offshore infrastructure. We cover transmission pipelines as well as infield flow line systems, from concept to design. For maturing pipelines, we handle all aspects of brownfield-engineering related to the reassessment of structural integrity.
We design complex High Pressure/High Temperature (HPHT) flow lines, and we specialise in subsea tie-back projects with topographical challenges, combined with HPHT operation.
As a multidisciplinary international engineering and design company, we always set the best team for a given project and we can offer services for all phases of a project’s life cycle, from financial studies and impact assessments to construction management, fitness for reassessments and lifetime extensions.
Subsea design competencies
Our proven pipeline engineering competencies are based on an advanced understanding of critical issues such as structural behaviour and hydrodynamics under adverse conditions. We offer offshore expertise in route selection, geophysical and geotechnical route surveying, system optimisation, laying and trenching analysis, riser systems, flow assurance, subsea components and installation.
Ramboll provides a full set of subsea operation services in connection with subsea pipeline design. Our subsea engineering includes know-how regarding templates, subsea safety isolation valves (SSIVs), protection structures and Y and T assemblies.
Pipeline reassessments for maturing fields
Ramboll supports clients in increasing efficiency and prolonging production on mature fields. Our in-depth knowledge extends to offshore plat-forms and FPSOs, which gives us the required overview and experience to handle tie-back or tie-in projects for all relevant interfaces between pipeline, subsea completion and platform or FPSO.
Connecting to onshore infrastructure
Because of our multidisciplinary profile, Ramboll can also assist in connecting subsea highways with onshore infrastructure, by engaging our civil engineering experts, who are specialists within areas such as ports & marine, roads, construction and contract management.
