How do we add Value?Our engineering aims to deliver the most efficient solution, both technically and commercially, using our company QSHE standard. For example, for pipelay with a DP vessel we will try to work towards a low thrust level for fuel savings. This is done by a high level clearly laid-out step by step plan.
Key Deliverables:When pipelay is finished and the final connection has been made, the pipeline has to be tested. We can develop a pre-commissioning plan for the installed pipeline. This typically incorporates:
Failure can occur during installation or during service.
Contingency – Failure during Installation:The failures during installation can be due to equipment, material, human or third party failures or environmental conditions. We create Contingency Operations to be implemented in case of a failure. For example:
When the pipeline is in service the failures which can occur are material degradations, environmental conditions, risks and blockage. To mitigate these threats, Emergency Response Plans have to be developed before any such situations occur. These include:
Midline Tie-in or Above Water Tie-in (AWTI) is an operation where two laid down pipelines on the seabed are welded together after being lifted above water using vessel davits. For AWTI we determine/provide:
Static Code checks (pipeline integrity) are performed for every static loadcase. Dynamic Analysis is performed for the respective worst case in Pipe Recovery, Welded configuration and Laydown. DNV buckle checks are used to ascertain pipe integrity during dynamics.

End Deliverables:A Steel Catenary Riser (SCR) can be installed and be hung-off against a FPSO or directly to a platform.
For installation on platform, the SCR is either lifted or made buoyant to bring it to the Platform. Then it is handed-over and hung-off.
For installation on FPSO, the SCR can be lifted, handed-over and directly hung-off if FPSO is in position. Otherwise it can be pre-laid on the seabed. Once the FPSO is anchored on location, the pre-laid SCR(s) will be recovered, keel-hauled, handed-over and hung-off to the FPSO.
We can perform the analysis to ensure SCR is safely installated in all the aforementioned operations. We are also adept at writing procedures to be followed offshore for a safe and efficient installation.
