Riser Delivery Management Complete riser engineering and delivery – optimised riser design, increased choice of hardware and improved system operability. 2H Offshore’s riser delivery management services are tailored to meet the needs of all project execution phases requiring detailed design, hardware procurement, fabrication management, inspection services, transportation/shipping management and installation support. Benefits of 2H’s System Integrator Approach We take the system integrator role on a project – an approach well-suited to riser systems that can have many interfaces with the well system and the host vessel, which tend to drive riser design and procurement activities. This approach allows for a more optimised design, increased flexibility in hardware selection, and improved operability. 2H is able to mobilise a multi-disciplinary project team that will define and control project activities for riser equipment that often has a high degree of project specification and typically presents the following challenges: Custom designed components that push the boundaries of manufacturing capability Multiple interfaces at the vessel and seabed Many cross-supplier interfaces to manage within the riser system Difficulty in finalising the design of all system components simultaneously Need for early purchase order placement because of long manufacturing lead times Need for follow on engineering to manage change and expedite delivery Riser & Package Engineering Our analysis and system engineering team ensures that the riser system global design meets every project’s functional and operational requirements. This team guarantees the riser system is installable, operable, reliable and maintainable. Our materials, welding and corrosion engineering specialists develop system specifications at the start of detailed design. Then, they provide technical support during procurement and fabrication as part of the follow-on engineering. Package and system engineers generate all documents specifying the requirements for the riser components or sub-assemblies. These documents form the technical package of the requisition issued to suppliers and the package engineers are subsequently involved in the technical bid reviews. They also oversee the equipment manufacturing phase – providing the follow-on engineering support required to review supplier documentation, manage design changes, and address supplier concessions and manufacturing non-conformances. Procurement Services 2H procurement services include complete commercial management of the equipment packages – pre and post-purchase order placement. We are able to procure equipment within a client’s purchasing system or by using our own in-house purchasing system. Our procurement services include: Pre-qualification of suppliers Preparation of request for quotation (RFQ) packages and their issue Terms and conditions negotiations Evaluation of prospective supplier bids Recommendation to award Issue of purchase orders Progress tracking and expediting of orders Management of supplier invoices and claims Shipping and logistics Purchase order close out Quality Control & Inspection Quality control and inspection services are fully integrated into the 2H project organization, allowing a seamless interface with the package engineering and procurement teams. This is particularly important for riser equipment packages that typically have the highest criticality level and have a high level of project specification.
