Riser Base Jumper VIV Analysis
RiserTec Scope of Work –
- Initially assisting the Petrobras engineering team to asses technical feasibility of field development alternatives for the Riser System
- Detailed assessment of pipeline buckling & ‘walking’ potential
- Support to project team during detailed design. Particularly for design of RBJ for current VIV which was critical. This involved taking the contractors detailed design proposal & using RiserTecs in house VIV assessment program coupled with Orca flex optimising software running in Matlab, to propose a revised feasible design. The design improvement achieved a reduction in fatigue damage of approximately 10
- RiserTecs unique software; RT VIV, performed 3D analysis of combined in-line and cross-flow VIV on the jumper

Deep Water Riser
RiserTec has been involved in the engineering and design of a new subsea system intended to harvest critical base metal nodules from the seafloor. RiserTec's involvement over the period of around 1 year so far has mainly been in the global analysis & fatigue analysis of the lifting system that will carry the nodules from the seafloor to surface, with its main component being a 4.5km riser. The nodules contain high grades of nickel, manganese, copper and cobalt - key metals required for building electric vehicle batteries and renewable energy technologies.

MWA Tether Padeye Replacement
RiserTec was involved with the engineering and design of a replacement MWA tether base padeye for a major north sea operator, and the operation of replacing this component in-situ within the riser system at several site locations. The original component had suffered from fatigue damage as predicted in an earlier assessment, requiring a new billet component to be designed and installed. Extensive analysis work was carried out in order to identify the optimum method of replacing this component, before designing and fabricating temporary tether point structures to use in the replacement operation.

Wind Turbine Platform Wave Tank Testing
An offshore wind turbine support structure conceived by RiserTec has entered the model testing phase. A 1:50 scale model of the Fixed TLP (FTLP) concept has been tested under operational and extreme wind and wave conditions. Test data is being processed for system evaluation and to support future optimisation before progressing to the next stage of the design process. The final design is planned to support a 15MW wind turbine in water depths up to and exceeding 100m.

Rare Metal Nodule Collection
Nodules rich in rare metals required for electrical batteries have been collected from the sea floor through a 4.5 km long riser designed and analysed by RiserTec. 14 tonnes of nodules were collected from the sea floor and delivered to the production vessel during a 60-minute trial of the system. RiserTec’s role was global riser analysis and fatigue performance assessment.
