Project description
Rig Engineering (RE) was tasked by XCITE Energy / Mooring Systems Limited (MSL) to undertake and provide all the necessary engineering and design services to take their feasibility study to conclusion. This feasibility study to flow the well, was done by XCITE and requires for the export hose and chute to be installed on column top of Semisubmersible, Ocean Guardian. RE provides global and local strength verification along with destruct and construction drawings of the supporting structures to accommodate all the equipments provided by XCITE Energy

R.E. Scope of work
R.E. escalates previous work done by XCITE Energy by doing structural layout at the candidate area and follows by strength verification of the rig side structure to absorb all the loads emanating from this prescribed specific loading regime. Bill of material (BOM) for the chute support foundation has been extracted from the model usedin this assessment and forward to XCITE contractor. BOM was needed at the same time as design being finalized to allow sourcing of the raw material and to have them shipped and ready for installation. This was done along with engineering’s recommended sketch showing sea fastening and connecting details to allow for the fabricator to develop fabrication and installation drawings on site
