RE: Triton - rust bucket16 Oct 2025 08:46
Don't think folks realise the timeline for removing and deploying a new FPSO. Not only will you have to modify whatever replacement FPSO considered - if feasible but remove the Triton during a summer campaign. Shut in all fields, flush risers and apply isolations, lower all dynamic risers, disconnect moorings and tow away
Unfortunately the design of FPSO mooring and dynamic riser latching systems are all uniquely different with advances over the years. If only all turrets were of a similar design !!! From memory the dynamic risers on Triton are deployed and pulled in with the onboard turret winch, with a bend stiffener that divers bolt to the turret before the rise is fully pulled in through the I tubes into the FPSO. Disconnection is a reversal, all going well.
Moorings are again all different and again from memory the Triton moorings are latched onto the Turret Spider and not pulled into the turret .
Going forward - fix the Triton!!!!!!!!!
Or you could purely remove Triton, remove risers and moorings and get Subsea7 or Technip to design and deploy a mooring and riser system compatible with the new FPSO . anything regarding new FPSO is a long timeline and cost.
