... mooring. The temporary Serpentina FPSO moorings (2013 - 2019) included an HMPE mooring rope in each of the 9 mooring lines. All ~350 ft length ropes were located at and under the mudline as forerunners to a drop-embedded anchor. The mooring lines were recovered in 2019 and stored quayside in Louisiana...
