. The CEL 100K propellant anchor : utilization for tanker moorings in soft coral at Diego Garcia. Deep-sea moorings; Anchors; Marine engineering; Civil engineering. Figure 5. Rear of fluke, showing base plate and holes for shear pins. MOORING DESIGN Moorings were required on an intermittent to frequent basis for the offloading of POL from tankers. The permanent moor was designated for use by tankers up to and including the AOE-1 SACRAMENTO Class 53, 600 dead weight tons displacing (dwt) (54, 500 metric tons), whereas the temporary moor was limited to the AO-143 T5 Class, displacing 38, 000 dwt (38, 600 metric tons). A four-point spread mooring was required at each site in order that ships would remain relatively stationary while offload- ing fuel into installed submarine pipelines. The moorings were required to be maintained in winds up to 27 knots (14 m/s) with gusts up to 36 knots (19 m/s) and with currents up to 0.5 knot (0.26 m/s) from any direction. In this environment, the maximum forces imposed on a mooring buoy by the vessel in a four-point spread mooring were determined by Fluor Corporation (1973) to be 152, 000 pounds (680 kN) for the AOE-1 and 115, 000 pounds (510 kN) for the AO-143. It was required that these moorings be anchored at sites having variable coraline seafloors. Site conditions were reported by opera- tional personnel and confirmed by diver reconnaissance to be coral heads and coral overlain by a loose gravel/sand/silt sediment at the permanent site, and bare coral at the temporary site. The installed conventional drag-burial anchors at the temporary site were not embedded and were visible on the seafloor surface, showing signs of having been dragged without becoming buried. Standard penetration tests conducted in the 8.
