SLP Interface
Issues/Observations
• Each scenario is different based on the type of watercraft, type of sealift ship, mooring position, and RRDF configuration and location relative to ship.
• Heave is most sensitive motion for watercraft (not roll).• Lighter maneuverability and seakeeping varies with lighter type.• Current fenders are not SS3 capable due to rupture, damage, and failure;
gap between fenders; and size variations may not support ops ( i.e., fenders roll onto low freeboard craft).
• Short mooring pendants cause snap loading and potential danger.• Difficult to capture pendants with boat hooks.
