Abstract: |
The longstanding tradition of using lines to moor ships to docks is inherently labor intensive and hazardous. Synthetic line snapback, limbs caught in rigging, as well as failed deck fitting projectiles, have maimed and killed many shipboard and dockside personnel over the years. Likewise, the challenges associated with shortening, slacking, doubling up and singling up lines to adjust for changing environmental conditions requires substantial human vigilance. Without this attention, lines and/or bitts can become overloaded due to tension loads applied, often at excessive angles. Automated methods have replaced many such manpower intensive systems in other modern day systems. Navy harbor facilities accommodate a very wide range of ship sizes and shapes from large sealift and amphibious ships to, to trimarans, to cylindrical hull shaped submarines. An automated mooring system will be developed that mitigates the hazards associated with mooring lines, while accommodating a larger variety of ship sizes and types than what can be with current commercially available automated systems. |
Benefits: |
The proposed system will provide all the safety features of existing commercial systems, and more. Existing systems provide for Dock Master monitoring of environmental conditions, mooring loads, alarms, etc. These systems also include benefits of failsafe features, ships being moored closer together, quicker mooring process savings on harbor tug time, and of course, no shipboard or dockside line handlers needed. In addition, the proposed system will provide additional mooring wherever needed along the dock to address all variances in ship types, sizes and shapes, as well as for adding additional units during extreme weather. And, when not in use, the system will be stored and maintained out of the weather. |
