Navy ships experience rapid wear and chaffing of ship’s mooring ropes against the standard deck-edge chocks requiring that they be replaced every 18 to 24 months. To minimize this significant cost, Advanced Integrated Systems, LLC (AIS) proposes a new system of replaceable chock inserts – stainless steel covered by a low friction, non-corroding, long life coating. Phase I efforts include performing trade studies, identifying the appropriate performance requirements, developing test samples and performing computerized modeling. These efforts will result in a new chock design which is economical and commercially viable. The new coated chocks will be non-abrasive and will not contribute to the fouling of mooring lines. They will also withstand the forces imparted by the heaviest ship lines and remain unaffected by corrosive marine environments.BENEFITS: The successful chock and replaceable insert design will result in significant life cycle mooring line cost savings for the US Navy, US Coast Guard, and commercial shipping industry.
