The towing force of a ship is much greater than that of its mooring line, so the lead line hole in the emergency towing belt generally bears a huge load directly.
In order to avoid the deformation or even fracture of the pilot cable hole during the use of the pilot cable hole, the ship can not work normally or even cause serious safety accidents. Therefore, our company carried out stress, strain and fatigue analysis for the cable guide hole to make improvement analysis.
Finishing requirement
To ensure sufficient adhession for surface treatment all sarp edges shall be rounded to minimum R2.5, welding spatter beadsd and slag shall be completely removed ,Damage in surfaces shall be filed and grinded flush, negative thickness measurements are prohibited
