All are used less often than Panama Chocks. NS standard mooring pipe is more often used in European countries than in Asia.So on ships made in Euro, we can find this type of chocks more. Most commercial ships now are fabricated in Asia countries such as Japan, Korea, China, Phillipine,etc. So NS Standard seldom appears on most ocean sailing ships. It doesn't mean we can't manufacture them according to your request.All of them can be manufactured with class certificate of CCS, DNVGL,KR,LR,NK,ABS,etc.
