Dawane segararantai jangkardiukur ing "knot". China nemtokake manawa dawa standar saben rantai jangkar yaiku 27,5m. Negara-negara sistem Inggris biasane njupuk 15 ton minangka simpul, sing diwatesi nganti 27,5m nalika diowahi dadi meter. Sawetara njupuk 25m lan 20m minangka bagean.
Rantai jangkar laut sing lengkap kasusun saka tautan pungkasan jangkar, tautan tengah lan tautan pungkasan. Saliyane link chain karo swivels, jumlah chain link saben chain anchor kudu aneh kanggo mesthekake yen nalika nyambungake chain link utawa nyambungake shackles liwat sprocket windlass, padha bisa ngapusi warata ing soket sprocket lan pass. lancar.
Dawane bagean siji saka rantai jangkar asale saka unit Inggris 'fathom', utawa 'tuo', yaiku unit dawa unik sing digunakake ing segara. Siji bagean saka rantai jangkar kira-kira 1,8288 meter, sing dawane lengen wong (mesthi wong Eropa putih) nyebar. Siji bagean saka rantai jangkar njupuk 15 bagean, yaiku, luwih saka 27,43 meter. Nalika diowahi dadi sistem metrik, mantissa dibusak lan 27,5 meter dijupuk langsung. Dadi wis diterusake karo konvensi.
Umume, kanggo outfitting, dawa rantai jangkar L dipilih miturut nomer outfitting N. Siji rantai jangkar dawane 27,5M. Nalika L dipilih miturut nomer outfitting punika malah kaping 27,5M, rantai anchor kiwa lan tengen padha dawa. Nalika iku macem-macem aneh, sisih starboard 27,5 maneh saka sisih port. Secara pribadi, aku mikir bisa uga ana hubungane karo jangkar ing pelabuhan. Umumé, misale jek sing dermaga port port lan chain anchor tengen dibuwang kanggo posisi. Bisa kanggo ngukur ambane banyu ing starboard, supaya chain jangkar kudu siji dawa!
Generally, the anchor chain of a ship is 27.5 meters long, and each anchor is equipped with 10 to 11 anchor chains. It is only about 300 when all the anchor chains are sent down. Therefore, the anchoring is generally about 30 meters deep in shallow water, and the anchor chain will work only if there is friction force under the anchor chain, while the anchoring location is generally in the special anchorage planned by the port authority!
