강풍에 묘박중인 선박에서 파단하중 계산하는 방법 문의

대만 MAILIAO외항 수심 21M에 좌현묘를 투하하고 묘쇄를 8 SHOTS 신출하였는데 갑자기 불어온 35KTS 강풍에 견디지 못하고 ANCHOR COMMON LINK가 절손된 사건이 발생하였습니다. COMMON LINK는 재질이 압연봉강으로서 유첨 사진에서와 같이 절손된 원인이 35KTS 강풍에 파단 하중을  견디지 못하였다는것은 이해가 가지 않습니다.   좀더 이론적으로 파단하중 계산방법을 가르쳐주시면 감사 하겠습니다.   DWT 15K, LOA 150M, B: 22M, BALLAST CONDITION : DF: 4.3M, DA: 5.5M, 저질: 모래 <A name="[문서의 처음]"></A> <A name=#425a6aca></A> <TABLE style="BORDER-BOTTOM: medium none; BORDER-LEFT: medium none; BORDER-COLLAPSE: collapse; BORDER-TOP: medium none; BORDER-RIGHT: medium none" border=1 cellSpacing=0 cellPadding=1> <TBODY> <TR> <TD style="BORDER-BOTTOM: #000000 0.4pt solid; BORDER-LEFT: #000000 0.4pt solid; BORDER-TOP: #000000 0.4pt solid; BORDER-RIGHT: #000000 0.4pt solid" height=25 vAlign=center width=694 colSpan=6> CHAIN </TD></TR> <TR> <TD style="BORDER-BOTTOM: #000000 0.4pt solid; BORDER-LEFT: #000000 0.4pt solid; BORDER-TOP: #000000 0.4pt solid; BORDER-RIGHT: #000000 0.4pt solid" height=25 vAlign=center width=171> ARTICLE </TD> <TD style="BORDER-BOTTOM: #000000 0.4pt solid; BORDER-LEFT: #000000 0.4pt solid; BORDER-TOP: #000000 0.4pt solid; BORDER-RIGHT: #000000 0.4pt solid" height=25 vAlign=center width=133> TYPE </TD> <TD style="BORDER-BOTTOM: #000000 0.4pt solid; BORDER-LEFT: #000000 0.4pt solid; BORDER-TOP: #000000 0.4pt solid; BORDER-RIGHT: #000000 0.4pt solid" height=25 vAlign=center width=68> QUANTITY </TD> <TD style="BORDER-BOTTOM: #000000 0.4pt solid; BORDER-LEFT: #000000 0.4pt solid; BORDER-TOP: #000000 0.4pt solid; BORDER-RIGHT: #000000 0.4pt solid" height=25 vAlign=center width=99> CAPACITY </TD> <TD style="BORDER-BOTTOM: #000000 0.4pt solid; BORDER-LEFT: #000000 0.4pt solid; BORDER-TOP: #000000 0.4pt solid; BORDER-RIGHT: #000000 0.4pt solid" height=25 vAlign=center width=91> MAKER </TD> <TD style="BORDER-BOTTOM: #000000 0.4pt solid; BORDER-LEFT: #000000 0.4pt solid; BORDER-TOP: #000000 0.4pt solid; BORDER-RIGHT: #000000 0.4pt solid" height=25 vAlign=center width=133> REMARKS </TD></TR> <TR> <TD style="BORDER-BOTTOM: #000000 0.4pt solid; BORDER-LEFT: #000000 0.4pt solid; BORDER-TOP: #000000 0.4pt solid; BORDER-RIGHT: #000000 0.4pt solid" height=38 vAlign=center width=171> ANCHOR CHAIN(PORT) </TD> <TD style="BORDER-BOTTOM: #000000 0.4pt solid; BORDER-LEFT: #000000 0.4pt solid; BORDER-TOP: #000000 0.4pt solid; BORDER-RIGHT: #000000 0.4pt solid" height=38 vAlign=center width=133> ELECTRICALLY WELED STUD LINK CHAIN </TD> <TD style="BORDER-BOTTOM: #000000 0.4pt solid; BORDER-LEFT: #000000 0.4pt solid; BORDER-TOP: #000000 0.4pt solid; BORDER-RIGHT: #000000 0.4pt solid" height=38 vAlign=center width=68> 55mm*10 </TD> <TD style="BORDER-BOTTOM: #000000 0.4pt solid; BORDER-LEFT: #000000 0.4pt solid; BORDER-TOP: #000000 0.4pt solid; BORDER-RIGHT: #000000 0.4pt solid" height=38 vAlign=center width=99> 1589KN </TD> <TD style="BORDER-BOTTOM: #000000 0.4pt solid; BORDER-LEFT: #000000 0.4pt solid; BORDER-TOP: #000000 0.4pt solid; BORDER-RIGHT: #000000 0.4pt solid" height=132 vAlign=center rowSpan=4 width=91> JIANGSU ASIAN STAR ANCHOR CHAIN CO.
