Å<strong>ABS</strong> <strong>Notations</strong> and Symbols – 3 November 2003 (Updated on 25 January 2007)<br />
Common <strong>Notations</strong> and Symbols<br />
NOTATION<br />
SH<br />
DESCRIPTION<br />
SafeHull (SH) – The SafeHull notation is assigned to Oil or Fuel Oil Carriers, Bulk or Ore Carriers,<br />
Combination Carriers and Container Carriers designed to Part 5C, Chapters 1, 3 and 5 <strong>of</strong> <strong>the</strong> <strong>ABS</strong><br />
Rules for Building and <strong>Class</strong>ing Steel Vessels, respectively. Also, <strong>the</strong> SH notation may be assigned to<br />
Membrane Tank LNG Carriers designed in accordance with <strong>the</strong> <strong>ABS</strong> Guide for Building and <strong>Class</strong>ing<br />
Membrane Tank LNG Vessels. The SH notation applies to Container Vessels over 130 m, Bulk<br />
Carriers, Oil Carriers and Membrane Tank LNG Carriers over 150 m in length and Liquefied<br />
Petroleum Gas Carriers with Type-A Independent Tanks over 90 m in length. The requirements <strong>of</strong><br />
<strong>the</strong>se portions <strong>of</strong> <strong>the</strong> Rules are collectively referred to as <strong>the</strong> SafeHull Criteria. Although <strong>the</strong>se Rules<br />
contain a simplified approach to dynamic-based engineering evaluations, <strong>the</strong> <strong>ABS</strong> SafeHull computer<br />
s<strong>of</strong>tware system has been developed to perform <strong>the</strong> required calculations in <strong>the</strong> SafeHull Criteria. The<br />
SafeHull s<strong>of</strong>tware system is available through <strong>ABS</strong> plan approval <strong>of</strong>fices.<br />
The SafeHull Criteria is fur<strong>the</strong>r broken down to two distinct parts as follows, both parts are to be<br />
applied in order to receive <strong>the</strong> SH notation.<br />
Section 4 (Phase A): Specifies <strong>the</strong> initial minimum strength requirements for hull structure with<br />
respect to <strong>the</strong> determination <strong>of</strong> initial scantlings.<br />
Section 5 (Phase B): Assesses <strong>the</strong> adequacy <strong>of</strong> <strong>the</strong> structural configuration and <strong>the</strong> initial<br />
scantlings determined in Section 4 using finite element method (FEM) analysis.<br />
