<p>This document specifies requirements for managing and controlling the weight and centre of gravity (CoG) of offshore facilities by means of mass management during all lifecycle phases including; conceptual design, front end engineering design (FEED), detail engineering, construction and operations. These can be new facilities (greenfield) or modifications to existing facilities (brownfield).</p>
<p>Weight management is necessary throughout operations, decommissioning and removal to facilitate structural integrity management (SIM). The provisions of this document are applicable to fixed and floating facilities of all types.</p>
<p>Weight management only includes items with static mass.</p>
<p>Snow and ice loads are excluded as they are not considered to be part of the facility. Dynamic loads are addressed in ISO 19904-1, ISO 19901-6 and ISO 19901-7.</p>
<p>This document specifies:</p>
<p>a) requirements for managing and controlling weights and CoGs of assemblies and entire facilities;</p>
<p>b) requirements for managing weight and CoG interfaces;</p>
<p>c) standardized terminology for weight and CoG estimating and reporting;</p>
<p>d) requirements for determining not-to-exceed (NTE) weights and budget weights;</p>
<p>e) requirements for weighing and determination of weight and centre of gravity (CoG) of tagged equipment, assemblies, modules and facilities;</p>
<p>This document can be used:</p>
<p>f) as a basis for costing, scheduling or determining suitable construction method(s) or location(s) and installation strategy;</p>
<p>g) as a basis for planning, evaluating and preparing a weight management plan and reporting system;</p>
<p>h) as a contract reference;</p>
<p>i) as a means of refining the structural analysis or model.</p>
