Voluntary thickness addition is the thickness that is voluntarily added by the owner or builder as extra margin against corrosion wastage, beyond what is required by the applicable rules. Voluntary stiffener web thickness addition. Voluntary thickness addition is the thickness that is voluntarily added by the owner or builder as extra margin against corrosion wastage, beyond what is required by the applicable rules. is defined as the minimum design normal ballast draught amidships (measured in meters). At this draught, the strength requirements for the ship's structure are met. It represents the minimum draught of any ballast condition in the loading manual, and covers both departure and arrival conditions. The idealised moulded centre of gravity of the structure part. The idealised moulded dry weight of the structure part. The physical volumetric dry weight of the structure part The physical volumetric mass centre of gravity of the structure part. An elliptical hole. Type definition of a parametric Ellipse The flange renewal thickness of the profile. Renewal thickness refers to the minimum allowable flange thickness, below which steel renewal must be carried out. The web renewal thickness of the profile. Renewal thickness refers to the minimum allowable web thickness, below which steel renewal must be carried out. High-strength, corrosion-resistant alloy commonly used in marine, aerospace, and structural applications The alloy according to e.g. the International Alloy Designation System (AA) A reference to the associated alloy standard. Yield strength of the base material before welding. Yield strength. Properties after welding, where strength typically decreases due to thermal effects. The maximum stress the material can withstand before breaking. Properties of the base material before welding. The maximum stress the material can withstand before breaking. Properties after welding, where strength typically decreases due to thermal effects. A mid-point on the contour boundary defined by an intersecting surface. The mid-point is needed to identify the correct contour segment if the intersection results in a closed contour. For multiple surface solutions, a point on the target surface must be provided. The orientation rule for the stiffener. The rule is used to orientate the stiffener together with the Inclination. The stiffener Inclination determines the orientation of the flange and the web side. The stiffener is mounted with the WebDirection normal to the the global YZ-Plane. The Inclination WebDirection determines if the stiffener is monted in the positive or negative direction. The Inclination FlangeDirection gives the flange orientation and the web material side. The stiffener is mounted with the WebDirection normal to the the global XZ-Plane. The Inclination WebDirection determines if the stiffener is monted in the positive or negative direction. The Inclination FlangeDirection gives the flange orientation and the web material side. The stiffener is mounted with the WebDirection normal to the the global XY-Plane. The Inclination WebDirection determines if the stiffener is monted in the positive or negative direction. The Inclination FlangeDirection gives the flange orientation and the web material side. The Inclination determines both the exact web direction, flange orientation and the web material side. The stiffener is mounted with the WebDirection “Twisted” along the Traceline. The Inclinations give the twist orientation vector along the length of the stiffener. It is assumed that the twist varies linearly along the length of the stiffener's trace-line between inclinations. The stiffener is mounted with the WebDirection normal to the mounting plane. The Inclination WebDirection determines if the stiffener is monted in the positive or negative direction. The Inclination FlangeDirection gives the flange orientation and the web material side. The direction of an offset from a reference object. The direction is only interpreted if a non-zero Offset is given.
