Anchor Strap Tensions using Tributary Volume The anchor strap tensions are calculated based on an effective tributary volume for each strap. This volume is calculated as half the distance to the adjacent strap on each side or to the end of the adjacent end cap for the first and last straps . The tensile force resulting from the riser volumes are distributed to the straps on each side of the riser based on the position of the riser. If the total buoyant force resisted by the anchor pad or deadmen with water to grade is negative , each buoyant tributary volume will still be calculated for each strap position. Depending on the size and location of the manways , risers , and the strap locations , some straps may be under tension and some may not as represented by positive and negative values respectively. Anegative strap tension indicates no tension on that strap no matter the magnitude of the negative value .
