Viking Seatech has the global expertise and technical acumen to ensure your anchoring is as efficient as it can be. The size of an anchor is generally referred to by its weight in air. Anchor holding power is determined by the anchor's efficiency multiplied by its weight. The efficiency of the anchor is determined by design, testing and the type of soils in which the anchor will be expected to perform. As the size of an anchor is increased, its efficiency decreases. A concrete sinker has an efficiency of approximately 0.5:1 whereas modern specialist anchors can have efficiencies up to 100:1 depending on soil conditions. Speak to Viking Seatech. We can help determine the optimum weight to efficiency for your operation.
