Deepwater anchors, typically the suction embedded plate anchor (SEPLA) and the OMNI-Max anchor, would encounter the phenomenon of embedment loss after initial penetration, which remarkably reduces the pullout capacity and affects the subsequent behavior of the anchor. Therefore, the maximum embedment loss (MEL) becomes a key index for design and engineering practice. Based on the mechanical mechanism and kinematic property of anchors, a unified explicit formula for calculating the MEL of SEPLAs and OMNI-Max anchors in clay, in terms of the anchor geometry, interactional property, soil condition, anchor line property and applied loading, is developed by combining theoretical models and nonlinear fitting analyses. The efficiency and precision of the formula are validated by experiments and other available methods. Compared to existing methods, the proposed formula provides a simple tool for fast assessing the MEL of both SEPLAs and OMNI-Max anchors in clay, and performs superiorly in easiness, efficiency and applicability.

深水锚，典型的吸力埋入式板锚（SEPLA）和OMNI-Max锚，在初穿后会遇到埋入损失现象，显着降低拉拔能力，影响锚的后续行为。因此，最大嵌入损失（MEL）成为设计和工程实践的关键指标。基于锚杆的力学机理和运动学特性，从锚杆几何形状、相互作用特性、土壤条件、锚线特性和外加载荷等方面，计算粘土中SEPLAs和OMNI-Max锚杆的MEL的统一显式公式为通过结合理论模型和非线性拟合分析开发。通过实验和其他可用方法验证了公式的效率和精度。与现有方法相比，
