An anchoring assembly for securing a holding strap to a storage tank, the anchoring assembly comprising:

• a base that is connectable to a top surface of the storage tank, the base comprising a seat member extending upwardly from the top surface of the storage tank;
• and
• an anchor that is reversibly secured to the base and positionable in a transverse direction of the storage tank, the anchor comprising:
• a hook component being configured to anchor a proximal end of the holding strap;
• and
• a tightening mechanism that is connected to the hook component and being supported above the top surface of the storage tank by the seat member of the base, wherein the tightening mechanism is actuable to move the hook component with respect to the top surface of the storage tank, thereby modifying a tension of the holding strap.
