High Holding Power (HHP) Anchors

Characteristics:
As the name suggests, these anchors are designed to provide significantly greater holding power than conventional anchors of the same weight. They generally feature long, wide flukes that dig deep into the seabed for superior resistance .

Official Classification:

• HHP Anchor (High Holding Power): Must achieve a holding power at least twice that of a conventional stockless anchor of the same weight. This allows for a 25% weight reduction compared to standard anchors .
  
• SHHP Anchor (Super High Holding Power): Must achieve a holding power at least four times that of a conventional anchor. This allows for even greater weight savings 
  

AC-14 Anchor: A popular design with massive stabilizing fins. It offers excellent stability and rapid digging, with a holding power ratio reaching 12–14. Commonly used on超大型船 (very large vessels) and Ro-Ro ships

Delta Anchor / CJ-17 Anchor: A plow-shaped anchor with excellent penetration in various seabeds. The Stevpris (developed in the Netherlands) has a holding power ratio of 17–34, making it ideal for offshore platforms

Danforth Anchor : Features a stock at the crown and sharp flukes, achieving a holding power ratio of over 10. Often used on engineering vessels 

HHP anchors are critical for offshore and heavy-duty applications where performance is paramount.
