A practical cavitator design method for straight-running-type supercavitating torpedoes was developed in this paper. Design requirements were first drawn in terms of torpedo performance characteristics, such as maximum range and motion stability. This method determines the optimum cavitator satisfying the design requirements that not only minimize the total drag of the torpedo, extending the maximum range, but also provide hydrodynamic forces required for straight level flight. The design procedure includes determining a design cavitation number and cavitator type (disk or cone) for obtaining

Abstract Torpedo anchors are dynamically installed anchors for the mooring systems of floating platforms and received the name of "torpedo" due to the cone head and the fin tail. Commonly used torpedo anchors have a diameter of around 1.0m (typically between 0.7 to 1.3m) and a length-to-diameter ratio of less than 20. During an offshore installation, the anchor will be lowered down to a height from the seabed about 50-100m. Once released from the releasing mechanism, the anchor will fall through the water column and penetrate into soil reaching the target depth within 10s. The target embedment

Abstract Torpedo anchors represent a promisingly innovative anchorage foundation for deep water applications due to their efficient and economical installation. During installation, a significant length of mooring chain was embedded into the seabed alongside the torpedo anchor. This interaction between the chain and the soil alters the strength characteristics of the clay, and also affect the loading angle at the padeye during pullout. As a result, the bearing capacity of the torpedo anchor is influenced by the movement of the chain. However, existing numerical studies lack a comprehensive und

Abstract:
On deep water applications the mooring lines can be held in place by VLA (Vertical Load Anchoring) systems. This is to avoid a too large anchoring radius. An alternative that has been used is the so-called torpedo anchor. The name torpedo comes from its installation, and is, in fact, a pile with side fins that improve the anchoring properties by soil friction. However, these fins are far ahead from the pile mid-section which leads to an unstable situation during launching through the water, when the pile is released 100 m from the sea bottom. The kinetic energy at the touch point on the bottom
