Abstract

The Submerged Hanging Hollow Damper (SHHD), which is defined to be a type of Inertial Hydrodynamic Based Dampers, is to be able to damp floating objects based on inertial or hydrodynamic forces when being hung underneath water surface. The SHHD is developed in different versions based on inertial or hydrodynamic forces. A type of hanging rope structure, the SHHD Net-Bag, which is required for the SHHD, is also included.

Description

DESCRIPTION
A Submerged ballast comprises a vertical stack of used vehicle tyres (#18) being
stacked together from top to bottom in order from largest diameter to smallest
diametertoform an inverted cone shape. The stack is encapsulated within a rope net
cage comprising vertical strand (#16) and horizontal strand (#15). The rope net is
connected to a single ascending line (#7) above the top of the stack suitable for
connecting to an above waterline floating object. Water (#6) can enter and exit the
tyres opening at the top or at the bottom (#1) of the stack.
The tyres can also be randomly putted together and encapsulated by the rope net
cage.
DESCRIPTION
1.1 Definitions of the Inertial Hydrodynamic Based Damper (IHBD) and the Submerged
Hanging Hollow Damper (SHHD)
[0194] Inertial Hydrodynamic Based Damper is a damper based on inertial and
hydrodynamic forces for damping. Submerged Hanging Hollow Damper (SHHD) is a
(hollow) damper that is hung and submerged in water. The SHHD is a type of the IHBD
as it is able to generate inertial and hydrodynamic forces for damping.
1.2 The Submerged Hanging Hollow Damper (SHHD) (Figure 1 to Figure 6)
[0205] The word "rope" here implies both "rope" and "cable" capable to bear
tensional forces.
[0206] The SHHD is applied for floating structures or systems of floating objects,
including floating energy systems of wind, wave or solar, particularly wave energy
systems. As a damper capable to resist upward motions, it helps to separate motions
of rotors and stators from every single wave, leading to generating electricity. It also
helps to stabilize floating structures.
[0207] The SHHD is defined to be a type of Inertial Hydrodynamic Based Dampers with
hollow body. It is integrated in and applied for the MASHHD (the Method of Applying
Submerged Hanging Hollow Damper). The purpose of the development of the SHHD is
to provide damping efficiencies and anchoring to floats (Stationed Floats), which hang
the SHHD via ropes or cables. The floats (Stationed Floats) are positioned close to
water surface while the SHHD is being hung in deep water underneath, where waves
are much less. Thus, the main common technical features of all types of SHHD
classified below is to be able to damp floating objects based on inertial or
hydrodynamic forces when being hung underneath water surface.
[0208] The principle of SHHDs working in water similar to that of parachutes working
in the air.
