The first anchored unit (30) is on the deep side of the waterway and the second anchored unit (18) is on the shallow side of the same waterway. The shuttle floatation unit (10) moves freely between these two anchored units (30, 18).

Description

Description
SHUTTLE FLOATING JETTY USED AS A FERRY
Field of invention
[1] Shuttle Floating Jetty is a method of and a system for water crossing which is envi¬ ronmental friendly and simplicity in construction.
Background
[2] Jetties are required to allow marine vessels to moor and transfer passengers and goods to the shore. The length of a jetty is dependent on many factors especially on the conditions of the seabed and tide conditions. A seabed that is shadow and stretches far from shore would require a lengthy jetty to effectively allow a marine vessel to moor with sufficient depth of water.
[3] Construction of a long conventional jetty with wood, metal or concrete is costly, labour intensive and prone to environmental pollution. For ecological sensitive area, the construction can cause irreversible damage to the landscape and aquatic life. This is especially important to pristine island resorts that the marine life is the prime asset to attract tourists. Many islands are without jetty because of their affordability. Boats launched onto the shore and anchored on coral reef often caused severe damage to the aquatic life.Therefore, there is clearly a need for an ecological method of constructing a jetty without the foregoing disadvantages of conventional jetty construction process.
[4] Floating jetty is an excellent choice over conventional jetty built with traditional materials including wood, metal and concrete. Floating jetty that are made of durable plastics is friendly to the environment and can last for a long time. There is hardly any on-site construction since floating jetty consists of prefabricated floats. However, the cost of durable engineering plastics is high and a long floating jetty may still be expensive for many users to adopt readily. This invention arises from the need to preserve the advantages of the floating jetty and yet reduces its cost to allow wider adoption.
Summary of Invention
[5] According to an objective of the invention it is provided a shuttle floatation unit to ferry passenger across the water without having to build an entire length of floating structure. As a result, huge amount of material and hence construction cost is reduced. The shuttle floatation unit is guided by two anchored units where the first said anchored unit is an anchored floatation unit secured to the seabed to serve as the mooring platform on the deep end side of the water where marine vessels are moored for passengers and goods to be loaded and unloaded. The second said anchored unit is a shore structure erected on the shore or bank and forms a guided pathway with the first anchored unit. The shuttle floatation unit moves between the anchored floatation unit and the shore structure on the shore to carry passengers and goods in either direction. According to another objective of the invention, guidance and activation mechanisms are provided to allow the passengers to control the movement of the shuttle floatation unit either by manual means or motorized means. The movement of the shuttle floatation unit can be controlled by pulling the pulley cordage of the activation mechanism from any position as long as the user is accessible to the pulley cordage.
Brief Description of the Drawings
[6] The shuttle floating jetty is described hereinafter with reference to the following drawings, in which:
[7] FIG. 1 shows a schematic view of the shuttle floating jetty.
[8] FIG. 2 shows the anchorage system of shuttle floating jetty.
[9] FIG. 3 shows a schematic view of the shuttle floating jetty with a floating shore structure.
Detail Description
[10] The shuttle floating jetty comprises two anchored units, a shuttle floatation unit and control means. The first anchored unit is an anchored floatation unit 30 on the deep side of the waterway and secured to the seabed 32. The second anchored unit is a shore structure 18 secured on the shallow side of the waterway and preferably on the shore or bank 19. Between these two anchored units 30 & 18 is a shuttle floatation unit 10. The activation and guidance means include pulley system 24 and cable guides 26 linking the three units 30, 18 & 10 together.
[11] The shuttle floatation unit 10 transports passengers and goods to and fro the anchored floatation unit 30 and the shore structure 18. In effect, the shuttle floatation unit 10 moves passengers and goods between the deep side of the waterway and the shallow side of the waterway. The user pulls the cordage 22 of the pulley system 24 to control the movement of the shuttle floatation unit 10.
[12] The anchored floatation unit 30 is deployed at the deep side of the waterway such sea, lake or river where marine vessels have sufficient depth to moor. The anchored floatation unit 30 is secured to the seabed 32 by means of anchor cables 34 that have sufficient length and flexibility to accommodate waves and tides. The anchored floatation unit 30 is sufficiently large to ensure stability and safety for loading and unloading of either passengers or goods or both. A shore structure 18 is constructed on the shore 19. Cable guides 26 are used as the guidance mechanism to link the shuttle floatation unit 10 with the shore structure 18 and thus allowing the shuttle floatation unit 10 to move freely in between these two units 30 & 18. In other words, the shuttle floatation unit 10 moves to and fro between the anchored floatation unit 30 and shore structure 18, by means of pulling pulley cordage 22 of the pulley system 24 and guided by the cable guides 26. The user can control the movement of the shuttle floatation unit 10 as long as the user has access to the cordage 22 from any position.
[13] The anchored floatation unit 30 is positioned at the deep end of the sea. In order to maintain its position and stability, the anchored floatation unit 30 is secured by means of counter weight such as a concrete block or permanent anchor pegged to the seabed 32 by anchor cable 34 while allowing some small movement to accommodate the waves and tides. The anchored floatation unit 30 serves as a landing platform for ferrying services or any aquatic activities for either passengers or goods. Provisions are provided for marine vessels to moor with the anchored floatation unit 30 such as boat cleats and other appropriate means.
[14] The shore structure 18 is constructed with sufficient rigidity on the shore 19 as the other anchor point of the shuttle floating jetty system. The shore structure 18 may be constructed in various ways as long as it provides an anchored platform on the shore 19. A floatation structure with proper fixation to the shore 19 is an option as shown in Fig 3. The shore structure may also be constructed using a wooden platform with a minimum of three poles fixed securely to the shore to serves as anchor points for the guide cables 26 and pulley systems 24 accordingly.
[ 15] The pulley system 24 links all the units namely the anchored floatation unit 30, the shore unit 18 and the shuttle floatation unit 10 together. The pulley system 24 has its respectively pulleys mounted on posts 12, 14 and 16 fixed onto the three units 30, 10 and 18 respectively. The pulley posts 12, 14 and 16 are preferably of height between Im to 1.5m to facilitate the ease of pulling by a typical height person. Pulley cordage 22 that can withstand the weather elements is used. The pulley system 24 is preferred to incorporate suitable mechanical advantage to facilitate manual operation or motorized operation accordingly. For manual operation, the user can move the shuttle floatation unit 10 from any of the three units namely the anchored floatation unit 30, the shuttle floatation unit 10 and the shore unit 18 as long as the user has access to the pulley cordage 22. Provision such as a winching wheel 20 is used for manual operation.
[16] The shuttle floatation unit 10 is used to ferry passengers and goods to and fro between the anchored floatation unit 30 on the deep side of the waterway where marine vessels are moored and the shore structure 18 on the shore 19. In essence, the shuttle floatation unit 10 ferries passengers and goods from the marine vessel to the shore and vice versa. The user pulls the pulley cordage 22 to control the movement of the shuttle floatation unit 10 to move in either direction according to the need of the users.
[17] Guidance mechanisms are to be provided to the guide the shuttle floatation unit 10 to move between the two anchored units 30 & 18 in a smooth and safe manner. The preferred guidance mechanisms are cable guides 26 fixed onto both sides of the three units namely the anchored floatation unit 30, the shuttle floatation unit 10 and the shore unit 18 to enhance the stability and safety of the system.
