The main aim of installing marine rubber fender is to protect both the vessel and the dock from major failure during the berthing period. External forces, such as abrasion or other natural factors can possibly occur during the berthing process. Therefore, marine rubber fenders are made to solve this problem, and therefore, more money can be saved due to less vessel or dock fixing.

Rubber fenders are designed to absorb the energy that a vessel transfers to a berthing structure, hence the term energy absorption, so that the amount of energy received by the dock is much less compared to when fenders are absent. The force that is bounced back and relieved by the dock through the fender is called reaction force. A good quality marine fender can be determined by measuring the energy absorption and reaction force. A good quality marine fender has a high energy absorption and the low reaction force, hence the reduced impact yielded from the vessel to the dock, as well as the minimized impact bounced back from the dock to vessel.

There are a lot of fender types that can be used on the port, for instance: cylindrical fender, V-type, A-type, M-type, super cell, and super cone fender. Tugboat fenders, however, are installed on tugboats to protect vessels from major failure in the incidence of a crash. In order to achieve the best result, there are several factors that to consider in choosing the right type of marine rubber fender, namely the dimension of berthing vessels, the type of the port, situation around the port and the existence tugboat to guide the vessel while berthing.

1. Vessel dimensions

Vessel dimensions, in terms of type and dead weight tonnage, become significant factors in choosing not only the right fender type, but also the size of the fender. The larger the vessel, the larger the required fenders will be. Usually, fenders which are equipped by frontal frames are chosen as they have large contact area. From the economical perspective, V-type fender can be one of the options. However, to yield the maximum result, super cell and super cone fender are selected. For the ports that are used for the small to medium vessel, the type A, V, M, LMD or cylindrical are chosen to protect the port wall.

2. Type of the port

Another significant factor that can influence in choosing the right type of fender is the type of the port. Based on the location and position of the port, there are several port structures that are usually used including dolphin, monopile, jetty and quay wall. In the dolphin terminal, the terminal consists of poles that are used for vessels to berth. Rubber fender that is usually used in this terminal is super cell fender. However, jetty terminal, which is also known as floating terminal, does not need a really tough construction as it floats. This terminal is used for passenger ships. Unlike other kinds of ports, terminals with quay wall consists of concrete structure which parallels the beach. Large vessels cannot berth on this terminal due to the shallow waters in which the terminals are usually located.

3. Marine environment

The marine environment, such as high and low tides of the seawater, the power of wind which influences the waves, is another factor that needs to be considered in choosing the right fender type and dimension. If there is a big difference between the high and low tides, elongated fenders must be chosen, especially when the port is used by diversely sized vessels. If a small vessel needs to berth during the low tide, it can still berth to this port. Therefore, it is recommended to have the fenders installed in vertical position. On the other hand, when the sea is windy and wavy, the water also gets rough. This causes vessels to bump into the port wall. Elongated V type fender, super cell or super cone fender equipped by frontal frames can be used for this type of port.

4. The availability of guidance during berthing process

The availability of tugboats during the berthing process is very important in order to avoid vessels from crashing into the port wall. This is because the speed of the vessel and the berthing angle can be adjusted as the vessel moves closer to the port.

Warehouse storage shelves are the basic storage equipment of the cargo transfer station, in warehousing management has an important role, to properly preserve the integrity of the goods. Storage shelves set up seven principles of custody, the goods can be properly kept:

1, for the channel for custody. In order to facilitate the goods out of storage, easy to move in the warehouse, the basic conditions for the goods for the channel custody.

2, as far as possible to the height of the code, improve storage efficiency. Effective use of the volume of the library should be put to the height of the code, in order to prevent damage, to ensure safety, should be used as much as possible scaffolding and other storage equipment.

3, according to the selected frequency of the location of the library. Goods that are shipped and purchased in high frequency should be placed near the entrance, easy to work; the poorly placed items are located far from the entrances and exits; seasonal items are selected according to their seasonal characteristics.

4, the same species in the same place custody. In order to improve the efficiency and efficiency of the operation, the same item or the like should be kept in the same place, and the familiarity of the employee with the place of placing the item in the store has a direct impact on the time of entry and exit, placing the similar item in the neighboring place and improving the efficiency an important method.

5, according to the weight of goods arranged custody position. When placing a place, heavy items are placed underneath, and light items are placed on top of the shelves. Need to manually carry the large items are based on the height of the waist. Sichuan warehouse shelves said to improve efficiency, to ensure safety is an important principle.

6, according to the shape of the arrangements for storage methods. It is also important to keep the goods in accordance with the shape of the items, such as the standard goods should be placed on the tray or shelf custody.

7, according to the principle of first-in first-out. Preservation of an important one is for perishable, easy to break, easy to corrupt items; for the function of easy to degenerate, aging items, as far as possible according to the principle of ancestors first to speed up the turnover. Because the diversification of goods, personalization, the principle of short life is very important.

YSmarines has introduced the marine mooring chock which is a mooring system that is designed to support safe and reliable moorings of all types and purposes through its patented low friction technology.

The transition from steel wire rope to fiber rope is widespread across industry. Fiber rope has a good strength to weight ratio and ease of handling, resulting in much lower risk of injury.

Although advantageous, a major weakness of fiber rope is poor resistance to external abuse and abrasion through everyday operations and poor surface contact. Abrasion continues to be one of the most common root causes of rope failure and reduction in its residual strength.

It is impossible for synthetic rope to perform to its maximum capabilities when used with poorly maintained deck equipment, often rusted or with a rough surface finish. Rope manufacturers recommend surfaces are correctly prepared, maintained and routinely inspected before and after rope installation. A 300-microinch (7.62-microns) finish is recommended for all deck hardware which comes into contact with the rope, in addition to the avoidance of chocks heavily scored from previous wire rope use.

The YSmarines marine mooring chock is said to provide vessels with the ability to be moored with greater safety, performance, and efficiency.

The marine mooring technology is said to provide vessels with the ability to be moored with greater safety, performance and efficiency, offering multiple benefits. The marine mooring chock is versatile and capable of being fitted to brand new vessels and retro fitted to existing chocks and panama fairleads with no hot works or dry docking required.

Increased safety is a feature of the marine mooring chock which reduces rope wear and abrasion, reducing the risk of breaking or failure. There is also no need for crew members to be near mooring lines under tension, as minimal (if any) chafe protection is required following installation of the new system.

The marine mooring chock’s smooth surface and finish and its material characteristics provides better equalization of mooring loads, especially when in high swell. The self-lubricating, low friction marine mooring chock material requires little or no maintenance and no painting, coating or external protection. Corrosion resistant materials technology is featured on the new system, providing protection against the arduous environments faced in the global maritime industry.

Custom manufactured from initial chemistry to end product, the marine mooring chock is available for use on all chock and vessel sizes. Developed to optimize and enhance vessel moorings, much of the advantages derive from the unique materials technology developed through over 20 years of field experience in design, testing and material selection with fiber ropes.

The featured materials technology in YSmarines marine mooring chocks allows for the accommodation of HMPE fiber rope with a lower risk of abrasion and wear when in contact with the Panama chock. The marine mooring chock is also suitable for polyester/polypropylene, polyester and nylon ropes, as required for FLNG, FSRU, and STS where a specific synthetic pennant may pass through the fairlead. In all cases, due care and attention are required in relation to the loads involved, chock designs, and rope sizes.

Web guide control refers to the technical operation for the coil materials and must always keep the edge of the coils neat and consistent during the spraying, printing, punching, laminating, slitting, or other coil winding processes. Once the edges of the coils are not aligned, it will cause errors in subsequent steps, resulting in material waste. Therefore, when processing coils, it is necessary to do the correct deviations in time for the offset coils. The whole process is called web guiding. The equipment, which is used for the whole process, constitutes a set of web guide system. A typical system includes a controller, a sensor, a guide mechanism and a driver.
The importance of the web guiding system
The flexo printing machine often adopts an automatic web guide system to ensure the stable horizontal position of the printing material before entering the printing unit. It can detect the deviation of a certain horizontal edge position of the printing material and correct it in time, with an accuracy of ±0.5 mm. Generally, for opaque materials, such as paper and aluminum foil, photoelectric sensors are often used, for transparent materials, such as films, ultrasonic sensors are used. Once the printing material enters the printing area and die-cutting rewinding area, the stability of its horizontal edge position is guaranteed by the installation accuracy of the own processing machine and the parallelism between the rollers
The working principle of the web guiding system
The web guide control system is a closed-loop controller. First, the sensor detects the edge or line of the coil, and the system automatically reads the deviation of the actual position and setting the position of the coil and converts the offset into an electrical signal. They send the signal to the controller. After that the signal is calibrated by the controller, it is outputted to the linear driver. The linear driver drives the deviation correction according to the magnitude of the signal. Then the guide mechanism adjusts the coil to the set position. The drive signal of the current drive is only proportional to the deviation of the coil, which makes it possible to provide precise control for various coils.
Applications of the web guiding system
The web guide system covers a wide range of applications and is essential in various industries such as packaging, printing, labels, building materials, paper pulp, non-woven fabrics, and corrugated paper processing.

A marine searchlight is one of the handiest marine accessories to have aboard. It can help you find a navigation aid or landmark in the dark. A searchlight can also help you find things dropped in the water — if the thing floats, or the water is shallow and clear. It can also be a safety aid, used to signal for help or warn other boats of a hazard in the water. Here’s what to look for in a marine searchlight, whether for your existing boat or as an ­option aboard a boat you are buying.

Installing a searchlight in a Boat

The particulars of the installation have a large impact on a permanently installed searchlight. For instance, a light mounted on a hardtop is convenient to install and may even allow the use of a light that can be aimed manually. However, a light beam shooting over the white bow of a boat often creates a bloom of hazy light that impedes the skipper’s ability to see. If you are set on a top-mounted light, temporarily wire the light and have a helper hold it on your top while the boat is stationary at night so you can check whether this will be a problem for you. Mounting the light forward is preferable. Just be careful about searchlight rail mounts.

Many boat rails vibrate while the boat is underway. This vibration might not seem excessive for a rail, and mostly, it isn’t. But we have observed numerous boats aboard which a small vibration in the rail resulted in a huge vibration to the light’s beam, making it difficult to aim and keep on a target. For this reason, we suggest you favor a light mounted directly to the deck.

Hand-Held searchlights for Boats

Some hand-held searchlights are wired. These connect to a cigarette-lighter receptacle. If you choose this type, consider buying a quality receptacle that locks the male plug from the light. You’ll have to cut off the plug that came with the light and splice in the new locking plug, a simple DIY task. A locking plug and receptacle prevents the light’s cord from pulling out inadvertently in use — a thing that can happen at the worst moment. Also, consider installing auxiliary receptacles at other places from which you might use the light. These include at the bow, on the flying bridge, and in the engine compartment.

Other hand-held searchlights are battery-operated. These provide the freedom to move around the boat without the restrictions of a cord. Of course, unlike wired lights, which have power as long as your boat’s batteries are charged or the engine is running, a hand-held light’s batteries tend to go dead at exactly the same time a wired light’s cord tends to get pulled out of its nonlocking receptacle. Charging vigilance is required for the boater who owns a battery-operated searchlight.

With either type, make sure you select a hand-held searchlight that is heavily armored with rubber or plastic because, as sure as the tide, you will drop it. I also like lights with a brow or rim that extends beyond the lens. This not only adds shock protection but also cuts down glare and helps preserve night vision. Pick the best searchlight for your boat. A marine boat searchlight is vital for boating at night.

Coil materials refer to long-sized continuous materials such as paper, film, sheet, non-woven fabric, metal foil, silk, thread, etc. In the process of uncoiling, technological processing, winding, etc, deviation of the coil materials may occur, due to the deviation of the coil itself or the processing machine. The web guiding control system provides a solution to reduce the occurrence of such situations. The system always tracks the position of the coil material during the production and makes corrections in real-time. It can ensure and improve the quality and efficiency of production.

Working principle of web guiding

The web guiding is to guide the sensor to emit infrared or ultrasonic to monitor the operation of the coil material and send a signal to the controller. After that the controller finds that the web has a positional deviation, according to the preset command by the controller, the controller controls the drive system to swing to correct the web position.

The web guide system uses brushless DC servo motor drive, precision ball screw driv with, compact structure, good mechanical rigidity, low inertia, suitable for high-speed and high-precision web guiding.

The system is composed of a controller, a sensor, an electric driver, and a correction guide mechanism. The sensor detects the edge position of the coil material and reads the deviation between the actual position and the set position, converting the deviation into a voltage signal proportional to it. Then sends this signal to the controller. After the signal is amplified and calibrated by the controller, the signal is output to the electric driver, and the electric driver drives the guide mechanism to perform correction actions according to the magnitude of the input signal to guide the coil material to the preset position.
