UHMWPE Navigation Aids

UHMWPE Light House Presentation

Shandong Buoy&Pipe Industry Co.,Ltd is specialized in the researching and manufacturing of UHMWPE pipes and navigation aids products. Our company is the only manufacturer using UHMWPE material to produce navigation aids products in the world, and the only IALA(International Association of Light House Authorities) member of plastic buoys supplier in China. Our company have 18 national patents for UHMWPE navigation buoys and light houses. Futhermore, we are appointed to be the production base of navigation buoy and other support equipment for shipping in China 12th-Five-Year National Stratefy Plan,Shandong Penninsula Blue Economic Zone Development Program.

I. Brief Introduction

• The Light House is a special mark to guide the navigation and location of the ships, mark the

obstruction and warnings. It is made up by the pillar, platform and foundation. The platform

is used to install the signal lights to provide light and signals for the ships. The pillar is used

to support the platform.

The UHMWPE pillar has advantages of corrosion resistance, maintenance free and longer

service life, etc.

The average molecular weight for the UHMWPE material is 3.5 million to 9.2 million. It has

the superior properties of impact resistance, wear resistance, self lubrication and chemical

resistance among the plastics. Furthermore, UHMWPE material is good at low temperature

resistance. It can keep higher impact resistance at the temperature of -40℃， and could

work at -269℃.

III. UHMWPE Light House PROPERTIES

1.Maintenance free: The UHMWPE Light House can be installed fast at the working site, and it is maintenance free without frequent painting. The foundation completely finds the solution for the sea water corrosion.

2. No mechanical construction: The UHMWPE Light House has split structure, which can be adjusted according to different heights. The height for each section is 0.75m to 1.0 m, with weight of 65kg to 150kg. It is easy for transportation and handling, without construction machinery.

3. Longer service life: The service life of UHMWPE Light House could be 10 times of steel beacon under same working condition.

4. Each section will be connected by 316L stainless steel bolts, which is reliable and easy to

assemble.

5. No color fading: The Clariant pigments are used for the mateiral. With UHMWPE material’s

own color, the light bacon could reach 8 grade sun-proofs.

6. The thermal deformation of UHMWPE material is 83℃, and it could keep mechanical

properties at low temperature of -70℃, which is much more superior to common plastics.

Therefore, the UHMWPE Light House will not be effected by temperature at the worldwide sea

areas

IV. UHMWPE Light House DEPLOYMENT GALLARY

UHMWPE Light House deployment brief introduction

• The UHMWPE Light House was successfully researched in 2009, and

they had been used in all the sea areas in China. The beacons are still

working very well after the powerful typhoons every year, and the pillar

keeps bright color and good structure until now.

• The earliest UHMWPE Light Houses in Xiamen had been used more

than four years. All the typhoons, named, "Linfa", "Morak",

"Lionrock", "Morandi", "Chub", "Sarika", "Nanmadol", "Talim",

"Saola", "Haikui", "Kaitak", "Tembin", "Soulik", etc, the maximum

winds reaches to be 13 grade typoon. All the Light Houses are working

well, pls see following pictures:

UHMWPE Navigation Buoy

• UHMW-PE Navigation Buoy is kind of signal for vessel guiding, positioning,

obstacles marking and warning marking. The buoy consists of light stand, floating

body and tail pipe. The light stand is used for the signal light, which will provide light

signal for vessels, the floating body will provide sufficient buoyancy for the buoy, and

the tail pipe with ballast is to guarantee the stability of the buoy.

• The UHMW-PE navigation buoys are impact resistant, maintenance free, with

longer service life.

UHMWPE Navigation Buoy Properties

Innovative Advantages

• Minimum Maintenace Costs:

• 1. The color of the float is the material‘s own color, it will not need to paint.

Shanghai QualitySupervison and Inspection Institute tested the UHMWPE material

by aging tests according China nationla standard, there is no aging and fading,

which will minimize the costs for painting.

• 2. with strong non-adhesion, the floats and tail pipes will be not easy to adhere

water growth, minimize the costs for the cleaning.

• 3. With good collision resistance, the UHMWPE buoys are not easy to be damaged by ships, which minimize the costs for buoys repairment and replacement.

• Collison Resistance:

• 1. with good resilience and hardness, the buoy hull could absorb the collision energy and return to the original shape when impacted

• 2. with light weight, the buoy has small inertia, and it could shift qucikly to dissolve the collision strength to avoid the damaging.

• 3. with good toughness, the buoy is stretch resistant, and hard to be tear(UHMWPE break elongation is 453.7%, while steel material is 26%), which could maximumly absorb the collision energy.

• 4. there are strong steel skeleton supported, and high density waterproof polyurethane foam is filled inside the float, which will help the buoy to bounce back without distortion when impacted.

• 5. the safety guard ring for lantern is made by UHMWPE sheet, and supported by the steel frames, could absorb the collision energy and improve the protection to lantern and solar panels.

Longer Service Life:

• 1. with good chemical stability, the UHMWPE material has good corrosion resistance, and it will not decompose for decades in the sea.

• 2. Anti-aging additives are added within the UHMWPE material, it will not be aging for decades and the mechanical properties will not change.

• 3. the lantern stand is treated by phosphating, and marine grade paints will be painted, so the service life of lantern stand will be much longer.

• 4. The mooring eyes are connected with internal steel frame, so its loading capacity is largely increased.

Here is the comparison between the UHMWPE buoy and steel buoy after one year

deployment:

UHMWPE Navigation Buoy Collision Test Succeed in China

CCS(China Classification Society) inspected the quality of the UHMWPE

navigation buoy by the collision test at the Qilita Sea in Ningbo, China on

Sep 4, 2014.

• The test was organized by CCS, and Ningbo Navigation Buoy Bureau arranged its coast guard

ship No. 1648( 500 tons) to fulfill the tests by two times. During the first test, the ship speed

is 9 knots, hit from the side of the ship’s bow. There is slight deformation about 20*15 square

centimeters at the buoy surface, but it becomes to be its original shape after half an hour.

During the second test, the ship speed is 4.8 knots, hit from the front of the ship’s bow, the

UHMWPE buoy was pressed into water by the ship’s bow and floated on the water from the

ship’s stern. There is a little abrasion on the super structure and tail pipes due to the propeller

collision. The navigation buoy float, super structure, lantern and top mark are in good

condition. There is about 10*15 square centimeters area at the ship’s bow paint off, but no

damages with the ship.

•

• This collision test proofed that the UHMWPE navigation buoy has benefit of collision

resistance and meanwhile it can protect the ship from damaging
