PT Samudera Luas Paramacitra (SLP) showcased its locally developed and manufactured ship-launching rubber airbag at INAMARINE 2026, highlighting Indonesia’s growing capability in marine and shipyard technology. Through its participation in the INAMARINE Expo 2026, held from July 28–30, 2026, at the Jakarta International Expo (JIExpo), Jakarta. At the exhibition, SLP participated in the IPERINDO Pavilion (Association of Indonesian Shipbuilding and Offshore Industries).

SLP showcased one of its flagship products, the SLP Ship Launching Rubber Airbag (“SLP Rubber Airbag”). This “Made in Cirebon” Rubber Airbag attracted considerable attention from exhibition visitors, particularly shipbuilding companies and shipyards from both Indonesia and overseas.

The SLP Rubber Airbag is a high-quality rubber product designed to support ship launching and ship lifting operations. With its ability to withstand heavy loads, high flexibility, and resistance to demanding marine and outdoor operating conditions, the Rubber Airbag offers an efficient and modern solution for shipbuilding and maritime industries.

One of the key advantages of this technology is its ability to operate without extensive permanent infrastructure. Unlike conventional launching and docking facilities such as permanent slipways, rail-based systems, and graving docks, Rubber Airbags allow docking operations to be carried out with simpler and more flexible infrastructure.

“With a properly prepared and suitably sloped launch or haul-out area, a shipyard can carry out vessel launching and recovery operations without relying on a permanent dry dock.” explained Adi Limansubroto, Director of PT Samudera Luas Paramacitra.

In addition to ship launching and hauling-out, SLP Rubber Airbags can be configured for vessel relocation and certain salvage operations, subject to project-specific engineering assessment.

“The main advantage of Rubber Airbags is their flexibility. When a docking system uses rails, slipways, or graving docks, the location is fixed. With Rubber Airbags, however, the docking location becomes much more flexible. This is highly beneficial for shipyards in Indonesia,” Adi added.

To meet the requirements of various types and sizes of vessels, SLP provides Rubber Airbags in a wide range of specifications, including:

• Diameter: 75 cm, 1 meter, 1.2 meters, 1.5 meters, 1.8 meters, and up to 2 meters.
• Length: 3 meters to 20 meters.
• Number of rubber plies: 5 to 12 layers of synthetic-tire-cord reinforcement, depending on vessel requirements and load capacity.

These variations allow SLP Rubber Airbags to be configured according to operational requirements and the specific characteristics of the vessel being handled.

Behind the development of the SLP Rubber Airbag lies an extensive research and development process conducted in collaboration with BPPT (the Agency for the Assessment and Application of Technology), which was subsequently integrated into BRIN from April 2017 to March 2019. As a result, the SLP Rubber Airbag became Indonesia’s first domestically developed and manufactured ship-launching airbag which are developed and tested with reference to international standard such as ISO 14409, demonstrating SLP’s commitment to developing maritime technology and reducing Indonesia’s dependence on imported products.

“This is our effort to reduce dependence on imported products and support the use of domestically manufactured technology. We encourage shipyards across Indonesia to support and use domestically manufactured products. Today, SLP Rubber Airbags have been used by shipyards across Java, Kalimantan, Sumatra, and Papua,” said Adi.

Water gates are essential components in irrigation systems, dams, reservoirs, and flood control infrastructure, serving to regulate water flow and water levels. However, the performance of a water gate depends not only on the strength of its structure but also on the effectiveness of its sealing system in preventing leakage. This is where gate rubber seals play a crucial role.
A gate rubber seal is a rubber sealing element installed along the left, right, bottom, or top edges of the gate leaf to close the gap between the gate leaf and the frame. When the gate is closed, the seal is compressed, creating a watertight seal.
Gate rubber seals are commonly manufactured from Natural Rubber (NR), which offers excellent elasticity, and Styrene Butadiene Rubber (SBR), which provides superior abrasion resistance and durability under repeated opening and closing cycles.

Gate Rubber Seal is specifically designed to deliver reliable sealing performance under a wide range of operating conditions. Its flexible bulb profile adapts to pressure variations and surface irregularities, ensuring effective sealing while protecting gate components against wear and tear.
Its key advantages include:
• Provides a tight seal through a broader contact surface, effectively minimizing water leakage and seepage.
• Maintains elasticity even after repeated compression, ensuring long-term sealing performance.
• Compensates for installation tolerances and uneven structural surfaces without compromising sealing effectiveness.
• Absorbs vibration and impact caused by hydraulic pressure and fast-flowing water, resulting in smoother and more stable gate operation.
• Prevents direct contact between the gate leaf and the frame, reducing wear and extending the service life of both components.
• Features a practical installation system using a clamp plate, making installation, inspection, and seal replacement easier and more efficient.
• Helps maintain controlled water flow by providing consistent and reliable sealing performance.

Selecting the appropriate seal profile for the operating conditions of a water gate can significantly improve sealing performance, reduce water loss caused by leakage, and extend the service life of the entire structure.

Elastomeric bearing pads are essential components in bridge construction, serving as the interface between the superstructure and substructure. Their primary functions are to transfer vertical loads, accommodate translational movements resulting from temperature variation, creep, shrinkage, and live loads, and permit rotational movements between the superstructure and substructure.

Because of their critical role, elastomeric bearing pads must be designed, manufactured, and tested in accordance with recognized standards. In Indonesia, bridge bearing pads are commonly specified in accordance with SNI 3967:2013, while some projects may also reference international standards such as AASHTO M251 and various ASTM testing standards. Together, these standards help ensure the quality, safety, and long-term performance of bearing pads throughout the service life of a structure.

SNI 3967:2013

SNI 3967:2013 is the Indonesian national standard that specifies elastomeric bearings for bridge applications, including both plain bearings and laminated bearings. The standard covers material requirements, dimensions, tolerances, and product performance criteria.

It also defines key elastomer properties such as hardness, tensile strength, deformation characteristics, and resistance to long-term loading. For laminated bearings, the standard regulates the use of reinforcing steel plates to improve load-bearing capacity and structural stability. In addition, SNI establishes testing procedures, including compression tests, shear tests, and physical property evaluations to ensure that bearing pads meet bridge design requirements.

AASHTO M251

Published by the American Association of State Highway and Transportation Officials (AASHTO), AASHTO M251 is one of the most widely recognized international standards for elastomeric bridge bearings.

The standard provides detailed requirements for elastomer materials, hardness (durometer), rubber layer thickness, laminated steel plate specifications, and allowable deformation limits. The specification establishes material, dimensional, and fabrication requirements intended to ensure reliable performance under service conditions. As a result, AASHTO M251 is widely used in highway projects, long-span bridges, and other critical infrastructure developments.

ASTM D-Series

The ASTM D-Series focuses on testing the quality of elastomer materials used in bearing pad manufacturing. Some of the most commonly referenced standards include:

• ASTM D2240 – Measures material hardness (Shore A).
• ASTM D412 – Evaluates tensile strength and elongation at break.
• ASTM D395 – Measures compression set, which indicates the material’s ability to recover its original shape after being subjected to prolonged compression.

Additional standards commonly used include ASTM D4014 for evaluating the physical properties of bridge elastomeric bearings, ASTM D573 for accelerated aging resistance testing, and ASTM D624 for tear resistance testing. Together, these tests provide a comprehensive assessment of the quality and durability of elastomer materials.

In practice, SNI 3967:2013, AASHTO M251, and ASTM D-Series standards complement one another. SNI serves as the national product specification standard, AASHTO establishes design and performance requirements, and ASTM ensures material quality through standardized testing methods.

Bollards play an important role in maintaining vessel safety during mooring, berthing, and cargo loading or unloading operations at port facilities. In operation, bollards are subjected to large tensile forces from mooring lines, which are dynamic in nature due to waves, currents, wind, vessel movement, and tidal changes. Because they continuously withstand heavy loads, bollards must be manufactured from the right material.

Bollard materials must have strong mechanical characteristics to prevent cracking or structural failure that could cause mooring lines to detach. In addition, bollards must be resistant to seawater corrosion and capable of long-term operation.

On the other hand, improper material selection can lead to damage to port facilities, increased maintenance costs, and even operational safety risks.

There are three commonly used bollard materials: Ferro Casting (FC), Ductile Ferro Casting (FCD), and Steel Casting.

1. Ferro Casting (FC)

Ferro Casting (cast iron) is a material commonly used for conventional bollards. It is relatively economical, easy to manufacture, and has good compressive strength. However, FC tends to be more brittle against impacts and high dynamic loads, making it more prone to cracking under heavy operating conditions.

FC material is suitable for:

• small to medium-capacity docks,
• areas with relatively low vessel traffic,
• applications with stable mooring loads.

2. Ductile Ferro Casting (FCD)

FCD, or ductile iron, is an advanced form of cast iron with a spheroidal graphite structure. This structure provides significantly better mechanical properties compared to FC.

The advantages of FCD include:

• higher tensile strength,
• better impact resistance,
• improved flexibility,
• greater crack resistance,
• higher fatigue resistance under repetitive loading.

Due to these characteristics, FCD is widely used in:

• commercial ports,
• bulk terminals,
• container ports,
• areas with high berthing frequency.

In many modern projects, FCD has become a popular choice because it offers an excellent balance of strength, durability, and cost efficiency.

3. Steel Casting

Steel Casting offers the highest performance among the three materials. It provides high tensile strength, excellent impact resistance, and superior durability under extreme loads.

Steel Casting is highly suitable for:

• heavy-duty ports,
• oil and gas terminals,
• LNG terminals,
• offshore facilities,
• large vessel berths.

Although it has a higher production cost, Steel Casting delivers excellent safety performance and long service life for heavy operational applications.

Bollards are vital components in ports, serving as mooring points to withstand the pulling forces of mooring lines during berthing, cargo handling, and departure operations. The reliability of bollards plays an important role in maintaining vessel stability while docked, especially when exposed to waves, currents, tides, and changing weather conditions. Since bollards continuously endure heavy loads, selecting the right bollard is essential for ensuring vessel safety, protecting quay structures from excessive stress, and supporting smooth, safe, and efficient port operations.

Today, several types of bollards are commonly available on the market to suit different operational requirements, including Bit Bollard, Curve Bollard, CVS Bollard, and Staghorn Bollard. Each type has its own characteristics, capacity, and functions designed to match vessel types, quay conditions, and port operational needs.

• Bit Bollard

Bit Bollards are simple and economical twin-post bollards widely used in conventional ports to withstand medium to high mooring loads. This type is suitable for general ports, multipurpose terminals, and vessels such as cargo ships, small-to-medium tankers, passenger ships, and tugboats using conventional mooring systems.

• Curve Bollard

Curve Bollards feature a curved design that helps distribute loads more evenly, reduces rope abrasion, and provides better flexibility for various mooring angles. These bollards are suitable for container terminals, bulk terminals, and modern ports with intensive operations, serving vessels such as container ships, bulk carriers, Ro-Ro vessels, and large tankers.

• CVS Bollard

CVS Bollards are designed for extremely high loads and are capable of handling mooring forces from multiple directions, making them ideal for large modern ports. This type is commonly used in deep sea ports, LNG terminals, and oil terminals, accommodating large vessels such as VLCCs, LNG carriers, mega container ships, and cape-size bulk carriers.

• Staghorn Bollard

Staghorn Bollards have a shape resembling deer antlers, allowing multiple mooring lines to be used simultaneously with stable multi-directional load distribution. These bollards are suitable for tanker terminals, offshore jetties, and energy ports handling large vessels such as oil tankers, LNG carriers, FPSO support vessels, and ultra-large container ships.

The selection of bollards should be adjusted according to vessel size, operational intensity, quay layout, and safety requirements.

Rubber bumpers are an important part of warehouse safety and protection. During loading and unloading, forklifts, trucks, and other vehicles often operate in tight spaces, where minor collisions with walls, doors, columns, and corners are difficult to avoid. Rubber bumpers help absorb these impacts and reduce damage to both property and equipment.

A rubber bumper is a protective component made from rubber and installed in areas that are likely to be hit or scraped. Because rubber is elastic, it can absorb impact and reduce the force of collisions. This makes rubber bumpers a practical solution for improving safety in busy work areas.

Rubber bumpers are widely used in logistics warehouses, distribution centers, factories, and loading docks. They are commonly installed on walls, columns, corners, and areas near forklift routes or dock doors. These products are especially useful in places with frequent vehicle movement.

There are several types of rubber bumpers, each suited to different needs. Rectangular or square bumpers are often used on wide wall surfaces or parking areas. D-shaped bumpers are popular because they absorb impact well and are easy to install, making them suitable for walls and loading zones. Cylindrical bumpers are useful in areas with movement from different directions, while corner guards protect corners and columns from repeated contact.

Rubber strips or flat bumpers are also used as additional wall protection. They are ideal for areas exposed to frequent rubbing or light impacts over time.

Proper installation is essential for good performance. The mounting surface should be clean, level, and strong enough to hold the bumper securely. Bumpers should be placed in high-risk areas such as forklift paths and loading zones. They are usually fixed with bolts and anchors so they stay firmly in place during daily operations.

With the right type and proper installation, rubber bumpers can improve workplace safety, protect warehouse infrastructure, and reduce repair costs. Choosing the correct product is an important step toward creating a safer and more efficient warehouse.

PT Samudera Luas Paramacitra produces high-quality rubber bumpers in various types to fulfil your requirements. For more information or to place an order, please visit our website at www.niri-rubber.com or contact our customer care at (+62) 823 2018 9998 or email: admin@niri-rubber.com.

Port operations reach one of their most critical moments when a vessel docks. During this phase, a vessel generates impact forces when it comes into contact with the dock. Without proper protection, this impact can damage both the dock structure and the vessel’s hull. This is why rubber bumpers play an important role.

Rubber bumpers are protective devices made of rubber and installed along the dock face to absorb impacts between vessels and port structures. Compared to heavy-duty fender systems, rubber bumpers provide lighter, supplementary protection.

Rubber bumpers are generally used in ports that require light to medium impact protection. Suitable locations include docks for small to medium vessels, jetties, fishing ports, and terminals with lower docking frequency. They are also often installed in additional areas of large ports, such as secondary sides or dock corners, as a complement to the main fender system.

Rubber bumpers are available in various shapes and sizes depending on operational requirements. The most commonly used type is the D-shape bumper, which is easy to install and suitable for small to medium docks. For areas that need wider protection, rectangular or square bumpers are used. Cylindrical bumpers offer greater flexibility and can accommodate vessel movement. At dock corners that are prone to impact, corner bumpers are installed to provide special protection.

Proper installation of rubber bumpers is critical to ensure optimal performance. The dock surface must be properly prepared before installation. Bumpers should be installed at areas that frequently come into contact with vessels, including along the berthing line and corner areas. They are installed using bolts and corrosion-resistant anchors to withstand harsh marine environments.

With proper installation, rubber bumpers can improve operational safety and extend the lifespan of both the dock structure and vessels. Therefore, choosing the right type and installation method is an important investment to support safe and efficient port operations.

In modern construction projects—especially in the building of bridges and various reinforced concrete structures—there is an important component that is often unseen but plays a very crucial role: the elastomeric bearing pad.

An elastomeric bearing pad acts as a flexible support placed between two structural elements, typically between bridge girders and their supporting structures. Its main function is to transfer loads from the upper structure to the substructure while allowing controlled movement within the structure.

Elastomeric bearing pads are usually made from natural rubber or synthetic rubber. In many cases, the elastomer is reinforced with thin steel plates arranged in layers. This reinforcement improves the bearing pad’s compressive strength and helps maintain its shape under heavy loads.

Because elastomer is naturally flexible, the bearing pad can deform under load and return to its original shape when the load is reduced. This flexibility enables the structure to safely accommodate horizontal movements, small rotations, and thermal expansion caused by temperature changes.

Types of Elastomeric Bearing Pads

Different types of elastomeric bearing pads are used depending on the structural design and load requirements.

• Plain Elastomeric Bearing Pad. Plain elastomeric bearing pads are the most basic type. They do not contain internal steel reinforcement and are typically used in structures with lighter loads or simpler movement requirements.
• Laminated Elastomeric Bearing Pad. Laminated bearing pads consist of several layers of elastomer bonded with thin steel plates inside. These steel plates increase compressive strength and help control deformation. Because of their strength and stability, laminated elastomeric bearing pads are widely used in bridge construction, flyovers, and large concrete structures.
• Specialized Elastomer Bearing Systems. In some projects, elastomer is used as part of more advanced bearing systems such as pot bearings or seismic bearings. These systems are designed to handle higher loads and larger structural movements, including those caused by seismic activity.

Key Factors in Selecting Elastomeric Bearing Pads

Selecting the right elastomeric bearing pad is an important step in ensuring the long-term performance of a structure. Since every project has different requirements, several factors should be considered.

• Load Capacity. The bearing pad must be able to support the expected structural loads. These include dead loads, live loads such as vehicles, and other operational loads that the structure may experience during its service life.
• Dimensions and Thickness. The size of the bearing pad should match the structural support area. The thickness of the elastomer layers also plays an important role in determining how much movement or rotation the pad can accommodate.
• Elastomer Material Quality. High-quality elastomer materials ensure durability and reliable performance over time. Important characteristics include: shore hardness, resistance to ozone and weather exposure, and long-term material stability.
• Compliance with Technical Standards. Elastomeric bearing pads should comply with recognized industry standards such as ASTM or the Indonesian National Standard (SNI). These standards ensure the product has been properly tested and meets engineering requirements.
• Environmental Conditions. The project environment can also affect bearing pad performance. For example, coastal structures require materials resistant to corrosion and salt exposure. Meanwhile projects in extreme climates require elastomers that remain stable under significant temperature variations.
