Dar es Salaam Port is a core hub port in East Africa, undertaking container and bulk cargo transshipment for multiple countries including Tanzania, Zambia, Malawi, Rwanda, etc. The container yard, freight channel, gate auxiliary road, and peripheral logistics main road in the port area face the Indian Ocean sea breeze all year round, with high concentration of chloride ions in the air. Combined with strong ultraviolet radiation in the equatorial region, ordinary street lights are prone to rusting, aging of the shell, and sealing failure.

Freight trucks in the port area travel day and night without interruption, and night lighting is a necessary requirement for safe operation of the port. However, the cost of laying municipal power lines is high, and excavation can interfere with container operations. LEADRAY has customized a salt spray resistant solar street light solution for the highly corrosive coastal environment of port C5-M, which is wiring free and has a long lifespan. It specifically solves the corrosion pain points of logistics road lighting in coastal ports and provides stable off grid lighting options for local EPC contractors and port management.

Port logistics roads and ordinary municipal roads are completely different working conditions. Near the coastline, continuous sea salt spray adheres to the surfaces of lamps, brackets, bolts, and lamp posts. Chloride ions will continue to corrode the metal, and ordinary galvanized parts will show rust spots and cracks after 1-2 years. Continuous exposure to strong ultraviolet radiation in the equatorial zone causes the conventional spray coating to quickly pulverize and fade, and the plastic parts to become brittle. This accelerates the aging of photovoltaic panel backboards, leading to a gradual decline in power generation efficiency.

The traffic in the port area is mainly composed of heavy-duty container trucks and trailers, which experience high vibrations and accelerate the loosening of fasteners and the expansion of sealing gaps. Salt spray is more likely to penetrate into the interior of the lamp body, causing damage to the drive and battery due to short circuits. Many port projects have limited manpower for operation and maintenance. Once the lighting fixtures are frequently damaged, the cost of repair and replacement is high, and it can also cause blind spots for nighttime driving, leading to cargo safety accidents.

The municipal power plan still has obvious shortcomings in the port area: the ground pipelines in the port are complex, and excavation and wiring can easily damage the existing water supply and drainage, communication, and fire protection pipelines; The construction period is long, and power outages are required to coordinate with the construction, which affects the efficiency of loading and unloading at the dock. The power grid itself fluctuates greatly, with unstable voltage during peak hours and frequent flickering and burning of municipal lighting fixtures. Many port projects also hope to increase security monitoring along logistics channels and walls, reducing the investment in individual poles.

Conventional inland solar street lights are difficult to meet standards here, and a complete set of marine grade anti-corrosion solutions must be adopted, which is also the design starting point of the LEADRAY port special model.

We recommend power levels based on the width of port roads and traffic types, taking into account illumination, range, and budget:
80-100W: internal passages of the yard, auxiliary roads at the gate, and small roads for container partitioning, with a road width of 5-7 meters, mainly for low-speed passage of trailers, and recommended lamp posts of 6-7 meters. The light is uniform, without strong glare, making it convenient for drivers to reverse and operate the stacker crane.

120-150W: The main logistics road and main entrance and exit road in the port area are used for two-way large vehicle traffic, with a road width of 7-10 meters and lamp posts of 7-9 meters. The illumination is higher and the distance of illumination is longer, meeting the safety requirements for high-speed passage of container trucks.

All port styles come in two versions: integrated and split. Split type is more suitable for port projects: independent bracket installation of photovoltaic panels, lifted away from ground salt spray, convenient for regular flushing of sea salt dust; The battery compartment is independently sealed and insulated, separated from the light source compartment, reducing heat conduction and extending battery life. The integrated style has a simple appearance and is suitable for landscape lighting points around gates and office buildings.
Customers can choose the lighting and monitoring two in one style according to their needs, which can achieve both lighting and video security at the same lamp post location, reducing the amount of port civil engineering pole construction.

The Tanzania port project requires a PVoC customs clearance certificate, a complete set of test reports, and salt spray test data. LEADRAY, as the source factory, can provide them in full and cooperate with customers to complete pre shipment inspection and smooth customs clearance.

After receiving the port drawings, road layout, and pole height requirements, the engineer will provide a free lighting plan, calculate the power, photovoltaic panel, and battery configuration, and avoid waste caused by insufficient or excessive configuration. Whether it is the partial lighting of the yard or the renovation of the entire inbound and outbound logistics avenue, production can be scheduled and delivered in batches according to project milestones.

We support customized color temperature, dimming logic, remote monitoring module, and logo printing. Solar street lights do not require excavation of cable trenches and can be fixed with poles. They are very friendly to construction in container intensive port areas and will not interfere with normal loading and unloading operations at the dock. After the completion of the project, there will be almost zero electricity bills, and the long-term operation and maintenance costs will be low, which is in line with the development direction of green infrastructure and cost reduction and efficiency improvement in East African ports.

We can also provide matching anti-corrosion lamp posts and grounding accessories simultaneously, packaged and delivered as a whole to reduce the trouble of multiple suppliers for engineering companies.
