What are the differences in vehicle protection between short distance and ocean shipping

Many overseas customers are puzzled: why do some vehicles only make simple packages while others require a full set of sealed anti rust protection, even for export heavy trucks? In fact, the core reasons are completely different sea freight distances, shipping schedules, and maritime climate environments. The difference in corrosion risk and turbulence risk between short distance nearshore routes and long-distance ocean routes is significant, and the protection standards cannot be generalized. Targeted matching protection schemes are necessary to prevent new cars from rusting, getting damp, and being bumped upon arrival at the port, ensuring the quality of the delivered products.
1, The risk of corrosion varies greatly depending on the transportation time
Short distance sea transportation mainly covers Southeast Asia and neighboring countries near the ocean, with short shipping schedules and sailing times generally ranging from 3-7 days. The accumulation time of moisture and salt spray in the cabin is short, and the probability of vehicle corrosion is low. The focus of protection only needs to deal with temporary rainfall, dock dust, and slight moisture in short distance cabins.
Ocean shipping is aimed at regions such as Africa, South America, the Middle East, and Europe, with a shipping period of 30-45 days. The large temperature difference across the equator, high salt spray on the sea surface, and the temperature difference between day and night in the cabin can easily generate a large amount of condensation water. Long term high humidity and high salt environment continuously corrodes the chassis, circuits, paint surface, and bolts, making it a high-risk route for rust and moisture in new car shipping. It is necessary to upgrade the full set of reinforced protection.
2, The focus of core protection varies
Short distance offshore: focus on dust prevention, rain prevention, and slight moisture prevention
Near ocean routes do not require heavy anti-corrosion treatment, basic protection is sufficient. The whole vehicle is covered with waterproof and dustproof tarpaulin, the cab and electrical interfaces are simply sealed, and the key points of the chassis are sprayed with simple anti rust oil, with a focus on preventing dust from being piled up at the dock and rainwater splashing during transportation, meeting short-term transportation protection needs.
Long distance shipping: focus on preventing salt spray, condensation, and long-term oxidation
The highest export protection standards are implemented for ocean routes. The entire vehicle is enclosed and covered with film, and a large amount of desiccant is placed inside the cabin; Long term anti rust wax is sprayed on the chassis to cover the gaps and welding dead corners of the beams; The piston rod, brake system, and bolt components are individually sealed and protected; Waterproof wrapping of all vehicle circuit plugs to prevent circuit faults caused by condensation water infiltration.
3, Different standards for fixed protection against ship bumps
The nearshore sea surface is relatively stable, with minimal ship shaking. Vehicles only need to be fixed on the foundation and have anti-skid limits, and there are almost no displacement or collision problems.
Due to the strong winds and waves in the ocean, the ship's hull is subject to severe shaking. Vehicles must use multi-point reinforcement and binding, triangular wooden limit, and chassis tightening and fixing processes to prevent long-distance maritime vehicles from slipping, colliding, and deforming under stress, and to avoid damage to the body, tires, and pipelines.
4, Differences in dock detention protection
Short haul routes have fast turnover, short vehicle dock stay time, and less exposure to sunlight and dust accumulation in the open air. Long waiting times for ocean shipping routes, long shipping cycles, and vehicles stranded in ports require additional protection against sun, dust, and oxidation to prevent damage to the factory products.
Summary
Simply put, short distance sea transportation focuses on dust and water prevention, while ocean shipping focuses on anti-corrosion, anti condensation, reinforcement, and anti shaking. Professional export manufacturers do not package products uniformly, but customize differentiated protection plans based on route distance, shipping schedule, and sea environment. This approach neither wastes costs by excessive packaging nor simplifies protection measures to prevent cargo damage. All heavy-duty trucks exported by our factory are protected according to the route classification, ensuring that each vehicle arrives at the port intact and can be put into construction immediately upon landing.
