What is M&R for marine containers?

M&R (Maintenance & Repair) is a comprehensive set of services for the technical maintenance and repair of containers, aimed at keeping them in working condition and compliant with international standards (IICL, CW).

How much does minor marine container repair cost?

The cost depends on the defect type, region (Russia or China), and scope of work. For example, replacing seals costs significantly less than patching a hole in the corrugation. We provide an exact estimate after inspecting the container at the yard.

Can the watertightness of an old container be restored?

Yes, in 95% of cases. We replace the rubber door seals (gaskets) and seal the roof and wall seams with specialized mastics, which completely eliminates water leaks ("container rain").

What is included in a reefer PTI test?

Pre-Trip Inspection includes checking the compressor's operation, the defrost system, door tightness, the integrity of the T-bar floor, and calibrating the temperature sensors. Upon completion, an official PTI certificate is issued.

Do you perform container repairs directly in China?

Yes, we have streamlined processes and partner repair depots in all major Chinese ports (Shanghai, Shenzhen, Nansha, etc.). This allows us to prepare equipment for the voyage right at the point of departure.

How is container geometry restored?

We use specialized hydraulic tools to straighten bent corner posts and top rails. We also adjust or replace door hinges and keepers so the doors close without gaps and pass the standard gauge test.

Do you replace the flooring in a marine container?

Yes, we replace individual damaged floorboards or the entire floor covering. We use certified plywood or timber treated against pests, in accordance with IPPC convention requirements.

Do you issue a certificate after the repair?

Yes. If the repair was carried out to bring the container to IICL condition, we can organize a survey and issue the corresponding certificate or update the CSC plate (if necessary).

How long does minor repair take?

Standard operations (seal replacement, minor welding, washing) take 1 to 3 business days, depending on the yard's workload and parts availability.

Can a container be repaired at our own premises?

We perform repairs exclusively at equipped container yards (depots) in Russia and China, where there are the necessary utilities (electricity, water), tools, and conditions to comply with safety regulations.

How can I find out the repair cost before work begins?

We work on an estimate approval system. We send you photos of the defects and a detailed breakdown of labor and material costs. Repair begins only after your written approval.

Do you repair reefer refrigeration units (compressors) in-house?

We perform diagnostics and basic maintenance. For complex major compressor repairs or electronic board replacements, we involve authorized service centers (e.g., Carrier or Thermo King) at the same facilities.

What should I do if a container fails acceptance at the port due to defects?

We promptly pick up such a container to our yard, eliminate the surveyor's remarks (e.g., weld a hole or replace a seal), and return it to the port for another acceptance attempt.

Do you provide a photo report of the completed work?

Absolutely. This is our quality standard. You receive clear "before and after" photos for each type of work performed, ensuring transparency and justifying the costs.

Is there a warranty on the repair work?

Yes, we provide a warranty on all types of work performed and replaced components (e.g., for the watertightness of new seals or the quality of welds) in accordance with the contract terms.

Marine Container Repair at Facilities in Russia and China: From Restoring Watertightness to PTI Tests

Professional repair and maintenance of marine containers (M&R). Hole patching, restoration of watertightness and geometry, and PTI tests for reefers at facilities in Russia and China. Quality guaranteed.

Marine Container Repair at Facilities in Russia and China: From Restoring Watertightness to PTI Tests

A marine container is an asset constantly exposed to harsh conditions: saltwater, mechanical stress during loading, and temperature fluctuations. Natural wear and tear, dents, or damaged seals can lead to cargo rejection at the port, spoilage of goods ("container rain"), and penalties from shipping lines.

MyContainers provides comprehensive repair and maintenance (M&R — Maintenance & Repair) services for container fleets. We perform these operations at our own and partner container yards in Russia (Moscow, Vladivostok, Novorossiysk, St. Petersburg) and China (Shanghai, Shenzhen, Nansha), ensuring equipment compliance with IICL and CW standards.

1. Types of Repair Services We Provide

We specialize in prompt, high-quality minor and medium repairs that restore a container's operational characteristics without the need for decommissioning or major overhaul.

Reefer PTI Test	Refrigeration unit malfunctions, sensor errors	Compressor diagnostics, defrost system check, sensor calibration, load test (Pull-down test)	Issuance of Pre-Trip Inspection certificate, clearance for perishable transport
Comprehensive Maintenance	Dirt, corrosion, floor wear	Washing (interior/exterior), spot painting, replacing damaged floorboards, disinfection	Restoring the container to a presentable condition and sanitary standards

2. Geography of Repair Facilities

The speed of repair directly depends on the proximity of the service crew to the container's location. We minimize the logistics leg by performing work directly at container yards (depots) in key hubs:

🇷🇺 Russia: Vladivostok, Nakhodka, Novorossiysk, St. Petersburg, Moscow, Yekaterinburg. The facilities are equipped with welding equipment, compressors, and have access to electricity for reefer tests.

🇨🇳 China: Shanghai, Shenzhen, Nansha, Guangzhou, Qingdao, Tianjin. Direct coordination with Chinese repair depots allows us to carry out work quickly and at competitive local rates.

3. Why It Is Profitable to Repair Containers with MyContainers?

Transparency and control: Before starting work, we compile a damage report and agree on an estimate with you. After the repair, we provide a detailed "before and after" photo report.
Compliance with standards: All work is performed in accordance with IICL (International Institute of Container Lessors) requirements. We know which defects are critical for surveyors and which are acceptable for CW (Cargo Worthy) condition.
Time savings: You don't need to search for contractors, sign contracts with them, and control quality. We take on the entire cycle: from receiving the container at the yard to handing over the finished equipment.
Comprehensive approach: We can not only repair the container but also immediately lease it to you, sell it, or organize its delivery to your warehouse.

4. How the Repair Process Works (5 Steps)

Request and damage assessment: You submit a request. Our specialist at the yard conducts an inspection, records defects, and prepares a preliminary estimate.
Approval: We send you the estimate and photos of the defects. Work begins only after your approval.
Execution: Qualified crews carry out the repairs (welding, seal replacement, straightening) in compliance with safety regulations.
Quality control: The site supervisor checks the quality of the welds, door tightness, or conducts a PTI test for reefers.
Reporting and release: You receive the final photo report, a certificate of work performed, and, if necessary, an updated container condition certificate.
