Shipowner of ARAWANA
    Shipowner of ARAWANA

    In August 2025, our ship encountered a sudden starboard windlass failure at the anchorage of ALIAGA Port in Turkey, and it was impossible to heave the anchor and enter the port, which was an extremely urgent situation. After contacting STC MARINE ENGINEERING LIMITED, they immediately set up a WeChat communication group. The technical personnel quickly determined the cause of the failure through videos, and also specially took photos and videos of the disassembled hydraulic motor parts to visually guide the crew in disassembly and maintenance. From analyzing the problem, proposing solutions, to assisting us in completing operations such as grinding the oil distribution shaft and repairing the cross key, the whole process was professional and efficient. The windlass was successfully repaired in just over 6 hours, ensuring the smooth entry of the ship into the port for loading. Their technical team is not only experienced, but also has a response speed that far exceeds expectations. The after-sales support is extremely reassuring, and they are a long-term and trustworthy partner!

    Our Advantages

    Exceptional Product Quality

    We maintain strict quality control throughout production:
    - Pre-production: Computer-aided design and high-precision CNC machining
    - Production: Hydraulic components undergo 1.5× working pressure testing and pressure holding tests
    - Post-production: Performance testing on professional test benches with anti-corrosion treatments
    We use seals from renowned international brands (NOK, SKF, PARKER, TECNOLAN) to ensure durability, with all products backed by a 1-year warranty.

    Fast and Reliable Delivery

    Leveraging an efficient supply chain and adequate inventory, we ensure rapid delivery:
    - Stock items (like most hatch jacks and standard sheaves): shipped within 1-2 days
    - Non-stock or customized products: delivered within 5-15 days
    - Emergency orders: air freight available (3-5 days to global ports via Shanghai/Ningbo)
    This flexibility minimizes downtime, especially crucial for urgent situations like anchor windlass failures.

    Comprehensive One-Stop Service

    We provide end-to-end services covering the manufacturing, overhaul, and supply of marine hydraulic equipment. In addition to producing hydraulic cylinders, motors, and valves, we offer:
    - Laser cladding for worn components
    - On-site repairs
    - Lifelong technical guidance
    From pre-sales support (drawing approval, technical consultation) to after-sales assistance (remote troubleshooting, on-board repairs), we deliver seamless service throughout the product lifecycle, eliminating the need for customers to coordinate with multiple suppliers.

    Our History

    2024
    We upgraded our production equipment to boost efficiency and meet client demands for faster delivery. We purchased high-end equipment such as CNC deep hole boring compound machine tools, CNC hydraulic cylinder liner honing machines, and large vertical machining centers, and established a specialized production line for marine hatch cover hydraulic cylinders. This upgrade significantly shortened the delivery time of hatch cover hydraulic cylinders from 15 days to 3 days, allowing us to more effectively meet our customers' urgent delivery needs – a reflection of our focus on fast and reliable delivery capabilities.
    2016-01-01
    2016
    To further enhance the reliability of our hydraulic maintenance services, we introduced a full-digital control 160KW hydraulic test bench. Through this high-precision testing link, we strengthened the quality control of hydraulic maintenance, ensuring that every repaired component meets strict performance standards – a practice that remains a key part of our quality assurance system.
    2016-01-01
    2016
    We expanded our business scope by adding the supply and professional repair services of hydraulic motors and hydraulic pumps. This expansion allowed us to form a dual-track service capability of "products + maintenance", enabling us to provide more comprehensive support to our clients beyond just product supply, aligning with our commitment to one-stop marine hydraulic services.
