I. Project Overview

Our company provides long‑term export logistics services for large ship anchors to shipbuilding and ship‑repair enterprises. A ship anchor is a heavy monolithic cast‑steel special‑shaped component and a core over‑dimension spare part for marine vessels. Featuring heavy dead weight, irregular contours and no standard lifting points, it is classified as out‑of‑gauge special cargo and cannot be shipped in standard containers. With customized special‑container transport solutions, we address key pain points of irregular overweight cargo including difficult lifting, challenging securing and high corrosion risk, to support regular supply demands of overseas shipyards.

II. Key Transportation Challenges

1. High risks in lifting irregular‑shaped cargo Ship anchors have non‑uniform structures with unpredictable center‑of‑gravity offset and no standardized lifting lugs. Conventional lifting methods may cause uneven stress and unilateral swinging, which readily lead to physical impacts and paint‑coating damage.

2. Challenging corrosion protection for cast‑steel material Manufactured entirely from cast steel, ship anchors have limited corrosion resistance. The high‑salt‑fog and high‑humidity environment during ocean transportation tends to trigger surface rust and oxidation, impairing both functional performance and surface quality for marine fitting applications.

3. Difficult securing for overweight and irregular cargo Being overweight and out‑of‑gauge with unique shapes, ship anchors maintain unstable center of gravity after loading into special containers. Shifting and collision may occur under rough sea conditions. Conventional securing measures fail to meet the fastening requirements for such irregular heavy‑duty cargo.

III. Implementation Procedures

1. Customized dedicated lifting solution On‑site verification of anchor dimensions, dead weight and center‑of‑gravity position is performed in advance. Tailor‑made lifting tools are adopted to precisely lock stress‑bearing points. Standardized operations are enforced throughout hoisting, relocation and container loading to ensure smooth handling and eliminate collision damage.

2. Full‑scope anti‑corrosion treatment The existing anti‑corrosion coating across the anchor surface is inspected and reinforced, with minor blemishes repaired. High‑strength waterproof and anti‑corrosion wrapping materials are applied externally to isolate the product from moisture and salt fog, fundamentally mitigating rust risks during ocean transit.

3. Special‑container dedicated securing and stop‑limiting measures Loading position inside the special container is optimized according to the irregular structure of the anchor. Anti‑slip cushion layers are laid on the container floor. Dual securing is implemented combining multi‑point steel‑wire‑rope lashing and rigid solid‑wood blocking, effectively preventing shifting and swinging of the irregular heavy cargo.

4. Whole‑process milestone tracking & delivery Complete sets of over‑dimension‑cargo technical documents and customs‑declaration papers are compiled to ensure compliant shipment. Sailing status is continuously monitored with real‑time logistics milestone updates, ensuring on‑time and intact delivery to overseas yards.

IV. Delivery Outcome

Large‑size ship anchors of various specifications have been safely transported via ocean‑going special containers. No deformation, collision marks or rust oxidation occurred in transit. Product quality fully satisfies supporting standards for overseas shipbuilding and ship‑repair projects. Our customized logistics solution for irregular over‑weight cargo enables stable handling of regular export shipments for heavy marine spare parts, effectively safeguarding project schedules of overseas shipyards.
