Global Shipbuilding Boom: The Hidden Trap in Anchor Chain Procurement

The global shipbuilding market is experiencing a structural surge. Clarksons data shows new vessel orders are booked through 2031. This boom isn't limited to Chinese shipyards—South Korea and Japan are also seeing a strong wave of returning orders.

In this market, lead times can usually be managed with early planning. But the real risk that trips up entire projects often lies not in the main chain itself, but in the details.

1. Where Are the Orders Concentrated?

Over the past few years, the main driver was ultra-large container ships. Recently, the order structure has clearly rotated:

Oil Tankers and Bulk Carriers Take Over: Global VLCC and Capesize bulk carrier ordering has hit multi-year highs.

Mid-Sized Container Ships Surge: Orders for feeder ships under 8,000 TEU have increased significantly.

Japan and South Korea Push High-End Vessels: South Korea dominates LNG/LPG carriers, while Japan focuses on alternative fuel ship types.

Green Fuel Becomes Standard: The share of LNG, methanol, and ammonia dual-fuel vessels has risen sharply.

This differentiation in vessel types directly leads to completely different requirements across countries for chain grades (U2/U3), specifications (mostly small to medium diameters), and classification society certifications (NK, KR, ABS, etc.).

2. A Real Case: The Chain Arrived, But the Ship Couldn't Be Fitted

In this booming market, as long as the design is fixed and the order is placed early, chain lead times are generally controllable.

However, in practice, we frequently encounter a highly overlooked trap: The chain quantity is sufficient, but the matching accessories are not.

We worked with a customer who rushed to place an anchor chain order to secure factory capacity. The chain was produced and delivered on schedule. But when it came to installation and survey, the customer suddenly realized: Kenter shackles, swivels, and end shackles were in short supply.

This may seem like a small oversight, but it caused significant trouble in delivery:

Slow Re-order Lead Time: With factories at full capacity, re-ordering accessories requires joining the back of the production queue.

Difficult Certificate Traceability: Supplementary accessories often have different heat numbers and class society certificate numbers. Plus, the small quantity makes individual testing very expensive.

Increased Freight Costs: A separate shipment is required, adding significantly to logistics costs.

3. Why Is "Not Buying Enough Accessories" So Common?

A complete marine anchor chain system is not just a simple chain. It includes:

Anchor chain + Kenter Shackle + End Shackle + Swivel + Enlarged Link, etc.

Many buyers, when requesting a quote, only provide the main chain drawing and parameters—focusing on size, material, and class society requirements—while easily overlooking:

1.Number of Connection Points: Kenter shackles are needed between chain sections, and end shackles are needed between the chain and the anchor.

2.Spare Parts Allowance: Shipowners typically require spare parts on board. If not calculated in advance, re-ordering later is very passive.

3.Independent Inspection Requirements: Under class society rules, accessories and chains are inspected and certified separately. Missing one accessory means the system's certificate is incomplete.

4. How SMEOCEAN Helps: Getting Your List Right

In a market where factories are at full capacity, competing on price alone is meaningless. The real risks hide in details like "missing accessories."

Backed by the manufacturing capacity of our group's own factories, SMEOCEAN doesn't make empty promises. What we do is use our industry expertise to verify your entire system checklist before the order is placed:

Systematic Verification: We not only confirm the chain specifications (like U2/U3 stud link chain) but also calculate the required quantities of Kenter shackles, swivels, and end shackles, ensuring a complete set.

Certificate Batch Alignment: We assist you in confirming the material, heat numbers, and class society certificate requirements for both the chain and accessories, ensuring a smooth survey.

One-Stop Supply: From chain to accessories, one order, one unified lead time, eliminating the hassle of multi-source communication.

When shipbuilding orders are booming, don't let a small set of accessories hold up the entire vessel's delivery.

If you are calculating anchor chain and accessory procurement for your project, contact us. We will help you verify the list and avoid unnecessary rework and delays.
