Anchor Chain Product Tech News

A customer needed 4 pcs of 60kg stainless steel AC-14 anchors. Most suppliers said no. We said yes – and delivered 30 days faster, 30% lower cost. Then a Chile salmon client wanted a custom G80 mooring ring. We re-engineered it. Cost down 40%. Strength up 1.3x. This is how we work. Read on.

Both the Tonsberg Mooring Link and the Mandal Fairlead Shackle are specialized mooring connectors used to join steel wire ropes with fiber rope forerunners, allowing the combined mooring line to pass smoothly through a fairlead. While they serve the same fundamental purpose, they have significant differences in structural design and application scenarios, and they are NOT interchangeable.

In ship towing operations, the towing chain is the core component connecting the tugboat and the towed vessel, undertaking the crucial functions of transmitting towing force and maintaining course stability. This article will systematically introduce the technical characteristics of ship towing chains from aspects such as structural composition, core function, and technical parameters.

​In Single Point Mooring (SPM) operations, a million-dollar synthetic fiber mainline can be instantly rendered unusable due to friction from the hull's edge. The chafe chain, located at the end of the mooring line, is the first line of defense protecting this "lifeline at sea." A chafe chain (also called a friction chain) is a short steel chain assembly installed at the end of a synthetic fiber mooring line, passing through the ship's guide wires and connecting to the hull structure. Chafe chains are designed for dynamic friction protection during SPM operations and are not suitable for long-term static mooring.

A Mandal Fairlead Shackle is a specialized marine and offshore connector engineered to optimize mooring and towing operations by enabling seamless integration of steel wire ropes and synthetic fiber ropes under extreme loads.

A Kenter Shackle is a detachable, bow-shaped chain link consisting of two interlocking half-rings, a crossbar, and a tapered pin. It is commonly used to connect two sections of anchor chain or to connect an anchor chain to the anchor body. Unlike ordinary chain links, Kenter Shackles can be quickly assembled and disassembled on-site, making it easier to change, replace, or repair anchor chain lengths.

In shipbuilding and marine engineering, anchor chains are core components connecting ships to the seabed and securing offshore facilities. The 12.5mm Stud Link Anchor Chain, with its compact size, high strength, and flexible applications, has become standard equipment for small vessels and specialized equipment. This article analyzes its core value from three aspects: specification positioning, application scenarios, and material manufacturing processes.

Amidst the raging winds and waves on the sea, 10,000-ton giant ships remain as steady as a rock. The anchor chain, serving as the "steel backbone" of ship safety, is of utmost importance in terms of specifications, craftsmanship, and connection methods. This article will delve into how anchor chains safeguard ship safety from the perspectives of engineering standards, mechanical principles, deep-sea challenges, and innovation directions.

Anchor Chain Safety Alert: How to Protect Ship Safety When the "Lifeline" Exceeds Limit Wear? —Analysis of the Critical Lines of Defense for Global Ship Safety Anchor chains are the "lifeline" of a ship, but when they rust or exceed limits due to wear, they can cause loss of control, damage to submarine facilities, and even casualties. In April 2025, a Chinese cargo ship (1,422 gross tons) was urgently grounded by the China Maritime Safety Administration due to anchor chain diameter wear exceeding 28%. This case sounded a safety alarm for the industry. This article combines the "Technical Code for Mandatory Surveys of International Seagoing Vessels" with actual engineering data to provide global procurement decision-makers with an authoritative guide to anchor chain replacement.
