Anchor Chain News

This is the second article in our Marine Delta Plate series. In the first article, "5 Questions to Confirm Before Ordering Marine Delta Plate," we covered the key parameters to confirm before placing an order — including the two manufacturing options: forged and plate-cut. In this article, we go deeper: What exactly is the difference between these two methods? If you've already determined the SWL and class society requirements but are still unsure which process or material to choose, this guide will help you decide.

A Marine Delta Plate (also called Triangle Plate) is a critical connecting component in towing and mooring systems, linking the main towline to the bridle chains. If the specifications aren't confirmed before ordering, you might end up with parts that don't fit or lack the required strength — and the rework cost can far exceed the price of the plate itself.

SMEOCEAN supplies aquaculture mooring anchors and complete anchoring systems to fish farms across Europe and South America. Our manufacturing facilities have been producing mooring equipment for the aquaculture industry for over 20 years. The following guide is based on real project experience and customer feedback from salmon farms in Norway, Chile, and beyond.” We have previously covered anchor chain selection and mooring failure risks. Now we address a more specific question: which anchor type should you choose for your fish farm mooring system? Anchor selection comes down to three factors: seabed conditions, environmental loads, and redundancy requirements.

The answer comes down to one fundamental issue: the D-type joining shackle cannot pass through the windlass gypsy wheel.

If you work with anchor chains, you know that every component must be precise. End shackles (ES) and joining shackles (JS) are two of the most easily confused components. They look similar but serve completely different purposes and are not interchangeable.

"The shipowner doesn't require classification society certification for this batch. Manufacturer A offers a very low price, while Manufacturer B is more expensive but holds all nine major certifications. How should I choose?" This is the single most common question we hear from procurement professionals. Our answer is straightforward: > If you don't need the certificate, you don't have to pay for it.
