Marine Forged Welded Oval Eye Plate for Ship Deck Mooring and Rigging Connections

Marine Forged Welded Oval Eye Plate for Ship Deck Mooring and Rigging Connections

Product Overview

The Marine Forged Welded Oval Eye Plate is a welded ship deck attachment fitting used for fixing rope terminals, shackles, pulleys and other marine connection components. It is designed according to JIS F3410-1999 Type F and is intended for installation on reinforced ship structures where a compact welded connection point is required.

The Type F design uses a forged oval eye body with an elongated opening and a welded base arrangement. This structure is different from a simple plate-cut pad eye. The forged shape, smooth radius transition and oval opening help provide practical clearance for shackles and rope terminals while supporting stable load transfer around the eye area.

This product is suitable for shipyards, vessel owners, marine equipment distributors and engineering buyers who need a standard-based welded eye plate for deck connection, mooring attachment and marine rigging applications. Final material grade, welding scope, inspection scope and certificate requirements should be confirmed according to the project specification.

FAQ

Q1: Is this product the same as a lifting pad eye?

No. This Type F product is mainly described as a ship oval eye plate for marine fastening and connection applications such as rope terminals, shackles and pulleys. If it will be used for lifting, the load direction, safety factor, welding design and class approval should be separately verified.

Q2: How should I select the correct nominal size?

Selection should start from the required permissible load and the connection hardware size. The standard table gives nominal sizes 3, 5, 7.5, 10 and 15 with permissible loads from 29.4 kN to 147 kN. The installation structure and load direction should also be checked.

Q3: Why is the forged structure important?

A forged eye body provides better structural continuity around the oval eye opening compared with a simple flat plate shape. This is useful for marine connection points where the component may experience concentrated load transfer through shackles or rope terminals.

Q4: Can stainless steel material be supplied?

Yes, stainless steel material can be considered when higher corrosion resistance is required. The exact grade, mechanical properties and certificate scope should be confirmed before quotation.

Q5: What information is needed for a fast quotation?

Please provide nominal size or permissible load, quantity, material, coating requirement, certificate requirement, installation position and destination port. A drawing or application photo will help confirm the correct configuration.

Q6: Which documents are normally public downloads and which are inquiry-based?

The datasheet and simplified GA drawing can usually be prepared for website download. Material certificates, heat number records, WPS information and class certificate samples are normally provided after inquiry or project confirmation because they may contain project-specific or factory-sensitive information.

Important Engineering Notes

• This product is a welded marine attachment fitting. The supporting deck or steel structure should be strong enough to transfer the applied load.

• Permissible load should not be treated as rope MBL, test load or lifting SWL unless separately verified by engineering calculation and class approval.

• Load direction is important. Side loading, inclined loading and repeated dynamic loading should be checked according to the actual installation arrangement.

• Welding leg size, dimensional tolerance and inspection requirements should follow JIS F3410, approved drawings, shipyard welding procedure and class requirements.

• Deck reinforcement may be required depending on the installation position, plate thickness and load path.

• Sa2.5 blasting and epoxy shop primer are preparation treatments. The final coating system should match the vessel painting specification.
