Chocks – Marine Deck Equipment for Safe Mooring
At Veta Gemi A.Ş., we design and manufacture high-quality marine chocks, essential components for ship mooring and towing operations.
Our ship equipment production facility in Yalova, Turkey, delivers class-approved chocks built for strength, durability, and long-term resistance against harsh marine conditions.
Each chock is engineered to ensure smooth rope handling, reduce abrasion, and provide maximum safety during vessel mooring and towing maneuvers.
Reliable and Durable Marine Chocks
The chock is a vital marine deck fitting that guides ropes and cables safely through the hull or deck, preventing direct contact with sharp edges.
At Veta Gemi, our marine chocks are made from premium cast steel and undergo precision machining to meet the highest industry standards.
With a smooth inner surface and strong structure, they minimize rope wear and ensure operational reliability for vessels of all sizes.
Main advantages of Veta Gemi chocks:
High-strength steel construction for extreme durability.
Smooth, machined surfaces to reduce rope friction and abrasion.
Long service life under continuous exposure to seawater.
Available in multiple types and sizes, compliant with ISO 13795 and JIS F 2005 standards.
Types of Marine Chocks
We manufacture a complete range of ship chocks suitable for deck, bulwark, and fairlead applications. Each model is engineered for different mooring configurations and vessel requirements.
Closed Chocks
-
Designed for fixed mooring lines and maximum safety.
-
Fully enclosed casting prevents rope slippage.
-
Ideal for offshore vessels and large cargo ships.
Open Chocks
-
Allows easier rope access and adjustment during mooring.
-
Compact design for use in tight deck spaces.
-
Commonly used on tugs, ferries, and general cargo vessels.
Roller Chocks
-
Equipped with rollers to reduce friction and line tension.
-
Suitable for towing, berthing, and heavy-duty mooring operations.
-
Available in both vertical and horizontal roller configurations.
Panama Chocks
-
Built according to Panama Canal Authority (ACP) standards.
-
Used on vessels transiting the Panama Canal for towing and mooring.
-
Available in both deck-mounted and bulwark-mounted versions.
Engineering and Production Standards
Every Veta Gemi chock is designed using advanced 3D CAD software and validated by Finite Element Analysis (FEA)to ensure strength under extreme loads.
Our in-house marine engineering team guarantees dimensional precision, alignment, and compliance with SOLAS and classification society requirements.
Production involves:
CNC machining and certified cast steel (Grade A / Grade B) fabrication.
Non-destructive testing (NDT) for weld and casting quality.
Surface finishing through shot blasting and epoxy or zinc coating.
Proof load testing under class supervision.
All products are supplied with full documentation — material certificates, WPS/PQR records, test results, and classification approval if required.
Applications
Our marine chocks are suitable for a wide range of vessels and facilities:
-
Cargo ships, tankers, bulk carriers, and offshore platforms.
