Drag Chains for Dynamic Positioning Systems in Ships

Drag chains play a crucial role in ensuring the smooth operation of dynamic positioning systems (DPS) in ships. As ships become more advanced and sophisticated, the need for reliable and efficient DPS becomes increasingly important. This article explores the significance of drag chains in DPS and their various applications in the maritime industry.

The Importance of Drag Chains in Dynamic Positioning Systems

In dynamic positioning systems, drag chains are utilized to protect and manage the cables and hoses that power and control the ship’s equipment. These systems enable vessels to maintain their position and heading without the need for anchoring, offering enhanced maneuverability and operational flexibility.

Drag chains serve as a protective casing for the cables, preventing them from tangling or getting damaged due to external factors such as harsh weather conditions, vibrations, or abrasion. Moreover, these chains ensure the organized routing of cables, reducing the risk of accidents and facilitating easy maintenance and repairs.

Applications of Drag Chains in the Maritime Industry

Drag chains find extensive applications in various areas of the maritime industry. Let’s explore some of the key scenarios where drag chains are essential:

1. Offshore Oil and Gas Platforms

In offshore oil and gas platforms, drag chains are critical components in the DPS, ensuring the uninterrupted supply of power and control signals to equipment such as cranes, winches, and drilling systems. These chains safeguard the cables from the corrosive marine environment and extreme weather conditions, guaranteeing reliable performance even in harsh offshore environments.

2. Shipbuilding and Ship Repair

During the shipbuilding process, drag chains are employed to organize and protect the numerous cables required for the ship’s systems, including propulsion, navigation, communication, and safety equipment. In ship repair operations, drag chains facilitate efficient cable replacement and maintenance, reducing downtime and costs.

3. Research Vessels and Offshore Support Vessels

Research vessels and offshore support vessels rely on precise positioning for scientific research, exploration, and complex offshore operations. Drag chains ensure the uninterrupted supply of power and control signals to critical equipment, such as sonar systems, ROVs (remotely operated vehicles), and other specialized instruments.

4. Cruise Ships and Luxury Yachts

Drag chains are crucial in maintaining the smooth operation of entertainment systems, lighting, HVAC (heating, ventilation, and air conditioning), and other amenities on cruise ships and luxury yachts. These chains provide a reliable and organized cable management solution, enhancing passenger comfort and safety.


Drag chains are indispensable components in dynamic positioning systems for ships. Their robust design and efficient cable management capabilities ensure the reliable and safe operation of vital equipment. Whether in offshore platforms, shipbuilding, research vessels, or luxury yachts, drag chains play a pivotal role in streamlining operations and enhancing efficiency in the maritime industry.
