Maritime transport is one of the main methods for moving goods globally. To ensure that cargo arrives at its destination in optimal condition, proper lashing and unlashing techniques must be applied. These operations ensure the cargo remains stable during navigation, preventing unwanted movement that could damage the goods or compromise the safety of the vessel and its crew.

Lashing is the process by which cargo is secured to the ship using specific tools and techniques to ensure stability. Unlashing, on the other hand, is the subsequent phase: the cargo is released once it reaches its destination, allowing for safe unloading.

Thanks to its experience and professionalism, SerNavi offers a comprehensive range of lashing and unlashing services, using advanced equipment and highly qualified personnel to handle even the most complex loads.

The transport of oversized cargo requires specialized expertise and meticulous planning to ensure maximum safety. These loads are beyond standard dimensions or weight and cannot be handled with traditional methods. SerNavi manages the lashing of oversized cargo both in the holds and on deck, using customized solutions for every type of load.

Lashing operations for oversized cargo include:

• Preliminary cargo analysis and identification of the best securing techniques.

• Use of appropriate materials and equipment to ensure maximum hold strength.

• Ongoing monitoring during the voyage to ensure the load remains stable.

SerNavi operates in compliance with international maritime safety regulations, delivering high-quality services that minimize the risk of cargo damage.

Effective lashing depends on the use of the right tools. SerNavi supplies everything necessary to ensure cargo is securely fastened and remains stable throughout the journey. Available equipment includes:

• D-rings: anchor rings used to secure ropes and straps.

• Steel cables: robust and resistant, ideal for blocking heavy loads.

• Turnbuckles: adjustable devices used to maintain proper tension in cables.

• Chains: used to ensure secure fastening even in rough sea conditions.

All materials are certified and of high quality, ensuring maximum safety during transport and reducing the risk of cargo shifting or damage.

For certain lashing and unlashing operations, especially those involving large or hard-to-access cargo, cranes and aerial platforms are essential. SerNavi is equipped with the necessary machinery to facilitate loading and unloading operations, ensuring:

• Greater efficiency and speed in handling.

• Enhanced safety for operators and cargo.

• The ability to operate in tight or hard-to-reach spaces.

The use of cranes and aerial platforms allows for precise handling of even the most complex cargo, reducing the risk of accidents or damage.

For oversized cargo or special requirements, SerNavi offers custom fabrication of steel components. Thanks to an expert team, it’s possible to design and build custom elements for securing cargo, offering optimal solutions for every need.

Naval fabrication services include:

• Tailored design based on the customer’s specific requirements.

• Construction of metal structures for cargo securing.

• Quality checks to ensure maximum strength and safety.

This solution allows for complete adaptability to any type of cargo, providing custom anchoring systems that improve transport reliability.

The integrity of welds used in securing structures is essential for load stability. For this reason, SerNavi performs non-destructive testing (NDT) on welds, allowing verification of their integrity without compromising functionality.

Main testing methods include:

• Liquid penetrant testing: detects surface defects in welds.

• Magnetic testing: identifies internal imperfections not visible to the naked eye.

• Ultrasound testing: advanced technology to check the integrity of welded structures.

These tests ensure all welds meet safety standards, preventing potential structural failures during navigation.

An often overlooked but essential part of lashing and unlashing operations is the management of administrative procedures. SerNavi handles the acquisition of all necessary permits from the Port Authority, ensuring full compliance with current regulations.

Key administrative services include:

• Preparation and submission of required documentation.

• Handling of authorizations for oversized cargo transport.

• Coordination with port authorities to ensure regulatory compliance.

Relying on SerNavi means benefiting from a full-service approach that includes not only practical operations but also complete management of bureaucratic aspects.

Lashing and unlashing are crucial operations for safe and efficient maritime transport. With its experience and high-quality services, SerNavi is the ideal partner to ensure cargo safety during navigation. Backed by a qualified team, state-of-the-art equipment, and comprehensive support that includes administrative handling, SerNavi stands out as a leader in the field of maritime lashing.
