Necessity of Ultrasonic Watertight Integrity Tester for the Maritime Industry

Businesses rely on transportation and cargo ships. Ships sink, fires happen.

Rust shows up on the boat's lid covers and the diverse parts of its body because of the abnormal state of mugginess and the consistent contact with water. Rust destroys the boat's body creating a reasonable gap that permits water ingress. When water gets inside the boat's body there is no restriction to the harm it can incur on the cargo. These openings are unavoidable, however they are repairable through a procedure and the initial phase in this procedure is the  cable transit areas watertight testing. The significance of these tests is certain and without running these tests maintenance cannot begin.

A watertight hatch cover is designed to prevent the passage of water in either direction under a head of water for which the surrounding structure is designed.  Many mariners may think hatches are robust, monolithic structures, thereby failing to appreciate the small tolerances on panel alignment and gasket compression. It is better to think of hatches as complex, finely-made structures, to be handled with care. All types of seals, experience dynamic stresses as part of their operational lifetime. For example, 4mm wear on the steel-to-steel contact is sufficient to damage rubber sealing gaskets beyond repair; 5mm sag along the cross-joint can cause a large gap between the compression bar and gasket.

The risk is worsened by the ageing nature of many bulk carrier ships in particular. There is also a degree of bending/deformation that naturally occurs in ships during travel, which puts pressure on hatch covers and can damage sealing. A recent wave of inexperienced crew members has swept across the shipping industry as a cost-saving mechanism, leaving vessel maintenance and hatch cover testing to decrease in quality. While hatch covers are often perceived as indestructible due to their large size and bulky exterior, in reality they are complex, finely made structures that need to be handled with care, a point that many mariners do not realise.

Today by utilizing the ultrasonic watertight integrity tester,  the hatches, seals, watertight doors and MCTS can be ensured. With the assistance of the ultrasonic device even the multiple cable transit areas testing  have are testable and the vessel integrity can be ensured.

 

CEO Message

Integrity and Science Key to Our Culture of Performance

Dear Coltraco Customers, Strategic Partners and Distributors,

Integrity is our defining value. Performance is its consequence. We understand that our customers have choices, and how we perform determines whether customers choose us. Coltraco’s Code of Ethics does not merely require compliance with laws. It embodies a Commitment to positive behaviours that build trust, promote respect, operate with distinction, with courtesy and global levels of performance, demonstrating our integrity and delivering customer performance.

We honour our commitments, communicate transparently, and act with honour. Ethics are the foundation of our performance culture and our science-based approach. We lead in specific technologies delivering the watertight integrity monitoring of marine structures and the monitoring of fixed liquefied gaseous fire extinguishing systems and the room integrity of protected space to ensure agent hold-times post-installation. We show this by our understanding of the science in them and the mathematics that explain them.

I would like to thank you for your business and for the relationships with our Customers, Strategic Partners, Distributors and ODAs who we value so highly.

My kindest regards,
Carl
