The simple idea that changed the world of load testing.
WATER WEIGHTS®, the load testing specialists now a part of Unique Group, offers a range of bags designed to test everything from cranes to flight deck elevators and from bridges to lifeboats, providing a solution for virtually every load testing challenge.
With over 35 years of global experience, Water Weights has a wealth of expertise to share while offering a comprehensive range of products for rent or sale, worldwide. Water Weights also stocks a large quantity of standard and non-standard load and strain measurement equipment.
Up until the 1970s, it was common practice to use solid weights to test the safe working loads of cranes in the North Sea oil and gas installations. At the end of that decade, WATER WEIGHTS® water-filled proof load bags became the chosen alternative. They were safer, more flexible and since the bags themselves weigh only 2% of the total achievable load when filled – infinitely easier and economical to ship, handle and store.
The innovation that was WATER WEIGHTS® soon became the method of choice for the whole industry. Since then, our company has built on that initial success and expanded its expertise and competence. We now offer a wide range of associated services and engineering project management. Our customer base now includes defense, construction, process, power and utilities, and marine and shipping industries, in addition to the oil and gas business where we originally began.
Our Environmental Responsibility
At Unique Group we are committed to environmental awareness and preservation. We conduct our activities in a manner that manages environmental issues responsibly.
We fulfill this commitment by:
- Lowering the carbon footprint when crane testing compared to traditional methods
- Invasive species mitigation and prevention
- Conducting operations in an environmentally sound manner without disturbing local ecosystems during testing
- Promoting environmental responsibility among our employees
- Pursuing continuous improvement in our environmental performance
Transporting Water Weights water bags to a test site causes considerably less CO2 emissions than using traditional solid weights. We also found out that transporting Water Weights water bags for a 100 ton load test over a distance of 100 miles resulted in 91% reduction in carbon dioxide emissions than solid weights transported by road and 73% reduction in CO2 emissions than solid weights transported by rail.
We also ensure that Water Weights’ inspection procedures addresses the challenge of unintentional introduction of Aquatic Nuisabce Species (ANS) into our waterways through crane testing. These procedures are part of our internal processes certified to ISO 9001:2008.
