Immediate success for James Fisher Strainstall's new CWS.

James Fisher Strainstall's new Container Weighing System (CWS) is already proving a success for 'forward thinking' UK port.

Since its recent launch, James Fisher Strainstall’s (JF Strainstall) container weighing system has already become established in the Intermodel/Ports industry. It is currently being used at numerous key UK Ports in the UK including Port of Felixstowe and Tilbury – as well as being considered for integration throughout ports and terminals within Europe, Chile, the USA and Canada.

The system was developed in response to recent talks within the IMO calling for mandatory verification of container weights and utilises JF Strainstall’s 45 years of expertise in designing standard and bespoke load measurement solutions. It has been specifically developed to enable port authorities, shipping companies and couriers to establish the exact weight of containers, as well as the ability to detect eccentric loads. Having this information can help avoid accidents and damage to equipment, stack collapse due to overloaded containers,
poorly loaded vessels consuming additional fuel, and revenue loss for terminals and shipping lines from transporting containers with under-declared weights. 

The Twist-lock variation of the CWS is currently providing accurate data to London Container Terminal (Port of Tilbury) having recently been installed on the ports straddle carrier vehicle. A spokesman from the port says:

"We are very impressed with the high accuracy of the JF Strainstall system and the flexibility JF Strainstall have with regard to other weighing options/methods." 

JF Strainstall’s container weighing system is available in numerous formats enabling the customer to choose the most appropriate and keep their options open. By integrating strain gauge technology with associated instrumentation, an accurate load measurement solution that requires no modification to the standard spreader arrangement is provided. It offers low impact installation and uses a range of display options to allow operators to view live loading and to log/transmit data for analysis at a later stage.

The JF Strainstall container weighing systems are available in a variety of options including:

  • Diaphragm load cell – JF Strainstall can replicate twistlock components such as collars/washers and convert them into load cells. This is a simple non-intrusive solution that provides high accuracy and negates the need for replacements at the end of the recommended service life
  • Load tension twistlocks – the standard spreader or head block twistlock is replicated and supplied as a load sensing twistlock. This negates the need for additional hardware
  • Load pins – JF Strainstall can replace existing load bearing pins within the structure and replace them with load pins, a proven solution for overload protection for decades
  • Truck weighing - a bespoke highly accurate solution typically using compression load cells which can be designed to suit an individual set of requirements
  • Bespoke solutions – A custom built system can be created to meet the customer’s specific needs

Scott Cruttenden, business development manager – industrial sector said:

“We have been very pleased with the high accuracy of data we have seen from our systems within the numerous ports. This has highlighted both the operational value of having our CWS in place as well as the value of ensuring safety during container loadings and ensuring weight is evenly distributed."

The key benefits of the JF Strainstall container weighing system include:

  • Simple non-intrusive integration
  • High accuracy and reliability
  • Optional telemetry versions available
  • Numerous output options
  • View live or store historic data
  • Can be retrofitted
  • Monitors live and eccentric loads
  • Practical calibration in situ
  • Durable/rugged solution to suit environment

Systems specification have been finalised and are due to be installed within the UK’s largest Port – Port of Felixstowe. The ports are ensuring they have solutions in place prior to any mandatory measures being imposed. Tilbury and Felixstowe are two examples of UK ports' forward thinking approach.
