James Fisher Strainstall named as New Zealand’s first type-approved integrated weighing system supplier


James Fisher Strainstall (JF Strainstall) – a leading provider of container weighing systems – has successfully achieved full automatic weighing instruments approval in New Zealand for its innovative CWS™ solution. This is now the first type-approved weighing system in the country for reach stackers, straddle carriers, RTGs (Rubber Tired Gantry Cranes) and RMGs (Rail Mounted Gantry Cranes). The system enables container weighing to be accurately completed during stacking operations, removing the need for weighbridges and streamlining the entire process to offer efficiency increases of up to 300%.

Josh Jones, business development manager at Strainstall, said:

Offering full compliance with SOLAS directives, CWS™ reimagines container weighing to give customers a faster, automated solution that takes time-consuming weighbridges out of the equation – along with their single points of failure. This creates an opportunity for ports and terminals to drastically increase profitability and revenue.”

JF Strainstall's CWS™ ensures full compliance with the International Maritime Organization's (IMO) Safety of Life at Sea (SOLAS) regulation for the verification of container weights. In New Zealand, The Ministry of Business, Innovation, and Employment (MBIE) trading standards group approves and certifies weighing equipment and maintains a database of approved systems that now features CWS™.

After investing in CWS™, Diogo Pereira de Castro, director at Yilport Ferrol, said:

From concept to installation, JF Strainstall’s team were responsive, professional and reliable throughout our collaboration. Their solution was equally impressive. Since installation, our container weighing speed has increased three-fold, delivering a faster service for our customers.” 

CWS™’s redesigned VGM (Verified Gross Mass) weighing process enables terminals to benefit from a new, lucrative revenue stream. Leveraging a faster, automated method of VGM verification, ports can now weigh and validate every container’s VGM as part of their existing lifting/stacking cycles without compromising container throughput. This creates a chargeable opportunity whereby ports can charge a processing fee for the VGM verification of all containers handled, as well as allowing them to charge an additional fee for any discrepancies between the actual weight of containers and the weight stated on their VGMs.

Since deploying CWS™, Nick Loader, chief executive officer at DP World Southampton, said:

“We assessed a number of different options to be able to offer a container weighing service to our customers and selected JF Strainstall’s system because it doesn’t require any changes to our port operating procedures and is quick to install. The trials demonstrated an accuracy above our expectations.”

CWS™ offers a host of advantages when compared with alternative solutions:

  • CWS™ can triple the container weighing speed of ports that previously deployed a weighbridge solution
  • The turnkey system enables seamless integration with pre-existing lifting equipment to offer a simple and reliable solution for container weighing
  • With CWS™, all on-site lifting apparatus can automatically provide a precise VGM certificate in real time to further streamline operations, which can implement directly into Terminal Operating Systems (TOS)

Having successfully installed CWS™ at a number of international terminals, including DP World Southampton and Yilport Ferrol, JF Strainstall continues to operate in line with its commitment to supporting safe, efficient, and fully-compliant container weighing on a global scale.
