Latch Hawk® Wireless is an innovative fingerboard latch monitoring solution. The wireless network is the first of its kind to provide direct confirmation of fingerboard latch position & condition. The solution is currently being installed globally. The Salunda team assisted one such roll-out on a 6th generation drillship in the Gulf of Mexico.
Latch Hawk® Wireless devices were fitted to the latches by customer personnel. Our unique, patented design meant that devices could be retrofitted through holes in the latch in seconds. Secondary retention is provided by means of the locking nut design.
The onboard team found that this was a quick and simple process and no special training was required to implement a large array of devices in matter of a few hours. A proprietary installation tool was provided which acts as a torque limiting device that ensures the devices were not over, or under, tightened.
The mass of metal from stands of pipe, along with the structure of the derrick, meant that achieving a strong, stable wireless signal presented a challenge to the engineering team during the design phase. The Salunda team overcame this by developing an innovative, proprietary wireless technology. Hundreds of Latch Hawk® Wireless devices form a network that channels data to a HMI display in the drillers cabin.
Notably, the fingerboard monitoring system was ready to go live within hours of starting installation.
Once the system was started the hundreds of Latch Hawk® devices which had been installed were activated. After visual inspection of latches it was confirmed that all Latch Hawk® devices were accurately identifying the correct orientation of their fingers.
Mat Davis, Principal Engineer commented “with normal drilling operations continuing, and with both boards filled with pipe, we were able to install the solution quickly and with the minimum of disruption with in-service reliability. The onboard team were impressed by the intuitive design of the Latch Hawk® and the speed and ease of the installation process.” Mat went on to explain that although Latch Hawk® Wireless is compatible with Profibus it can also run as a standalone system – “The onboard team liked the system’s flexibility and this was a big time saver during commissioning” he explained.
Alan Finlay, Salunda CEO summarised the trip by saying, “the robustness, and speed of installation of Latch Hawk® in an operational environment, was particularly gratifying. We designed with these requirements in mind since, in the current market, fast deployment and high availability reduces costs and minimises disruption to drilling operations. That is vital. We are most grateful to all of our customers for their support and advice”.
