Collaborating for almost two decades MacArtney and the Applied Physics Laboratory at the University of Washington has recently launched the FOCUS 3 – APL’s latest acquisition in the pursuit of unexploded ordnance detection.

Over the years, APL and MacArtney have worked together on several projects with a comprehensive scope of supply from MacArtney including the TRIAXUS and FOCUS ROTVs, CORMAC winch launch and recovery system with Focal Slip Ring, SubConn® connectors and fibre optic cabling; often providing specific system solutions and sensor packages tailored to APL’s specifications.

Reflecting on the years of collaboration Lars Jorgensen, Sales Manager System Solutions, MacArtney A/S states,

“Our very good working relationship with The University of Washington Applied Physics Laboratory has been both fruitful and constructive. Going back to the delivery of the TRIAXUS vehicle, the APL team contributed with amazing ideas and suggestions for operational details and application setups during the final stages of prototype testing.

Very often pushing the final product and its application to a higher level”.

From the University of Washington’s Applied Physics Laboratory, Tim McGinnis, Head of Ocean Engineering Department & Senior Principal Engineer states,

“The University of Washington Applied Physics Lab has been working with MacArtney and their remotely operated towed vehicle systems since our purchase of a TRIAXUS in 2003. We were pushing the TRIAXUS to its performance limits, and we had some challenges, but we were very impressed with MacArtney’s diligence and commitment to working through them.

The TRIAXUS has proven to be a very functional and durable system. The TRIAXUS system is easy to customise for different instruments and scientific investigations and is currently being used on a research cruise in the North Atlantic near Iceland. We are currently developing an advanced sonar to identify buried objects, and the FOCUS 3 was a near perfect solution. It provides a good platform for mounting our sonar electronics and transducers, controllable and stable towing and flexible power and data transmission options for a variety of subsystems and instruments”.

After 40 years of industry experience, MacArtney places a high value on fostering professional and collaborative relationships within the ocean space communities and industries. MacArtney continually strives to serve customers and provide system solutions to meet their varied needs.
