EchoMax - radar reflectors

Echomax In Action

Echomax COMMERCIAL the professionals choice

Eason Marine have been manufacturing navigation buoys for over 20 years. Over this period we have strived to achieve a high performance product. One of the most important parts of the navigation buoy is the radar reflector. When we fitted the Echomax Radar Reflector we were so impressed by their performance that we now use them as standard on all EM buoys. In fact many port authorities have commented on the large RCS given by the Echomax Radar Reflector. Through comparative sea trials we know the performance of Echomax Radar Reflectors exceeds their rivals. The Echomax Radar Reflector is probably the best in the world.

Eason Marine Polyethylene 2.4m buoy in the Tees & Hartlepool harbour approaches

Andrew Ridley, Conservancy Operations Manager of Tees & Hartlepool Port Authority Limited first discovered Echomax at Seawork 2001. He was so impressed with their QinetiQ test results and a series of on-site tests that he insisted Echomax arrays were fitted into all the new Eason Marine buoys which he was in the process of ordering. Eason Marine, probably one of the largest suppliers of navigation buoys in the U.K, modified their top marks and cases to suit the EM230/305 arrays. Since they have been laid he has received unsolicited compliments regarding both the radar response and visibility of these units. It was confirmed that the radar response from the Eason Polyethylene 2.4m maintenance free buoy fitted with Echomax arrays was at least equal to if not better than 3m steel buoys fitted with 32" octahedral reflectors. (It is probably only the sheer mass of the metal buoys which has enabled the octahedral reflectors to be fitted for so long).

Mr. Ridley was also receiving complaints from the Harbourmaster when another commercially available reflector fitted to a GRP pilot boat built in 2000 provided inconsistent response resulting in loss of the traces on the VTS radar.

reflector, built into the radar/mast structure on the wheelhouse roof.


As there was insufficient mast height to fix a standard EM305, a customised 305 was fitted into a GRP roof box/mast support. Although additional height above sea level would have been beneficial it was reported that the EM305 gives a much improved response signal. An EM305 fitted to a fixed wooden finger jetty has enhanced the radar signal through all tidal states and avoids the reflection being lost when a combination of high tide and sea clutter would otherwise have caused problems to approaching vessels. (Andrew Ridley is too much a gentleman to state that the poorly performing radar reflectors he removed from his vessels were Firdell Blippers 210-5, 210-7 and Firdell Pilot 300's).

New white and orange Echomax 230's have now been fitted to all seven vessels in Tees & Hartlepool Port Authority's pilot and workboat fleet to comply with SOLAS Chapter V regulation 19.

Sea Trip on Trinity House vessel Vectis to view Barrow - Black Deep 7 fitted with Echomax EM 305 Top mark

After just one and a half hours steaming from Harwich on the Trinity House Vessel Vectis, Black Deep 7, green channel buoy was picked up 6.84 miles ahead. The Skipper of Vectis remarked that Echomax radar response was brighter than 11m Sunk Tower beacon with top mark. Half a mile closer we picked up the response of corresponding Trinity House Red Inner Fishers buoy. The very calm sea conditions did not demonstrate the superior response given by Echomax at heel.
All parties are aware that the Decca scanner is set very low on the Vectis mast and had this been higher all objects may well have been picked up earlier.

Deployed in Liverpool Bay the unit is used to monitor water quality. Data is telemetered back to Cefas every 2 hours and used in assessments and modelling projects.
There are currently 6 active SmartBuoy sites and there are smaller guard buoys to mark bottom lander deployments. Cefas have stated they like to use Echomax radar reflectors on all their buoys, due to the improved performance over the conventional design, and get a radar return from about 3NM in good conditions. They hope this makes the buoys more visible to shipping and thus avoid being hit!

Echomax comment – The reflector mounting height is only 2m considerably reducing the distance response.


Echomax Top Marks

The Echomax Top Mark is ideal for new buoys or upgrading existing ones and is available in pedestal mount for land based or harbour hazards. During the development of the Tees & Hartlepool buoys, Eason Marine were so impressed with the Echomax sea trials they now recommend them as a standard fitting on all new Polyethylene buoys. Echomax reflectors have been supplied to Pharos, Tideland, Hippo, E.Y.E., Balmoral and Mobilis. Nigeria and Iran are just two of the countries worldwide to use Echomax reflectors.

EASON BUOYS ADAPTED TO ACCOMODATE ECHOMAX 230 ARRAY
Echomax arrays have been fitted into commercial marine buoys and are already in Bantry Bay, Cowes, West Coast of Scotland, Tees and Hartlepool Port and Malta. Andrew Ridley, the Conservancy Operations Manager confirms that from a pilot boat radar the response from an Echomax EM230 array fitted in an Eason 2.0m Polyethylene buoy exceeds that of a 2.4m steel buoy with an Octahedral reflector.
