First Coast Guard District The Omega Gauge Project

OMEGA Gauge Background

• Omega Gauge Project
• Commissioned by the Sea Fisheries Department of Belgium (2002)
• Findings
• Commissioned to replace the ICES Gauge (in Europe)
• European Union Regulations
• No. 517/2008 (published 11 June 2008) mandated the use of the electronic mesh gauge
• Manufacturer
• Observator
• Countries that use the Omega Gauge:
• Germany, Netherlands, Belgium, France, Spain, Portugal, Italy, United Kingdom, Poland, Denmark, Lithuania, Latvia,

Greece, and Finland.

OMEGA Gauge

Omega Gauge Weight and Spade Omega Gauge Benefits

• Quicker than the traditional weight and spade
• Significantly reduces human error
• Precision to 1mm (0.039 inches)
• Reduced boarding team equipment by 60 lbs
• No complications in the water borne environment

Analysis

• Pierside: 19 LMR boarding officers conducted comparative net

mesh measurements (80 each) with the Weight/Spade & Omega Gauge

• Underway (operational): Two USCG cutter crews conduct 13

boardings with Omega Gauge (03 full 20 mesh boardings)

• Overall, Omega Gauge measurements were, on average, .1

inches larger than Weight/Spade measurements

• Overall, Omega Gauge measurements resulted smaller

standard deviation (less variation amongst measurements)

Pierside Data Summary Data Set Avg STDEV Avg (in) Average Time (sec) Spade A 0.175 5.66 237 Omega A .072 5.77 190 Spade B .125 5.67 199 Omega B .0619 5.77 192

• Data set comprised 1,520 total

measurements from 19 boarding

• fficers
• Each boarding officer conducting the test completed a total of 40 measurements with the weight and

spade and 40 measurements with the Omega (Rows A & B)

• 19 boarding officers ranging in experience from 3 months to 10 years participated in the test.

OMEGA Gauge/Weight & Spade Operational Comparison Results

Operational Results Omega Gauge Time Diff* 50% faster

• Omega Gauge versus weight and

spade Operational Results Omega Gauge Weight and Spade Average Mesh Measurements 6.14 inches 6.12 inches

• Data set comprised 120 total

measurements from 03 at-sea boardings

• Two 6.5 inch nets/One 5.5 inch net were

measured during the Operational Testing
