The MECO is EOM Offshore's Mechanically Compliant Electromechanical Cable that Stretches through Millions and Millions of Cycles 

Real Time Data from Seafloor-to-Surface

No Disruption in Data and Power Flow

Stretches 2.5 Times Original Length

Bend Fatigue Resistant

Due to its design, the MECO isolates the ocean's rough conditions from the rest of the mooring through millions and millions of cycles.  The key benefit of the MECO is it provides a stable and quiet platform for oceanographic instruments, while reducing the cost of failure, which can lead to unexpected expenditures.  The MECO watch circle is minimal, which eliminates the risk of the mooring line becoming entangled with itself or getting snagged by approaching vessels. 

The MECO cable is patented technology and is the result of decades of research and development at the Woods Hole Oceanographic Institution.  It is unique product that can be part of a larger solution.


The MECO cable is a direct electrical connection that enables the constant delivery of data and power for fixed, real-time measurements from seafloor-to-surface.  Different lengths and conductor arrangements are available, including twisted pairs for Ethernet.   When required, the MECO can allow water from the surface to pass through its hollow center to sampling instruments that are located in the mooring (see our Environmental Sample Processing Mooring).   


The MECO elongates 2.5 times its original length, using mechanical compliance rather than geometric compliance that is used with the traditional catenary mooring.  The MECO provides constant communications and power transmission between underwater instruments and a buoyant object in any weather conditions.  In calm conditions, the MECO returns to its original length, reducing the scope of the mooring and the depth of the water to 1:1.
