Products

EOM Offshore's mooring components and systems enable a broad spectrum of ocean sensing missions, providing reliable power and data connectivity through the air-sea interface and all the way to the seafloor.  

​

EOM Offshore also can provide field operations, maintenance, and logistics services in support of complete mooring projects.

Mooring Component Products
Universal Joint
Mechanical

  • Termination point for mechanical mooring riser elements such as chain and wire rope

  • Provides a combination of strength and wear resistance for bending under load

  • Permits roll, pitch, and heave without mechanical wear to chain and shackles

  • Constructed of 316 stainless steel with Teflon-impregnated Delrin bushings 

  • Virtually unlimited life with periodic refurbishment

Universal Joint 
Electromechanical

  • Provides a robust electrical and mechanical connection point for E/M riser elements

  • 45 degree deflection in all directions

  • Protected path for electrical conductors along the central axis

  • Available in 6061-T6 aluminum or 316 stainless steel body construction

  • 316 stainless spider and bearing carriers

  • Teflon-impregnated Delrin bushings 

  • Virtually unlimited life with periodic refurbishment

 

E/M Chain

  • Mooring chain strength member encased in durable marine exhaust hose

  • Polyurethane filled for compliance and wear resistance

  • Electrical conductors provide a pathway for power and data

  • Standard sizes and electrical conductor configurations including twisted pairs for Ethernet

  • Custom sizes and electrical conductor configurations available

  • Terminated with standard bolt flanges to eliminate moving parts at connections

  • Enables quiet moorings for passive acoustic applications

 

Mooring Component Products
Stretch Hose Technology

  • Stretch hoses elongate to over twice their original length in normal service 

  • Isolate moorings from surface buoy heave motions 

  • Minimize snap loads in shallow water moorings

  • Replace chain catenary moorings for shallow applications

  • Terminated with standard bolt flanges to eliminate moving parts at connections

  • Enable quiet moorings for passive acoustic applications

  • Bending strain relief built in to terminations

  • Minimize surface buoy watch circle

  • Ideal for sensitive environments such as coral reefs

  • Electrical conductors provide a pathway for power and data

  • Standard sizes and electrical conductor configurations, including Ethernet

  • Custom strengths and lengths available

  • Electrical conductor configurations available

Anchor Recovery System

  • The EOM Anchor Recovery system incorporates a line spool at the mooring's acoustic release, enabling haulback of the anchor

  • When the release is triggered, a line attached to the anchor pays out from the line spool as the bottom of the mooring is brought to the surface

  • Synthetic line of sufficient strength and length is loaded on the spool at EOM using a careful process to prevent fouling

  • Anchor Recovery saves operational funds by re-using deadweight anchors.  In some applications enviornmental permitting requirements may dictate anchor recovery.
