We Provide the Solutions You Need

For more than 60 years, Jered has provided technical solutions for mission-critical systems on every Surface Combatant. We are dedicated to delivering the best in quality and functionality at Jered. Design and engineering drives our work and the only option is delivering complex systems that consistently and reliably deliver for our customers.

Jered focuses on providing marine customers with specialty equipment, cargo handling systems, and deck machinery while combining its strong engineering with comprehensive heavy fabrication capabilities.

Steering Gear Systems

The operation of steering gear equipment is of critical importance to the safety and well-being of the entire ship. Hydraulic ram-type steering gear is used on the US surface combatant fleet due to its proven reliability and multi-layered, fail-safe operation needed in one of the top two systems onboard ship. This system is available in single rudder-tiller connections or as dual rudder-tiller operating systems.

ADDITIONAL FEATURES

An optional capstan head can be located above the wildcat and be operated independently via the wildcat clutch. The capstan design can handle a tow of up to 300,000 lbs while a brushless permanent magnet motor (directly coupled to a gear reducer) drives the anchor windlass. Above and below brake control stations are provided.

The unit has a PLC-driven digital chain counter system with a display at the deck control station. The control station is equipped with a variable-speed joystick and all the necessary lights and push buttons for safe operational control.

COMFIRE® Marine Fireproof Technologies

Marine Fireproof Panels

Marine Systems Technology (MST) originally developed COMFIRE® for marine applications, believing that the COMFIRE® marine fireproof technology would be an ideal way to meet newly imposed (and very stringent) safety requirements for new vessels. A fireproof material, COMFIRE® is also noncarcinogenic and can be recycled.

Noncombustible Fireproof Product

By combining these complementing attributes with stability in water, good acoustic attenuation, and a weight advantage over current materials, COMFIRE® is a world-leading product that complies with the tightest safety guidelines and offers many practical advantages to Naval applications and the defense industry, along with demanding commercial marine applications.

Throughout COMFIRE® utilization and testing, it has been utilized and tested, it has become clear that Marine Systems Technology (MST) developed an ideal solution for anytime a lightweight, noncombustible product would be advantageous.

COMFIRE®: Made To Fit Your Existing Doors

MST has developed an N30 Retrofit Kit specifically for the US Naval market. The Retrofit Kit is based on the successfully tested MIL-STD-3020 N-30 door and meets US Navy requirements for high-impact, medium-weight shock as well as hydrostatic tests. Each Retrofit Kit is customized for your needs and installed by a qualified Jered Service Technician.

LITHIUM-ION BATTER FIRE PROTECTION

Lithium-Ion Battery Lockers
The Lithium-Ion Battery Charging and Storage Locker was designed to house and store a variety of Lithium-ion aircraft batteries of various types, sizes, and shapes. Two tests were conducted for this qualification: 75 minutes at an average of 80 kW heat flux, and a further extreme “overtest” for 8 minutes at an average of 207 kW heat flux.

The system exceeded expectations at 80 kW and again at 207 kW, which is greater than 250% above the average heat flux the Li-ion battery can generate under “heat excursion” conditions. The temperature in the other adjacent compartments reached only 19.5°C (67°F) at the highest point during the first test. The second “overtest” again revealed excellent thermal properties with the maximum temperature of 33°C (91°F) recorded in adjacent compartments – some 82°C (180°F) below the test acceptance criteria.

The outside of the cabinet was cool to the touch during testing and the system remained fully functional post-test.
