Hatch Gas Springs

HATCH GAS SPRINGS

Hatch Gas Springs

Problem: Watertight hatches often require two persons to open and secure in the upright position due to their weight. Springs used on some of these hatches contain Berylium (a HazMat) and are prone to breakage. Numerous injuries occur annually when hatches accidentally drop on people.

Solution: Commercial gas cylinders (such as on car hoods and hatches) are available that meet the Navy’s requirements.Specifications would be developed and testing conducted to confirm reliability.

Benefits

Estimated Navy Cost Avoidance

This is a safety issue and no quantifiable cost savings can be identified. However, uncontrolled hatch drops can cause serious damage to seals and hinges.

Fleet Impact: Significant reduction in injuries caused by falling hatches. Undefined reduction in maintenance costs. Reduction in number of people required to raise and lower hatches.

Status: Ongoing

The design for the 30 x 60 inch raised watertight hatch has been completed. A contract to deliver four cylinders will be awarded in the next month.
