DDL OMNI has a strong capability in the development and
application of metallic and non-metallic materials for military
and commercial systems. Our engineering personnel are highly
experienced in ship, submarine, and amphibious/ground vehicle
design and engineering from concept through construction
and testing.
The DDL OMNI materials engineering team includes experts
in metals and welding, marine corrosion prevention and control,
and composites. Our capabilities include fatigue and fracture
analyses, structural integrity assessments from a metals
perspective, computer-aided design (CAD), solid modeling,
material selection for complex marine systems, corrosion
test planning, and testing.
DDL OMNI has been a major contributor to the resolution
of significant U.S. Navy structural integrity problems and
in the development and certification of new material technologies
for U.S. Navy ship and submarine systems. Examples of the
impact of the DDL OMNI materials engineering team include—
- Resolution of hull weld cracking during construction
of USS SEAWOLF (SSN 21).
- Development and certification of under-matched strength
welding for reduced cost welding of VIRGINIA Class submarine
pressure hull structures.
- Structural integrity assessments of high strength steel
and alloy titanium submarine pressure boundary components.
- HSLA-65 Steel Structural Certification Program for CVN
Weight Reduction.
The high-quality materials engineering services provided
by DDL OMNI to the Navy has resulted in significant savings
in cost, schedule, and performance.
In addition to our Navy customers, DDL OMNI provides materials
engineering consultation and development support to private
industry. The support includes—
- Engineering assessment that identified causes and presented
options for eliminating tank level indicator corrosion
in saltwater compensated fuel tanks.
- Engineering consultation for testing to resolve corrosion
on marine grade aluminum alloys.
- Redesign a tactical mobile radar platform pedestal
using composites to reduce structural weight by up to
15 percent.
Our Materials Engineering capabilities include Metals and
Welding, Marine Corrosion Prevention and Control and Composites.
