SHIPBUILDING RIGGING SYSTEMS
Naval Construction Rigging Built to Military Standards
Navy shipbuilding demands rigging solutions that meet P307 compliance while solving the fundamental challenges of modular construction. Every pound of rigging weight reduces the potential weight of the ship's section that you can lift. When you're moving 200-ton parts with existing crane capacity, the math is unforgiving. Fifty tons of steel rigging means you can only lift 250 tons of a part, forcing more assembly work at the waterline, where productivity drops.
We manufacture custom high-performance synthetic shipbuilding rigging systems explicitly engineered for naval construction—from large-scale block installation to confined interior hull work. Our navy rigging solutions meet military specifications and complete P307 testing requirements while delivering the weight advantages that enable larger prefabricated sections, reduced waterline assembly, and accelerated build schedules.
Three Key Benefits
- Navy Regulation P307 Compliance/MIL SPEC testing

"I&I Sling has always been great at providing our quotes with a quick turnaround, and their pricing is always the best on the market!" - Steven S.
Confined Space Outfitting
Interior hull work where headroom constraints and access limitations demand specialized rigging solutions, similar to those in industrial manufacturing environments.
Surface Preparation & Coating Operations
Supporting painting and protective coating operations that require precise component positioning and protection from rigging contact damage.
Heavy Load Lifts & Transfers
Moving massive ship components from fabrication areas to assembly positions where precision alignment is critical and margin for error is nonexistent.
Naval Block Installation & Assembly
Large-scale section lifts requiring P307-compliant rigging, with full testing documentation and adherence to military specifications.
Maximize Prefabrication with Lightweight High-Performance Gear
As an authorized Slingmax® Rigging Solutions manufacturer, we engineer high-performance synthetic slings that weigh a fraction of traditional steel, enabling you to:
- Build larger prefabricated sections without upgrading crane capacity
- Reduce waterline assembly work where productivity is 40-60% lower
- Deploy smaller crews for rigging operations
- Complete more outfitting in optimal fabrication conditions
Our Twin-Path Extra slings combine exceptional strength-to-weight ratios with proven 20+ years of field performance for reliability that matters when build schedules span months.
Complete Regulatory Testing & Documentation
P307 compliance demands comprehensive documentation, testing protocols, and design verification that satisfy Navy inspection at every stage. As a certified manufacturer, we provide:
- Full testing documentation meeting military specifications
- Design verification and engineering certification
- Proper tagging and identification systems
- Inspection support and regulatory consultation
- Traceability for all components and assemblies
Our NCCCO-certified outside product advisors bring the same application-based knowledge that end users rely on—because they've passed the same certification tests your rigging crews use. From aircraft carriers to submarines to support vessels, we deliver specialized custom lifting, rigging and hardware solutions with the regulatory expertise and documented compliance that naval construction demands.
Engineering Solutions for Confined Hull Spaces
Outfitting work inside ship hulls can present the same headroom challenges as industrial manufacturing—severe vertical constraints, limited access points, and equipment that must fit through narrow openings. Decades-old vessel designs were engineered for wire rope dimensions. Standard synthetic slings are wider than these original equipment footprints.
We specialize in shipbuilding rigging solutions that fit legacy equipment specifications while delivering synthetic performance advantages. Our Slingmax® Helix® High Performance Synthetic Roundslings are engineered specifically for applications where standard synthetics won't fit—maintaining wire rope footprints while providing superior weight, durability, and handling characteristics for machinery installation in engine rooms and equipment positioning in tight compartments.
