Why does Lloyd’s Type Approval matter when it comes to Shield’s Hose?

Tuesday, December 30th, 2014

Type Approval from Lloyd’s Register (LR) proves that a product conforms to recognized industry quality standards and/or the LR Rules, through a process of independent design review, testing and verification of production controls.

There are two main steps to Type Approval. The first is Type Examination. Design data is submitted and reviewed to ensure it complies with the requirements of the specified standard(s) and/or LR rules. Then, samples of the product are tested to verify they meet the testing requirements of the relevant standards and any performance requirements associated with the product.

The second main step in the Type Approval process is Production Quality Assurance. This is performed to ensure the product (when mass produced) will be of an acceptable quality and will conform to the version that was prototype tested. Production controls are inspected to confirm that the product can be manufactured in accordance with the design data.

Once Type Approval is achieved, a Certificate is issued and is typically valid for 5 years. The product is then entered in the relevant part of the Lloyd’s Register List of Type Approval Products.

Why does this matter to you? It matters because this certification ensures you that our vendors and suppliers are capable of providing the highest quality product possible. You can trust your boat with Sierra.

Usage, Inspection and Maintenance of Hose Systems

INSTALLATION, INSPECTION AND MAINTENANCE OF HOSE SYSTEMS

Don’t Neglect This Critically Important System On Your Boat

Shields Marine manufactures a wide variety of hoses for applications onboard pleasure craft.  Serving as conduits for fluids, air or exhaust, each Shields hose is designed for a specific application and meets strict standards set by the USCG, ABYC and other regulatory agencies. Hoses also serve as vibration absorbers, isolating components such as exhaust manifolds from the hull of the vessel.

Installers should be mindful of using the right hose for the job. Correct hose and coupling methods should be carried out as outlined by EPA, ABYC, USCG, SAE and the NMMA. Any questions regarding application, replacement or installation should be referred to the Shields technical service department at 217-324-9400.

Inspection
Hose applications aboard any vessel are likely to be mission-critical. Therefore, failure to inspect and replace worn or aged hose can result in the loss of property or possibly, the loss of life.  All mission-critical hose – fuel, wet exhaust, bilge pump, bilge vent and hoses connected below the water line – should be inspected prior to each use of the vessel. All fittings and clamps should be secure and properly attached.  All hoses and connections should be inspected annually by a qualified marine mechanic.

Maintenance and Replacement 
If inspection reveals hose damage, those hoses should be replaced consistent with industry standards.
Replace hose that exhibits any of the following signs:
• Cuts, gouges, cracks
• Exposed fabric or wire reinforcement
• Soft spots or bulges
• Loose covers or kinks
• Stiffness or inflexibility

Installation
Hoses shall be secured by corrosion resistant clamps equal to or greater that 300 grade stainless steel. Clamps shall not depend solely on spring tension. Clamps should not be over-tightened, as this may damage the hose or fitting. Fittings must be the proper size for the hose. Forcing a hose over an oversized fitting or clamping down the hose on an undersized fitting may damage the hose and cause failure.
