Bolted Mooring Kevel for Inland Vessels | Cast Metal Deck and Bulwark Type (GB

Product Specification

Bolted Mooring Kevel for Inland Vessels | Cast Metal Deck and Bulwark Type (GB 2026)

Product Overview

The GB 2026 bolted type mooring kevel is a compact cast mooring fitting used on inland vessels, small workboats, service boats, barges, berths, and marina mooring positions. It can be installed on a deck or bulwark by bolts, providing a simple mooring point where the rope needs to be fastened without a welded bollard base.

This kevel is normally selected by rope diameter, material, mounting position, available installation space, and the strength of the supporting deck or bulwark structure. The supplied table covers cast copper and cast steel versions with maximum Malina rope diameter up to 75 mm and weight from 1.33 kg to 11.2 kg. For safe mooring use, the bolt arrangement, backing plate or local reinforcement, and certificate scope should be confirmed according to the project requirement.

Quick Specifications

• Product type: Bolted mooring kevel → compact deck or bulwark mooring fitting for inland vessels and small boats.
• Technical standard: GB 2026 → reference for dimensions, rope diameter selection, material options, and model confirmation.
• Installation form: Bolted mounting → easier installation and replacement than welded fittings when the supporting structure and bolt arrangement are suitable.
• Reference rope size: maximum Malina rope diameter 30 / 35 / 50 / 75 mm in the supplied table → final rope size should be checked against the vessel mooring arrangement.
• Material options: cast copper, cast bronze, cast C-Mn steel, cast stainless steel, and nodular cast iron → select according to corrosion environment, wear requirement, and project budget.
• Weight range: 1.33 kg to 11.2 kg → suitable for small and medium mooring positions where compact size and simple handling are required.
• Surface treatment: Sa 2.5 blasting + one layer epoxy shop primer, galvanized, polished, or customized finish → final surface treatment depends on material and order requirement.
• Certificate scope: CCS, NK, BV, ABS, DNV, LR, KR, IRS, RS and other certificates can be arranged according to project requirement, not as a default supply item.

Main Technical Parameters

Selection & Inquiry Guide

Step 1: Confirm GB 2026 bolted type mooring kevel and the required rope diameter according to vessel drawing or berth arrangement.

Step 2: Confirm installation position: deck-mounted or bulwark-mounted, including available base space, plate thickness, backing plate, and access for bolt tightening.

Step 3: Confirm material requirement: cast steel, nodular cast iron, cast copper, cast bronze, cast stainless steel, or other project-specified material.

Step 4: Confirm surface treatment: shop primer, galvanized finish, polished finish, final paint system, or other customer-specified treatment.

Step 5: Confirm certificate and inspection scope before quotation: maker certificate, material certificate, class certificate, UT / MT inspection, or witness inspection if required.

Step 6: Provide quantity, application vessel type, installation drawing or photo, delivery destination, and required delivery time.

Structure

Cast kevel body | Twin mooring horns | Smooth rope-contact radius | Bolted mounting base | Deck or bulwark installation interface | Optional cast steel / nodular cast iron / copper alloy material | Shop primer, galvanized, polished, or specified finish

Casting, Installation & Engineering Advantages

• Bolted installation allows the kevel to be fitted on a deck or bulwark without welding the product body, which is useful for small vessels, replacement work, and compact mooring positions.
• The cast body is suitable for rounded horn transitions and continuous rope-contact surfaces, helping to reduce sharp local contact during mooring operation.
• Smooth transition at the curved areas should be controlled during casting, fettling, and finishing to reduce stress concentration and improve rope-contact behavior.
• Cast steel provides a robust option for small vessel mooring fittings, while nodular cast iron can be considered where wear resistance and casting stability are important.
• Copper alloy or stainless steel versions can be discussed for projects requiring improved corrosion resistance or a specific appearance.
• The bolted connection should be reviewed together with bolt diameter, bolt grade, corrosion protection, backing plate, and local deck or bulwark reinforcement.
• UT, MT, dimensional inspection, material traceability, and FEA-based review can be arranged according to project requirement when the customer specifies inspection or strength verification.

Custom Attributes

• Standard: GB 2026 → use when the shipyard or owner specification requires this bolted type mooring kevel standard.
• Installation: Deck or bulwark bolted type → suitable when simple installation, replacement convenience, and compact footprint are required.
• Application: Inland vessels and small boats → intended for mooring use on small and medium mooring positions, not for lifting.
• Rope Size: Maximum Malina rope diameter up to 75 mm in the supplied table → confirm final rope type and diameter before production.
• Material: Cast steel / nodular cast iron / cast copper / cast bronze / cast stainless steel → select according to corrosion, wear, cost, and project requirement.
• Surface Treatment: Sa 2.5 blasting + epoxy shop primer, galvanized, polished, or customized → finishing method depends on selected material.
• Inspection: UT / MT / dimensional check available upon request → inspection scope should be stated before quotation.
• Customization: Available according to drawing or sample → non-standard dimensions, material, coating, and certificate scope should be confirmed.

How It Works

Mooring rope is led around the kevel horns → Smooth curved contact surfaces guide and support the rope → Mooring force is transferred through the cast body → Bolts and backing structure transfer the force to the deck or bulwark → Periodic inspection checks bolts, coating, and rope-contact wear

Applications

Inland vessels | Small workboats | Barges | Harbor service boats | Marina berths | Deck mooring points | Bulwark mooring points | Small boat replacement projects | Workboat berth mooring arrangements

Certifications & Advantages

Certificates can be arranged according to project requirement, inspection scope, material traceability, and class society approval procedure.

Certification: CCS, NK, BV, ABS, DNV, LR, KR, IRS, RS, RINA, CRS, Makers Test Certificate.

FAQ

Q1: Can this bolted mooring kevel be installed on both deck and bulwark?

A1: Yes. It can be used for deck or bulwark installation when the supporting structure, bolt arrangement, backing plate, and available installation space are suitable. The final installation should be checked according to the vessel or berth arrangement drawing.

Q2: How should the correct size be selected?

A2: Select the kevel by GB 2026 standard, rope diameter, material, installation position, and available mounting space. The supplied table gives maximum Malina rope diameter, main dimensions, and weight. If a project requires a defined working load, the load basis and bolted connection design should be confirmed separately.

Q3: What information is needed before quotation?

A3: Please confirm standard, rope diameter, material, surface treatment, quantity, installation position, bolt requirement, certificate scope, inspection requirement, delivery destination, and required delivery time. A drawing, sample photo, or existing replacement part photo is helpful.
