Product Specification

9-Roller Universal Fairlead for Ship Mooring & Towing | CB*3062-79 Type E

Product Overview

The CB*3062 Type E marine 9 roller fairlead is a universal roller fairlead for ship mooring, towing rope guiding, and multi-direction rope lead arrangements. It is fitted at the shipside of the freeboard deck and uses five vertical rollers with four horizontal rollers to guide ropes from seven directions while reducing direct friction between the rope and fixed deck structure.

Compared with common three-roller or four-roller fairleads, the Type E nine-roller arrangement provides a wider rope guiding envelope for complex mooring stations, tug and workboat deck layouts, offshore support vessel arrangements, and naval or commercial ship applications. The product can be used with steel wire ropes and nylon ropes according to the supplied diameter range; final load basis, deck reinforcement, welding detail, bearing arrangement, coating system, and certificate scope should be confirmed according to the vessel drawing and project requirement.

Selection & Inquiry Guide

Step 1: Confirm CB*3062-79 Type E nine-roller universal fairlead and the required steel wire rope or nylon rope diameter.

Step 2: Confirm rope lead direction, shipside / freeboard deck installation position, mooring arrangement, and whether the fairlead is for newbuilding or replacement.

Step 3: Confirm design load basis, rope MBL, reference SWL requirement, deck reinforcement, welding interface, and available installation space according to vessel drawing.

Step 4: Confirm material grade, roller / shaft / bearing or bushing requirement, lubrication arrangement, and corrosion protection requirement.

Step 5: Confirm surface treatment, final coating system, galvanized or stainless steel option, quantity, delivery destination, and required delivery time.

Step 6: Confirm certificate and inspection scope before quotation, including maker certificate, material certificate, class certificate, witness inspection, or project-specific approval requirement.

Structure

Welded / fabricated fairlead frame | 5 vertical rollers | 4 horizontal rollers | Roller shafts | Bearing or bushing position to be confirmed | Rope-contact roller surfaces | Shipside deck installation interface | Marine coating or specified surface treatment

Mooring, Towing & Engineering Advantages

• The nine-roller layout combines vertical and horizontal rope-contact surfaces, making it suitable for complex rope lead angles where the rope may approach from different deck directions.

• Free-turning rollers help reduce sliding friction against the fairlead body and support better protection for steel wire rope and nylon rope surfaces during mooring or towing operations.

• The Type E arrangement provides a wider guiding range than common three-roller or four-roller fairleads, which is useful for shipside mooring stations with limited rope alignment control.

• Roller, shaft, and bearing / bushing areas should be designed for inspection, lubrication, and maintenance access so that roller rotation remains reliable during vessel operation.

• The fairlead should be selected together with rope diameter, rope MBL, lead angle, deck reinforcement, welding detail, and class inspection requirement; the rope breaking load should not be directly treated as product SWL.

• Surface preparation and coating can be matched with the vessel painting specification, while stainless steel or galvanized surface treatment can be discussed for special corrosion or maintenance requirements.

• Classification inspection, material traceability, and witness testing can be arranged according to project requirement and class approval procedure.

Custom Attributes

• Standard: CB*3062-79 → use when the vessel drawing or shipyard specification calls for this universal roller fairlead standard.

• Type: Type E → nine-roller configuration with five vertical and four horizontal rollers.

• Rope Compatibility: steel wire rope and nylon rope → select according to the supplied rope diameter range and vessel mooring design.

• Installation Position: shipside of freeboard deck → deck reinforcement and welding interface should be checked by the shipyard or design office.

• Load Basis: to be confirmed → SWL, rope MBL, safety factor, and test requirement should follow the project specification and class approval.

• Material: C-Mn steel / mild steel / stainless steel → final grade and material certificate scope should be confirmed before production.

• Roller Maintenance: inspection and lubrication access to be confirmed → important for maintaining free roller rotation and reducing rope wear.

• Surface Treatment: Sa 2.5 blasting + epoxy shop primer as reference → final coating, galvanizing, polishing, or other treatment follows customer requirement.

• Certificate Requirement: available according to project requirement → certificate type and class witness scope should be confirmed before quotation.

How It Works

Mooring or towing rope approaches from the deck direction → Rope contacts the vertical and / or horizontal rollers → Rollers rotate to reduce sliding friction → Rope is guided through the required lead path → Contact force is transferred through the fairlead frame to the reinforced deck structure

Applications

Commercial ships | Naval vessels | Offshore support vessels | Tugboats | Workboats | Shipside mooring stations | Towing rope guide positions | Newbuilding and replacement projects

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: Is the rope diameter range the same as the product SWL?

A1: No. The supplied table provides applicable steel wire rope and nylon rope diameter ranges, dimensions, and weight. SWL or reference load should be confirmed separately according to rope MBL, design safety factor, lead angle, deck reinforcement, weld detail, and class requirement.

Q2: Why select a nine-roller fairlead instead of a three-roller or four-roller fairlead?

A2: A nine-roller fairlead is used when the rope path changes from multiple directions and the mooring station requires a wider guiding range. The combination of vertical and horizontal rollers helps reduce rope abrasion and improves rope path stability under complex deck arrangements.

Q3: What information is needed before quotation?

A3: Confirm standard and type, rope diameter, rope type, load basis, material grade, surface treatment, quantity, installation drawing, certificate requirement, delivery destination, and required delivery time. Photos or drawings of the existing fairlead are helpful for replacement projects.
