150–450 mm Closed Type Two-Roller Shipside Fairlead for Ship Mooring Equipment

150–450 mm Closed Type Two-Roller Shipside Fairlead for Ship Mooring Equipment

Product Overview

JIS F 2014 Form BF BS closed type shipside fairlead with two rollers is designed to change and guide the direction of mooring ropes on ship sides and deck mooring areas. The closed frame helps control the rope path and reduce the risk of rope jumping out during mooring operation, while the two rollers provide smooth rope guidance and help reduce wear on wire ropes, Manila ropes and nylon ropes.

This page is focused on the closed type two-roller configuration. It is different from open type fairleads and three-roller closed type fairleads because the structure is more compact and the rope path is more controlled. The product can be supplied according to JIS F 2014-1987, with roller diameters from 150 mm to 450 mm and customized material or surface treatment options according to project requirements.

Selection Guide

Step 1: Confirm the fairlead type = BF & BS closed type → choose this product when the mooring rope needs a controlled closed rope path instead of an open roller guide.

Step 2: Confirm roller diameter = 150–450 mm → match the nominal diameter with rope size, rope bending route and the ship side mooring arrangement.

Step 3: Confirm roller number = 2 rollers → suitable for compact direction change and rope guidance where a three-roller layout is not required.

Step 4: Confirm rope type = wire rope, Manila rope or nylon rope → different rope materials may require different surface finish and roller contact quality.

Step 5: Confirm material = mild steel, C-Mn steel, stainless steel, casting steel or nodular cast iron → choose according to project specification, corrosion environment and class requirement.

Step 6: Confirm coating = Sa2.5 + epoxy shop primer, galvanized, polished or customized → select the surface treatment according to shipyard painting system and marine exposure condition.

Step 7: Confirm certification requirement = project class certificate or maker test certificate → advise the required classification society before quotation and production.

Structure

Closed frame | Two guide rollers | Roller shaft | Side support structure | Base / mounting structure | Rope contact surface | Protective surface treatment

Design and Quality Advantages

• Closed type structure helps keep the mooring rope within the guide path during operation.

How It Works

Mooring rope enters the closed fairlead opening → rope contacts the guide rollers → rollers rotate and guide the rope direction → closed frame controls the rope path → rope is led safely toward bollard, winch, capstan or shore-side mooring point.

Applications

FAQ

Q1: What is the main difference between closed type and open type shipside fairlead?

A1: Closed type fairlead has a frame that helps control the rope path and reduce the possibility of rope jumping out. Open type fairlead is more convenient for flexible rope entry from different directions. This page is for the closed type two-roller configuration.

Q2: Can this fairlead be used for wire rope, Manila rope and nylon rope?

A2: Yes. The provided product description states that this fairlead can bear wire ropes, Manila ropes and nylon ropes. The final selection should still confirm rope size, rope route and surface finish requirement.

Q3: Which roller diameter should be selected?

A3: The available roller diameter range is 150–450 mm. Selection should be based on the vessel mooring arrangement, rope type, rope size and installation space. If the project is a replacement, the existing fairlead dimensions should be checked against the table.

Q4: Can the material and surface treatment be customized?

A4: Yes. Material options include mild steel, C-Mn steel, stainless steel, casting steel and nodular cast iron. Surface treatment can be Sa2.5 + epoxy shop primer, galvanized, polished or customized according to project requirements.

Q5: What certificate should be requested for quotation?

A5: Please confirm whether the project needs a classification society certificate, maker test certificate or other project documentation. The certificate scope should be confirmed before quotation because it affects inspection, cost and delivery schedule.
