Bulwark Mounted Panama Chock JIS F 2017 Type BP Steel Plate Fabricated

Product Specification

Bulwark Mounted Panama Chock JIS F 2017 Type BP Steel Plate Fabricated

Product Overview

The JIS F 2017 Type BP steel plate fabricated bulwark mounted Panama chock is a ship mooring fitting used to guide mooring ropes through the bulwark area and transfer mooring loads into the ship structure. Compared with deck-mounted Panama chocks, the BP type is arranged on the ship bulwark and transfers mooring load through the steel plate fabricated chock body and welded connection to the reinforced bulwark structure according to the project drawing.

This page focuses on Type BP only. The product should be selected by nominal size, installation position, rope arrangement, material, surface treatment and required classification documentation. The rope-contact surfaces, plate fabrication quality, rib arrangement and welding area near the ship structure should be controlled carefully to reduce rope wear and support reliable mooring operation.

Main Technical Parameters

Selection & Inquiry Guide

Step 1: Confirm the standard and type → JIS F 2017-1982 Type BP, steel plate fabricated and bulwark mounted.

Step 2: Confirm nominal size → 310 or 360, or send the vessel drawing for size matching.

Step 3: Confirm material and fabrication requirement → steel plate grade, welding requirement, rib arrangement and shipyard approval requirement.

Step 4: Confirm surface treatment → shop primer, epoxy system, top coat color, stainless steel option if applicable, or project coating specification.

Step 5: Confirm documentation → Makers Test Certificate, material certificate, inspection record, test report or class certificate if required.

Step 6: Confirm quantity, delivery port, packing method, required delivery time and whether installation drawings or photos are available.

Structure

Steel plate fabricated body | Smooth rope-contact opening | Reinforcing ribs | Bulwark welded connection area | Welding and stopper details | Marine surface coating

Steel Plate Fabrication, Welding & Quality Advantages

• Fabricated Type BP structure follows the JIS F 2017-1982 Type BP arrangement and should not be mixed with AC, AP or BC type structures.
• Smooth rope-contact surfaces are important to reduce rope abrasion during mooring operation.
• Rib position and quantity may be adjusted where the project or shipyard approval requires it, while the standard structure and main dimensions should be kept.
• The welding zone between the chock body and ship structure should be free from defects affecting welding quality, especially within the 50 mm area near hull or bulwark welding.
• Finite element check or strength review can be arranged when the project requires additional verification for shipyard or class approval.
• Sandblasting, primer and marine coating system can be selected according to vessel environment and corrosion protection requirement.

Custom Attributes

• Product Type: Type BP Panama Chock → fabricated steel-plate bulwark mounted mooring chock.
• Standard: JIS F 2017-1982 → suitable when the project specifies Japanese standard Panama chocks.
• Installation: Bulwark mounted and welded to ship structure → intended for mooring rope passage through the bulwark area.
• Fabrication: Steel plate fabricated → different from cast steel Type BC construction.
• Rope Contact Surface: Smooth rounded opening → helps protect mooring rope during guiding and load transfer.
• Inspection: Visual, dimensional and documentation checks → final inspection scope according to order and certificate requirement.

How It Works

Mooring rope approaches the bulwark opening → the smooth Panama chock surface guides the rope → mooring load is transferred through the fabricated body and reinforcing ribs → load is carried into the reinforced bulwark structure through the approved welded connection.

Applications

Cargo vessels | Tankers | Bulk carriers | Workboats | Barges | Shipbuilding projects | Ship repair and replacement | Bulwark mooring stations

Certifications & Advantages

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

Classification certificate, material certificate, inspection record and coating documents are available according to project requirement and subject to class approval scope.

FAQ

Q1: What is the difference between JIS F 2017 Type BP and Type BC Panama chock?

Type BP is a steel plate fabricated bulwark mounted Panama chock, while Type BC is a cast steel bulwark mounted type. They should not be mixed when the project specifies a certain standard type.

Q2: Can the rib quantity or rib position be changed?

The JIS F 2017-1982 Type BP standard note allows rib quantity or position to be changed where necessary. Any change should be confirmed by the shipyard, designer or classification society before production.

Q3: What information is needed for quotation?

Please provide the standard and type, nominal size, quantity, material or coating requirement, certificate requirement, delivery destination, required delivery time, and any vessel drawing or installation photo if available.
