Chain Pipe (Deck to Locker)
For chain 46-97mm · Deck Hardware · spurling chain pipe
Type
chain_pipe
Chain range (mm)
46-97
Common Failures & Inspection Points
  • Internal wear lining failure
  • Flange bolt corrosion
  • Water ingress to chain locker
Service: Line with HDPE or cast steel; ensure watertight integrity.
Spare Parts: Ersatzteile über Generic (Class Approved) oder zugelassene Vertriebspartner. Lead time: 2-6 Wochen.
Strengths
  • Class approved for compliance with SOLAS/IMO requirements
  • Accommodates a wide chain size range (46–97 mm) in one unit
  • HDPE or cast‑steel liner provides low friction and corrosion resistance when properly maintained
  • Watertight flange design helps prevent water ingress to the chain locker
  • Standardised dimensions simplify installation on many vessel types
Weaknesses
  • Internal lining can wear over time, leading to reduced protection and possible failure
  • Flange bolts are prone to corrosion if not stainless or regularly inspected
  • Water ingress may still occur at flange joints if sealing is compromised
  • Limited documentation for non‑standard chain sizes outside the 46–97 mm range
  • Generic design may lack advanced monitoring features (e.g., strain gauges) found on premium models
Typical Vessels: TankerBulk CarrierContainer ShipGeneral Cargo VesselOffshore Supply Vessel
Decision Guide: Choose if: you need a proven, class‑approved chain pipe for standard deck‑to‑locker applications, the vessel uses chains within the 46–97 mm range, and budget favours a conventional solution. Avoid if: operating in highly corrosive environments, require integrated condition‑monitoring sensors, or need custom sizing beyond the listed range.
Use Cases: Installed on the deck to route anchor or mooring chain into the chain locker, providing a protected, watertight path that reduces wear and prevents water ingress during heavy sea states. Commonly fitted alongside windlass or capstan assemblies on cargo and tanker vessels.

Spurling Pipe with Cover
For chain 46-97mm · Deck Hardware · Covered spurling pipe
Type
spurling_pipe
Chain range (mm)
46-97
Common Failures & Inspection Points
  • Cover gasket deterioration
  • Hinge pin seizure
  • Internal corrosion
Service: Replace gasket when leaking; grease hinge pin monthly.
Spare Parts: Ersatzteile über Generic (Class Approved) oder zugelassene Vertriebspartner. Lead time: 2-6 Wochen.
Strengths
  • Hinged cover provides easy access for inspection and maintenance
  • Gasket seal reduces water entry and corrosion of internal components
  • Accommodates a wide chain size range (46‑97 mm) with a single fitting
  • Class‑approved design meets standard classification society requirements
Weaknesses
  • Cover gasket can deteriorate over time, leading to leaks if not replaced promptly
  • Hinge pin may seize without regular greasing, impairing cover operation
  • Internal corrosion possible if water ingress occurs or maintenance is neglected
  • Limited to the specified chain size range; larger chains require a different fitting
Typical Vessels: Bulk carrierTankerContainer shipOffshore supply vesselGeneral cargo vessel
Decision Guide: Choose if you need a reliable, class‑approved chain guide that protects the chain and deck opening from water ingress and can handle 46–97 mm chains. Avoid if regular maintenance (gasket replacement, hinge greasing) cannot be assured or if larger chain sizes are required.
Use Cases: Commonly installed on deck winches for mooring lines, cargo handling gear, and anchor chain guides where a sealed passage is desirable to prevent water entry into the deck cavity.

  • Complexity of the Panama guide can increase downtime if not serviced correctly
Typical Vessels: TankerBulk CarrierContainer ShipOffshore Supply VesselAnchor Handling Tug Supply (AHTS)
Certifications: DNV GL Class ApprovalABS Approved
Decision Guide: Choose if: the vessel operates in explosive‑gas zones, requires a durable chain guide with integrated Panama system, and values long‑term wear resistance. Avoid if: budget constraints are critical, the ship does not need Ex protection, or deck reinforcement is impractical.
Use Cases: Installed on the main deck of tankers, bulk carriers and offshore supply vessels to guide anchor chain during mooring and anchoring operations, especially where gas‑laden cargoes or fuel vapours create a hazardous atmosphere.

Strengths
  • Robust forged steel construction with enhanced fatigue resistance
  • Modular design allows quick replacement of worn sections
  • Integrated wear‑monitoring points reduce unscheduled downtime
  • DNV‑approved for high‑load anchoring applications
  • Compatible with Kongsberg’s remote monitoring and control suite
Weaknesses
  • Higher initial procurement cost compared with standard chain pipes
  • Requires specialized torque tools for bolt tightening during maintenance
  • Weight may increase overall deck load, affecting stability calculations on smaller vessels
  • Limited aftermarket spare‑part availability outside Kongsberg network
Typical Vessels: Crude oil tankersBulk carriersContainer ships with high‑capacity mooring systemsOffshore supply vesselsLNG carriers
Certifications: DNV
Decision Guide: Choose if: you need a proven, high‑strength chain pipe for heavy anchoring or towing loads and want integrated wear monitoring to extend inspection intervals. Avoid if: budget constraints dominate or the vessel’s deck load capacity is marginal, making lighter standard fittings preferable.
Use Cases: The M50 & M100 are typically installed on vessels that perform frequent heavy‑anchor deployments, such as tankers loading/offloading at offshore terminals, bulk carriers operating in high‑wave regions, and offshore supply ships handling large mooring lines for rigs. They are also favored where remote condition monitoring is part of the ship’s asset management strategy.

Service: Klüsen-Kantenprüfung bei Dockung. Poller-Fundamentbolzen Drehmoment jährlich. Panama-Führung Messung bei Dockung.
Spare Parts: Ersatzteile über MacGregor Finland Oy oder zugelassene Vertriebspartner. Lead time: 2-6 Wochen.
Strengths
  • Robust load rating suitable for heavy‑weight mooring chains on large vessels
  • Twist‑lock operation allows fast and secure engagement/disengagement
  • Corrosion‑resistant coating (typically zinc or epoxy) reduces maintenance intervals
  • Designed to integrate with MacGregor deck hardware families, simplifying installation
Weaknesses
  • Edge wear of the locking jaws reported in service (Klüse Kantenverschleiß)
  • Foundation bolts may loosen over time and require periodic torque checks
  • Panama‑type guide wear can affect smooth operation if not inspected regularly
  • Relatively high initial cost compared with basic bolted chain pipe fittings
Typical Vessels: Container shipBulk carrierTankerRo‑Ro vesselOffshore supply vessel
Decision Guide: Choose if: you need a high‑capacity, quick‑acting mooring connection on vessels that already use MacGregor deck systems and can commit to regular inspection of lock edges and foundation bolts. Avoid if: budget constraints are tight, or the vessel operates in environments where frequent edge wear cannot be readily monitored.
Use Cases: Commonly installed at bow and stern mooring points for line handling during port entry/exit, as well as on deck rails for spurling pipe deployment on offshore supply ships. The twist‑lock design is favored where rapid line changes are required, such as in high‑traffic ports or during emergency anchorage operations.
