When the Anchor Won’t Budge: Lessons from a Windlass Breakdown at Anchorage

 ⚙️ “When the Anchor Won’t Budge: Lessons from a Windlass Breakdown at Anchorage”

❓ Three Quick Questions for You

• Has your vessel ever experienced difficulty heaving up anchor under charter party terms?
• Do you have an emergency maintenance protocol when equipment fails at anchorage?
• Are your crew and shore team aligned on reporting, repair logs, and charterer communication?

If you answered yes, no, or unsure to any of the above, this post is your anchor ⚓ of insight!

 

📜 Clause Spotlight: Maintenance Obligations Under Charter Party

⚠️ Charter Party Context:

While this blog isn't based on one specific clause, the events are related to charterers’ instructions, vessel readiness, and owner’s obligation to maintain equipment in efficient working order under a time charter party.

Relevant clause example (NYPE format):

“The Owners shall maintain the vessel and her machinery in a thoroughly efficient state throughout the currency of this charter.”

🧐 What Happened?

A vessel at Honiara Anchorage received sailing instructions. While heaving up the starboard anchor, the windlass failed to lift it despite the anchor hanging vertically with 4 shackles.

Suspecting a deep embedment in the seabed or a mechanical failure, the crew maneuvered slightly to test anchor freedom — confirming the anchor was not stuck.

🔍 Root Cause & Action Taken:

• Initial Diagnosis: Anchor was not embedded; suspect hydraulic system issue.
• Observations:
• Hydraulic oil overheated
• Coolers and filters found clogged with dirt
• Oil low in viscosity (heat-affected)
• Action:
• Cleaned and serviced filters & cooler units
• Drained 150L old oil, replaced with fresh oil
• System purged, tested on no-load
• Final Result: Anchor lifted smoothly with 2 pumps

 

🚫 Common Pitfalls

• Ignoring Heat Symptoms: Elevated oil temperature = early warning
• Skipping Preventive Checks: Coolers and filters often neglected in humid/tropical anchorages
• Inadequate Oil Quality Monitoring: Viscosity checks often skipped unless failure occurs
• Inconsistent Communication with Charterers: Delayed updates can escalate issues under time charter

 

📌 Practical Tips for Operators & Managers

• ✅ Include windlass system checks in anchorage readiness drills
• ✅ Maintain records of hydraulic oil changes, filter cleaning logs
• ✅ Invest in inline temperature sensors for critical hydraulics
• ✅ Ensure crew is trained to troubleshoot hydraulics under pressure
• ✅ Always document and report technical failures transparently to Charterers

 

🧑‍⚖️ Legal & Charter Party Implications

• Under time charter, owners bear the burden of maintaining operational readiness.
• Delay caused by windlass breakdown, if not communicated promptly or resolved efficiently, could lead to hire dispute or off-hire claim.
• BIMCO Commentary highlights the importance of maintaining “efficiency” not just in propulsion, but all deck machinery essential for safe navigation and port operations.

 

✅ Actionable Steps for All Stakeholders

👨‍✈️ Owners & Technical Managers:

• Schedule preventive maintenance on all hydraulic deck machinery
• Keep critical spares and cleaning tools for coolers onboard
• Educate crew with troubleshooting flowcharts

📞 Charterers:

• Ensure your ops team clearly communicates instructions
• Allow reasonable time for mechanical rectification when justified

🚢 Ship Operators:

• Update your vessel status reporting SOPs
• Include breakdown logs in the next Noon or Voyage Report

 

📣 Conclusion & Call to Action

Technical failures can occur anytime — but how you detect, react, and report them determines your professional credibility and charter party performance. This case is a reminder that attention to detail wins respect — from both charterers and crewmates alike.

🧭 Stay smart. Stay ready. Stay respected.
