Project Overview

When the 192-meter bulk carrier "Mineral Dragon" suffered a catastrophic anchor and chain loss in the Istanbul anchorage area, Seaway Ship Services was immediately mobilized to execute one of the most technically demanding at-sea recovery and installation operations in recent maritime history. With a vessel displacement exceeding 178,000 deadweight tonnes positioned in open water, this project demanded extraordinary expertise in heavy-lift marine operations, precision engineering and seamless coordination across multiple specialized teams.

The challenge was formidable: retrieve massive multi-ton anchoring equipment from quayside storage, transport it across busy shipping lanes, position alongside an anchored vessel in active seas and execute flawless installation of the port side anchor and complete chain assemblyβ€”all without drydocking or towing the vessel to port. Operating in one of the world's busiest maritime corridors, our team faced the added complexity of coordinating with port authorities, managing vessel traffic and accounting for tidal movements and weather windows.

This project showcased Seaway's unparalleled capabilities in complex marine engineering. Our specialized crew coordinated heavy-lift crane operations, tugboat positioning, diving support teams and windlass system integration to deliver a complete anchoring system restoration. The successful at-sea installation eliminated weeks of costly vessel downtime and demonstrated why Seaway is recognized as Turkey's premier provider of emergency maritime solutions for critical vessel systems.

The Challenge

The vessel had lost its port anchor and complete chain system while at anchor in the Istanbul roadsβ€”a critical safety equipment failure that prevented the vessel from safe anchoring operations. Traditional solutions would require expensive drydocking or port entry, resulting in significant operational delays and commercial losses.

The operation required transporting multi-ton anchor and chain assemblies from shore, positioning them accurately alongside a moving vessel in open water, coordinating heavy-lift crane operations with tug positioning and installing the complete system through the hawse pipe while managing load dynamics, weather conditions and vessel movements in busy shipping lanes.

Our Solution

Seaway deployed a comprehensive at-sea installation capability combining specialized transport vessels, heavy-lift mobile cranes, professional diving teams and expert marine riggers. We executed detailed lift planning, load analysis and weather window forecasting to ensure safe operations throughout the multi-phase installation process.

Our team coordinated synchronized operations between shore facilities, transport barges, positioning tugs and the vessel's deck crew. Using precision rigging techniques and certified heavy-lift equipment, we successfully installed the complete port anchor and chain assembly directly at the anchorage, restoring full operational capability without vessel movement to port facilities.

Execution Process

Phase 1: Emergency Response & Equipment Procurement

Immediate mobilization following vessel's distress call. Sourcing of class-approved replacement anchor and certified grade chain suitable for 178,000 DWT bulk carrier operations. Coordination with classification society for equipment approval and installation oversight. Preparation of specialized transport and heavy-lift equipment including mobile cranes, rigging gear and positioning tugs.

Phase 2: Shore-Side Preparation & Load-Out

Comprehensive inspection and certification of replacement anchor and chain system. Preparation of lifting arrangements and seafastening for marine transport. Heavy-lift crane operations to load multi-ton anchor assembly onto specialized transport vehicle. Securing of chain assemblies for safe maritime transit. Pre-positioning of all installation equipment at departure quay.

Phase 3: Marine Transportation to Anchorage

Deployment of heavy-lift barge and positioning tugs for equipment transport to vessel location. Navigation through Istanbul shipping lanes to anchorage area while maintaining coordination with vessel traffic services. Approach and positioning alongside anchored bulk carrier using precision tugboat maneuvering. Establishment of stable working platform between transport barge and vessel's side.

Phase 4: Heavy-Lift Operations & Anchor Installation

Deployment of mobile heavy-lift crane for anchor and chain handling operations. Precision lifting of multi-ton anchor assembly using certified rigging and slings. Careful positioning of anchor at vessel's port hawse pipe. Installation of connecting hardware including shackles and swivels with torque specifications. Integration of first chain lengths and connection to anchor crown.

Phase 5: Chain Installation & Windlass Integration

Systematic feeding of chain sections through hawse pipe and into chain locker. Precise measurement and marking of chain shots for operational reference. Connection of chain assembly to vessel's windlass system with proper end shackles. Load testing of complete installation under controlled conditions. Verification of windlass operation for chain deployment and retrieval.

Phase 6: Testing, Certification & Handover

Comprehensive operational testing of complete anchoring system including windlass function verification, chain brake testing and anchor deployment trials. Classification society survey and certification of installation. Documentation of all work performed including lifting records, torque values and test results. Final handover to vessel with complete operational manual and maintenance recommendations. Vessel cleared for normal anchoring operations.
