Shipping a Tunnel Boring Machine (TBM) from/to the UK

Pre-shipment Planning: A Strategic Imperative

The successful international shipment of a Tunnel Boring Machine (TBM) demands meticulous planning and precise execution. Overlooking critical details can lead to significant delays, increased costs, and potential damage to the equipment.

TBM Dimensions and Weight Assessment

Accurate determination of the TBM's dimensions and weight is paramount. This data dictates vessel selection, securing methodologies, and overall logistical strategy. Inaccurate information can result in the selection of unsuitable vessels or inadequate securing arrangements, potentially jeopardising the entire operation.

Disassembly Strategy Evaluation

Evaluate the feasibility and cost-effectiveness of partial TBM disassembly. If disassembly is deemed advantageous, meticulously document the entire process, including detailed schematics and component inventories. This documentation is crucial for efficient reassembly at the destination site.

Port Selection Criteria

Identify suitable ports equipped with heavy-lift capabilities and ample space for handling out-of-gauge (OOG) cargo. Consider the port's proximity to both the origin and destination project sites to minimise inland transportation costs and time. Evaluate port infrastructure, including crane capacity, quay strength, and storage facilities.

Vessel Selection Protocol

Select a heavy-lift vessel specifically designed to accommodate the TBM's dimensions and weight. Factor in transit time, fuel consumption, and associated costs. Consider the vessel's track record, insurance coverage, and compliance with international maritime regulations.

Permits, Licenses, and Customs Compliance

Secure all necessary export/import permits, customs documentation, and special licenses required for OOG cargo transport. Address customs duties, tariffs, and potential import/export restrictions specific to TBMs well in advance. Non-compliance with customs regulations can result in significant fines, delays, and even cargo seizure.

Cargo Insurance Procurement

Obtain comprehensive cargo insurance to protect against potential damage or loss during transit. Ensure the insurance policy covers all aspects of the shipment, including loading, unloading, sea freight, and inland transportation. Review the policy terms and conditions carefully to understand the coverage limits and exclusions.

Handling Plan Development

Develop a detailed handling plan encompassing lifting procedures, securing methods, and transportation logistics from the factory/site to the port and from the port to the final destination. Incorporate diagrams, specifications, and risk assessments. The handling plan should be reviewed and approved by all stakeholders, including heavy-lift contractors, port authorities, and the vessel's captain.

Heavy-Lift Contractor Selection

Engage experienced heavy-lift contractors with a proven track record in handling OOG cargo. Verify their certifications, insurance coverage, and safety protocols. Conduct thorough site inspections to assess their capabilities and equipment.

Transportation to Port: Inland Logistics

Specialised Transport Arrangements

Utilise heavy-duty trailers or other specialised transport equipment specifically designed for OOG cargo. Ensure the transport equipment is properly maintained and inspected to prevent breakdowns or accidents.

Route Planning and Optimisation

Plan the transport route meticulously, considering weight restrictions, bridge clearances, overhead power lines, and other potential obstacles. Obtain all necessary permits for oversized loads from relevant authorities. Conduct route surveys to identify and mitigate potential risks.

Escort Vehicle Deployment

Employ escort vehicles to ensure the safe and efficient transportation of the TBM. Escort vehicles provide traffic control, warning signals, and communication support. They also help to minimise disruption to other road users.

Loading and Securing Operations

Heavy-Lift Equipment Utilisation

Employ cranes and other heavy-lift equipment with sufficient capacity to safely handle the TBM's weight. Ensure all lifting equipment is certified and operated by qualified personnel. Conduct pre-lift inspections to verify the equipment's integrity.

Securing System Implementation

Implement a robust lashing system to securely fasten the TBM to the vessel's deck, preventing movement during transit. The securing plan must be approved by the vessel's captain and port authorities. Use certified lashing materials and follow established securing procedures.

Weather Condition Monitoring

Continuously monitor weather conditions and postpone loading operations if adverse weather is anticipated. High winds, heavy rain, or rough seas can compromise the safety of the loading operation and potentially damage the TBM.

Sea Freight Management

Voyage Monitoring and Tracking

Track the vessel's progress throughout the voyage using satellite tracking systems. Monitor weather conditions along the route and adjust the voyage plan as necessary.

Communication Protocols

Maintain regular communication with the shipping line, heavy-lift contractors, and other stakeholders. Provide timely updates on the vessel's progress and any potential delays.

Unloading and Transportation to Site: Destination Logistics

Unloading Procedures

Exercise the same level of care and precision during unloading as during loading. Use the same heavy-lift equipment and securing methods. Conduct post-unloading inspections to identify any damage that may have occurred during transit.

On-Site Transportation Arrangements

Arrange specialised transport to move the TBM from the port to the project site. Coordinate with local authorities to obtain necessary permits and approvals.

Reassembly Process (if applicable)

Reassembly Execution

Carefully reassemble the TBM according to the pre-determined plan. Use qualified technicians and follow established reassembly procedures. Conduct thorough testing to ensure the TBM is functioning correctly before putting it into operation.

Critical Considerations for TBM Shipping

Cost Management

OOG shipments are inherently expensive. Develop a detailed budget that accounts for all potential costs, including transportation, handling, permits, insurance, and customs duties. Seek competitive quotes from multiple service providers.

Time Allocation

Allocate ample time for planning, transportation, and handling. Unexpected delays can occur due to weather, customs inspections, or equipment breakdowns. Build contingency time into the schedule to mitigate the impact of potential delays.

Risk Mitigation

Develop a comprehensive risk management plan to identify and mitigate potential problems. The plan should address potential risks related to transportation, handling, weather, customs, and security.

Environmental Stewardship

Adhere to all environmental regulations concerning fuel efficiency, emissions, and the potential for spills during transport. Develop a plan to minimise environmental impact. Use environmentally friendly transportation methods and equipment whenever possible.

Emergency Response Planning

Establish clear emergency procedures for accidents or delays, including contact information for relevant authorities (e.g., coast guard, port authorities, emergency services). Conduct regular drills to ensure that personnel are familiar with the emergency procedures.

Customs and Duty Compliance

Thoroughly research and understand all customs duties, tariffs, and import/export restrictions specific to TBMs for your chosen route. Ensure all necessary documentation is prepared well in advance and submitted to the relevant authorities.
