Heavy Lift Engineering & Lift Planning

Maas maritime consultancy b.v.

Precision-driven engineering for the world’s heaviest assets. We provide technical oversight, lift plan verification, and on-site supervision to ensure that every heavy lift operation in the ARA region is executed with zero compromise on safety.

Heavy Lift Engineering Excellence

Managing the physics of movement for critical maritime assets.

Handling ultra-heavy cargo requires a level of precision that goes far beyond standard stevedoring. Our technical experts specialize in the oversight of heavy lift operations, providing the engineering support and on-site attendance necessary for even the most demanding industrial loads. Whether utilizing specialized shore cranes or a vessel’s own heavy-lift gear, our team ensures that every movement is calculated, controlled, and compliant.


We focus on the critical interface between the cargo, the lifting equipment, and the vessel’s stability. Our independent specialists provide the peace of mind that comes from knowing a dedicated professional is monitoring every shackle, sling, and ballast adjustment.

What is included in a professional lift plan verification?

A comprehensive verification involves reviewing rigging diagrams, crane load charts, and ground bearing pressure calculations. In ports like Rotterdam and Antwerp, we ensure that the proposed methods meet both local terminal requirements and international safety standards.

What are the primary risks involved in a 3,000-ton heavy lift operation?

The most significant risks include sudden changes in vessel stability, structural failure of lifting points, and dynamic loading caused by wind or swell. Our experts mitigate these risks by performing rigorous stability calculations and verifying that all lifting gear is certified for the specific dynamic forces encountered during the operation.

When is a tandem lift required, and how is it supervised?

A tandem lift is used when a single crane's capacity or outreach is insufficient for the load. Our lead surveyors provide the critical coordination needed between crane operators, ensuring that the load remains balanced and that neither crane exceeds its individual safe operating window during the synchronized movement.

What role does weather play in heavy lift safety in Dutch and Belgian ports?

Wind speed and visibility are critical. Our team monitors real-time weather data in ports like Rotterdam and Antwerp to determine the "safe window" for a lift. If wind speeds exceed the crane’s or cargo’s aerodynamic limits, we have the authority to halt the operation until conditions are safe.

Can you help with lashing and securing after the lift is completed?

Yes. Once the heavy lift item is safely on board, it must be secured for ocean transit. We often combine this with our Lashing, Securing & Stowage services to provide a seamless transition from lifting to transport.
