Today’s ship maintenance sector demands ever faster action and high standards of dimensional accuracy. Reducing vessel downtime and optimising operating costs are no longer merely competitive advantages, but fundamental requirements for ensuring efficiency, meeting operational schedules and keeping the fleet operational.
From 1 to 4 September 2026, Elsa Srl will be exhibiting at SMM in Hamburg, the world’s leading trade fair for the maritime industry. At our stand (Hall B7, Stand 142), shipowners, fleet managers and technical managers can discover the range of portable Supercombinata line boring machines, which have been entirely developed and manufactured in Italy to carry out inline boring, overlay welding and mechanical machining directly on board or in the shipyard.
The advantages of mobile line boring machines in the shipping sector
Maintenance in the shipping sector presents particular challenges: critical components such as the propeller shaft bearings, the rudder propeller, the main engine bearings and the mooring systems are subject to severe wear and tear due to salt corrosion and constant mechanical stress. Transporting these large components to a workshop on land involves high logistical costs and can significantly prolong the downtime of the ship or vessel.
The portable Supercombinata line boring machines make it possible to overcome these challenges, as mechanical machining can be carried out directly on site, on board the ship or at the shipyard. The key benefits include:
- Reduced downtime: Tolerances can be restored directly on board, significantly reducing the time required for repairs;
- High precision in on-site machining: Precise alignment and high-quality surface finishing guarantee results that meet the high standards of the marine industry;
- Reduction in logistics costs: Machining directly on site avoids complex handling operations, transport and the handling of heavy or oversized components.
The compact solution: performance in extremely confined spaces
When carrying out maintenance work on board, particularly in engine rooms or in areas with limited space, the availability of working space presents one of the greatest challenges. In such situations, compact machines are required that can be used without the need for time-consuming dismantling of components or surrounding machinery.
Elsa Srl’s response to this requirement is the Supercombinata EASY COMPACT, one of the solutions to be unveiled at SMM Hamburg 2026. This portable drilling machine has been specifically developed for use in locations where conventional machines have limited access due to their dimensions, as it features very compact dimensions in both the longitudinal and radial directions.
Despite its compact design, the Easy Compact retains the characteristics typical of the Supercombinata series, such as performance, precision and stability. With a machining range from Ø 42 mm to Ø 250 mm, it enables line boring work to be carried out directly on site, thereby reducing the logistical constraints typical of shipyards.
Operational flexibility: high machining capacity
For sites where different machining operations are carried out daily on various diameters, adaptability is crucial for handling complex applications and being able to react quickly to unforeseen events on board. The versatility of the equipment thus becomes a strategic factor in increasing the efficiency of maintenance work.
The Supercombinata SC3, one of the solutions presented by Elsa Srl at SMM Hamburg 2026, is a concrete response to the requirements of those who need high operational capacity and maximum reliability in mechanical machining.
The SC3 enables an extremely wide range of diameters to be covered and complex machining operations to be carried out, from internal and external line boring to threading and drilling. The system’s high cutting performance and stability during machining ensure accuracy and precision even with large diameters, making the machine ideally suited to demanding applications in shipbuilding.
More than just line boring: solutions for expanding on-site machining capabilities
The versatility of Elsa’s solutions is not limited to line boring: thanks to extra kits and accessories, the machines’ range of applications can be expanded, enabling further machining steps to be carried out directly on site. At SMM Hamburg 2026, a number of solutions will be presented that are designed to boost the efficiency and productivity of maintenance work.
- EFK – electronic facing kit: the digital evolution of flange facing with a machining range from Ø 55 mm to Ø 615 mm. The system allows the cutting parameters to be controlled via an electronic control unit, which regulates the feed rate independently of the rotational speed and ensures a high surface finish.
- Facing kit: A special system for facing on orthogonal planes and for producing seats for O-rings and Seeger rings with a machining range from Ø 48 mm to Ø 800 mm.

Frequently Asked Questions (FAQ)
Q: What types of machining operations can be carried out with the Supercombinata line borig machines on board a ship?
A: Our mobile machines can be used for inline boring jobs, internal and external overlay welding, threading, boring and facing of orthogonal surfaces. They are ideal for the repair of bearing seats on the propeller shaft, rudder shaft, engine bearings, etc.
Q: Will the Supercombinata line boring machine be on demonstration at SMM Hamburg 2026?
A: Yes, the Supercombinata EASY COMPACT and SC3 models will be shown in Hall B7 (Stand 142). Our technicians will be on hand to give practical demonstrations of the machines and accessories, such as the EFK electronic facing kit.
Q: How can I arrange an appointment with the Elsa team during the trade fair?
A: To avoid waiting times and to arrange a personalised consultation, you can fill in the contact form on this website or send an email to commerciale@elsasrl.com.
Q: Which portable Supercombinata line boring machine is best suited for working in extremely confined spaces?
A: For use in environments with limited space and restricted access, the benchmark model with a Ø 40 mm boring shaft is the Supercombinata EASY COMPACT. Thanks to its ultra-compact design, it reduces the space required to a minimum whilst ensuring a standard machining capacity ranging from Ø 42 mm to Ø 250 mm.
Note: If space permits and different diameters need to be machined, other models from the Supercombinata series may also be selected.
