N 961 – Cable Layer

The crane pedestal is an essential element in the operation of the ship-mounted crane. This pedestal is a pillar, which serves as a rotation axis and support for the crane arm.

Here are some key aspects of a crane pedestal:

  1. Structural Support: The pedestal provides support and stability for the crane arm and associated mechanisms, allowing for safe lifting and handling of loads.
  2. Mobility: This pedestal allows the crane arm to pivot or rotate, offering flexibility and the ability to maneuver loads in various directions and positions.

 

Challenges:

Installing the crane pedestal on a ship is a complex and difficult process, requiring attention to detail and advanced technical skills.

- Flatness: It is essential that the base of the pedestal be perfectly flat to ensure stability and proper operation of the crane. Deviations here are a maximum of 0.15 degrees.

- Verticality: The pedestal must be mounted perfectly vertically to allow for proper rotation and operation of the crane. Deviations here are on the order of microns. A micron is 1,000 times smaller than a millimeter.

- Welding: Welding the crane pedestal is another critical aspect. This operation must be performed by elite welders. The entire weld is NDT controlled. A poor weld can lead to the displacement or even the collapse of the crane pedestal, which could cause significant damage to the ship. This could affect both the structure of the ship and its functionality.

 

Was it difficult? Yes! It was all about expertise and extreme precision. The result: the work was delivered to the client flawlessly, without any remarks.

At Minerva Navis, every job becomes a worry-free experience for our clients. They can confidently monitor the progress, knowing that their work is in safe hands and will be successfully completed.

A ship's mast is an essential technology hub, being equipped with advanced functionality including communication systems, GPS, navigation lights, sound warning and lighting, all of which contribute to the efficiency and safety of sea travel. Therefore, the mast ensures the precise and safe navigation of the ship, being a crucial pillar in the management of maritime operations.

Each mast is designed to meet the specifications and needs of the vessel it serves, thus becoming a unique and customized construction that contributes to the vessel's identity and functional efficiency.

 

Challenges:

The construction of this mast involved significant difficulties, especially highlighted by the need to work with a variety of rays, angles, and inclinations.The elements of the work had to be adjusted with extreme precision during the construction phase, to ensure that the final structure is not only aesthetically pleasing, but also functional and durable. Getting this job right requires skill and experience, as each element influences how the mast will interact with external forces such as wind or tension from mounted equipment.

At the same time, the mast has an impact on the balance and stability of the vessel, as changes in the design or weight of the mast can significantly influence the center of gravity of the vessel. A wrong execution of the work could adversely affect the maneuverability and safety of the vessel, increasing the risk of capsizing or difficulties in navigation.

These details make mast construction a painstaking and highly specialized task.

 

Minerva Navis demonstrated an outstanding performance in the execution of this complex work, managing to complete the project on time and hand it over without objections. Our top foremen, including skilled fitters and welders, have outdone themselves in making this impressive structure.

The contribution of our grinders was no less important; they perfected the work cosmetically, ensuring that every detail is finished with the utmost care. This achievement underscores Minerva Navis's commitment to excellence and quality, reinforcing its reputation as a leader in the shipbuilding industry.

N961 – Cable layer

Strategically placed at the front of the ship, the bulb shapes the course of the water, cleaving the waves with a special grace. This master of hydrodynamics reduces the force with which water opposes the ship's forward motion, thereby saving precious fuel. This technological solution allows an increase in the speed of travel by about 7-10%, thus reducing the operating costs of the vessel.

In rough waters, it becomes a reliable ally, giving the ship impressive stability, minimizing rocking and improving maneuverability.

 

Challenges:

In the assembly phase, it was key to create and preserve an impeccable flatness of the structure, the section being built on the transversal wall at the stern. Due to the significant height, every millimeter counted; any deviation from perfect flatness could have created a domino effect, disrupting the verticality of the central member and, by extension, compromising the precise alignment of the entire assembly of transverse and longitudinal members.

 

A major challenge was the installation of the outer cladding sheets, of different thicknesses and with double curvature, where our elite foremen, together with our experienced fitters, displayed exceptional technical mastery and accuracy, demonstrating extraordinary skill.

 

Our top welders were also put to a remarkable challenge due to the extremely confined spaces they had to work in, as well as the considerable volume of welding checked using NDT (Non-Destructive Testing) techniques.

 

In an amazing display of efficiency, the section was erected without delay, even in the midst of strong wind and torrential rain in a surprisingly short time and with remarkable accuracy, meeting the client's deadline.

 

Minerva Navis triumphed in the face of this exceptional challenge, successfully completing the work within the deadline set by the site. Our success was remarkable, considering the complexity and difficulty of the operations carried out. Moreover, the work was accepted without any comments by both the Certification Class and the client. This not only confirms our technical competence, but also our commitment to deliver high quality results in shipbuilding. Minerva Navis remains true to its value of excellence.

Active contribution

Imagine a world where the wind doesn't just blow, it powers our cities, communities and hearts. At Minerva Navis, we don't just dream of this future, we build it!

We support the global ambition of zero emissions by 2050, actively contributing by building offshore structures for offshore wind farms for our client Chantiers de l'Atlantique in France.

Our offshore structures are more than just buildings: each one provides green energy for 800,000 people. Minerva Navis, carried out prefabrication, assembly and mounting with special attention to quality, the requirements for these platforms being extremely high. They must withstand the forces of the sea and vibrations, which requires top quality materials and welds.

 

Challenges:

Requirements for impeccable welding. Every weld has been executed and checked with the utmost attention, because the resistance depends on it. With 50% of welds controlled by U.T. and with large extensions to the smallest defect found, we left no room for error.

Execution of the construction without affecting the sheet metal field. Special metal plates of the highest quality were used. The surfaces were prepared with the greatest care and for large thicknesses, over 30 mm, preheating was done. The use of the hammer was prohibited. The sheet metal fields were tested with M.T..

 

We proudly delegated an elite team for these operations, who not only delivered brilliantly, but were also appreciated, receiving direct praise from the client. Coordination was masterfully orchestrated by our seconded engineer and foremen.

Our welders shined, exceeding expectations with a formidable 97% pass rate in welding tests. And our fitters, masters of precision, have perfectly combined quality with speed, consolidating the reputation of excellence we have in the field.

Project completed by Minerva Navis: Assembly of the thruster tunnel section

The thruster tunnel helps the 360 degree maneuver of the ship.

This propulsion system is in the bow of the ship and helps with better maneuverability. The system facilitates docking, because ity allows the captain to turn the ship to port or starboard without using the main propulsion mechanism.

 

Challenges:

The biggest challenge was when connecting the 67 ton section with the 47 ton thruster tunnel, so that at the end there would be a flatness deviation of ±1 mm.

The complexity of the section is given by the thickness of the plates, plus the intersections between the longitudinal and transversal sections.

For this work, we had 80 lm of US controlled welding and 100 lm of controlled welding with penetrating liquids and magnetic powder.

 

Minerva Navis successfully completed this job, at the deadline required by the shipyard and at a superior quality. The client accepted the work from the first visit, without observations.
