Equipment maintenance professionals increasingly participate in the strategic decisions of companies, as the preservation of assets is one of the success factors for operational activities of any kind. Investing in machines costs a lot of money and keeping them operating in good condition, too. When stopped, then, they become an endless source of waste and loss. It is for this reason that companies have rightly decided to structure the maintenance area of their businesses.

Klabin's Forestry Business followed this trend, disassociated maintenance from the operational areas and created the Forestry Maintenance Management, which currently has an approximate assets of 380 pieces of equipment, 23 brands, 90 different models, 90 heads, 230 implements and, on average, , more than 20 thousand preventive orders per year. This allowed, together with the operation, to maintain the reliability of the equipment at adequate costs.

1. Remote Maintenance:
Due to the expansion of the industry, there was a natural increase in the supply of wood of both types (Pinus and Eucalyptus ) at Klabin, from 3.5 millimeters per ton to 16 millimeters per ton over a period of 10 years. This increment required the search for wood in an average radius above what we usually operated, expanding from the south of São Paulo to the north of Santa Catarina.

The moment for this change occurred with the entry into operation of the Puma Unit, as well as its expansion, called Project Puma 2, distancing the Operating Modules from our base, which gave us agility in assisting these fronts, whether they be Harvest, Biomass, Logistics or Forestry. Where there is any equipment operating, if necessary, we have to arrive quickly with technical assistance and parts. On the other hand, equipment with increasingly advanced technologies requires specialized and well-trained labor.

Thus, to improve our service, we created a Maintenance Training Center, which trains professionals, in addition to providing basic training, provided for in our legislation. In order to speed up the service for these professionals and quickly reach the most remote operations, the idea was born of opening the Remote Maintenance Center, at our base, where Klabin's Forestry Maintenance is located, in addition to the Central Workshop, Maintenance Engineering, Central Warehouse and Maintenance Training Center.

The fundamental function of the Remote Maintenance Center is to support operators and mechanics who have a faulty machine that the field teams are unable to resolve, receiving remote support via the Audible Response Unit. This procedure allows employees to interact with the automated service system through a telephone call (0800).

In addition to the Audible Response Unit , the Remote Center uses WhatsApp , phone calls, email and video calls as tools to facilitate communication.

There are important benefits that this service brings to Florestal, the main ones being the following:

Increases equipment availability by minimizing machine maintenance time, ensuring greater availability in the field;

Provides faster technical support to on-site mechanics and technicians, thereby resolving the issue more efficiently;

It reduces costs with remote assistance, making it possible to solve problems without the need for technicians to travel, since we have modules in several cities in the interior of Paraná and São Paulo.

The idea of creating a center to meet these demands arose when the Maintenance team saw the need to centralize technical assistance and make it more agile. In some situations, the mechanic is in the field and cannot solve a machine problem alone. That's when we offer assistance. When contacting us, we check what the problem is, whether it is a missing part, whether the mechanic is unable to carry out the repair alone or is unable to carry out an analysis of the equipment.

2. Use of technology from HoloLens glasses:
The HoloLens is a glasses technology that uses mixed and augmented reality. This tool performs a real-time diagnosis, bringing us enormous gains in the agility and quality of maintenance, in addition to improvements in connectivity and constant training in the use of technologies. This demanded sudden changes in the acceptance of the people who have used this tool.

In tests using the tool, we set up a scenario with high investment, first in equipment resources, then in training people, leaving the tool safe and the environment controlled.

HoloLens requires massive bandwidth due to its high resolution of images and videos, this makes the challenge even greater in the forestry world, where connectivity is low and access is very restricted, leaving remote assistance with a choice of input. in this field of work.

In tests carried out, we use a remote center with monitors and televisions, through which the specialist technician is available for manual and procedure resources, in addition to field experience. This technician must be adapted to field maintenance and have a very effective technical communication, guaranteeing reliability in the information and making the process viable.

The field technician in possession of the glasses , activates via the Teams call the specialist in the remote center , from where he has real-time access to the images that the technician is producing in the field, being able to interact verbally, with arrows and circles. This makes it possible to send digital procedures, work instructions and directly assists in maintenance even miles away.

For the use of so many files and for a more assertive use of HoloLens technology , there is a need for high resolution internet in the field. To overcome this, we carried out several tests and were more successful with Starlink 's internet , with which we achieved satisfactory results, with real-time interaction and no crashes or delays.

For final tests, we carried out interventions between countries: Brazil in possession of the glasses and Canada (the equipment manufacturer) in the computer, as if it were the remote center; there were also interventions between the states of Paraná and Santa Catarina, which made us sure that the use of HoloLens would benefit us.

At Klabin, we always seek to make everyone's work more efficient and agile. And these two innovations are a great example of our team's dedication.
