Abstract: The concern of industries around the world with the environment is long-standing, and
in recent years the acronym ESG - Environmental, Social and Governance, has gained
more and more space in organizations. Faced with this new variable, the development
and execution of preventive actions have increased and new controls are being
required for better company management. The objective of this work was to evaluate
the silting process that occurs in the basins and settling ponds of the Ponta da Madeira
Maritime Terminal, through bathymetric surveys. For the study, bathymetric data
provided by VALE S/A was used, seeking to understand the behavior of silting in
different periods and the treatment carried out by the company to manage this problem.
The bathymetric surveys were carried out using an autonomous boat and processed
using Hypack software, license nº 04B8857917004341. The results showed that with
control of the basins, via bathymetry and effective dredging, the levels of the basins
were stable, with no occurrences of overflow or spillages for the community of Fumacê
and for the São Marcos Estuarine Complex – CESM, in the case of spills to CESM, the
water would meet all parameters within current environmental standards, CONAMA
430. We can conclude that the management of basins with bathymetry, dredging and
environmental control regarding water quality is effectively guaranteeing compliance
with the ESG rules required of organizations.

Abstract: Located at the Ponta da Madeira Maritime Terminal, Pier 4 has one of the most modern
ship mooring systems. This is necessary due to the strong currents and the wide
variation in local tides. Developed to keep ships attracted and safe during their
operations, this system combines onboard moorings, cables that leave the ship to land,
and shore moorings, winches from which cables are sent from land to board. This
material deals with issues related to tension loads applied to ships' cables, focusing on
monitoring and controlling moorings and comparing this with specific operational
procedures. The study aims to analyze and quantify these expenses during the stay of
ships at Pier 4 of the TMPM, improving mooring practices, compliance with standards,
improving operational efficiency and ensuring the safety of port operations. The
methodology involves collecting data on tensions in mooring cables through detailed
instrumentation and statistical analyses. Also consider reviewing good port practices
and maritime safety regulations. It is expected that the research results will provide
relevant information for the Terminal, allowing improvements in the operations of the
mooring system, as well as real-time monitoring of the cables, which helps in decisionmaking when necessary, adjustments need to be made. This helps to minimize the risk
of accidents, prevent damage to infrastructure and shipping, and avoid operational
delays.

Abstract: Aquaculture is the fastest-growing food production activity worldwide, driven mainly by
population growth, economic profits, and demand for alternatives to terrestrial livestock
production. There is great expectation that Brazil will become one of the world's leading
producers of aquatic foods, and the environmental and procedural challenges of the
activity must be overcome to achieve this national aquaculture potential. Mitigation and
control strategies for undesirable compounds, such as bioremediation with
microorganisms, are gaining attention in aquaculture management and improving the
technical and financial viability. However, the use of these microorganisms has
significant limitations that need to be considered, particularly regarding the definition of
the most efficient microbial consortia and protocols for their use. The research proposed
here aimed to evaluate the action of multispecific microbial bioremediators (fermented
Endogenic Efficient Microorganisms – EEM, prospectively obtained from the riparian
forest, Non-Sulfur Purple Bacteria - BPNS, and a commercial formulation - Stability®)
which were applied in artificially eutrophicated liquid media. Physicochemical
parameters (temperature, OD, pH, and electrical conductivity) and chemical parameters
(alkalinity, hardness, ammonia, nitrite, nitrate, total phosphorus, phosphate, phosphorus
pentoxide, and carbon dioxide) were determined before and after the addition of
bioremediators at 6, 12, and 24 hours post-treatment. The results indicated that the
treatment with BPNS was the most effective in reducing ammonia (90% - 24h), and
phosphate (64% - 24h). The treatment with EEM also reduced levels of phosphate (41% - 24h), however, despite the observed ammonia consumption up to 12 hours of testing
(60%), there was a significant increase in ammonia concentration at 24 hours (188%).
Considering the dynamics observed in water quality parameters, especially those related
to the buffer system (alkalinity, hardness, and pH), in addition to the reduction of
ammonia and phosphorus, the simultaneous application of these bioremediators (EEM
and BPNS) may promote synergistic effects, therefore recommending the evaluation of
the combined effect of these microbial consortia in future studies. Furthermore,
identifying microbial groups is essential for risk assessment when considering
aquaculture applications.

Abstract: There are many variables involved in navigation processes. It is of fundamental
importance that they are known and that they are aware of their degree of
influence on deviations that violate international maritime standards and good
seamanship practices. The present work aims to analyze the behavior of vessels
destined for the Ponta da Madeira Maritime Terminal (TMPM) after arrival at the
access channel, and will seek to find a pattern that leads to the materialization of
occurrences that pose a risk to navigation. For this to happen, it is necessary to
understand the production process in a comprehensive way, bringing the
characteristics of the São Marcos Estuarine Complex (CESM), its climatic
aspects through the survey of meteoceanographic data (tides and currents), in
addition to factors intrinsic to the activities that are most often not observed, such
as particularities of shipowners, vessels and crews. The work will show the global
relevance of TMPM, highlighting the need for favorable conditions for servicing
ships, always aiming for safety and minimizing risks. From the perspective of a
Local Port Service (LPS), a technological maritime monitoring system,
assessments will be prepared, which if well interpreted, may generate not only
reactive actions, but of a preventive and continuous nature, such as the review
of procedures for work on the main weaknesses and promote continuous
improvement.
