The paper strives to analyze the proportion of emissions from noxious combustion from a diesel engine and to suggest some methods of minimizing them prior to their discharge into the atmosphere. Even though cargo shipments or military applications on water account for less than 8% of all pollutant emissions emitted in the terrestrial atmosphere, it is not negligible that they also participate in the intense effort of the other components of thinning ozone layer. This state of affairs has a great impact not only on aquatic flora and fauna but also on the health of human life. Today's advanced performance technology, applicable to naval diesel engines equipping marine and river ships, largely addresses this environmental pollution problem, which is particularly sensitive to us all.

In the Black Sea, electrical light can attract, in certain periods, the following fish species: sprat, pontic anchovy, Azov anchovy, saurel, common grey mullet, tinker, etc. In the paper we do not present the results of the researches regarding the attraction modalities of this species by electrical light, but the system which the fish, concentrated near the light source, can be brought on board. One of the systems which can be used is air-lift pump. Airlift pump system is an installation based on principle of communicating vessels filled with no miscible liquids. Compressed air, introduced on the base of an underwater conduit, forms with the water a heterogeneous mixture gasliquid with a lower density than the liquid. We present below an original approach regarding this problem. After a theoretical study, the authors propose a system which could be used for fishing and for bringing the fish on board of fishing vessels.

The radiation scanning system is an innovative solution for scanning containers and freight wagons in a container terminal. The proposed solution will offer increased capacity for effective and continuous monitoring of realtime inspection and adjudication. it will also allow for the full legitimacy and full security of imports and exports, while at the same time applying the exact taxes and duties on all goods. The radiation scanning system equipment consists of a dual-energy rail scanner of the wagons and a dual energy portal (bi-directional portal to the container side - automatic container scanning. The portal is capable of detecting hidden threats and smuggling in densely packed trucks, freight containers and tanks, the portal is ideal for scanning operations at large sea ports, border crossing points and security points. With a compact footprint that allows installation in areas with limited space, the system can scan up to 200 trucks per hour. When it works, the system offers material discrimination, the coloring of orange organic objects and blue metal objects. As vehicles pass through the portal, high-quality images appear in real-time on a high-resolution monitor, allowing for immediate processing and analysis. Once the cabin and driver have passed through the system, the subsystem "informs" the X-ray source when the front edge of a container reaches the beam plane - and in milliseconds, the X-ray beam is on. The radiation inspection system is based on the lifecycle perspective, a perspective that relates, among other things, to the environmental requirements of the material supply chain, product life cycle controls, from the purchase of materials to product treatment end of its life cycle and waste disposal.

Maritime transport is the sector of the international economy that ensures the transport of people and goods in space. In other words, maritime transport within the global transport system is the economic activity through which trade is made between two points (one being the expedition and the other the destination) situated on land but separated from water. Maritime transport is considered - and rightly so - one of the most important international activities, the study of some aspects related to this field also involves the study of the world economy. That is why we can say that this type of transport is very sensitive to the events recorded globally. The operational equipment used in the container terminal is the main means of cargo handling both from the ship to the terminal and vice versa as well as within the storage / transport terminal. Of particular importance are the equipment targeted for indoor traffic. Port facilities involve costly investments but are imperative for efficient operation without overloading or neglecting the technical endowment of operators, as happened in some countries that have built new operating capabilities when the old ones were already very crowded or on the contrary, as long as they did not have the optimal load. All means of exploitation must be carefully calculated and should not lead to high economic costs for operators who have incorrectly operated or poorly maintained port facilities. The cost of these installations is generally not invoiced to the infrastructure user, and it is mainly borne from selffinancing.

This paper provides a brief overview of the Maritime Industry with focus on the seafarers being a number one choice in the global maritime arena as evidenced by the number of deployment of seafarers. A brief overview on the educational and training system in the Philippines with the concerned agencies (TESDA, DepEd, CHED, and MARINA) and their various initiatives have been analyzed primarily on the latest trend in MET namely: 2016 nationwide implementation of K to 12, OBE implementation and the Philippines Qualification Framework. MAAP as a MET provider and full supporter of the government initiatives is spearheading programs, projects, and activities aimed at ensuring a continuous supply of quality seafarers in the global maritime industry which this paper would like to share. This paper emphasized the need for a TVET quality assurance and a TVET Trainer/Assessors Qualification Standards in the Maritime Industry to ensure the success of the programs because the continuous training of human resources is the key to success. Technical-Vocational Livelihood (TVL) Maritime specialization and a Prebaccalaureate Maritime specialization are being offered to Senior Maritime High Schools which must be handled by qualified and certified TVL maritime teachers. The TVET policy framework and TVET qualification levels have been analyzed. This is timely as this may serve as a reference by MARINA in expanding them to come up with general MET teachers’ standards by incorporating the needed competencies (outcomes) and performance criteria for each qualification level. The paper ends with conclusions, recommendations, and projected implications/impact of quality assurance and qualification standards in the Maritime Industry thru innovations in TVET for socio-economic development

When we talk about globalization, then the partnership of the Philippines (MARINA) with global counterparts (IAMU, GlobalMET, IMAREST, NI, and APEC) in particular, is essential. This paper presents global activities that aimed to contribute to future global MET developments in the Philippines. MARINA and MAAP participated in both events and had noted essential ideas that need to be animated to develop MET in the Philippines in partnership with international MET organizations who share similar concerns and interest. First was the 2017 APEC meeting hosted by KIMFT in Korea, aimed at coming up with future MET direction of seafarers in the APEC region, with focus on enhancing seafarers’ global capabilities and promoting their successful entry into the global shipping industry. The second was the 2017 IAMU-PAES-P project aimed at improving the quality of academic curriculum; to improve the learning experience of all concerned and to analyse and improve the MET system’s organization. This paper presents the outcomes of both global conferences with a focus on the future Global MET developments in the Philippines in line with the Royal Institute Global Conference theme “Global Challenges and Future Directions in the Maritime Industry." Specifically, the paper presents, three distinct groups of knowledge, skills and attitudes (KSA) that will enhance the global competency. These are the empirically based knowledge and skills (basic competency, numeracy, science, and technology skills); the Higher-order cognitive and metacognitive skills (critical thinking and creative problem solving); and the Global dispositions, perspectives, and attitudes. As this paper had explored future MET developments in the Philippines, there is a need for the adoption of global skills in MET curricula, assessments, and pedagogy. Therefore, while we may not know what the MET and global maritime arena will look like in 2100, MET students who will benefit from this transformation movement globally, will be prepared to excel and succeed. This paper examines, summarizes, and offers solutions to what may be the biggest challenge facing the Philippine MET in the coming decades. The Philippines must possess maritime professionals or seafarers who demonstrate sufficient levels of global competency- the right skills, attitudes, and dispositions necessary to navigate and excel in a highly fluid, globalized, and increasingly competitive environment. This paper presents the role of MET in enabling Filipino students with the skills, aptitudes, and dispositions required to be efficient and competing in the current and the future globally interconnected and interdependent world system. The Paper ends with concluding remarks.

This paper analyses the state of risk that should be measured by an effective monitoring system of marine accidents in the Black Sea from an economic and ecological point of view. The analysis is performed using a set of 15 ecological-economic indicators. Indicators represent a valid tool to support the decision making process in marine risk management. Economic indicators include 6 indicators on economic performance, 4 on productivity, 2 on costs and prices, and one general indicator summarizing economic sustainability. From the ecological point of view, 2 indicators plus one general indicator summarizing ecological sustainability are defined. Particular attention is devoted to the selection and analysis of sustainability indicators. The standard distinction among environmental, economic, and ecologic sustainability has been held in this paper.

Leaving from a definition of risk (involving probability, vulnerability and capacity), authors make an introduction in the need to address oil pollution risk in the Black Sea, through proper and thorough organization of thinking. The most visible conclusion is that we have the knowledge in order to prevent oil pollution of the sea and we just need to action in advance, for preventing and not for intervention after oil pollution occurred. Following the risk management cycle is a good way of dealing the problem of oil pollution in the Black Sea.

The beach from Mamaia, one of the most important summer holiday resorts, is located in the southern part of the Romanian coastline and has a length of 8 km. The southern beach of Mamaia, with a length of 3.5 km is protected against coastal erosion by 6 submerged "breaking wave" type dams. The strong erosion of the Mamaia beach began since 1977, when the north breakwater of the Midia Harbor was prolonged up to the depth of 10 m. To stop the coastal erosion and to increase the asset value of the coastal zone and the creation of new beach areas have been established short and medium-term measures that include measures to reduce the wave energy reaching the shoreline, including recharging of sand and works made to retain the sand on the beach (by repairing the existing offshore breakwaters and the construction of new shore-normal groins).

The main focus of this article is the development and use of different types of modern marine propulsions. The main goal is the diversity of energy sources and the reduce of environmental pollution, hoping that this will ensure future energy security supply. I propose to show the advantages and disadvantages of different marine propulsions. The main reason of this article is to try to show a modality for reducing ship pollution and the quantity of fuel used, increasing the energy efficiency, that means, to reduce the price of transportation and a method of saving money for the owners. As a result of my research I discovered that is more convenient to use nuclear propulsion comparing with other conventional types of propulsions. In recent years, a lot of money had been invested in the development and research of security measures for nuclear propulsions, but most of them for military navy of highly developed nations. Nuclear propulsion is particularly suited to ships that need to be at sea for long periods of time without refuelling. Fuel costs are initially paid together with the reactor, initially high, but over time costs are attenuated.

Marine casualties are very critical issues for both maritime sector and the world. Due to generally large impact of marine casualties, there may be seen serious mortality, loss of property and financial, and environmental problems. The ships which are tanker type have more impact and dangerous on marine casualties because of due to the characteristics of the cargo that they carry. Bunker tankers, which are a type of tankers, are in close operation with the vessels when they serve their services. For this reason, the possibility of involved in a marine casualty of these ships is higher. In this paper, it was aimed to analyzed bunker tanker casualties, circumstances and their results. 204 bunker tanker casualty reports occuring between 1966 and 2017 were analyzed using Statistical Package for the Social Sciences (SPSS) 22.0 package. These reports were provided Information Handling Services (IHS) Markit Maritime Portal. According to analysis results, the most common types of casualties were determined as collision (32.8 %), hull and machinery damage (27.0 %) and wrecked/stranded (22.1 %), respectively. In addition, casualty involving injury or death and environmental pollution rates were found low, while almost half of the casualty reports were reported as serious.

Mariana trench is the deepest place on the Earth. It crosses four tectonic plates of the Pacific Ocean: Mariana, Caroline, Pacific and Philippine. The formation of the trench is caused by the complex interconnection of various environmental factors. The aim of this study was to describe and characterize various impact factors affecting formation of the Mariana trench geomorphology and continental margin environments using R programming language and mathematical algorithms of correlation methods written on R code. To record the system of geological, tectonic, geographic, oceanological and bathymetric features affecting Mariana trench, a combination of statistical methods, GIS and R programming codes were applied. The questions answered are as follows: which factors are the most influencing for the Mariana trench morphology, and to what extend do they affect its development? Is sedimental thickness of the ocean trench basement more important factors for the trench formation comparing to the steepness slope angle and aspect degree? Three methods of computing were tested: Pearson correlation, Spearman correlation, Kendall correlation, numerical correlogram, correlation matrix and cross-correlatios to analyze environmental impact factors. The correlogram matrices are computed and visualized by R scripting libraries. Complex usage of programming tools, mathematical statistics and geospatial analysis enabled to get a differentiated understandings of the hadal environments of the Mariana trench. The results revealed following three types of factors having the highest score: geometric (tg° slope angle), geologic (sedimental thickness) and tectonic structure. The results furthermore indicated that tectonic plates, sedimental thickness of the trench basement and igneous volcanic areas causing earthquakes play the most essential role in the geomorphology of the trench.

Navigation under sail has been known to people for at least a thousand years, having evolved with the advance of mankind, where the quest has always been towards shortening sailing time by optimal routing and pursuing top speed. With the development of computer technologies and automation in shipping, the art of conning a sailing craft has been transformed and enhanced to a new level. Great consideration is now given to the protection of the marine environment and the atmosphere from the ever-increasing carbon emissions, which has resulted in the rediscovery of wind-powered navigation. It is worth noting that the global demand for and purchases of medium and large sailing boats and motor yachts with sails have plummeted over the last 10 - 15 years. The effect of wind and seas on sailing ships operation is disproportionately greater compared to motor-driven vessels. For the purposes of safe navigation sailing crews must closely observe the parameters of sailing vessels’ movement, hydro-meteorological conditions and navigational aids’ operation. They provide essential information of the ship's position, course, heel angle and rudder angle, distance made good, the elements of the hydro-meteorological conditions as well as forthcoming weather forecast, etc. Present-day sailing relies on these parameters for the normal operation of the various automatic systems used in the handling of sailing vessels. A universal automatic system has not yet been developed that would incorporate all factors at play in the safety of sailing in such a dynamic environment. The modelling of such a system will ensure the safe and optimal movement of multi-masted sailing vessels, regardless of the hydro-meteorological conditions in the navigation area.

The Manning industry known as the recruiter and selector of Filipino seafarers to foreign ship-owners for the purpose of manning their oceangoing commercial vessels is on the crossroads in ensuring that the Philippines known as the manning capital of the world would sustain the market leadership of the Philippines in the global ship-crewing industry by constructively addressing a complex of internal issues that threaten competitiveness. While such is a perfectly legitimate aspiration, the larger goal must equally pay attention to the enormous pressures imposed by the external environment, mainly the matter of competition and non-traditional opportunities which emerge within the manning sector, including its direct links with the global maritime industry in which it thrives. The seafarers, predominantly men in the deck and engine positions but joined by a significant number of women in cruise ships, are deployed through the manning companies which select, hire and train them by virtue of contracts with the overseas operators or owners. Filipino seafarers are widely acknowledged by foreign ship-owners, called principals, for their ability to sail and operate merchant ships of all types with efficiency, safety, and general cost-effectiveness. This paper presents an analysis of the strengths, weaknesses, opportunities, and threats that are facing the Philippine Manning Industry for the year 2014-2015.

Technological evolution implies a great flexibility of production capabilities with strong influences on changing design concepts. The emergence of personal computers is also favored by a tendency to globalize design rules through specialized design programs. The overall picture of design processes is changing very quickly and is determined by the emergence of modern means that designers have at their disposal today. Computer problem solving has been a strong motivation, so that later hardware development and PC development have led to the emergence of software dedicated to mathematical problems. For over 20 years, Mathcad is the recognized standard in designing, documenting and collaborating with computers, calculation methods and algorithms in design. This paper proposes the design of the gear unit for a single speed gear using the mathcad program.

Energy Efficiency Design Index (EEDI) was introduced since 2013 for new ships as a measure to improve energy efficiency of sea going ships. This factor already has created a great influence on global maritime industry. However, any requirement related to the energy efficiency of inland vessels does not exist. This paper attempts to evaluate EEDI for inland oil tankers of Bangladesh. According to the results of this analysis, which has been based on 90 existing inland oil tankers, EEDI that was introduced for seagoing ships cannot be applied B for proper evaluation of inland oil tankers due to limitation of carrying capacity and installed main engine power. So, the main objective of this paper is to provide EEDI reference line for inland oil tankers of Bangladesh.
