Power from renewable sources would play a key role in the future of electricity .The wind energy is one of the goal of EU's commitment, which want to develop offshore wind potential [1], [2]. Lubrication of wind turbines is very important for maintenance [3] . The purpose of this paper is to present some considerations about monitoring oiling system. This system monitors kinematic data in real time. The importance of monitoring real data with this system help us to simulate lubrication for various types of wind turbine reducers in order to choose the optimal form of the lubrication system and for good maintenance.

A The novelty of this study consists in the fact that, at the same time as the monitoring and acquisition of data of the air quality (from inside and outside), a monitoring and acquisition of data of the real-time biometric measurements of subjects exposed directly to the needle will be made. Medium by means of a bracelet attached to the subject's arm. This bracelet is designed to perform biometric measurements without creating discomfort to the subjects analyzed in the activities in which they are involved. This measurement is carried out with 9 different sensors for: pulse, oxygen in the blood, air flow (breathing), body temperature, electrocardiogram, galvanic skin response, blood pressure, the patient's position/movement, and the status of muscle (electromyography sensor). The data thus obtained will be focused on a PC and subsequently analyzed. The results of monitoring the health parameters of the subjects analyzed find application in the maritime field, to ships, especially in the engine room, where the air suffers quality transformations. The crew's return to the workplace may decrease due to the degradation of the air quality in the premises.

A smart solution for assessing the consequences of pollution on the coast, on flora and fauna but also by accounting for the total costs of the equipment used in the response to pollution is a system for assessing, coordinating and simulating the risk situation with the help of a mathematical model implemented on a simulator. The mathematical model for the simulation of the event of pollution is the latest generation and take into account all the meteorological factors of the sea and air, as well as all the physico-chemical parameters of the substances involved (dispersion, surface tension). The simulator is used for the realistic modeling of a crisis situation and it is useful for both marine officers and emergency situation officials. The simulator will be used as an educational instrument enabling the interactive study of the different emergency situations. In this paper we present the simulation of incident and the creation of response resources. The scenario incident is for KAPTAN M cruise ship that left the tourist port of TOMIS Constanta, Romania, having on board 20 passengers and a number of 15 crew members, and which collided with the oil ship EVIA Oil FIVE, having on board the quantity of 4200 MT crude oil. As a result of the collision, the passenger ship suffered a breach (water hole), on the starboard board, breach by which the ship began to ambarce sea water and in the car compartment a fire was produced. Containment and recovery of an oil spill during the exercise will be simulated through activation and control of response resources. The resources involved in the operations are divided into: platforms, equipment and personnel. The results of simulation is the list of response resources specified in the scenario together with their parameters, which can be exported into a text file. With this simulation tools you can efficiently appreciate the cost of resources in due time, avoiding material and human damage.

There are several operations which must do to maximize the performance of tank cleaning. The new advanced technologies in tank cleaning have raised the standards in marine areas. There are many ways to realise optimal cleaning efficiency for different tanks. The evaluation of tank cleaning options means to start with audit of operations: how many tanks require cleaning, are there obstructions in tanks (e.g. agitators, mixers), what residue needs to be removed, are cleaning agents required or is water sufficient, what methods can used for tank cleaning. After these steps, must be verify the results and ensure that the best cleaning values can be achieved in terms of accuracy and reliability. Technology advancements have made it easier to remove stubborn residues, shorten cleaning cycle times and achieve higher levels of automation. In this paper are presented the performances in tank cleaning in accordance with legislation in force. If tank cleaning technologies are effective, then operating costs are minimal.

The Potential Emergency Situations Simulator (PESS) for Constantza Maritime University (CMU) should provide training and practicing of the students or course attendants in choosing the best strategies in a given emergency situation, which is an informational high entropy, multi-tasking, fast changing environment. The simulator is used for the realistic modeling of a crisis situation and it is useful for both marine officers and emergency situation officials. The simulator will be used as an educational instrument enabling the interactive study of the different emergency situations. It has the aim of training students to efficiently react to emergency situations such as a leak from a ship/chemical plant, fire, poisonous gas emissions, or any other situations that could show a potential danger. The trainee must be provided with realistic information and the response of the model on the actions of the trainee must be in accordance with the real conditions and scientific based. It must be possible to accelerate the simulation speed without loss of information or functionalities. The input of the external weather conditions is a must, as well as the trainee-oriented graphic interface. It must be possible to change the chemical and physical properties and characteristics of the different polluting agents. The simulator is also used to evaluate the best strategies to be followed in an ongoing crisis. In order to fulfill this aim, the simulation must have the capability to receive data from various sensors, transducers and servers. The courses are designed to accommodate up to six course participants. Each course includes course material such as course manuals and other documents. The courses include hands-on experience with simulator operations and maintenance. To help the start up of the simulated emergency situations training at Constantza Maritime University, we have made a manual which includes some well-designed exercises with scenarios, initial conditions and relevant documentation. The exercise documentation includes the exercise objectives, exercise guidance, instructor guidance, expected results and all other information to make the exercise successful for an inexperienced instructor.
