Energy harvesting is a concept by which energy is captured, stored, and utilized using various sources by employing interfaces, storage devices, and other units. Ocean wave energy harvesting in which the kinetic and potential energy contained in the natural oscillations of Ocean waves are converted into electric power. The kinetic energy harvesting system could be used for a number of areas. The main applications that we have discussed in this paper are to how generate the energy from Ocean wave energy (kinetic energy) to electric energy that is to eliminate the requirement for continual battery replacement.

This research studies offshore oil and gas plat-forms after the exhaustion of hydrocarbon reserves. As an alternative to dismantling ways of reequipment of the promising facilities in the Arctic region for power generation are presented. Also a common problem of the infrastructure of offshore oil and gas fields after the end of their operation life is considered. One of the dif-ficult issues that is faced by oil-producing organizations is how to utilize the offshore platform? The hypothesis of infrastructure functionality of offshore platform was put forward for the other types of energy production. In the future, reequipment of offshore platforms will pro-vide an opportunity to reduce costs in the field of con-servation and optimize the environment. The methods for the development of design so-lutions selected by the authors allow us to consider an offshore platform after its operation as an element of culture development and a tool of ecological rehabilita-tion of the offshore area. This makes it possible to con-sider the prospects for the marine infrastructure growth and to improve the economy of coastal areas. The re-construction of offshore platforms with the change of their function will allow forming a developed maritime infrastructure in coastal waters. The ability to transport some of the offshore platforms after the oil and gas end will allow building a network 50 km away from the coastline. The authors carried out design experiments based mostly on fixed offshore platforms, regulated by the rules of the Rus-sian Maritime Register of Shipping and by SNIP 2.07.01—89*1. The authors developed the basic requirements for the selection of priority projects for the analysis, which are the characteristics of the waters suitable for the use of renewable energy sources and location of offshore platforms less than 50 km away from the coast with a small average water depth of 50 to 110 meters. Thus, the presented the concept of reconstruc-tion can be considered a coastal project.

The world's population continues to grow at a quarter of a million people per day, increasing the consumption of energy. This has made the world to face the problem of energy crisis now days. In response to the energy crisis, the principles of renewable energy gained popularity. There are much advancement made in developing the wind and solar energy farms across the world. These energy farms are not enough to meet the energy requirement of world. This has attracted investors to procure new sources of energy to be substituted. Among these sources, extraction of energy from the waves is considered as best option. The world oceans contain enough energy to meet the requirement of world. Significant advancements in design and technology are being made to make waves as a continuous source of energy. One major hurdle in launching wave energy devices in a developing country like Pakistan is the initial cost. A simple, reliable and cost effective wave energy converter (WEC) is required to meet the nation-s energy need. This paper will present a novel design proposed by team SAS for harnessing wave energy. This paper has three major sections. The first section will give a brief and concise view of ocean wave creation, propagation and the energy carried by them. The second section will explain the designing of SAS-2. A gear chain mechanism is used for transferring the energy from the buoy to a rotary generator. The third section will explain the manufacturing of scaled down model for SAS-2 .Many modifications are made in the trouble shooting stage. The design of SAS-2 is simple and very less maintenance is required. SAS-2 is producing electricity at Clifton. The initial cost of SAS-2 is very low. This has proved SAS- 2 as one of the cost effective and reliable source of harnessing wave energy for developing countries. {"references": ["Richard Boud, \"Status and Research and Development Priorities, Wave\nand Marine Accessed Energy,\" UK Dept. of Trade and Industry (DTI),\nDTI Report # FES-R-132, AEAT Report # AEAT/ENV/1054, United\nKingdom, 2003.", "N.

Structure-borne noise is an important aspect of offshore platform sound field. It can be generated either directly by vibrating machineries induced mechanical force, indirectly by the excitation of structure or excitation by incident airborne noise. Therefore, limiting of the transmission of vibration energy throughout the offshore platform is the key to control the structureborne noise. This is usually done by introducing damping treatment to the steel structures. Two types of damping treatment using onboard are presented. By conducting a Statistical Energy Analysis (SEA) simulation on a jack-up rig, the noise level in the source room, the neighboring rooms, and remote living quarter cabins are compared before and after the damping treatments been applied. The results demonstrated that, in the source neighboring room and living quarter area, there is a significant noise reduction with the damping treatment applied, whereas in the source room where air-borne sound predominates that of structure-borne sound, the impact is not obvious. The conclusion on effective damping treatment in the offshore platform is made which enable acoustic professionals to implement noise control during the design stage for offshore crews' hearing protection and habitant comfortability. {"references": ["D.
