Wave Energy Prize presentation from the April 2015 National Hydropower Association and International Marine Renewable Energy Conference in Washington, D.C.
This document summarizes wave energy technology and resources. It discusses the physics of wave energy and types of wave energy conversion technologies including oscillating water columns, tapchans, pendulors, wave dragons, power buoys, pelamis, archimedes wave swings, and bristol cylinders. It also outlines major wave power plants worldwide and India's wave energy program, including a 150 kW pilot plant in Vizhinjam, Kerala. The document covers advantages and disadvantages of wave power as well as challenges in the field.
Wave energy has significant potential as a renewable energy source. Ocean waves are generated by wind blowing across the water surface. The amount of energy in a wave depends on wind speed, duration, and the distance over which the wind blows known as fetch. Worldwide, the potential for wave energy has been estimated at over 2,000 terawatt hours per year, which is around 10% of current global electricity consumption. Several types of devices have been designed to capture the energy from ocean waves, such as the Wave Dragon which uses a reservoir and low-head turbines to convert wave motion into electricity. Wave energy offers a large, renewable resource but development has been limited by high costs and the need for suitable coastal locations with consistently strong wave
Wave power is a renewable energy source that can be harnessed using three main types of collectors: buoyant moored devices that float on the surface or below, hinged contour devices that follow wave motion at joints to create power, and oscillating water columns where wave motion acts like a piston to pump air and drive a turbine. Future prospects for wave power include the first US license granted to a company for a wave project and an agreement for a two megawatt wave energy project off California's coast.
Introduction:
With a growing focus on renewable energy, interest in the wave energy has also been expanding. Ocean waves are a huge, largely untapped energy resource, and the potential for extracting energy from waves is considerable. The paper describing one of the recently invented and developing wave energy converter, namely Oyster Wave energy converter.
In response to the need to find additional sources of renewable energy to combat climate change, ensure domestic energy security and develop new industries a large community of wave energy researchers and commercial device developers has arisen in recent years, pursuing a considerable number of different technologies for the conversion of wave energy. A company named, Aquamarine Power Ltd. had invented its new model of wave energy converter and named it as Oyster.
Construction:
Oyster harnesses the energy of near-shore ocean waves. It was designed to operate in water 10 to 12 meters deep. The Oyster is made up of a Power Connector Frame (PCF) and a Power Capture Unit (PCU) or oscillator. The PCF is bolted to the seabed by 1-by-4 meter concrete piles that are drilled 14 metres deep into the seabed. The PCF requires careful and accurate positioning and leveling to compensate for the uneven, rocky seabed.The PCU is a 200-ton, 18-by-12-by-4 metre buoyant flap that is hinged to the PCF. In order to lower the PCU into the water to hinge it to the PCF, 120 tons of seawater must be pumped into ballast tanks within the PCU to provide sufficient negative buoyancy to aid its descent into the water. The PCU is almost entirely submerged underwater; only 2 metres of the device poke above the water. It has two hydraulic pistons connected by two sub-pipes streched upto the shore.
working:
With the movement of the waves, The PCU or oscillator sways back and forth, and this movement of the flap drives two hydraulic pistons that pump high-pressured water through sub-sea pipeline to an onshore hydro-electric water turbine. The turbine then drives an electrical generator, which converts the wave energy into electricity. The water exhausted from the turbine returned back to the sea.
Aquamarine Power has developed a wave energy converter called Oyster, which is the world's largest at 40MW capacity. It was installed at EMEC in Scotland. Previously the largest was only 2.4MW in the UK. Oyster uses the motion of a hinged flap from wave movement to drive hydraulic pistons, which pressurize water to turn a turbine and generator on shore to produce electricity in an efficient hydro-electric process. Oyster is estimated to operate efficiently for 15 years and provide reliable, eco-friendly energy from the ocean.
The document summarizes the development of a 1.5 MW Wave Dragon North Sea Demonstrator. It discusses the Wave Dragon technology which uses wave energy focusing and overtopping to fill an above sea level reservoir, from which low-head variable speed propeller turbines generate power. A 57m wide 200 tonne Wave Dragon prototype was deployed in 2003 and connected to the grid, representing the world's first floating wave energy converter. The document outlines objectives to develop larger 4-11 MW Wave Dragon power plant units with a production price of 0.04 €/kWh by 2016.

How Advanced Simulation will Impact the Offshore Industry both Now and in the...Altair
The easy days of Oil and gas extraction is over, and the ability to extract Oil and Gas from harsh enviornments is very dependent on the ability to overcome technical challenges through the use of advanced numerical analysis and simulation. Technical challalenges currently faced in the industry include High Pressure High Temperature (HPHT), Utra Deep Water (UDW) with water depths greater than 10,000 ft, and the Arctic with potentially 20% untapped hydro carbon reserves. These technical challenges are overcome through more use of advanced analysis and simulation, and this allows cost effective solutions to be obtained.
Also the Industry is currently being challenged by a low oil price, and lots of companies are forced to look at cost and schedule. This as a result, allows the opportunity for the use of advanced analysis to help solve Engineering challanges in an efficient manner and save potentially millions of dollars in the Engineering. The ways that this is undertaken is presented and discussed.
There are different types of Analysis simulation used in the Offshore Industry, for example FEA, CFD, Coupled Analysis etc. Also computer power is ever increasing in compuational efficiencies, and novel methods, such as the use of Cloud computing, has had a big impact on the way that analysis is undertaken. These different methods of software and hardware are discussed in relation to the Offshore Industry, and an indication is given in to how these methods will affect the Industry in the future.

A Guide to AI for Smarter Nonprofits - Dr. Cori Faklaris, UNC CharlotteCori Faklaris
Working with data is a challenge for many organizations. Nonprofits in particular may need to collect and analyze sensitive, incomplete, and/or biased historical data about people. In this talk, Dr. Cori Faklaris of UNC Charlotte provides an overview of current AI capabilities and weaknesses to consider when integrating current AI technologies into the data workflow. The talk is organized around three takeaways: (1) For better or sometimes worse, AI provides you with “infinite interns.” (2) Give people permission & guardrails to learn what works with these “interns” and what doesn’t. (3) Create a roadmap for adding in more AI to assist nonprofit work, along with strategies for bias mitigation.

Combined Illegal, Unregulated and Unreported (IUU) Vessel List.Christina Parmionova
The best available, up-to-date information on all fishing and related vessels that appear on the illegal, unregulated, and unreported (IUU) fishing vessel lists published by Regional Fisheries Management Organisations (RFMOs) and related organisations. The aim of the site is to improve the effectiveness of the original IUU lists as a tool for a wide variety of stakeholders to better understand and combat illegal fishing and broader fisheries crime.
To date, the following regional organisations maintain or share lists of vessels that have been found to carry out or support IUU fishing within their own or adjacent convention areas and/or species of competence:
Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR)
Commission for the Conservation of Southern Bluefin Tuna (CCSBT)
General Fisheries Commission for the Mediterranean (GFCM)
Inter-American Tropical Tuna Commission (IATTC)
International Commission for the Conservation of Atlantic Tunas (ICCAT)
Indian Ocean Tuna Commission (IOTC)
Northwest Atlantic Fisheries Organisation (NAFO)
North East Atlantic Fisheries Commission (NEAFC)
North Pacific Fisheries Commission (NPFC)
South East Atlantic Fisheries Organisation (SEAFO)
South Pacific Regional Fisheries Management Organisation (SPRFMO)
Southern Indian Ocean Fisheries Agreement (SIOFA)
Western and Central Pacific Fisheries Commission (WCPFC)
The Combined IUU Fishing Vessel List merges all these sources into one list that provides a single reference point to identify whether a vessel is currently IUU listed. Vessels that have been IUU listed in the past and subsequently delisted (for example because of a change in ownership, or because the vessel is no longer in service) are also retained on the site, so that the site contains a full historic record of IUU listed fishing vessels.
Unlike the IUU lists published on individual RFMO websites, which may update vessel details infrequently or not at all, the Combined IUU Fishing Vessel List is kept up to date with the best available information regarding changes to vessel identity, flag state, ownership, location, and operations.

14. Department of Navy Energy Program
• Energy Security is achieved by utilizing sustainable sources that meet tactical, expeditionary, and shore operational requirements and
force sustainment functions, and having the ability to protect and deliver sufficient energy to meet operational needs.
• Energy Independence is achieved when Naval forces rely only on energy resources that are not subject to intentional or accidental supply
disruptions. As a priority, energy independence increases operational effectiveness by making Naval forces more energy self-sufficient
and less dependent on vulnerable energy production and supply lines.
