Analysis Of Biofouling Effect On The Fatigue Life And Energy Performance Of Wave Energy Converter System, Shun-Han Yang, Jonas W. Ringsberg, Erland Johnson

MARENER 2017

This study presents an analysis of a wave energy converter (WEC) system consisting of a buoy, a mooring system, and a power cable connected to a hub. The design service life of the investigated WEC is 25 years. During this long period, its service life will be influenced by marine biofouling due to the biological activity in the water.

The purpose of this study is to investigate the effect of biofouling with regard to the energy performance of the WEC and the fatigue lives of the mooring lines and power cable. The marine biofouling is modelled by an increase in …

Compliant Strategy For Shipowners: A Decision Framework For Air Emission Reduction Measures, Fabio Ballini Dr., Aditya Srivastava, Aykut Ölcer Dr.

MARENER 2017

The main aim of the paper is to develop a decision framework for ship owners to comply with the emission reduction regulations. Various measures available to ship owners will be analysed. This paper will discuss the need of Carbon Tax or Market Based Measures in the maritime market. A comparison between the market-based measures, operational measures, carbon tax and abatement measures for averting air emissions of carbon equivalent will be made.

An overview of air emissions caused by the shipping sector will be given along with the methods to keep records of air emissions. There are no uniform standardised methods …

High-Order Mooring Simulations For Increased Accuracy In Wave Energy Applications, Johannes Palm, Claes Eskilsson, Lars Bergdahl

MARENER 2017

The prevailing simulation technique for floating wave energy converters (WECs) is to use the linear hydrodynamics in convolution form to solve for the motion of the floating structure. This allows for very fast time domain simulations with the possibility to include non-linear reaction forces from e.g. moorings and power take off (PTO). Although its accuracy for very large motion amplitudes is debated (Yu and Li 2015, Palm 2015), it is the best method available to make long-term simulations of WEC response.

Brown and Mavrakos (1999) showed a big difference in mooring response depending on how the mooring cables of marine …

Energy Consumption Of Small Scale Fishing Vessel Operations In Indonesia: A Case Study In Palabuhanratu, Indonesia, Vita R. Kurniawati, Richard W. Birmingham, Alan J. Murphy

MARENER 2017

About 79% of the global fishing fleet is small motorized boats typically operating in coastal areas, supplying local markets, and contributing to human well-being through food supplies and economic development. For example, Indonesian fisheries which predominantly are artisanal fishing, have supported 54% of animal protein intake, accounted for 2% of employment level and increased the fishermen’s prosperity index by 2.44%. However, they cause significant environmental impacts including fish resource depletion and intensive energy use. Balancing the benefits and challenges, sustainably managing these fishing operations is an important yet complex task given the requirements to proportionally account for fish resources, fishing …
