The Bermuda Testbed Mooring (BTM) has been deployed since June 1994 and provides the oceanographic community with a deep-water platform for testing and intercomparing new instruments. The mooring is located about 80 km southeast of Bermuda. Surface instruments collect meteorological and spectral radiometric measurements from a buoy tower. Measurements at depth include: currents, temperature, co...
Boating activities are one of the causes that threaten seagrass meadows and the ecosystem services they provide. Mechanical destruction of seagrass habitats may also trigger the erosion of sedimentary organic carbon (Corg) stocks, which may contribute to increasing atmospheric CO2. This study presents the first estimates of loss of Corg stocks in seagrass meadows due to mooring activities in Ro...
For long-term mooring buoy observatories in the deep sea far from coasts, we design hybrid system, named Mooring Buoys Observation System with Benthic Electro-optical-mechanical Cable (MBOSBC). The Electro Optical Mechanical (EOM) cable connects surface buoy, and benthic observation node, as transmission link of information power. Different traditional mooring, needs to accomplish energy data b...
Abstract Wind farms with shared mooring lines have the potential to reduce costs. However, such wind may encounter complex system dynamics because adjacent turbines are coupled. This paper presents an analysis of a focus on natural periods. We first apply Irvine’s method model both line and two-segment single lines. The response surface is proposed replace iterations catenary equations lines, r...
In the design of floating systems, three major system components need special attention: the floater, the mooring system, and the riser system. This paper will focus on one the most unique areas in the structural design of these components, namely, the fluid-induced effects on floating structure systems and the associated structural response. Due to the rapid growth in the offshore field, parti...
An offshore mooring system stations a ship-shaped installation in place while withstanding incoming loads from the marine environment with short-term and long-term uncertainties. This study aims to develop novel framework for analysing on floating systems, namely line tension, fatigue damage, hull bending moment, as function of layout design variables environmental random variables. The nonline...
The long-term goal of this work is an integrated defense system that provides protection of Navy assets, while in port, from the threat posed by covert swimmers. The general concept is to hail, deter, and/or incapacitate the threat by directing a controlled level of low-frequency acoustic energy at the target location. At the system level, the concept requires combining elements of target detec...
