Pulse delivers fatigue monitoring system for offshore wind farm

May 22, 2014

Pulse Structural Monitoring (Pulse), an Acteon company, has completed a subsea integrity monitoring project on behalf of DONG Energy at the Gunfleet Sands wind farm in the UK sector of the Southern North Sea.

Pulse supplied a system to measure the motion of a number of unsupported sections of subsea cable to determine the impact of tidal activity on the fatigue life of the cable. A technician checks INTEGRIpods prior to deployment.

Pulse supplied a system to measure the motion of a number of unsupported sections of subsea cable to determine the impact of tidal activity on the fatigue life of the cable.

The project began in November 2013 and included project management, sensor delivery, offshore support and post processing data analysis. Pulse used four of its INTEGRIpodTM motion data loggers, which provided a detailed record of the cable’s motions throughout the study period. This data was used to confirm the acceptable fatigue performance of the cable.

HBC divers were contracted to install the subsea data loggers.

*Research note* Wind Energy Operations & Maintenance Costs

Long term contracts have led to a higher cost profile for asset owners and contracted asset owner, due to the “partial wrap” or “full wrap” component warranty for blades, gearboxes, and generators. However, the global COVID-19 pandemic has had some material impacts on this trend with OpEx budgets that were rapidly slashed. Has this affected you?
*Research Note* Wind Turbine OEMs: Reducing your bill of materials cost opens new markets

One of the most important tools they have to open new market is to reduce the bill of material costs. Drawing on an example from Nordex Acciona, the following research note takes a look at their global product sales pipeline, bill of materials reduction trends, global turbine price trends as well as buying patterns.
*Research Note* Global offshore wind energy market & commercial outlook

The global offshore wind energy market is undergoing a period of explosive growth. The market could grow to a total of 584GW installed if the industry finds a way to unlock the US $1.432 trillion in investment required to develop the proposed capacity additions.
*Research note* Offshore wind energy technology & supply chain outlook

Facing a period of tremendous growth, the offshore wind energy sector must continue to expand the supply chain to gain maximum global leverage and fulfil its potential. Understanding technology growth patterns and how to position yourself in this changing market landscape will be critical.
