First US Offshore Wind Installation Vessel to be Built with Oil and Gas Expertise  :o  ;D

Expected delivery of the Jone-Act-compliant vessel is late 2018.

June 30, 2017

By Jennifer Runyon Chief Editor

SNIPPET:

The vessel will be based on a US-built barge. Zentech plans to install four truss legs with spud cans, a proven oil and gas design, and integrate them into a newly built hull.

In late 2016, the first U.S. offshore wind farm was commissioned off the coast of Rhode Island. In constructing the Block Island Wind Farm, developer Deepwater Wind had to use a wind turbine installation vessel —Fred Olsen Windcarrier’s Brave Tern — from Europe because no boat big enough to install the vessels existed yet in the United States. Because of U.S. regulations in the Jones Act, Brave Tern was not permitted to touch the shore , meaning that other U.S.-flagged vessels had to transport equipment from the U.S. coast to the installation site, adding additional cost to the installation of the project.  >:(

The Zentech and RRI vessel will solve that logistical headache. The company said that the vessel will also act as an oil and gas crane jack-up for decommissioning in 300-ft water depths when not in service for installing and/or maintaining wind turbines.

Design of the Jones Act vessel should allow it to navigate the New Bedford Hurricane Barrier, the company said. It will be able to carry and install components for at least three complete turbines, up to 9-MW capacity  , according to the company. The vessel’s jacking system will be rated at a capacity of 16,000 tons, extending the unit’s service life.

The company said that the vessel may one day be able to install four 8-MW fully assembled wind turbines and will be ready for anticipated 10-MW capacity machines in the future.

“With larger scale offshore wind projects following Block Island, the U.S. market requires forward-looking marine logistics,” said Andy Geissbuehler, Managing Partner of Renewable Resource International.

Video spotlight: How to build and maintain wind farms 

We’re right at summer’s midpoint, and news this time of year can be a little slow. But these warm weather months don’t mean a slow down for the men and women building and maintaining wind farms.

The long days and clear skies have them forging ahead with new construction and routine upkeep. Here’s a trio of videos providing some insight into what they’re up to:

Xcel Energy shows us the steps that go into building a wind farm:



E.ON takes a look at how you keep wind turbine blades in tip top shape once a project is up and running:


Finally, Acciona explains how these construction and maintenance procedures let us generate electricity out of thin air:

Why do wind turbines have 3 blades? ???

Hint: Cost of blades and centrifugal force considerations.
