40-Year Maintenance Free Coating Solution for Offshore Structures

Product Number: 51324-20591-SG

Offshore assets such as those found on wind farms are being designed to have extended lifetimes of more than 40 years to offer a sustainable form of energy generation. With offshore maintenance considered a hazardous and expensive process, owners are looking for low or maintenance free solutions to protect their assets. The challenge to the coating manufacturer is twofold, firstly to design a coating system that offers a maintenance free solution in a highly corrosive environment and secondly demonstrating long term performance. This paper will describe a 40-year case history of a coating system applied to the hull of a offshore TLP with submerged, splash/tidal, and atmospheric zone. We will describe both the technology approach using high loadings of lamellar glass flake to enhance both abrasion and mechanical properties and secondly demonstrate the in-service properties of the coating system after 40 years exposure including visual appearance, adhesion, cross sectional optical microscopy and electrical impedance spectroscopy (EIS). The coating integrity has been well maintained by a multiple coating application. We will discuss the key product attributes that are relevant to providing a high durability coating solution for extreme environments. We will also introduce a new international standard related to the offshore wind industry with particular focus on extending asset lifetime through appropriate coating specification and selection.

51317--9364-New Developments in Coatings for Extended Lifetime for Offshore Wind Structures

Product Number: 51317--9364-SG

ISBN: 9364 2017 CP

Author: Jakob Mølholm

Publication Date: 2017

$20.00

Requirements for corrosion protection for new large offshore wind farms are extended to 25 years’ maintenance-free service lifetime. Therefore, ISO 12944 is being updated. To bring down construction cost for offshore wind, initiatives have been taken to industrialize the coating application process and use standard components.

Back in 1991 the first offshore wind asset was constructed in Denmark near the coastline from Vindeby (which means windy city). This asset comprised 11 foundations with a capacity of 0.36 MW each. Since then; the offshore wind industry has been booming, and projects are becoming bigger and bigger in size (capacity), number of foundations per site and further and further offshore.

Cathodic protection within narrow gaps of offshore wind turbine foundations

Product Number: 51320-14750-SG

Author: David Buxton, Petra Ernst, Gareth John, Tom Wewer

Publication Date: 2020

Cathodic protection (CP) is routinely applied to the external surfaces of offshore wind turbine monopile foundations to minimize corrosion. When the monopile internals are free-flooding, and therefore also exposed to oxygenated seawater, again, cathodic protection may be applied. In cases of unplanned water exchange through cable entry seals, a small additional surface area, in a gap between the seal and the ‘cable entry hole’ through the steel monopile is then exposed to flowing seawater. Cathodic protection calculations were undertaken to assess whether protection (either applied externally or externally and internally) could penetrate into the small gap and prevent corrosion.

Corrosion and Corrosion Protection of Offshore Wind Energy Towers

Product Number: 41211-635-SG

Author: Andreas W. Momber

Publication Date: 2011

$20.00

The paper provides a review about the corrosion and corrosion protection of offshore wind energy devices (OWEA) with a focus on the support structure. Firstly, special features resulting from location and operation of wind energy devices offshore are being discussed. This includes the definition of a load collective. Secondly, types of corrosion and corrosion phenomena are summarized in a systematic way.

Duplex Zinc Coatings for Offshore Wind Towers

Product Number: 51324-20688-SG

Author: M. Gagné

Publication Date: 2024

$40.00

Proven corrosion protection coatings for the towers of offshore wind turbines (OWT) are critical for the financial viability of the asset. Duplex zinc coatings were used to protect the towers on the first offshore wind farms in the North Sea and their exceptional performance during the 25-year design life of the windfarm underscores their continued use in this application. Financial models show the significant benefit of eliminating the need for corrosion maintenance on OWT towers over the life of the structure.

Long Term Performance Of Glassflake Reinforced Polyesters - A Case Study After 35 Years Under Offshore Conditions

Offshore wind farms are important contributions to the growing need for the generation of renewable energy. The number of offshore wind farms is growing, and multiple projects are under planning and construction around the world. One key element for a profitable and sustainable operation of offshore wind farms is that the installations are protected with the most cost-effective corrosion protective solution for the entire lifetime of the offshore wind farm. In practice, this means that today’s projects are planned with an estimated lifetime of a minimum of 35 years without major maintenance of the corrosion protective solution. To achieve this it is instrumental that the entire lifetime cost is considered when a corrosion protective solution is selected.
