Offshore Wind Farms
Sabik Offshore has dedicated itself to designing products and systems specifically for use in offshore wind farms. We’ve taken extra care to develop components that are easy to handle, to install and to commission.
Marking Offshore Wind Farms
PART I – Why Marking Offshore Wind Farms is important?
Marking Offshore Wind Farms provides a crucial function during development and operation to ensure the safety of mariners, pilots and service personal as well as the assets themselves. Sabik Offshore is a leader in marking offshore wind farms worldwide.
PART II – How to mark an Offshore Wind Farm?
There are many techniques to marking an offshore wind farm such as cardinal buoys, temporary lighting, aids to navigation, AIS, ID marking, fog signals and aviation obstruction lighting. Here we give you a short overview of the purpose of each technique.
PART III – How does the marking system work?
After installing your aids to navigation, AIS, ID marking, fog signals and aviation obstruction lighting, you need to tie it together in a system. The NAi system brings all marking methods together into a cohesive system that is monitored and controlled. This concludes our three part series on marking offshore wind farms.
Individual Marking Methods
In our day to day life, we recognize universal symbols of a construction site: cones, red striped tape and concrete barriers or large temporary walls. But what about an offshore wind farm? How do we communicate that this vast span of water is a construction site?
How do we keep these obstructions visible and the area safe during construction? The foundation is in the water. Maybe even the Transition piece is also installed. But there’s no power to the marking system.
Does an offshore turbine have an address? Each turbine has specific coordinates. These would get too big and complex to communicate.
The fundamental marking element of an offshore windfarm is the marine lanterns. Typically 2 & 5 nautical mile lanterns mark the perimeter of an offshore windfarm.The lanterns are all synchronized to provide a uniform signal that there is a “large” obstruction in the water.
During times of low visibility, a fog signal warns a mariner that they are close to danger. An offshore wind farm poses a unique challenge since it is an artifical “island” spanning many kilomters or miles. Modern simulation software helps us determin the best position for every fog singal on an offshore wind farm so that we get 100% coverage all the way around the wind farm.
Digital Marking – AIS
Modern commercial vessels use digital maps. In order for a vessel or wind farm to show up on these maps, you need to transmit an AIS (Automatic Identification Signal). The object name, type of obstruction as well as the longitude and latitude of the structure then appear on a mariner’s digital map.
Whether it’s a helicopter approaching the wind farm or low flying airplanes passing by, there is an inherent risk with turbines and their blades rising out of the water. Aviation lights help pilots navigate around or through an offshore windfarm.
Marking the Construction
Site of Kriegers Flak
In the spring of 2020, SABIK Offshore has been commissioned to mark the construction site of the Kriegers Flak offshore wind farm in the Baltic Sea. During February 2020 our team launch the 29 yellow buoys.
Installation of Original
The Original NAi product line is a set of high quality navigational aids, developed for dependable operation in the harshest offshore environment. In this video we go over proper installation procedures for the Original NAi product line.
