ABB Power Systems posted pre-tax earnings of $9 million for Q3, down from $141 million in the same period last year.
The connection specialist said the decrease in earnings was due to "project-related costs" in offshore wind.
Power Systems' order book swelled in the quarter as well. It received $2.2 million in orders in the third quarter, compared to $1.2 million in Q3 last year.
In the quarter, ABB was handed deals to supply cables to Dong Energy's off the UK's west coast. It will also deliver a transmission link for Vattenfall's in the German North Sea.
ABB group net income fell 13% for the quarter from $1.6 billion to $1.4 billion.
