The 300 jobs will be taken from all of Aibel's operations in Norway, but with a focus on its Stavanger, Oslo, Haugesund and Stjordal sites.
Aibel said the move was because of a "reduced workload". The group has announced just five contracts this year, only two of which are located in Norway.
Job cuts have been taking place since March 2014, when Aibel announced 230 job losses at its Norwegian, UK and Singapore offices.
In August, Aibel said another 250 jobs would be axed and then, at the start of October, a further 230 positions would be lost.
This latest round means over 1,000 employees would leave their jobs at Aibel this year. The group said all figures include natural turnover.
A majority of Aibel's operations is focused on the offshore oil and gas sector, but the company was involved in building the DolWin Beta substation serving the 330MW Gode Wind 1 and 332MW Innogy Nordsee 1 offshore wind projects.
Aibel was also chosen by Norwegian utility Statoil to carry out engineering work on the Hywind floating project in Scotland.
