Demand for offshore wind staff will triple by the end of the decade, surging to 868,000 full-time jobs from an estimated 297,000 in 2020, according to analysis by Rystad Energy.
The researchers said the hiring spree will already be visible in the middle of the decade, as job demand could reach about 589,000 in 2025.
Rystad Energy estimates offshore wind installed capacity could rise to 110GW by 2025 and 250GW by 2030.
It said the prolific growth will require a lot of skilled employees.
Rystad calculated the staffing needs in the number of full-time equivalent workers – one year of full-time employment for one person regardless of actual hours – and included only direct and indirect jobs driven by offshore wind capacity deployment globally.
Direct jobs relate to development manufacturing, construction, installation, and the operation and maintenance of offshore wind farms.
Indirect jobs relate to materials and services consumed, such as workers in steel plants supporting offshore wind turbines, electronics workers at companies supplying nacelle components, and staff of renewable energy regulatory institutions.
The jobs are grouped as construction and development (C&D) – which are typically capital expenditures – and operation and maintenance (O&M) roles – which relate to operational expenditures.
The C&D jobs are expected to account for most of the employment over the next decade, although its share of the total employment decreases as 2030 approaches, Rystad said.
O&M jobs, meanwhile, driven by the installed capacity of wind farms, have contributed about 7% of the total job count in 2020 and will make up about 12% in 2025, the analysts said.
But, with a rapid increase in offshore wind installed capacity, O&M will gain a larger share of the total jobs.
C&D roles will still dominate, however, because a typical offshore wind farm spends 60-70% of its capex in the lead-up to its commissioning, which takes between one and three years, they added.
C&D roles related to manufacturing – turbines, cables, substations and foundations – contribute about 66% of the total potential, while installation jobs account for 10% and project development for 4%. O&M adds a 20% share to the total jobs potential.
By 2030, turbine manufacturing will continue to create most of the jobs, accounting for 54% of the total.
Meanwhile, foundation manufacturing contributes 8% of the total jobs in 2030, followed by foundation installation with 5%, potentially leading to major employment opportunities.
Rystad Energy said that Europe, Asia outside of China, and the Americas will drive the global jobs creation in the offshore wind sector.
Europe, which dominates the offshore wind installed capacity globally, could expect to see demand for jobs more than triple by 2030, from 110,000 jobs in 2020 to around 350,000.
Asia, excluding China, will see a major jobs boost, most noticeable in the second half of this decade, as South Korea, Vietnam, Japan and Taiwan are expected to contribute significant offshore wind capacity.
China, meanwhile, could see demand for jobs stagnate towards 2030, despite the current activity ramp-up.
In the Americas, the US will be a major driver for offshore wind deployment because of the ambitious plans to decarbonise the power sector by 50% by 2030 put forward by the current Democratic administration.
“We estimate that the US will have almost 15GW of offshore wind installed capacity by 2030, with 30% coming from recent solicitations held by New York State,” Rystad said.
“As we move towards 2030, demand for jobs is expected to be lifted further by other countries in the region, especially Brazil, which has several large projects expected to be commissioned around the turn of the decade,” it added.
Rystad Energy product manager for offshore wind Alexander Flotre said: “Oil and gas workers will also benefit from this expected growth in offshore wind employment globally, as they share some skills sets and essential offshore knowledge.
“Offshore wind areas such as foundation manufacturing, offshore construction, project development, and O&M have been highly relevant to oil and gas operations.”
