4.3. Decommissioning
4.3.1. Ossian Impact
- For decommissioning, which is expected to take place after the operation and maintenance lifespan of Ossian, it was estimated that the cost could be £542 million, of which £162 million (30%) could be secured in the UK (all of which could be secured in Scotland). It is assumed that the remaining 70% could be secured elsewhere in the world (Table 4.19).
Table 4.19: PDE Option 1: Ossian Decommissioning Spending by Category, Scotland and the UK
Parameters | Scotland | UK (Inc. Scotland) | Total (Scotland, rUK and rWorld) |
|---|---|---|---|
Wind Turbine Decommissioning | £8 m | £8 m | £26 m |
Mooring and Anchoring Decommissioning | £45 m | £45 m | £148 m |
Cable Decommissioning | £81 m | £81 m | £271 m |
OSP Decommissioning | £29 m | £29 m | £96 m |
Total | £162 m | £162 m | £542 m |
Percentage of total expenditure (%) | 30% | 30% | 100% |
- Applying turnover per employee and turnover/GVA ratios for the relevant sectors it was estimated that Ossian’s direct economic impact could be £49 million GVA and 580 years of employment in the UK, all of which could be secured in Scotland (Table 4.20).

|---|---|---|---|---|
| GVA | Jobs | GVA | Jobs |

OSP Decommissioning | £9 m | 100 | £9 m | 100 |
Total | £49 m | 580 | £49 m | 580 |
- Applying GVA and employment multipliers it was therefore estimated that Ossian’s economic impact could be £90 million GVA and 1,040 years of employment in Scotland, and £130 million GVA and 1,580 years of employment in the UK (Table 4.21) (Table 4.22).

4.3.2. Array Impact
- The decommissioning spend associated with the Array was estimated to be £174 million, of which £52 million (30%) could be secured in Scotland and the UK (Table 4.23).

Parameters | Scotland | UK (Inc. Scotland) | Total (Scotland, rUK and rWorld) |

Total | £52 m | £52 m | £174 m |
Total (%) | 30% | 30% | 100% |
- Applying turnover per employee and turnover/GVA ratios for the relevant sectors it was estimated that the Array’s direct economic impact could be £16 million GVA and 190 years of employment in Scotland and the UK (Table 4.24).

Total | £16 m | 190 | £16 m | 190 |
- Applying GVA and employment multipliers it was therefore estimated that the economic impact of decommissioning the Array could be £30 million GVA and 330 years of employment in Scotland, and £40 million GVA and 510 years of employment in the UK (Table 4.25) (Table 4.26).
