This Part of this Schedule sets out special rules that apply where a qualifying ship operated by a tonnage tax company is engaged in offshore activities.

The rules in this Part of this Schedule do not apply in an accounting period unless the total number of days in that period on which qualifying ships operated by that company are engaged in offshore activities exceeds 30.

In this Part of this Schedule “offshore activities” means activities in connection with the exploration or exploitation of so much of the seabed or subsoil or their natural resources as is situated in the UK sector of the continental shelf.

The Treasury may make provision by order excluding other kinds of vessel from the application of the provisions of this Part of this Schedule.

The profits of a tonnage tax company from a qualifying ship in respect of periods during which the ship is engaged in offshore activities (its “offshore profits”) are computed and charged to tax in accordance with ordinary corporation tax principles as if they were not part of the company’s relevant shipping profits.

Accordingly, the number of days in an accounting period during which a qualifying ship is so engaged shall be left out of account for the purposes of paragraph 4 (calculation of tonnage tax profits by reference to daily profit).

The provisions of Part VII (the ring fence: general provisions) apply in relation to a company’s offshore activities as if they were not tonnage tax activities.

The provisions of this Schedule apply in relation to a company’s offshore profits as they apply to profits other than relevant shipping profits.

A tonnage tax company may claim capital allowances for capital expenditure incurred in providing plant or machinery for the purposes of its offshore activities.

The amount of the notional qualifying expenditure is given by paragraph 112 (existing assets) or paragraph 113 (new assets).

Where an asset to which this paragraph applies ceases permanently to be used for the purposes of the company’s offshore activities, it is treated for the purposes of F2Part 2 of the Capital Allowances Act 2001 as it applies by virtue of this paragraph as if it had been disposed of at market value.

This does not apply if a disposal value is required to be brought into account under F3section 61(1) of that Act apart from this sub-paragraph.

This paragraph applies where in an accounting period of the company an asset to which paragraph 110 applies is used for the purposes of the company’s offshore activities on some only of the days in the period.

The amount of any writing-down allowance for that period in respect of expenditure incurred on the provision of the asset is restricted to the relevant proportion of the full allowance.

Any writing-down allowance for a subsequent accounting period of the company in respect of such expenditure shall be calculated as if an allowance had been made of an amount equal to the full allowance, whether or not that amount (or any amount) was in fact claimed.

For the purposes of this paragraph the full allowance means the allowance (if any) that would have been available apart from this paragraph.

For the purposes of this paragraph the relevant proportion of the full allowance is given by:

OSDAPD

This paragraph applies to determine the amount of notional qualifying expenditure for the purposes of paragraph 110 where the company was entitled before entry into tonnage tax to capital allowances in respect of expenditure on providing the asset.

If the asset was brought into use for the purposes of the company’s offshore activities immediately on entry into tonnage tax, the notional qualifying expenditure is equal to any unrelieved qualifying expenditure attributable to the asset.

In this paragraph “unrelieved qualifying expenditure” means the unrelieved qualifying expenditure that would otherwise have been carried forward under Chapter 5 of Part 2 of the Capital Allowances Act 2001.

The amount of unrelieved qualifying expenditure attributable to plant or machinery in a class pool, or the main pool, is the proportion of the whole given by:

AVPV

References in this paragraph to unrelieved qualifying expenditure include qualifying expenditure to the extent to which it is unrelieved by virtue of notice having been given under F5section 130 of the Capital Allowances Act 2001 (notice postponing first-year or writing-down allowance)—

If the asset was not brought into use for the purposes of the company’s offshore activities immediately on entry into tonnage tax, the notional qualifying expenditure is the amount given by sub-paragraph (2) but written down in respect of the period between the company’s entry into tonnage tax and the asset being brought into use for those purposes.

The Inland Revenue shall make provision by regulations as to the basis on which the writing down mentioned in sub-paragraph (6) is to be done.

The regulations may make different provision for different descriptions of asset.

This paragraph applies to determine the amount of notional qualifying expenditure for the purposes of paragraph 110 where the company was not entitled before entry into tonnage tax to capital allowances in respect of expenditure on providing the asset.

If the asset was brought into use for the purposes of the company’s offshore activities immediately on being acquired by the company, the notional qualifying expenditure is equal to the amount that would fall to be brought into account as qualifying expenditure under F6Part 2 of the Capital Allowances Act 2001 apart from this Schedule.

If the asset was not brought into use for the purposes of the company’s offshore activities immediately on being acquired by the company, the notional qualifying expenditure is the amount referred to in sub-paragraph (2) written down in respect of the period between its acquisition by the company and its being brought into use for those purposes.

The Inland Revenue shall make provision by regulations as to the basis on which the writing down mentioned in sub-paragraph (3) is to be done.

The regulations may make different provision for different descriptions of asset.

The fact that a qualifying ship is used for the purposes of offshore activities does not affect the training requirement but an allowance is made under this paragraph.

The amount of the allowance may be deducted by the company in computing the amount of corporation tax payable for that accounting period, so far as that is attributable to offshore activities.

No deduction may be made by a company in computing its profits from offshore activities in respect of expenditure incurred in meeting the training requirement.
