If you are UK resident, you would need to declare your worldwide earnings through self-assessment but you would have the potential to claim Seafarers Earnings Deduction to reduce or eliminate your liability for tax

If your daughter qualifies for SED, her income from November 23 to April 2024 would be covered by the allowance. Any other income from April 2023 to the start of the claim would remain taxable, and this tax would be payable by January 2025.

In reality though, if you put the relevant figures on the tax return, no High Income Charge is applied if enough SED is claimed to reduce taxable income to below £50k.
