Vessel Emission Control

The request was successful.

Dear Maritime and Coastguard Agency,

The River Thames along with the North Sea and English Channel now has a Nitrogen Emission Control Area (NECA). The North Sea NECA requires vessels laid down/built post January 2021 to comply with the restriction.

The Oceandiva is a new vessel that is soon to be operating on the River Thames and powered by electric motors drawing power from a significant amount of lithium iron batteries.

There is also a 'back up' diesel generator allegedly for use in an emergency.

Will this diesel generator be required to meet IMO Tier III emissions standards, regardless of the fuel being burned?

If a diesel generator is claimed to be used for emergency purposes, can it avoid meeting the IMO Tier III requirement?

Below what power output, from a diesel generator on a vessel being used to charge batteries or for emergency services would not be required to comply with IMO Tier III?

Yours faithfully,

Ralph Hardwick
