The Dogger Bank Creyke Beck Offshore Wind Farm Order 2015

Chemicals, drilling and debris

6.—(1) All chemicals used in the construction of the authorised scheme, including any chemical agents placed within any monopile or other foundation structure void, must be selected from the list of notified chemicals approved for use by the offshore oil and gas industry under the Offshore Chemicals Regulations 2002.

(2) The undertaker must ensure that any coatings and treatments are suitable for use in the marine environment and are used in accordance with guidelines approved by Health and Safety Executive or the Environment Agency pollution prevention control guidelines. Any spillages must be reported to the MMO marine pollution response team within the timeframes specified in the marine pollution contingency plan.

(3) The storage, handling, transport and use of fuels, lubricants, chemicals and other substances must be undertaken so as to prevent releases into the marine environment, including bunding of 110% of the total volume of all reservoirs and containers.

(4) The undertaker must ensure that any debris arising from the construction of the authorised scheme or temporary works placed seaward of MHWS is removed on completion of the authorised scheme.

(5) At least 10 days before commencement of the licensed activities, the undertaker must submit to the MMO an audit sheet covering all aspects of the construction of the licensed activities or any phase of them. The audit sheet must include details of—

(a) loading facilities;

(b) vessels;

(c) equipment;

(d) shipment routes;

(e) transport;

(f) working schedules; and

(g) all components and materials to be used in the construction of the authorised scheme.

(6) The audit sheet must be maintained throughout the construction of the authorised scheme (or relevant phase) and must be submitted to the MMO for review at fortnightly intervals.

(7) In the event that the MMO becomes aware that any of the materials on the audit sheet cannot be accounted for, it must require the undertaker to carry out a side-scan sonar survey to plot all obstructions across a reasonable area of search agreed with the MMO where construction works and related activities have been carried out. Representatives of the Holderness Fishing Industry Group must be invited to send a representative to be present during the survey. Any obstructions that the MMO believes to be associated with the authorised scheme must be removed at the undertaker’s expense.
