1 TRANSITION JOINT BAYS AND JOINTING PITS

1.1 Introduction

1.1.1 This clarification note has been prepared in respect of the application for a

development consent order (DCO) to the Secretary of State under the Planning Act

2008 (‘the Application’) by SMart Wind Ltd on behalf of Optimus Wind Limited and

Breesea Limited (the ‘Applicant’) for the Hornsea Project Two Offshore Wind Farm

(‘the Project’).

1.1.2 This note is to provide clarification on the terminology used to describe the Transition

Joint Bays and Jointing Pits, the dimensions and numbers of these structures and

the details of the reinstatement of the Transition Joint Bays that have been assessed

in the Hornsea Project Two Environmental Statement (ES) (SMartWind, January

2015).

1.2 Terminology used within the ES

Project Description

1.2.1 The terminology used to describe the structure in which the offshore export cables

connect to the onshore cables in the ES Volume 1, Chapter 3: Project Description

(PINS Doc Ref No. 7.1.3) is a Transition Joint Bay.

1.2.2 The terminology used to describe the structure in which one length of onshore cable

is joined to another length of onshore cable in the ES Volume 1, Chapter 3: Project

Description (PINS Doc Ref No. 7.1.3) is a Jointing Pit.

Onshore ES Chapters

1.2.3 Some of the onshore chapters (ES Volume 3 – Onshore) refer to these structures

using different terminology, this has been identified in the paragraphs below.

1.2.4 Volume 3, Chapter 1: Geology and Ground Conditions (PINS Doc Ref No. 7.3.1)

refers to the Transition Joint Bays as Transition Pits.

1.2.5 Volume 3, Chapter 2: Hydrology and Flood Risk (PINS Doc Ref No. 7.3.2) refers to

the Jointing Pits as Transition Jointing Pits, Jointing Bays or Transition Jointing

Bays.

1.2.6 Volume 3, Chapter 3: Ecology and Nature Conservation (PINS Doc Ref No. 7.3.3)

refers to the Transition Joint Bays as Transition Jointing Pits.

1.2.7 Volume 3, Chapter 6: Historic Environment (PINS Doc Ref No. 7.3.6) refers to the

Transition Joint Bays as Transition Bays and the Jointing Pits as Jointing Bays.

1.2.8 The authors of these chapters have all confirmed that they have assessed the

correct structures, despite the different terminology used.

1.3 Numbers and dimensions of the Transition Joint Bays assessed within the ES

Project Description

1.3.1 The numbers and depth of the Transition Joint Bays given in the ES Volume 1,

Chapter 3: Project Description (PINS Doc Ref No. 7.1.3) are up to eight no. each

with a maximum depth of 6 m.

Onshore ES Chapters

1.3.2 Two onshore chapters (ES Volume 3 – Onshore) give different numbers and depths,

to those of the Project Description. This has been identified in the paragraphs below.

1.3.3 Volume 3, Chapter 1: Geology and Ground Conditions (PINS Doc Ref No. 7.3.1)

refers to four Transition Joint Bays (in the chapter these are called Transition Pits,

see paragraph 1.2.4 of this Clarification Note) with a depth of 2.5 m.

1.3.4 Volume 3, Chapter 6: Historic Environment (PINS Doc Ref No. 7.3.6) refers to the

Transition Joint Bays (in the chapter these are called Transition Bays, see

paragraph 1.2.7 of the Clarification Note) with a depth of 2.5 m.

1.3.5 The authors of these chapters have confirmed that the correct number and depths

of the Transition Joint Bays, as stated in the Project Description, have been

assessed.

1.4 Reinstatement of the Transition Joint Bays

Project Description

1.4.1 The reinstatement of land over the Transition Joint Bays once construction has been

completed given in ES Volume 1, Chapter 3: Project Description (PINS Doc Ref No.

7.1.3) is described in paragraph 3.3.57 as to be “reinstated to the original ground

level with excess material removed from site.”

Onshore ES Chapters

1.4.2 Volume 3, Chapter 2: Hydrology and Flood Risk (PINS Doc Ref No. 7.3.2) describes

the reinstatement as being “reinstated for agricultural use.”

1.4.3 The author of this chapter has confirmed that the correct description of the

reinstatement of land over the Transition Joint Bays, as stated in the Project has

been assessed.

1.5 Conclusions

1.5.1 The authors, of the above mentioned chapters, have considered the terminology,

the numbers and dimensions as well as the reinstatement of the Transition Joint

Bays and Jointing Pits, as described in the Project Description and have confirmed

that despite some incorrect references in the relevant chapters the worst case, as

described in the Project Description, has in all cases been assessed and the

significance of effect, as described in the relevant ES chapters, remains the same.
