The Local Supply Market

Whitby Harbour

Harbour Facilities

• Up to 3000 tonnes DWT

• IOA – 85 metres

• Beam 14 metres

• Draft 5 to 6.5 metres (subject to tide)

Education Provision

Preparing the employees of the future

• Whitby Harbour at South Shields

• A. world class Marine Simulation Department containing two 360 degree full-mission bridges and 12 other integrated bridges.

• B. An integrated full-mission engine room and associated engine workstation rooms. The Department also houses an extensive VTS simulator system and fully equipped Navigation Aid Laboratory

Education ProvisionPreparing the

employees of the

future

• 6th Form Colleges

• University of Hull

• Whitby and District

Fishing Industry

Training School

Local Suppliers

• Skyclimber of Pickering

• designs, manufactures, installs and

maintains service lifts to allow quick, safe

and reliable access to the internal parts of

the wind turbine

Parkol Marine• Parkol Marine in Whitby offers a dry dock for all boat building requirements.

• The Dry dock offers a 5m draught and can accommodate vessels up to 42 m in length with a 10.5m beam

• An on site lift can manoeuvre vessels of up to 450 tons

Current Strategy• Raise Awareness:

– Liaison with Venn Management – a Yorkshire Forward Company (IA/JR)

– Attendance at Forewind Event and raising with industry(IA)

– Develop Logo (see below)

– Take stand at Renewables UK National event (NTaylor/Martin Willis)

– Establish Local Supplier Network (Whitby and Scarborough Off Shore Wind)

– Run Regional Stakeholder Event at Whitby Pavillion with National Speakers – 23 July 2010

– Create Brochure – Created, to go to print when appropriate advertising in place

– Place Newspaper articles (Yorkshire Post/SEN/National Media)

• Identify gaps in supply that need to be addressed– Professor Hardisty, University of Hull

– Visit to Grimsby Docks (currently involved with Phase 1)

• Maintain Information Supply– Create Website: www.whitbywind.co.uk

• Establish Whitby Harbour Pilot Board with requisite skills– Promoting the Board opportunity to possible Board members

– High Quality applicants

• Consider Partnership with Private Sector Provider– Tender opportunity

Future Challenge for major ports

• Changing Industry Requirements

Changing Industry requirements:

• Project logistics are changing…

• Likely development of ‘Super Logistics’

ports that are used to:

– feed many projects in a region

– Reduce need for project specific local ports

• Local ports only used for shelter and

resupply
