Description

National Grid is an international Electricity and Gas Network Company based in the UK, with operations in north-eastern US. And one of the largest investor-owned energy companies in the world. National Grid are looking to set up a multi-year Marine Survey Framework to service offshore cable laying as part of the Great Grid Upgrade and may be utilised in the future for any Hydrogen Pipeline projects as applicable. The Framework will cover the full gamut of survey disciplines required for cable lay and subsequent maintenance. Including Geophysical, Geotechnical, Environmental, Intertidal/landing, Unexploded Ordinance, Maintenance with flexibility to award Turnkey requirements. The Framework is seen as being an important part of National Grid's maritime requirements to allow for a more rapid contracting of surveys potentially in parallel with other project elements that traditionally have been programmed sequentially. All data and associated metadata resulting from these surveys will be required to fall in line with relevant UK and international standards such as IHO S44, EUNIS and MEDIN to enable data archiving and sharing as required. Page 4 to 37 National Grid has committed in our Climate Transition Plan to achieve close to zero emissions by 2050 and science based intermediary targets aligned to a 1.5 degree pathway for our UK Electricity Transmission, System Operator and Distribution businesses. To achieve this ambitious target, we need to ensure all our suppliers are on a similar path and this Framework will look to leverage novel and autonomous technologies to achieve this. The Framework will look to incentivise companies on the Framework to reduce the project footprint where possible. All projects will also require the companies to provide accurate carbon footprint reporting.
