Current Projects

Over the years the port has changed significantly with the focus on addressing the needs of the evolving client base and providing infrastructure for support companies to expand their services and grow.

As part of the ambitious programme of port infrastructure development there will be various submissions to regulatory bodies during the project life cycle. We will endeavor to publish these submissions at the earliest opportunity so that stakeholders and interested parties can access them.

To ensure that correct information is supplied we may provide links to the Regulatory bodies systems where appropriate.

 

Project: Redevelopment of the St Ola Pier

Project Summary Boards

Current Status: Application Submission

Introduction:

Scrabster Harbour Trust have applied to the Scottish Ministers for marine licences under section 20 of the Marine (Scotland) Act 2010 to expand the existing St. Ola Pier and undertake dredging at Scrabster Harbour.  The marine licence applications are accompanied by an Environmental Impact Assessment Report (EIAR).

The project is summarised below – the marine licence applications, EIAR and design drawings can be viewed in full, online at http://marine.gov.scot/ml/st-ola-pier-redevelopment-scrabster

Any representations should be made in writing to the consenting authority by email to: ms.marinelicensing@gov.scot or by post to The Scottish Government, Marine Scotland Licensing Operations Team, Marine Laboratory, 375 Victoria Road, Aberdeen, AB11 9DB, identifying the proposed works and specifying grounds for objection or support, not later than Sunday 17th November 2019.

Project Summary:

The existing St. Ola Pier was constructed in 1972 and has fallen into declining use due to ongoing corrosion of steel piling and lack of load bearing capacity for imposed deck loads. The existing Pier is situated within the centre of the harbour and incorporates a 100 metre long berth to the south-west, a linkspan and a further 115 metre berth which was used by the Orkney Ferry prior to the Queen Elizabeth Pier being constructed in 2003.

The opportunity afforded by redevelopment is being used to provide an enhanced straight berthing face on the inner side for service and cargo vessels with a new berth on the outside face; particularly for cruise vessels of up to 250m long.

The pier will be widened locally to accommodate straight berthing faces with resulting parallel berthing faces at approximately 32m apart.

Partial demolition of the existing pier will be required to allow for the construction of the new pier walls and decking. Pier quay walls will likely comprise steel tubular piles with interlocking steel sheet piles. It is proposed that any concrete broken out as part of the demolition works will be crushed to allow for reuse within the works, as engineering fill (subject to meeting performance criteria).

The renovated pier will be circa. 280m long and fully enclosed around the perimeter. An enclosed structure will allow for beneficial reuse of both dredge spoil and crushed recycled concrete if suitable. There will be a concrete deck with drainage captured through full retention interceptors as well as a number of centrally positioned lighting masts capable of providing 50 lux.

The outer face will be dredged to provide a depth of -9m CD to accommodate cruise vessels and the inner face will be dredged to provide a consistent berth depth of -7.5m CD.

The works may also include for reclamation and revetment of 0.84ha (plan area of both) at the root of the pier. The reclamation area will provide storage space for cargo handling, and may house a number of fuel tank(s) in the future which will allow for the refueling of vessels on St. Ola Pier. The reclaimed area would reuse the rock armour from the existing revetment on the newly reclaimed seaward face with a small additional requirement for extra rock armouring.

The volume of dredge material generated by the works is approximately 172,000m3 of sandy gravel and clay. It is proposed that dredge material will be re-used within the reclaimed area and within the redeveloped pier structure (if deemed suitable by the works contractor). Alternatively dredge spoil may be disposed at a sea disposal site indicated in Best Practicable Environmental Option (BPEO) Report, Appendix 2.1, Volume II of the EIAR; or disposed at a licenced waste facility on land and off-site; or a combination of these solutions (subject to Contractor’s chosen methodology).  For the purposes of environmental assessment of the marine environment, it is assumed that the total volume of dredged material generated by these works (172,000m3) shall be disposed at sea in the Scrabster dump site.  For the purposes of traffic assessment, an additional scenario has been assumed whereby all of the dredged material is transported off site by road during the construction period.

Notwithstanding the above assumptions for the purposes of environmental assessment, the Design & Build tender will include a requirement that the detailed design will accommodate as much reuse of dredged material into the reclamation areas and into the body of the pier as is economically feasible.

A water and fuel supply will be provided on the St. Ola Pier. The fuel pipe will either be routed from the existing supply on the Jubilee Pier, or from a new tank(s) proposed for the reclamation area.  All services will be buried within the pier and located within a covered trench which will allow for maintenance and access.  3 nr export (bunkering) points are proposed on each berth, with 1 nr fuel import point on each berth.

The works will require service connections to allow for power and water to service the redeveloped pier. A minimum 400V shore power supply will be provided from the existing transformer located behind St. Ola Pier on the shore-side. A number of high mast lights will be provided to ensure adequate working light for all activities.
