MARINE ASSET MANAGEMENT PLAN – UPDATE 2.0 INTRODUCTION 2.1 This report provides Members with an update on ongoing major,
and/or noteworthy, schemes currently being addressed within the Council’s Marine Asset Management Plan.
3.0 RECOMMENDATIONS
3.1 Members are asked to:- a) note this report and, in particular, the progress achieved to date on those schemes highlighted within this report and, b) approve the revised version of the 10 year asset management plan in the appendix to this report – Revision E.
4.0 BACKGROUND
4.0 A report was presented to the Harbour Board in January 2018 which provided details of major schemes being programmed within the Marine Asset Management Plan at that time; this report provides Members with a further update. In order to fund the various works identified in the Asset Management Plan in future years, it will be necessary to review fees and charges on an annual basis to ensure necessary funding is available for identified works.
4.1 As Members are aware, Council officers meet regularly with
representatives from Transport Scotland, Calmac and CMAL to discuss future plans for the Council’s marine assets; priorities are set by the Council on the basis of these discussions.
4.2 Main priorities agreed with Transport Scotland, CMAL and
Calmac remain as follows:-
• Iona and Fionnphort – Provision of breakwater and overnight berth respectively.
• Mull / Craignure Pier – Upgrade infrastructure.
4.3 This report provides Members with an update on a range of schemes.
5.0 DETAIL - The Asset Management Plan:-
5.1 The Asset Management Plan lists the likely work to be carried
out over the next 10 years across the entire marine infrastructure; it also provides indicative budgets – see Appendix A. Currently the overall costs for planned works is in excess of £90 million – this includes an estimated figure for potential works at Craignure Pier on Mull. Further detail is provided below for some of the more major, or noteworthy, schemes. Capital works programmed for this financial year total £4.627 million. A number of schemes have been added to the plan as a result of information received from last year’s principal surveys; these latest schemes include remedial works at Craighouse on Jura and the South Pier on Gigha where concrete works are required; in addition, cathodic protection will be installed at Port Askaig, Carradale and West Loch near Tarbert to protect sheet piles. To ensure this year’s capital budget is not over-spent, the next phase of the works at Rothesay – grouting – will be phased to adjust overall capital spend.
5.2 Craignure Pier:-
Since the last meeting of the Harbour Board, the STAG report has now been completed. The report considers a number of costed options for replacement of the pier and for the interim phase until replacement – Costs are attached in Appendix B of this report. A separate report will be presented to the September 2019 Harbour Board. A Craignure Port User group has been established and Terms of Reference agreed. These meetings to be chaired by an elected Member of the Council.
5.3 Helensburgh Pier:-
5.3.1 With the assistance of the Helensburgh Seafront Development Project (HSDP), liaison continues with Waverley Excursions to consider wether it is possible to identify affordable options to allow berthing of the Waverley at the pier. Options which have been given some consideration are as follows:-
• Major repairs to the timber pier to reinstate all
damaged sections - essentially, all damaged timbers would be replaced on a like-for-like basis, including timbers in the fire-damaged area. Costs for this option are likely to be in the region of £850K.
• Construct new berthing structure (monolithic piles with fendering system) adjacent to the pier and connected by an access gangway - this option would allow the Waverley to berth. Costs are likely to be in the region of £580K for this option.
• Dredging - a further option would involve berthing the
Waverley to the west side of the pier and dredging a new channel to accommodate the approach to the pier; this option would involve less work on the pier itself. A cost estimate for related works is currently
being produced – however, latest indications are that initial capital dredging costs could be significant and this option would require regular expenditure of the Piers and Harbours revenue budget to ensure that channel depths were maintained.
5.3.2 Members should be aware that funding for any of the
options has not, as yet, been identified and that no income is generated at this pier.
5.3.3 In the meantime, in the interests of public safety, £85,000
of ‘town-centre’ funding has been allocated to make the pier safer for pedestrian use – particularly given that the pier is, for the time-being, not functioning as a vessel berthing facility. Design work will be carried out in-house with a view to issuing a tender for appropriate works later this year.
5.4 Rothesay Pontoons:-
5.4.1 £150,000 of town-centre funding has been allocated for replacement of pontoons at Rothesay Harbour. A plan of the pontoons is provided in Appendix C. The existing pontoons are anchored in place with concrete blocks and chains. Circular piles can be used to anchor pontoons in place, however, this is a more costly option than using anchor blocks and chains; it does, however, have the benefit of providing a more stable platform and this is likely to be more attractive to cruise ship groups. An exercise will be carried out to ascertain the likely increase in income, versus the additional cost of piling. If sufficient additional income can be generated it may be possible to fund prudential borrowing that could supplement the town centre funding. .
5.4.2 Dependent upon the design solution, Design Services will
produce tender documentation for a design / build contract with a view to having the contract in place before the end of this financial year. However, for the ‘piled option’, ground investigation works may be required – at the time of writing this report, a review of record drawings/reports was being carried out. A project programme will be produced for all phases of this project, however, it should be noted that the application for marine licences and procurement / organisation of ground investigation works will ensure that any construction programme will be significantly constrained given the limited time available prior to contract award. Contract award must be made before the end of March 2020 to comply with the Town Centre Fund conditions.
5.5 Rothesay Harbour –
Work on the wave screen is nearing completion, with works due to be complete by mid-August this year. The wave screen is considered to be the first phase in the overall work required to address continuing settlement at Rothesay Pier. Following completion of installation of the wave screen, which will reduce the risk of further settlement, further works will be required in
order to stabilise the infill material within the masonry pier; grouting work will be carried out in the forthcoming financial year. In addition to civil engineering works, a contract will be issued shortly for removal and refurbishment of all sixteen cylinders in the passenger access gangway (PAG) at Rothesay; works will be carried out overnight and, as such, no disruption to sailings is anticipated. Photographs of the wave screen and PAG are provided in Appendix D in this report.
5.6 Fionnphort / Iona Ferry Slips –
5.6.1 Byrne Looby’s feasibility report has now been issued at draft stage. This detailed report considers a number of options for the overnight berth at Fionnphort and breakwater on Iona. The layout for the preferred options is provided in Appendix E to this report.
5.6.2 The original estimate for the works, based on a report
produced by the consultant Arch Henderson in 2015, varied from circa £4 million to £31 million for both schemes - £4 million being taken as the original overall scheme estimate. Following the development of the latest favoured schemes by Byrne Looby, the updated estimates for preferred schemes at Iona and Fionnphort are £10 million and £8.3 million respectively i.e. £18.3 million in total. The berthing structure at Fionnphort and breakwater at Iona now differ significantly from that originally anticipated, with scheme types developed from information gathered through consultation with the local community and from the recently completed wave-modelling studies.
5.6.3 Dependent upon the next stages – sedimentation
modelling and final scheme design – it is anticipated that work may commence on site at Fionnphort as early as 2020 – see attached programme in Appendix E. A brief for the sedimentation study is currently out to tender. Given the increase in estimated cost for this scheme, an Outline Business Case will be produce for Member approval prior to moving to full design stage.
5.7 Oban North Pier –
Grouting work to stabilise ground at the North Pier is now complete.
5.8 Dunoon Breakwater –
A contract to address settling rock armour at Dunoon breakwater was awarded to the Contractor L.M. Keating on 23 August 2019 – value £812K. The contractor’s programme is awaited. A photograph of the rock armour and Dunoon breakwater is attached in Appendix F. Transport Scotland have agreed to host an officer working group to consider port side infrastructure for the Gourock to Dunoon
service. Updates on the work of this group will be brought to the Harbour Board.
5.9 Link-Spans –
A tender was issued in mid-2018 to seek the services of a Mechanical Engineer with specialist link-span experience. A specialist engineer, seconded from the consultant ‘Royal Haskoning’, has been working directly for Marine Services since the beginning of this calendar year. A complete review has been carried out on all Council link-spans – at Dunoon, Rothesay, Campbeltown, Port Askaig and Craignure – this has taken the form of on-site inspections, reviews of maintenance records – both specialist and on-site maintenance – along with a complete review of extant link-span maintenance contracts. Recommendations were made to extend one of two existing contracts for a finite period with a view to re-tendering link-span maintenance in the near future. Following initial surveys and recommendations, RL Engineering, our current maintenance contractor, has completed their ‘first-round’ of servicing on all link-spans since the contract extension was signed. The opportunity was taken to replace all hydraulic hoses at all 5 link-spans during RL’s recent servicing work. Craignure link-span will require replacement of some major parts and work is ongoing to prepare for refurbishment work later this year – see photos in Appendix G. Close liaison will take place with Calmac and, of course, the local community before works are carried out. Once planned works are completed at Craignure, a tender will be issued for maintenance of link-spans – the tender document is currently at draft stage.
In addition to the above, a consultancy brief to carry out structural checks on all link-spans, was recently issued for tender purposes. Tender returns are awaited.
5.10 Campbeltown Harbour –
Sheet piling works / cathodic protection. A contract to address corrosion of sheet piling at Campbeltown Old Quay walls (C, D, E and F) has been won by the contractor ‘Lochshell Engineering’. Works are due to start this week, with an on-site survey by the contractor, followed by off-site fabrication. See Appendix H for location photograph.
