Case Studies
Isle of Man King Edward Pier repairs for McLaughlin & Harvey
This project supported the upgrade and refurbishment of the marine civil works at King Edward VIII Pier which is situated in Douglas Harbour, Isle of Man. The pier forms Berth No.5 within the harbour and is used by the Isle of Man Steam Packet Company (IOMSPCO) for ferry services to Liverpool and Heysham.
The project provided enabling works for the new ferry to use the existing berth, and Leask Marine was contracted to preform Quay Wall Repairs and Scour Protection with their dive team.
All Project, HSEQ, pre-operations Management considered the work around ferry & harbour services works, and involved quay wall repairs, scour protection, removal of all loose material and debris from voids, drilling and anchoring reinforcement bars, anchor bolting a permanent steel facing plates, full concrete infill of the void, rock bag placement across multiple locations and producing a fill decommissioning report.
Diver Supported Cable cleaning & Bend Stiffener Installation for London Array OWF
Between the seasons of 2020 and 2022 inclusive the Leask Marine dive teams supported London Array Offshore Wind Farm with Cable Protection Systems and cleaning & adding Dynamic Bend Stiffener Installation Works.
The project Scope of Work entailed the pre-place 4-point mooring clump weights for the dive support vessels, the dDiver cleaning of J-tube bell mouth upper surfaces, the diver cleaning of Cable Protection System catenary from the buried end towards the J-tube entry to allow for bend stiffener installation, lifting, installation, and final assembly of Dynamic Bend Stiffening clamps around the existing power Cable Protection Systems at the J-tube entry with diver support. Then the calibration and torquing of Dynamic Bend Stiffener installation clamping mechanisms by the divers, and securing of Instrumentation to the J-tube and placing of terminations on various points on the platform.
This was then completed by in-water post works surveys.
Leask Marine won a three year £3m cathodic protection project through a competitive tender contract for Orkney Islands Council. This involved implementing cathodic protection and pile repairs across 17 harbours over 8 of Orkney’s Islands.
Word involved our dive team surveying steel piles (replacing them where necessary) and the installation of over 5000 anodes.
Leask Marine won a contract with McLaughlin & Harvey over three years to attach cathodic protection and fenders to the new Teesport major deepwater complex which is now one of the largest container ports in the North of England.
The Leask Marine team travelled from Orkney to complete each phase of the in-water works on site, performing these works intermittently over the three years of the construction project.
