Dales Marine Services Drydocking News

Dales Marine Services continue to set the pace for efficient vessel drydocking, and this well demonstrated not only by recent activity, but also with the impressive 24 confirmed bookings made by ferry operator Caledonian MacBrayne for the forthcoming season – typically running from September to April. Most of the CalMac vessels in this annual refit programme will be docked at Dales Marine’s dry docks at Greenock or Troon on west coast of Scotland, with 2 vessels using Dales Marine’s dry docks on east coast – Aberdeen Leith.

Since forming in 1987 the Company’s services have of course been enjoyed by many of the vessel owners/operators servicing the offshore energy sector, and in this sector Dales Marine have reached out to clients working across the whole of the North Sea basin, and to those clients working in the more recently developed areas such as West of Shetland .

Such is Dales Marine’s capability and reach, that it continues to attract new business from other marine sectors, and is already making a big impression on the aquaculture sector where impressive fleets of modern well boats are now operating. These, now technologically advance well boats, are used to transport live fish in modern fish‑farming, both out to the sea-cages, and from the cages to the processing plants. Dales Marine’s clients in this sector are mainly Norwegian based with international operations – another testament to Dales Marine’s capability and reach.

One recent example of this is service and repair work carried out for their Norwegian client Solvtrans on Ronja Commander - a well boat designed for live fish transportation. This vessel initially docked at Dales Marine Troon for hull cleaning and painting, and then to wet berth at Dales Greenock for various works including stainless steel cargo pipe modifications, steelwork repairs, hydraulic works, and for electronic navigation equipment- survey and repairs.

Looking to near term future, Dales Marine Services are confident of expanding their reach further. Their drydock facilities are well‑placed for this, and recent activity in period to mid-July includes:
