Subsea Crossings Inspection

Marine inspection for subsea crossings between Outer Hebrides and West Cost Scotland for Scottish Water. Utilising a variety of techniques and equipment from Sonar, ROV, Subsea Cameras and qualified Divers.


Inspectahire were tasked with carrying out inspections on subsea crossings between the mainland West Coast of Scotland and the Outer Hebrides on behalf of Scottish Water to assess the integrity of the assets and any maintenance required.

These crossings carry fresh water between the island chain and provide a vital service to the islands’ inhabitants.


Using market-leading equipment and proven inspection techniques Inspectahire’s experienced personnel began on the Isle of Lewis and over the next two months provided a high level of asset integnity inspections on ten crossings between the islands and further down the mainland West Coast efficiently and accurately.

The first stage was Sonar/Geo-mapping inspection to give the first indication of the condition of the crossings.

This was followed by a 100% visual inspection carried out using subsea cameras, Remote Operated Vehicles (ROVs) with Crawler Skid Attachments (CSAs).

A number of diving inspections were also carried out on the crossing by Inspectahire’s team of in-house divers and equipment supported by Puffin Dive Centre from Oban.

All diving was carried out by qualified HSE Scuba divers complying with the HSE Approved Code of Practice for in-shore diving.

Sonar, ROV and Diving Operations were carried out from Inspectahire’s RIB Moray Gig.


Inspectahire’s multi disciplined team carried out all ten inspections on time and budget with great results for the client.
