Industrial Cleaning at BAE Scotstoun

Client: BAE Systems

Location: HMNB Portsmouth and Scotstoun

Project: New build offshore patrol vessels (OPV)

Service: Industrial cleaning



Denholm Industrial Services (DIS) secured the provision of multi-discipline services in support of six new build vessels for BAE Systems. One of the key trades was General and Final Inspection (FI) cleaning.

The project spanned six years and resulted in Denholm travelling with the ships built at Portsmouth, Tyneside and Glasgow.


The Challenge

The warship building process requires many skilled operatives working thousands of manhours and in the process considerable quantities of waste are produced. BAE Systems needed a service provider that could maintain cleanliness on board the ships throughout their build to avoid a potentially dangerous accumulation of trade waste.  In addition and nearing build completion, BAE Systems required all compartments to be deep cleaned prior to final inspection by their customer, The Royal Navy.

These works were to be completed in a congested and high risk environment while maintaining the highest standards of safety and quality.


The Solution

Working collaboratively with BAE Systems, Denholm Industrial Services developed a cleaning strategy to ensure that regardless of ongoing works, the in-build ships were patrolled and cleaned by a dedicated team.  It was necessary to provide a flexible service to accommodate the peaks and troughs in the build programme, which resulted in a dedicated cleaning team fluctuating between 60 and 120 operatives. The team removed all trade waste from the vessels and, after segregation, placed the waste in the appropriate receptacle for onward disposal or recycling.

Included in our team was a specialist inspection squad to ensure we consistently met the high demands of the client’s inspectors onsite.



The project was executed well to the satisfaction of our client and their customer.
