“The Intergroup team quickly met the challenges of cleaning the machinery spaces on the ex Royal New Zealand Navy Ship, RESOLUTION. The surfaces within the machinery spaces were covered in an oily film and dust. Cleaning was undertaken to bilges, machinery, deck plates, and bulkheads; and was completed ahead of time and to the required standard. Their friendly, motivated and professional staff take huge pride in their work and are a pleasure to deal with.”
