"Thank you for the works completed at Bradwell on Saturday. The report back from our team is that you did a really great job, not only in finding and attaching the frame, but also in the general approach to the works. It makes all the difference to us to have such reliable and professional support. We do not often use diving support, unless something has gone wrong. In such instances, we will definitely come back to you as our first choice. Thanks again to you and your team. "

MMC Diving Services have done a wonderful job at Cog Moors WwTW, the job posed difficult challenges of which the team has met with enthusiasm and professionalism I have rarely seen. The team were knowledgeable and extremely helpful with a can do attitude.

Sam and the MMC team have been completely honest and transparent with regards to any and all costs relating to the job. The safety commitment from the team was exceptional, the Risk assessments and Method statements and all paperwork was of a high standard, reports and daily logs etc. were sent out daily on time without exception. An excellent company which I cannot wait to work with again.

"MMC were more than satisfactory as a diving contractor, working very closely with us on the Cowes RNLI slipway project, I was particularly impressed with how easily they proved there competency to the HSE during a spot diving inspection by two of the HSE diving Inspectors. We would have no hesitation in recommending MMC Diving Services for further works"

"Always a pleasure to work with Sam and the team when they are on the premises. I would definitely recommend them to our clients."

Ben Ferris
Marina Development Manager Cowes Yacht Haven

"The job started off as one day dive/inspection but quickly developed into several days involving a crane barge to remove some large pieces of debris from the end of the Slipway. MMC attended at short notice and remained on the job, working with weather and tides until we have achieved the objective that developed during the first couple of days. The costs were the industry norm and the personnel were very helpful and cooperative in working with an operational Lifeboat Station."

"Cowes Harbour Commission, Kingston Marine Services and MMC divers are a well proven combination. The wreck removal of the sunken MV on the river Medina this November is the latest in a succession of very successful projects."

"We would like to express our thanks to everybody that was involved with the clearance under the bridge in Wroxall high street.

The week previously it was high pressure jetted and although this improved the flow considerably, it was the divers that climbed into the small space and manually cleared out the culvert. We are all really impressed with the lengths island roads and their team have gone to to resolve the problem. It's now flowing very well indeed, we have access back to our properties and have noticed fish back in the stream."

"I was very satisfied with the professional attitude and quality of service offered by your guys. Especially given the challenging site conditions."

Ruth Crewe

"It has been my pleasure to work with the team at MMC throughout my four years as Marine Services Manager for the Cowes Harbour Commission.

This has been on routine maintenance in association with harbour assets, such as Trinity Landing and marina pontoons, as well as incident based deployments such as small boat salvage and recent dive support during the successful salvage of the motor vessel 'Kahu'.

MMC are always willing to be there and get on, there is never a reluctance to get involved, and if the occasion demands it to bring innovative thinking to the situation. I have found them to be an efficient, enthusiastic and above all, safe organisation and look forward to working with them again in the future."
