Who we are
E.D.S is a well established marine contractor.
We are underwater engineers, confined space
and marine pollution specialists and pride ourselves
on being able to offer the
technical base, resources and expertise to
provide a high quality, safety conscious and
cost effective service.
We are members of the Association of Diving
Contractors, approved contractors to the
Ministry of Defence, various Utility companies
and are members of Constructionline.
E.D.S has practical experience in all aspects
of marine engineering, whether it is from a boat
or on the seabed we cover all aspects of our
industry.
We offer a wide range of services not just
diving, but mechanical engineering facilities,
coded welders, explosive advice, marine and
civil engineering.
Our equipment register is extensive with
numerous underwater cameras, a highly
capable ROV, ultrasonic thickness monitors,
welding and burning equipment, various boats
and rescue craft.
We have also partnered up with a number of
specialist consultancies for cathodic protection,
structural or diving surveys and have no limits
to where we travel.
Civil Engineering
Pumping concrete underwater is certainly not a new concept, it is however accepted as a solution to a lot of engineering issues which would have only previously been carried out in the dry, concrete actually sets better underwater and with modular formwork seen in the photograph below can be constructed in varying shapes and sizes.
EDS has experience in a number of Civil Engineering projects, as the Principal Contractor or working as Consultants. We have worked on a wide variety of projects including barrages, reservoirs, water intakes, power stations and hydro electric installations.

We have carried out various land drainage repairs for many different local authorities throughout the UK, the illustration here shows an invert being repaired with a fresh concrete pour of 6m3 about to be pumped over the steel reinforcing mesh. On this occassion the culvert was dammed with the water being pumped over reducing the risk of polluting the watercourse and washout with the fast flowing water that had caused the damage in the first instance.

Power stations use an incredible ammount of water, both in and out of the power station, we have carried out numerous works sealing old intakes from decommisioned sections of the cooling water inlets and outlets to carrying out running repairs on the structural Integrity of a working cw system. We have carried out civil works on nuclear, coal, gas and hydro electric stations.

Whilst carrying out a routine inspection of a reservoir for a steelworks one of our diving engineers discovered a large void, which if not repaired very quickly was going to empty the reservoir with catastrophic effect, with some adjustment to our working schedule we carried out immediate repairs and poured 15m3 into the void and reinforced the area underwater and then stregthened all of the vulnerable areas once the situation had been stabilised.
Capping some redundant cast iron pipes underwater to a reservoir is usually straight forward enough, high in the mid Wales mountains with a single track road 5 miles from the main carriageway was always going to make it more of a challenge, which proved to be the case at Rheidol reservoir near Aberystwyth. We had to bring all of the raw materials up by tractor and 4 x 4 vehicles, 20 x 1 tonnes bags, which was pumped with an "upgraded" grout pump 30m deep into the redundant pipes.
