TRSubC

Design
Seabed survey, layout, choice of anchoring and sizing. You know what will be installed, where and why, before the first lift.
At three metres, the same team, the same equipment and the same preparation as at sixty-nine.
TRSubC builds and maintains pontoons and harbour structures, and inspects, repairs and installs underwater for harbours, municipalities, owners, operators and industry. We don't sell dives: we hand back a structure in working order, on a set date.
You want to build, extend or refurbish pontoons, moorings or a harbour structure. See how we design, build and maintain it.
You have an underwater structure to inspect, repair or equip. See what we do and how we prepare a job.
You want to give your clients the safety of a large organisation without being one: resources, procedures, insurance, personnel.
A harbour is built as much underwater as on the surface. We design the layout, install the pontoons and their anchoring, then maintain them season after season, with our own divers for everything below the waterline.
Seabed survey, layout, choice of anchoring and sizing. You know what will be installed, where and why, before the first lift.
Floating pontoons, finger piers, access gangways, mooring blocks, chains and anchors. Installation on the surface and fixing underwater are done by the same team.
Inspection of moorings and anchoring, replacement of worn chains and fixings, repairs after a storm or a flood. A report after every visit.
Depth changes neither our team, nor our equipment, nor the way we prepare a job. It changes the gas we breathe and the emergency resources we bring.
Condition of the structure, measurements, photos and video. You receive a report your engineers can use, not an impression.
Underwater welding and cutting, concrete, sheet piles, piles, intake screens, pipelines, anchoring and corrosion protection.
Water intakes, pipelines and ballasting, pontoons and moorings, lifting and salvage of machinery or boats.
Screens, gates, intakes and stoplogs, down to sixty-nine metres.
A blocked intake cannot wait. We have done this work before: you can count on us.
Design, build and maintain, above the water and below the waterline.
Bridges, locks, quays, retaining walls and treatment plants: a condition, measurements, a report.
This is the T in TRSC, Team: collective expertise where everyone contributes to success. For each project we build the team from this panel, and when needed we call on the experts of the group's other companies.
Prepares the job and settles the plan, roles and equipment before arriving. Responsible for site safety.
Work together all year round. Some of them come from military diving, where nobody enters the water before the mission has been prepared.
Underwater welding and cutting on steel and concrete, to written and checked procedures.
Surveys, measurements and condition report your engineers can use.
Lifting, handling and navigation: the same team operates the equipment, with no second mobilisation to organise.
Chamber, gas and emergency response. The emergency plan for each site is agreed with the hyperbaric physician and the hospital that would take charge of the diver.
It goes off track because someone is being waited for, because the structure is only discovered once in the water, or because a part is missing. These are lost days, and they can be prevented.
| What costs days | What we do |
|---|---|
| The team meets for the first time on site | Our divers work together all year round. Nobody learns a colleague's way of working on your structure. |
| Preparation happens on site | Survey, work plan, equipment and roles are settled before arrival. We enter the water to work. |
| An equipment failure stops everything | The equipment comes from the group's fleet, maintained and replaced the same day in the event of a breakdown. |
| One incident and the job stops dead | Emergency response is organised before day one, with the physician and the hospital that would take charge of the diver. The chamber comes to the site when the dive requires it. |
Are the divers coming to my site your employees, and since when? Only an employment contract answers that.
Who is the hyperbaric physician for this job, which hospital would receive an injured diver, and has its chamber been notified? A name, a hospital and a date answer that.
On your last three comparable jobs, how many days were planned, and how many did it take? Dates answer that.
You don't have to watch a dive to know where your structure stands.
We come and see the structure. You receive a written work plan, a date and a price, not an estimate to be confirmed on site.
One update a day. Every dive is measured and recorded as it happens.
A report: the condition of the structure, what was done, what will need further work and when.
Wherever the structure is.
Today we work in Switzerland, Germany, Austria and France, on lakes, rivers, dams and harbours.
In France, you receive before day one the documents the law requires you to check: posting declaration, social security certificates and company certification. You have nothing to piece together.
Further afield on request: the team travels with its equipment.
Chamber, heavy equipment, procedures, insurance, qualified personnel: a large company carries them alone, an independent diving company rarely. TRSubC pools them. Network members keep their name, their clients and their region. They share our standards.
Recompression chamber and standby, boats, mobile base and hyperbaric equipment, rented to the network by TRSCharter.
Audits, certifications, insurance pool and group purchasing: compliance at a cost a single member could not bear.
Divers and technical staff provided by TRSCrew, to complete a team for the duration of a job.
A flyer, a brochure or a full file, depending on what the topic needs. Our documents are reserved for registered users: submit your request, we approve it and you access the ones relevant to you, in French, German or English depending on the editions available.
Certifications, licences, insurance, emergency plan principles, social security certificates.
