Oil and gas installations, offshore platforms and dredging vessels are in operation continuously. They operate in salt water, under chemical exposure and with temperature fluctuations that rapidly degrade steel. Corrosion is more than a cost factor. It is an operational risk. De Koninggroep provides surface preparation, coating, and preservation for steel structures in the oil and gas, offshore, dredging and industrial installation sectors. New-build projects, maintenance, and renovation. With an approach focused on predictable performance, long-term protection and minimal operational disruption.


In these sectors, downtime is costly. The outage of an installation or vessel has direct consequences for production, planning and safety.
Work is often carried out while operations continue. On platforms with limited access, on vessels with a short maintenance window between deployments, and in factories and terminals where multiple disciplines are working simultaneously. Room is limited. Time is in short supply. Safety requirements are strict.
Dredging and work vessels operate under exceptionally demanding conditions: constant exposure to salt water, heavy mechanical loads and near-continuous use. De Koninggroep carries out blasting and preservation work to protect these assets and ensure their service life.
We know the environment. On site and in controlled environments. Quality standards are the same everywhere, regardless of location or project size.
Early involvement means limited risk later. De Koninggroep's specialists are engaged in new construction, renovation, and maintenance work. We assess the condition of the structure, the load it is subjected to, and the desired service life. We align technical decisions and planning in advance to reduce execution risks and prevent unscheduled downtime.
Removing corrosion, existing coatings, and contaminants, and verifying cleanliness and surface profile.
Carried out in accordance with specifications and tailored to the operating conditions and environment.
Continuous monitoring and immediate correction where necessary.
All work is carefully recorded. Systems, measurement data and inspections remain fully traceable for asset management, classification and future maintenance and inspection activities.

In new-build projects, the basis for long-term protection is established. At this stage, the choice of system and application determines the maintenance intervals and operational service life of the installation or vessel.
During maintenance and refurbishment, we work within the constraints of ongoing operations. Dry dock periods and planned shutdowns are short. Every hour counts. We assess the current condition and determine where protection should be applied, repaired, or improved. Execution is phased and tightly scheduled, so that equipment is ready for use again as quickly as possible.



De Koninggroep works on installations and equipment in the oil and gas sector, offshore, dredging and heavy industry. Within projects where safety, availability and service life have a direct impact on operations and costs, including:
Conditions vary from project to project. The starting point is always the same: corrosion protection and wear control tailored to the actual operating conditions, using systems proven in practice. We use specialist coatings for chemical exposure, immersion, or extreme temperatures where they demonstrably enhance performance and service life. We apply innovations as soon as they have proven themselves in comparable conditions. You can find more about our applications on the Innovation & Technology page.

Clients in oil and gas, offshore and dredging choose De Koninggroep for projects where unplanned downtime has an immediate impact on operations. Delivery is always according to schedule, even within tight maintenance windows and operational environments where every day counts. Coating systems are tailored to actual operating conditions: chemical exposure, immersion and mechanical wear. On site, offshore and internationally, we deploy flexibly and coordinate closely with asset managers and other disciplines on site. After delivery, we remain available and accountable, even long after equipment is back in service.
