Specialists in tank cleaning

The KTV Group has 27 years of experience working with tank installations – offshore, on ships and rigs and at onshore facilities. Our customers have always considered us a reliable partner.  We carry out No Entry cleaning, recycling and waste treatment. We use tank profiling equipment, which is useful in determining correct methods and precise cost estimates before start-up.

Tank cleaning involves finding cleaning methods that limit environmental impact and making work safe for operators – at the lowest cost possible. Planning and time to prepare are a very important part of that process. Our BlueTag quality assurance system provides us with expertise and competence from around the world. It allows us to examine projects together to find the best solutions possible where environment, cost, safety and quality are concerned.

Our cleaning robots carry out No Entry cleaning, and we are the only maintenance partner on the market that can offer long-term maintenance agreements, in which we take charge of and document work involving tank inspection/cleaning and surface treatment. We can organize agreements that last up to 20 years.

Acoustic tank inspection system

The acoustic tank inspection system measures sludge volume and topology sediments at the bottom of crude oil storage tanks.

Manual methods to estimate sludge volumes utilize dipsticks or gauging rods to take measurements at only a few points in the tank. This results in inaccurate sludge volume measurements because real distribution is unknown. Our system solves this problem by taking precise readings for calculating sludge volume in the tank while it is in operation.

 

Safe, effective and cost-saving

Specially trained personnel and collaborative partners with approved tank installations/waste reception systems will facilitate safe and cost-effective work.
We cooperate with our customers to set specific times and locations for our work. We can do our work on ships and provide our services at the Hanøytangen quay in Askøy, Bergen (ISPS approved), or at quays where our collaborative partners are stationed.

We offer various types of agreements, such as single assignment, fixed term and fixed price – or assignments based on hourly rates.

Onshore and offshore

The KTV Group cleans tanks onshore and offshore. We are experts at finding solutions for common challenges where heights and cleaning methods are concerned. We clean diesel tanks, water tanks, ballast tanks, drill water, chain wells and product tanks – dry and wet. Among our many tank cleaning assignments, we can name classifications for Iceland Innovator, Deepsea Bergen, Transocean Artic, Songa Dee, Polar Pioneer, Deepsea Atlantic, Bideford Dolphin, Borgeland Dolphin, West Navigator, Transocean Searcher, Regalia, Transocean Leader and Safe Caledonia. Our Reference List is found here

We also have extensive experience cleaning thruster rooms/pump rooms, mud pump rooms, engine rooms, generator rooms and removing marine growth.

Tank installations/farms

cabot_tankbilde3-600x533

The KTV Group has years of experience cleaning land-based tank installation. In the past we were limited to cleaning tanks from 3 to 48 meters in diameter. Our personnel are also experienced in decantering (treating) waste and cleaning with No-Entry systems.

We have completed assignments for Shell, Esso, Statoil, Mongstad, Kollsnes and Sture.

 

Different types of tanks

KTV is able to clean gasoline and diesel tanks. We have extensive experience cleaning large-volume tanks for ships, offshore and onshore. We also treating tanks for so-called diesel bugs, and we carry out tank classification. Planning is an important factor in being able to work safely and effectively.

No Entry using robotics

 Robots can be controlled remotely without any humans entering a tank.

– Doing the job without scaffolding.
– The implementation process is reduced by 35%
– 15-20% less water savings
– NDT measurements can be done while washing.
– Can operate under water
– Can be operated via web/satellite
– Can provide up to 3000 bar pressure
– Can be equipped with a vacuum for collection and filtration

Our robots can perform tasks like cleaning structures without needing scaffolds or lifts. The robots are able to climb steel structures using magnets and run at high-pressure (up to 3000 bar). They can be used on vertical and horizontal surfaces. The robots are the result of many years of R&D and is especially suited for cleaning tanks, ships and rigs. The robots are also used to remove surface coatings.

The robots are remote-controlled so tanks are cleaned from the outside, so-called No Entry systems.

At land-based tank installations the robot is able to solve complicated cleaning tasks without scaffolds, reducing the need for personnel to enter such installations by approximately 65%. The robots are remote-controlled and is effective and fast. It can navigate on curves and works perfectly upside down. The robots can be programmed to run automatically for optimal efficiency, which reduces the overall process by approximately 35%. There are also environmental benefits. These devices reduce water use by approximately 15-20%.

The KTV Group is also working to improve the robots to operate under water using the same principles.

 

Hazardous waste

The KTV Group has the experience and technology needed to handle hazardous waste. We can ensure safe handling and quality assurance in terms of transporting, delivering and treating hazardous waste.

Our ISO 14001 certification is proof of our reliability in handling hazardous waste. We also use on-site recycling and process recirculation methods for large-volume tank cleaning projects.

Our QA system generates traceable documentation from beginning to end. Our customers can access the document archives from their own weblink/webpage.

The KTV Group has a fleet of ADR approved vehicles to transport and handle our customers’ waste in a logistical, safe and cost-effective manner.

 

Monitoring air quality using AQ MONITOR

AQ MONITOR provides 24-hour measurement and monitoring of air quality inside tanks and enclosed spaces. The customer can access these measurements/documentation in real time from their own webpage. The new regulations set by the Norwegian Labour Inspection Authority include even more stringent requirements that make the executing company or safety officer liable for non-compliance.

AQ MONITOR solves all these challenges. Personnel working in monitored environments can feel 100 % safe when this system is in use.

– Individualized monitors are unnecessary.
– The system also measures gases from solvents and flame cutters.
– Costs are reduced.
– Complete measurement data history is available for all hours and days.
– The sensors can be adapted to the customer’s needs.
– All measurements are available in real-time, online.
