A.Hak Industrial Services approved by Saudi Aramco

April 14th 2015

A.Hak Industrial Services is very proud that Saudi Aramco has officially approved our Online Tank Inspection services. The service is now officially registered in the Saudi Aramco system and is available for all Aramco plants.

In 2014, the Tank Division of A.Hak Industrial Services Middle East LLC conducted a trial at one of the sites of Aramco in the Kingdom of Saudi Arabia for the online inspection of fire water tanks. These tanks cannot be taken offline for inspection and that is why they asked A.Hak to use their proprietary tank inspection robots to perform this inspection while the tank is in operation. After the inspection Saudi Aramco performed an evaluation of this project, which led to the official approval of our services.

A.Hak Industrial Services will shortly start trials to get approval from Saudi Aramco for its proprietary inspection technologies. Not only for fire water tanks but also for tanks with hydrocarbons (white products) and crude tanks.

New 3” ultrasound Piglet® available

April 19th 2016

A.Hak Industrial Services has recently launched its new 3” pipeline and furnace inspection systems, available for projects worldwide. This most recent development is part of a new range of faster tools with XYZ mapping possibilities.

The first pilot projects are already executed successfully. ‘Which was fully as expected since our flexible design of our tools guarantees a smooth bi-directional inspection in every pipeline configuration’, states Mr. Edwin Rosier, Sales Manager Inspection Services.

The new range of fast Ultrasound Inspection tools is an addition to the well proven High Resolution Piglet® tools which have already been renown for years now and are available for diameter ranges between 4” and 46”.

All A.Hak Industrial Services’ tools are free swimming inspection pigs which can be used for all kinds of piggable and ‘non-piggable’ pipelines such as lines with mitered or back-to-back bends with radii (less than) 1.5D. Edwin Rosier adds: ‘Even unbarred tees are not a problem for our intelligent tools’.

Due to the real time monitoring of the inspection data and the possibility of A.Hak Industrial Services executing its own cleaning works, a successful data collection is mostly guaranteed. ‘On request we can report pipeline inspections with ultra high resolution and even report within 24 hours for furnace applications’.

For further information please contact our head office in The Netherlands:

March 13th 2017

At the StocExpo Rotterdam from 28 – 30th March A.Hak Industrial Services B.V. will be introducing his new Online Tank Inspection Systems (OTIS) for Petro chemical plants, airports, water and nuclear industries.

Due to local regulation issues, tanks usually need to be taken out of service for a fixed time period for inspection, without knowing in advance if this is actually necessary. The new Online Tank Inspection Systems can provide inspections according to API-653 standards, which allows you to avoid having to take the tank off-line. Together with an ATEX-153 ‘safe-working’ declaration by DEKRA and an exclusive developed safety system the robots are one of the most advanced and safe on-line inspection systems on the market.

Great accuracy
A.Hak Industrial Services’ patented acoustic navigation system – equipped with navigation pingers in combination with other supplementary systems on the robot and navigation transducers on the tank shell – is used to pinpoint the robot’s location. Using onboard UT transducers, developed with years of knowledge and expertise from our pipeline inspection services, the robot follows a predetermined digital inspection grid and can collect millions ultrasonic scans of the tank bottom in order to perform computerized data analysis. The robot is equipped with an onboard sonar system to detect objects in the tanks. When operating in clear fluids, we can equip the robot with HD cameras for visual inspection and navigation. The navigation allows us to reproduce our inspection grid in the future to determine corrosion rates with great accuracy. Our robots can maneuver in tanks containing sludge of up to 30 centimeters (12 inches) in depth.

Safe and cost-effective
Inspections involving a human presence increase safety and environmental risks, and traditional tank bottom inspection technologies require tanks to be offline during inspection. They must be drained, cleaned, degassed and ventilated – all of which incur significant costs for tank owners. By using our robots, the tank bottom inspection takes significantly less time, plus it is safer and more cost-effective. A.Hak Industrial Services’ storage tank inspections will ensure the safety, reliability and integrity of your storage tank, while providing more efficient operations.

In Tarragona a team from A.Hak Pipeline Services is working hard to clean 2 benzene tanks at the Repsol plant using the ARCC system. Our goal is to clean the tanks and lower the LEL level by using our Non-men Entry tank cleaning system in combination with A.Hak SafeGuard. Due to the ARCC system we as A.Hak are capable to clean without entering the tank. When the service is completed successfully the tanks will be ready to entered for maintenance and inspection. ARCC (short for ATEX Remote Controlled Cleaning) is a self-contained system in which the pump, generator and an operating and control room are all fitted into a single container. A.Hak Safeguard is added in 2 batches, with use of a vacuum truck the sludge will be removed from the buffer tank. Finally a water wash will be applied, the gas phase of the tank will be ventilated (degassing) and the manual final cleaning can commence. At this moment the first tank has been cleaned successfully and the team is currently busy rigging up the equipment to start on the second tank. Read More.

New governance structure, new CEO

June 20th 2017

On June 20, 2017 A.Hak has introduced a two-tier governance model, consisting of an Executive Board and a Supervisory Board. Iain Light has been appointed CEO of the company. Marco and Mariska van Geenhuizen, members of the current management, will take a seat in the Supervisory Board, together with Régis Rivière. A.Hak remains a family-owned company with the Van Geenhuizen family as its shareholders. In recent years, A.Hak has faced challenging market conditions, especially in the oil and gas industry, along with many other companies in our industry. This led to a negative result in 2015. In 2016 A.Hak initiated a process of organizational development. In 2016 and 2017, the company has been able to produce improving results, partly because of these efforts. "With the change in governance structure we feel we can accelerate this improvement", say Marco and Mariska van Geenhuizen. "Since the beginning of 2017, we have been working with Iain Light on a long term strategy for A.Hak. We are fully confident that he will take the next step in the professional development of the organization, together with his Executive Board, our staff and the management of the A.Hak business units.”

New Executive Board
Iain Light has worked in the testing, inspection, and certification business for all his professional life. Drawing from this experience, he is very well introduced in A.Hak’s main markets. Until the end of 2015, Light worked in the Netherlands as CEO of Applus RTD, a service provider in the field of non-destructive testing, inspection and certification, serving mainly the pipeline industry. Light comes from the UK.CFO Remco Smit and CHRO Rob Bombeeck will be the other members of A.Hak’s Executive Board.
