Quality Assurance

Quality is the core aspect of safety and of reliability.

The company is a voluntary member of the“Güteschutzgemeinschaft KampfmittelräumungDeutschland e. V. GKD.” [a body monitoring thequality of work], and is committed to maintainthe quality standards for the disposal of explosiveordnance and at the same time it is subjected topermanent monitoring and stringent qualitycontrols. This is in addition to the regulationsand checks conducted by the“Berufsgenossenschaft Chemie und der Ämterfür Arbeitsschutz” [a body monitoring safety].

Quality management puts the expertise of acompany to the test. Therefore the company hasdecided to initiate the dynamic process ofcertification according to DIN EN ISO-9001:2008.This adds further impetus to the improvementof the efficiency of the safety concept for everyclient and the staff teams involved.

P-H-Röhll NRW GmbH

P-H-Röhll today deploys detection systemsfrom Vallon (Eningen) and the most modern“Vallon EVA2000” software with graphic realtime representation. Thus, the most stringentdemands for the highest degree of safety interrain examination and for the disposal ofexplosive ordnance are fulfilled.

Reliability

P-H-Röhll NRW GmbH is a service-oriented partnerfor all questions relating to the disposal ofexplosive ordnance. From the detection right tothe disposal of soils contaminated with theinherited burdens from hostile activities andactions by the military, our experts are activenation-wide to ensure the risk-free post-miningland use and to allow the productive use ofcleared sites.

The continuous framework agreements inNorth-Rhine Westphalia with the Dusseldorf(Cologne) and Arnsberg district administrationsform the basis and are a proof for a reliable andsuccessful cooperation in the region.

Staff & Quality

Cooperation is a core value in our enterprisewhich today comprises a workforce of 76.They are experts in their field and all, withoutexception, have long-standing experiencein the disposal of explosive ordnance. Theyreceived their training mainly with the GermanArmed Forces and possess expert knowledge oncurrent-type NATO ammunition. With an averageof 15 years of practical experience per memberand with constant on-the-job training this formsa pool of expertise that provides a lasting supportfor the company.

Active team spirit is promoted and it is aconstructive element of the Röhll training concept.This is a sensitive process asking for active sharingof personal experience and formal knowledgewith all team members. The extensive take-overfrom the historic Röhll company supports thisgrowing pool of knowledge within the enterprise.

Core activities

P-H-Röhll NRW GmbH has established itself in explosive ordnancedisposal with the following activities:

a. Surface detection on land and on water (site clearing).b. Depth range detection / bore hole detectionc. Bomb disposald. Salvaginge. Detonating of ammunition foundf. Computer-aided recording of probe readingsg. D-GPS & optical surveyingh. Company based electronic service / stationary and mobile workshop

a.) Surveys of sites surfaces are documented as part of the projectplanning stage on the basis of precise cartography and followingtested measuring routines. Using various special probes of well-knownGerman special manufacturers (Vallon / Foerster / Ebinger) we areprepared for any type of situation we are confronted with in theterrain and soils. All phases, from the detection to the excavationand up to the recovery, are executed and documented in detail inaccordance with the specifications of the KBD.

With large-scale detection campaigns in the Huertgenwald [historiccombat zone] (former district of Aix-la-Chapelle) P-H-Röhll NRWhas gained extensive practical experience. A great part of the staffhas more than 30 years of active experience in terrain securing.

b.) A number of drill gangs, equipped with drill gear for depth-rangedetection is available. Experienced groups and staff from Europe’soldest privately-owned company for the disposal of explosive ordnance– the reliable “Röhll bomb clearing gang”. Famous for their practicalexperience and their sensitivity in drill-hole detection, they deploya variety of systems and special drilling equipment owned by thecompany. A range of mobile systems allows the fast deployment onsite with high drilling rates.

The aim of this process – from the measurements taken of the drillhole to the evaluation of the computer generated diagrams to thedetection and exposure of the bomb – is the professional recoveryof the bomb. All this is carried out and controlled by experiencedgroup leaders.

c.) The company’s scope of services includes the project-relateddisposal of bombs and mines. For the recovery of explosive ordnancein any variety of soils the company deploys aluminum-framed tunnelingframes allowing safe digging operations up to the site of discovery.Company salvage groups then identify the type of bomb and makepreparations for the defusing and the salvaging.




d.) Salvaging from the water is gaining ever more importance for thesalvaging side of the company. The peculiar conditions there requirecreativity for the use of gradiometric processes and promote the in-house development and the use of specialized detection automatssuch as the ones used on the Rhine, for example (Andernach clearingsite), where they are used for underwater detection. A self-designeddug-out separator was used on the Datteln-Hamm-Canal (Luenensite) which made it possible to detect 400 square meters/day of canalsoil and clear it from foreign bodies and metal and war ammunition.A cooperative partnership exists with the Huelskens HydraulicEngineering company of Wesel (Germany) allowing the deploymentof heavy equipment and cranes for the salvaging of heavy metalobjects and other obstacles posing a danger to navigation.

e.) The identification of thetype of a bomb and theassessment as to thetransportability are part of thepreparations for a project.The particular experience ofthe gang’s foreman decideson what is he safest practicalsolution. Services include thedetonation of ammunitionfound and the properintermediate storage andsecuring of the hazardousobject.

f.) P-H-Röhll NRW supportsinnovative solutions for theeffective disposal of explosiveordnance. The computer-aidedrecording of probe readings is

one of many factors that provide optimum on-site support for thequalified work-gangs and to provide efficient solutions for the client.Using the most modern equipment and the “EVA2000” software byVallon (Eningen) the interplay between experience and technologyreaches new dimensions.

g.) The experience of the measuring staff and the correct handlingof the D-GPS measurements make the search easier and more accuratearound the suspected site-points.

This satellite-based system compares the terrain’s coordinates withan accuracy of a few decimetres [1 decimeter is approx. 4 Inches]with aerial photographs on hand and this leads to a faster andsuccessful detection. Apart from improved search results the systemalso improves the efficiency for large area detection.

h.) The in-house electronic service and thecompany’s mobile workshop make P-H-Röhll NRWa reliable partner for complex project work.Permanent controls, maintenance and calibrationof our measuring instruments by our physicistThomas Heinrich secures the highly sensitivemetrology in the workshop area and on thecompany-owned trial field.

Training program

Internal training is conducted in our own seminarfacilities. Specialized knowledge regarding thetopics of detection, calibration and salvaging is

passed on to all staffmembers in permanentbasic and further trainingcourses. The chief trainingcoach and the physicistThomas Ebbinghaus are theguarantors for thoroughexpert knowledge.

The main aims are thedevelopment of complexproject processes and theadaption of the detectorsand the working tools to

the state-of-the-art level. By passing on expertknowledge and the exchange of experiencegained the already high standards of qualityachieved by P-H-Röhll NRW GmbH are furtherimproved and the effectiveness of the disposalsand the on-site safetyare further enhanced.

Safety comes first

The disposal ofexplosive ordnance iscarried out in areassuch as bomb-throwing theaters,combat zones,detonation sites,military traininggrounds, wherepublic building activities are being planned orwhere public use of certain sections as recreationarea is anticipated. These measures lay the

foundation stone for a reliable increase in valueof these areas, which have been cleared and canbe safely handed over for example after theremoval of inherited burdens and freedom fromhazardous substances.

The user will be provided with the highest degreeof safety – with work the success of which canonly be assessed by the quality of the entire project.This is why P-H-Röhll NRW GmbH is relying onthe interplay between experienceand constant training on a levelthat conforms to the lateststandards, in order to protect allparticipants of a project.An assessment of the disposalof explosive ordnance on eco-nomic criteria alone is onlyconditionally possible, anassessment on the basis ofpiecework is impossible byits very nature and even life-threatening in the last resort.

Safety, defined as a qualitycriterion is he recipe for successof the Duren-based P-H-RöhllNRW company. With a cleardocumentation and a monthlyassessment the client attains acalculable service combined witha minimal risk for the reliabledisposal of explosive ordnance.

We hope to have given you a comprehensiverepresentation of our company and are lookingforward to cooperating with you in future. In caseof receiving an order we would like to assure youthat you will receive our continuous and committedprofessionally executed services.

With kind regards

P-H-Röhll NRW GmbH… the explosive ordnance remover
