Electrical Drawing Bureau — Netherlands & Benelux

Your Specialist Electrical Drawing Partner in the Netherlands

Technisch Tekenbureau Verbogt (TTV) is an independent specialist electrical drawing bureau based in Bergen op Zoom, the Netherlands — strategically located between the Rotterdam port area, one of the world's largest petrochemical clusters, and the port of Antwerp, Europe's largest petrochemical complex. Founded by Christian Verbogt, TTV brings over 20 years of senior AutoCAD expertise in electrical engineering, instrumentation and control to every project.

TTV delivers a comprehensive range of electrical drawing services for the heavy industry, petrochemical sector and offshore industry: from P&ID diagrams, single-line drawings and circuit diagrams to cable schedules, cable calculations, instrumentation and control (I&C) drawings, loop diagrams and complete as-built documentation sets. All deliverables are provided in AutoCAD DWG/DXF and PDF format, fully compliant with NEN 1010, NEN 3140 and NEN 5152.

TTV has delivered electrical drawings and engineering support for leading international companies including Shell, Fluor Corporation, SPIE, ExxonMobil, Evos, Allnex and AEVO. Our documentation standards and drawing conventions align seamlessly with the project systems and quality requirements of major international engineering bureaus — with no learning curve and no compromise on quality.

Whether you need a one-off drawing package for a greenfield project, flexible CAD drafting capacity to meet a deadline, or a long-term outsourcing partner for your engineering department's electrical drawing work — TTV delivers with the speed, precision and NEN compliance that industrial and petrochemical projects demand.

Our Services

What TTV Verbogt Delivers for Your Project

From a single P&ID revision to a complete electrical documentation set for a greenfield petrochemical plant — these are the three core service areas where TTV Verbogt adds value for international engineering clients.

01. Electrical Design & Engineering — Industry and Petrochemicals

TTV Verbogt provides full electrical engineering documentation for complex projects in the heavy industry and petrochemical sector. We deliver complete drawing packages including P&ID diagrams, single-line drawings, circuit diagrams, cable schedules and cable calculations — all fully compliant with NEN 1010 and NEN 5152, and structured to meet the documentation requirements of major international engineering bureaus such as Fluor Corporation and SPIE.

For installations in hazardous areas, we work in accordance with the ATEX Directive (2014/34/EU) and the applicable NEN-EN IEC standards. TTV has extensive experience with the specific documentation requirements for ATEX zones in petrochemical and industrial environments.

02. Instrumentation & Control (I&C) Drawings and CAD Support

TTV Verbogt specialises in the preparation of complex instrumentation and control (I&C) drawings for industrial and petrochemical process installations. This includes loop diagrams, instrument schedules, I/O lists and control system diagrams — all produced in accordance with ISA standards and the internal standards of your organisation.

We also offer flexible electrical CAD drafting capacity for engineering departments and drawing offices — ideal for deadline support, capacity peaks or the structural outsourcing of your electrical drawing work. TTV works within your existing drawing standards, naming conventions and templates, with no learning curve and no loss of quality. We have direct experience with the project systems and documentation standards of Fluor Corporation, SPIE and Shell.

03. As-Built Documentation and Technical Archive Management

Field conditions rarely match the original design exactly. TTV Verbogt processes your red-line mark-ups and field changes into accurate, structured as-built AutoCAD files — the definitive record of your installation as it was actually built. All as-built documentation is produced in compliance with NEN 3140 and is ready for statutory inspection, insurance assessment and future maintenance or expansion.

We also provide complete technical archive management services — digitising and restructuring legacy paper archives and disorganised digital files into a clean, searchable and future-proof AutoCAD archive. TTV has managed as-built documentation for installations ranging from single-floor commercial buildings to large-scale petrochemical complexes.
