Design and Innovation

Design capability

GWF offers design services covering both general mechanical design and pressure vessel design to PD5500, BS EN13445 & ASME Standards. We utilise Solidworks 3D and Codex for Design/drafting and can also offer FEA when required.

Pressure Vessels come with full CE Certification to comply with the Pressure Equipment Directive (PED 97/23/EC). GWF generally employs the services of either Lloyds Register or British Engineering Services (Formerly Royal & Sun Alliance) to carry out the Notified Body role in pressure vessel design and manufacture but is happy to work with any Client preferences which have included Bureau Veritas, TUV and Parsons Brinckerhoffin in the past. We also manufacture Offshore Security Stores which come with full Det Norske Veritas (DNV) certification.

We are equally happy to work to client designs/drawings and do so on a regular basis with many OEMs, reverse engineering as and when required to produce obsolete parts for older plant and equipment.


GWF regularly offers expertise and experience to advise clients where we think we can add value to goods and reduce costs by utilising different manufacturing techniques and/or materials.We carry several graduate engineers and a metallurgist on our staff in addition to a wealth of practical experience gained over our 50 years in business. Whilst the company is predominantly workshop based, we regularly carry out site visits/surveys where we look to engineer out recurring problems by improving existing designs. GWF operates a continuous improvement policy.
