In-house Engineering
The North Sea can at times represent a very hostile environment for activities linked up to the oil industry. This creates numerous engineering challenges for all parties involved, including lift companies. SCHINDLER STAHL HEISER has in-house engineering expertise to cover most relevant technical specialities such as lift engineering, design and calculations, including frame statics. Sophisticated software enables the company to design and calculate not only the lift itself, but also the lift shaft. These shafts are often designed as separate units consisting of a steel or aluminium framework fixed to the structural steel construction on the platform or oilrig. The lift shafts are frequently located in hazardous explosion areas, thus specific customer requirements often include explosion protected equipment in addition to weatherproof covering, increasing the challenge to the design and engineering staff. The shafts are fabricated in modules and assembled together and fitted to existing structure either on the shipyard or building site, or transported directly offshore for final installation. Special focus needs to be put on materials technology and surface treatment. The company needs to use its expertise and long experience to be able to achieve a satisfactory operating life for each installation.

The SCHINDLER STAHL HEISER’s product line for the offshore market spans from new lift installations on new rigs or platforms, new lifts and lift shafts on existing oil installations or living quarters, through modernisations and refurbishment of old lift installations, to preventive or corrective maintenance and service.
