What we do
20th August 2019
TSG Marine were approached by a client to assist with the replacement of two damaged turbine exhausts on-board an offshore platform in the North Sea. We provided the integrated analysis, design, technical support and project management services required to deliver and install two bespoke replacement exhausts, on time and under budget.
We work closely with out clients at the outset of a project to ensure we understand any specific criteria that need to be taken into consideration during the design phase. In this project, there were no hot works permitted at the work site and there was no crane access due to the location of the turbine exhaust.
We focus on creating value for our clients; providing pragmatic, innovative and cost effective solutions. For this project, like for like replacement was an expensive option.
We designed and fabricated replacement exhausts in manageable sections promoting ease of fabrication, transportation and installation.
Our Engineering Team carried out a full review of the original drawings provided by the platform operator before commencing the design. Structural calculations had to be carried out to ensure the functionality and safety of the systems that were involved in the replacement.
An investigation into the actual failure mode revealed that one issue related to jamming of the sliding feet installed to allow expansion. A revised arrangement was designed to eliminate this risk.
TSG Marine managed all aspects of the installation and our dedicated team worked effectively and efficiently to complete the work within the required timeframe.
The installation environment had limited space and therefore we designed an installation methodology to take account of this. Site modifications were made to create a suitable and safe working environment for our installation team.
The new exhausted were fabricated in one and two meter sections to ensure safe lifting operations could take place without the need for a platform crane. The installation took place while the platform was in operation and our team worked with precision and accuracy in a challenging environment to ensure maximum uptime.
The project was regarded as a huge success; with the work scope completed ahead of schedule and to a high standard.
