Offshore Platform Decommissioning
In 2015 we set about designing a range of high pressure pumps, vacuum units, and air compressors for offshore platform decommissioning. Our existing range of equipment had been proven over two decades in offshore fabric maintenance work. It is highly regarded by the offshore service companies, many of whom are based in Aberdeen.
However, as many platforms undergoing decommissioning are subject to de-rated crane lift capacity and have little space for extra equipment on deck, we needed to create a range of lightweight, compact units which still give the same levels of performance and reliability as our existing range.
And so we introduced the OffshoreLITE range of high pressure pumps, vacuum units, and air compressors.
Offshore Platform Decommissioning Units – Main Features
We offer units with a maximum weight of 4,500kg in DNV-certified containers or crash frames, and modular units with individual module weights of 1,500kg. Our hot water jetting units weigh in at under 1,000kg.
We have considerable experience designing and building pump packages for platforms with restricted deck space and access. The knowledge we have built up over many projects, in particular chemical injection and CRI cuttings re-injection units, was utilized in our OffshoreLITE unit design.
With self-contained diesel powered units, and electric units designed to operate from a standard 63 amp 3-phase socket, these lightweight and compact jetting, vacuum, and compressor packages offer real versatility to the offshore decommissioning sector. See full details of our OffshoreLITE range.
