Not known for their use in deeper waters, modular solutions are rarely considered in water depths over 60m. However, we used our flagship minimum facilities platform, Sea Swift, in a project off the coast of Malaysia in water depths of 65m. This uniquely-designed project was centred on a minimum facilities platform design.
This first-of-its-kind project didn’t come without challenges. Especially when the operator wanted to go from conceptual design to commissioning within 12 months, bypassing Front End-Engineering Design (FEED). But we also had to consider:
- a minimum fatigue life of 10 years
- installation via a jack-up
- the use of complex single, dual and triple splitter wellheads
We needed to install a minimum facilities platform to meet this challenge. So, how did we do it?
Knowing certain steps of the process were going to be bypassed ensuring optimal design was a crucial first step for this offshore platform project. In depths of 65m, and with topsides weighing over 400tonnes, developing a robust design mattered. To build a strong foundation, the conductor legs penetrated the mudline by a further 80m. The two subsea structures provided the required strength and stability needed to ensure the performance of the minimum facilities platform was maintained.
