September 2018 Project and Technology Update

Thanks to an increased focus on efficiency and a continued commitment to reliability and meaningful data, Welaptega has ridden the wave of change brought on by the recent industry downturn and further solidified its position as the industry leader in in-situ mooring inspections. After a busy Summer 2018 that saw us inspect more than ten mooring systems of permanently-moored floating assets, we wanted to take a moment to let you know what we’ve been up to.

Summer 2018 saw Welaptega perform two multi-asset mooring inspection campaigns in the North Sea – one for a major operator in the UK and the other a major operator in Norway. These jobs were rounded out by single asset inspection campaigns where we were called on to meet the increasingly robust class guidelines for mooring inspections. You can read the latest guidelines here: DNV-GL 2018, LR 2018, BV 2015, ABS 2018.

Looking ahead to later this month, Welaptega is off to the Australian Northwest Shelf to inspect some of the largest mooring systems in the world. The 21- and 28-line systems are designed to withstand the intense, cyclone heavy, weather patterns of the Timor Sea. The multi-asset campaign will use the latest generation of Welaptega’s industry-leading chain inspection technology, the CMS (a patented chain measurement system).

Our optical Chain Measurement System (CMS), the latest generation of which was released in 2017, offers numerous benefits over alternative chain inspection technologies. Namely:

  • Accuracy: CMS is accurate to less than +/- 0.5mm
  • Deployment Time: The CMS tool has no moving parts and simply sits flush against the chain to collect data. This means there is no time wasted trying to “fit” the tool onto the link. Also, moving from one measurement site to the next only requires the ROV to slide the tool down or up the chain.
  • Specifically designed to be capable of being deployed in high-heave environments. Most recent 2018 high-heave chain measurement campaigns: Voyageur Spirit (North Sea), Erha (West Africa), Alvheim (North Sea)
  • 3 Measurements at Once: The CMS collects two inter-grip measurements and one link length measurement from a single placement of the tool
  • Close Visual Record: CMS uses an optical system to collect measurement data, so CMS will collect high quality images and video of the measurement locations in addition to the actual dimensions.
