4Subsea Speaks at OMAE 2022

Asker, June 7th 2022 – 4Subsea will speak at the OMAE conference held at the Congress Center Hamburg, Germany on the 7th and 8th of June.

The 41st international conference on Ocean, Offshore and Arctic Engineering (OMAE 2022) will take place from June 5th-10th 2022, with the 4Subsea team in attendance presenting three papers during the five-day event.


Ocean Engineering session (Marine Hydrodynamics I) – Tuesday 7th June

4Subsea’s Ali Catin and Vegard R. Solum will be presenting ‘Machine Learning Based Prediction of Wave‑induced Vessel Response’.

When and where: Tuesday 7th June 2022, 10:30-12:00 – Room Y3

The team will share their thoughts on why current methods of predicting vessel response could be bolstered by machine learning. By using sea state forecasts to predict vessel response spectra combined with the data captured through the existing calculations of response amplitude operators (RAOs), the two-point approach can improve wave-vessel response predictions.

Pipeline, Risers, and Subsea Systems session (Rigid Risers II) – Wednesday 8th June

4Subsea’s Håkon Molven will be presenting  ‘Conductor Instability – Experience from 10 Years of Monitoring Drilling Operations on Subsea Wells in Harsh Environments’.

When and where: Wednesday 8th June 2022, 11:00-12:30 – Room Y2

The presentation elaborates on the developments of 4Subsea’s Subsea Wellhead Integrity Monitoring (SWIM™) technology over a decade, used across more than 300 drilling campaigns. The presentation will summarise the observations of conductor instability while providing examples of monitoring results, showing instability issues, and actions taken to react to this issue. Statistics on some core metadata such as water depth, region, and well type will also be discussed and summarised.

4Subsea’s lead engineer, Harald Holden will be presenting on “Rationale for Norsok U‑001 5th Edition Revision of Static and Cyclic Subsea Wellhead Loads”.

When and where: Wednesday 8th June 2022, 11:00-12:30 – Room Y2

The presentation will look at Norsok U‑001, the Norwegian national standard with requirements and recommendations that are supplementary to the ISO 13628 series of standards. Harald will present the analysis methodology employed, explain how design loads have been extracted from these results for the upcoming 5th edition and outline quantifiable advice on maximum and cyclic load reduction potential than can be extracted from underlying studies.
