Title: Arnbjorn Joensen: Innovator in Subsea Infrastructure

Introduction

Arnbjorn Joensen, a distinguished inventor based in Aberdeen, GB, has made significant contributions to the field of subsea infrastructure. With a portfolio of five patents, Joensen has demonstrated his expertise and innovative thinking in developing methods and apparatuses that enhance subsea operations.

Latest Patents

Among Joensen's latest patents is a groundbreaking method of decommissioning subsea infrastructure. This invention focuses on a method for dewatering a subsea pipeline bundle assembly before lifting it from the seabed. The method utilizes an elongate carrier pipe that features at least one internal fall sloping toward a drainage outlet and incorporates a venturi formation aligned with that outlet. By adding discrete buoyancy to the carrier pipe, Joensen's design elevates parts of the pipe, allowing water to drain efficiently down inclined falls toward the outlets. Additionally, injecting a dewatering fluid into the carrier pipe facilitates the expulsion of water, promoting rapid drainage through the outlets.

Another notable patent involves the method of installing a production buoy at a subsea anchoring location. Joensen outlines a process that includes floating the production buoy over the designated anchoring site and submerging it to connect tethers to the subsea anchoring location. The accompanying apparatus for this method supports efficient buoy deployment and secure anchoring.
