Project

Supported by DHRTC-DTU via Smart Water Flooding Flagship Programme. Two PhD positions. The objective of the SWTS is to develop a smart water management system that addresses both optimal operational performance and process development/design, by employing the advanced control and big data analytics technologies. This work will focus on innovative analysis, design and development of both Produced Water Treatment (PWT) and Injection Water Treatment (IWT) for offshore enhanced oil recovery using advanced water-flooding technology.

Mussels and other marine fouling settle on the part of offshore wind turbines and production platforms that is underwater.
The fouling worsens the load from the waves and reduces the load-bearing capacity of the structure by 25-65 percent. Today, the fouling is removed manually – typically using manually controlled underwater robots – which is a time-consuming and financially burdensome process.

The idea for the solution consists of three elements. 1. cleaning rings around the supporting structures that remove fouling when the water moves. 2. a robot that can move on the supporting structures and send a message about the size of the fouling. 3. A robot that can remove fouling by high-pressure washing underwater. The effect of the solution will be an extension of the service life of the structure, and an expected reduction in costs by 30-40 percent. In the North Sea alone, the industry currently spends a three-digit million amount annually on removing marine fouling.

Vessel propellers have reduced power efficiency with increased growth of barnacles and fouling, leading to an

increase in fuel consumption as high as 5%. SubBlue Robotics has developed an underwater propeller po-
lishing robot that allows for propeller polishing without the use of divers, and is capable of careful, precisepolishing of curved surfaces. As no divers are in the water, it can polish when the ship is loading and unloading

cargo, thus saving the shipowner valuable idling. Idling is the reason why the propeller polishing is often skip-
ped. The project will give technical robustness to the existing prototype, develop commercial grade components, and test the robot on commercial vessels. Leading partner is SubBlue Robotics, who has worked on

the designs and prototypes since 2016, the MMMI now IME institute at SDU provides knowledge on robots in harsh

enviroments, while shipowners DFDS and Maersk and diving company Odin Diving represent the market de-
mands the robot must meet. Three senior executives from CoGrow have invested in SubBlue Robotics, who

has just secured yet more capital and competences from two more investors.
