JOTUN PROTECTS ODFJELL SEMI-SUBMERSIBLE VESSEL

Monday, May 18, 2020 

Odfjell Drilling's 'Deepsea Stavanger', a dual derrick, dynamic positioned (DP), semi-submersible is set to work in demanding environmental conditions off the coast of South Africa for oil major Total, and will be protected with Jotun's anti-fouling SeaQuantum Ultra S and topcoat Hardtop One.

Odfjell Drilling faces a combination of high fouling intensity and strong ocean currents, which are likely to threaten the efficiency of operations. Heavy fouling on the rig hull will increase frictional drag and this, allied to the force of the currents against the rig walls, makes it harder to maintain the correct position. This creates a demand for greater thruster power. To ensure optimum operations and durability, both above and below the surface, Jotun is applying the premium anti-fouling SeaQuantum Ultra S and topcoat Hardtop One, a polixiloxane coating, at the Semco Maritime yard near Bergen, Norway.

“It became clear that Deepsea Stavanger required an anti-fouling tailored to deliver a clean hull, and optimal performance, in the most challenging environmental conditions,” said Lasse Isaksen, Global Concept Director - Offshore “Biofouling is as big an issue for the offshore industry, particularly with DP vessels, as it is for shipping, and with our established expertise in this niche we were perfectly positioned to find the right solution for this advanced asset. Our in-house anti-fouling team examined the individual vessel requirements, operational parameters, localised fouling intensity, and in-depth metocean data to determine the best coating. SeaQuantum Ultra S will deliver the results Odfjell Drilling and all its stakeholders demand, protecting the rig for long-term, durable operations, while its fast polishing silyl acrylate composition ensures a clean hull and optimal manoeuvrability and performance.”

The rig topside will be coated with Jotun’s Hardtop One, which offers gloss retention for protection in intense sunlight and UV exposure. As a single component product, the coating is said to be unique to the market, offering all the benefits of a two-component solution, but with increased simplicity, reduced waste and less environmental impact.

Håkon Hernes, Technical Superintendent, Odfjell Drilling, said: “We have a commitment to our customers to provide outstanding service and the highest quality, whatever the demands, and we look for the same standards in our suppliers and their products. The innovative combination of solutions from Jotun, providing first class protection and performance above and below the waves, shows they understand our needs and can help us tackle industry challenges. We’re delighted to have them onboard.”
