How Euronav turned drag into data

ISO 19030 is ultimately all about the bottom line and that’s good news for tanker operators as recent Euronav experience shows*

When taking a look at the current tanker orderbook worldwide, two particular pieces of data stand out. First, almost 800 new vessels are shortly to be delivered. Second, approximately 100 of these will be ultra large crude carriers (ULCCs) or very large crude carriers (VLCCs). With these kinds of figures, it is clear there is some considerable extra capacity on the way. With such abundant supply of tonnage coming into the market, the global tanker shipping economy is under greater pressure than ever to be as efficient as possible.

A key measure of an operation’s overall efficiency is vessel performance. The two key components to appreciate when understanding vessel performance are power increase and speed loss. Having to yield to these components costs either time or fuel. In an industry where both these commodities are scarce, stakeholders from different corners of shipping are challenged to find appropriate solutions.

To aid in this process the International Organization for Standardization, in collaboration with industry experts such as Hempel, has developed a new standard: ISO 19030. This aims to enhance environmental performance and vessel efficiency, in addition to making the vessel negotiation and shipping process a more transparent practice. ISO 19030 defines the methods for determining changes in hull and propeller performance in addition to calculating a set of basic indicators to essentially provide an industry standard measure for propeller efficiency.

The relevance of ISO 19030 to operators is that it allows them to start analysing, with better accuracy and clarity, what needs to be rectified on any particular vessel in order to maximise efficiency and minimise fuel consumption. ISO 19030 is ultimately all about the bottom line: it gives shipowners the figures necessary to implement change initiatives if they need to. The standard further aids in facilitating better relationships between business owners and operators, allowing them to negotiate their business with greater transparency when engaging in conversations regarding such things as charter-party contracts, or anything that is related to speed and consumption.

The greater efficiency that ISO 19030 hopes to achieve supports Hempel’s goal to provide products that better suit customers’ needs. We understand that inefficiency can have a huge impact on a business and aim to innovate new technologies that add greater efficiency to our clients’ operations.

In the context of ISO 19030, one way we achieve this is through the right choice in coatings, in combination with our performance-monitoring service. Coatings help maintain a clean hull, so that vessels can maintain their required speed without consuming additional fuel. We are now able to determine accurate performance data and return on investment of a hull coating. What is more, by ascertaining exactly how fuel savings are being achieved, it is possible to make adjustments if performance drops.

Our fouling defence coating, Hempaguard X7, is testament to this. Hempaguard X7 delivers a significant 6% fuel-saving advantage over the entire docking interval compared with the next best-in-class antifouling solution, achieving outstanding resistance to fouling, even during idle periods of up to 120 days.

The secret to Hempaguard’s success is the technology driving it, our innovative Actiguard solution. It is the only hull coating to combine the low surface friction of silicone with efficient fouling-preventing biocides in a single coat. Unrivalled flexibility in fleet utilisation is also achieved, as Hempaguard retains its effectiveness when switching between slow and normal steaming.

Euronav, a global leader in the shipping of crude oil, has been using our silicone coatings to improve efficiency since 2007, and with good results. Keen to look deeper and have a complete insight into improving its long-term efficiency, Euronav decided to delve into the data following the excellent performance of Hempaguard X7 on its VLCC Famenne.

We began monitoring three of Euronav’s vessels in 2015, six months before they switched to Hempaguard X7. Months after application, the data clearly showed an increase in propulsion efficiency, of which a significant portion was directly attributable to Hempaguard.

Product-side solutions such as Hempaguard X7 have a clear role to play in fulfilling greater vessel efficiency, but this must be set alongside an industry move to better understand the importance of performance data. Taken together, these two tools can have a marked effect on vessel efficiency. In an over-tonnaged market, that is a significant advantage for any tanker owner.

Selektope antifouling technology adopted in new outfitting coating 

A new outfitting coating utilising the unique antifouling ingredient Selektope has been brought to market by Hempel. This latest coating product launch further confirms the industry’s acceptance of the technology whose powerful bio-repellent action prohibits barnacle fouling.

Selektope is included in Hempel’s GLOBIC 9500S product as part of a ‘smart biocide package’. The new antifouling was specifically formulated with Selektope to deliver boosted static performance against hard fouling for idle ships during the outfitting process at shipyards.

The accumulation of biofouling on the ship hull is becoming an increasingly dominant issue for shipyards, particularly those located in warmer waters. Newbuilds that lay idle in warming waters during the outfitting process can suffer the effects of intense fouling which can impact both the newly applied coating and the vessel’s performance after leaving the shipyard. This has resulted in growing demand for antifouling solutions that can ensure static performance during outfitting.

Selektope is an organic, non-metal compound that repels barnacle settlement on ships’ hulls by temporarily stimulating the barnacle larvae’s swimming behavior. It is characterised by high efficacy at extremely low concentrations, ultra-low leaching and flexibility to boost copper-based paint formulations or replace copper completely.

I-Tech AB, the company behind the bio-repellent antifouling, is urging end-users to check whether or not the organic substance is offered within all marine coatings portfolios.

The first publicly disclosed commercial application of Selektope was recorded on 1 November 2015 at Sembcorp in Singapore. Selektope was included in a new copper-free product from Chugoku Marine Paints (CMP), planned to perform as a five-year antifouling coating. The new CMP coating was applied to the side-walls of the vessel Calypso for Swedish operator Laurin Maritime. No special provisions were required beyond normal preparation work.
