More proactive technology needed to combat biofouling

The rapid pace of technological innovation has had a growing impact on the shipping industry.  But as owners and fleet managers face increasing pressure to improve environmental performance, new technologies will be necessary to ensure a profitable and sustainable future.  The impact of biofouling on ship fuel use and emissions has generated increasing attention. According...

Digital data for dry-docking maintenance

An effective vessel maintenance strategy involves accurate and reliable data and an understanding of the individual ship, but it also involves combining the right human competencies with knowledge obtained from data to succeed in this space. This is the opinion of Steen Lykke Pedersen, head of dry dockings and maintenance strategies at Maersk Supply Service....

Shipping’s clean up ACT – a proactive approach to realising the potential of clean hulls

Dr. Mario Tamburri, director of ACT/MERC, argued that a huge win-win for both commercial shipping and the environment can be achieved with a holistic approach to biofouling and better in water cleaning of vessels. That includes ‘getting proactive’ on one of our industry’s most pressing challenges. Ask Professor Mario Tamburri a single question about vessel...

Biofouling demands urgent and proactive approach, stresses Bellona

The risks posed to both the environment and the sustainability of commercial shipping by biofouling should not be underestimated, according to Norwegian environmental pressure group Bellona. The issue, which has yet to be tackled by any meaningful international legislation, apparently poses a serious threat ‘triumvirate’. However, as Bellona points out, by tackling it head on,...

Proactive measures needed to improve hull performance, says Jotun Marine manager

Hull and propeller performance have a much larger impact on vessel efficiency than previously thought, says Jotun Marine analyst manager Manolis Levantis. According to Mr Levantis, “We estimate that the average yearly speed loss for all vessel types and trades, regardless of what anti-fouling is used, is about six percent. For a typical bulk carrier,...

DNV GL approves Wärtsilä SceneScan DP system

Wärtsilä has received type approval for its SceneScan position reference system by DNV GL. As the world’s first laser-based targetless relative dynamic positioning (DP) reference system, SceneScan represents a paradigm shift from conventional DP reference systems. It can work without the need for pre-placed positioning targets, thus providing significantly greater operational flexibility than with conventional...

Optimising ship inspections with autonomous drones

Regular inspection and maintenance of ships’ tanks to detect corrosion, cracks and other issues is essential to minimise permanent damage and avoid hefty costs. Human inspectors have traditionally entered tanks and examined them visually, but this can be dangerous and expensive. New research indicates that autonomous drone-based surveys could offer a safer and more efficient...
