A rubber expansion joint, years overdue for replacement, triggered a complete blackout on the Interislander ro-pax ferry Kaitaki off Wellington Harbour in January 2023. Iain MacIntyre reports on the investigation, the prosecution and the questions that remain.

Fully electric, eCSOV’s are being designed in Spain for Bibby Marine. Battery power, with enough energy to power a CSOV for 24hours, will increase efficiency and cut costs according to the company. New and more thermally stable batteries will aid the transition.

Power generation and offshore support vessels are both in the frame to benefit from fourth-generation small modular nuclear reactors. Ulsteinvik and Island Offshore explore the possibilities.

Deeper, more exposed and less accessible fossil fuel reserves require more sophisticated offshore support vessel designs. With floating LNG increasingly in demand to help access and process fuels.

Vessel owners of 10-year-old ships are going through a mid-life crisis. To retrofit or not to retrofit, that is the question? Can investments in energy savings be recovered in these not old, but not new ships.

The digital age is transforming the ship repair industry as online monitoring and digital twins linked to a burgeoning predictive maintenance regime takes hold.

Visibility is becoming increasingly critical as charterers must now calculate Scope 3 emissions from their supply chains. Speed optimisation is helping to reduce the total.

Australia’s first 100% electrically driven passenger ferry, a collaboration between Aus Ships and Volvo Penta, aims to validate scalable electric marine propulsion with the overall aim of decarbonising the country’s waterways.

Can diagonal deflector strakes solve the classic deep-vee compromise? Petestep’s hull technology is promising faster planing, lower slamming loads and efficiency gains across the fast craft market.

Battery specialist Corvus Energy discusses how it is working on large-scale battery integration projects that reshape weight distribution and stability design in high capacity ferries and fast craft.

A new era in offshore power has seen the development of the first Energy Islands off European coasts. The first will be the six-hectare Princess Elisabeth Island, which is under construction 45km off the coast of Belgium and is due to be completed in 2028.

The first wind turbines to be deployed are reaching the end of their operational life. The question is, should the sites be re-used or retired?
