Nippon Paint Marine’s nano-based antifouling FASTAR I has been selected for a trio of box ships the Tsuneishi Group is building for China’s Jiangsu Ocean Shipping (JOSCO).

With an overall length of 146m and a 23.25m beam, each vessel in the series is based on Tsuneishi’s low-resistance hull form and includes an array of energy-saving technologies.

Lian Jian Guo, general manager, technical division, JOSCO, said: “We have very good experience with Nippon Paint Marine systems on our vessels, so were keen to add to the overall energy efficiency of these next generation vessels with the new FASTAR system. With the installation of advanced technologies designed to reduce energy consumption and emissions, these vessels will be the greenest in the JOSCO fleet.”

The advanced technologies to which Lian Jian Guo refers include Tsuneishi’s ‘TOP-GR’ and ‘MT-FAST’ systems, of which the former optimises the number, diameter, shape and geometric distribution of propeller blades to achieve greater propulsive efficiency. Further efficiency gains are achieved with MT-FAST’, which adds a wing-like device to the front of the propeller to alter water flows.

“The application of these two technologies combined with FASTAR is expected to contribute to significant fuel savings and help us meet environmental standards,” he said.

Gerald Mao, senior director, Nippon Paint Marine (Shanghai), noted: “JOSCO’s experience with our LF-Sea and A-LF-Sea antifouling systems has delivered fuel savings of up to 8 per cent, which can equate to a voyage free of fuel costs every twelfth trip or so. We anticipate FASTAR will deliver further cost savings and environmental efficiencies.”

Introduced to the market early last year, Nippon Paint Marine’s fourth generation antifouling uses completely new hydrophilic and hydrophobic nano-sized silyl acrylate components to more precisely control the release of biocides.

“It is by precisely controlling the release of biocides that we have been able to deliver a high-performing, low-polishing antifouling system that not only delivers unprecedented commercial benefits but also helps shipowners and operators meet emissions abatement and energy efficiency targets,” said Mao.

“Liner operators like JOSCO are facing increased congestion at port with at least 30-day waiting times so need a coating that delivers consistent 60-month performance unaffected by seawater temperature and vessel speed.

“FASTAR I has been designed to deliver optimum performance and save fuel after longer idling times, when conventional coatings experience increased biofouling,” he said.

Jun Ye, M & R sales director, Nippon Paint Marine (China), said: “For a containership with 80 per cent activity, operating at 18kts in seawater temperatures of 26 degree Celcius, a FASTAR scheme provides 60 months of service from a dry film thickness of 260 micrometre on the vertical sides and a 160 micrometre coat of on the flat bottom. A conventional antifouling covering the same 2000m2 area would require 1018 litres of paint versus 1330 litres.”
