Co-operation to enhance performance monitoring
Chinese and Finnish companies extend their collaboration to include vessel performance monitoring
Shipbuilding Cooperation, and Finnish maritime software developer NAPA are extending their co-operation in a new project involving ship performance monitoring and applying optimised design techniques to real ships in service. The agreement was signed during the Marintec event in Shanghai in December.

The agreement extends an existing co-operation arrangement that includes the application of NAPA software to SDARI’s ship design processes and NAPA’s Loading Computer, which is said to enhance safe operation and maximise a vessel’s cargo capacity. The new agreement is in response
industry demands for improved vessel performance and the associated need for tools to provide real time performance monitoring to optimise operational efficiency during the lifecycle of vessels. NAPA president Juha Heikinheimo told
Marine Propulsion that the two companies have been co-operating since 2000, with the first joint project involving loading computers. The basis for the latest product is a 3D ship model. NAPA uses the design model created by SDARI to perform optimisation work and the in-service data can then be linked to the design to show how it was

actually performing, with analysis of specific parameters such as fuel economy. “The main driver is that ship operators want to reduce fuel consumption and maximise revenues by optimising routeing and operations with real time monitoring. There are currently thousands of ships trading without any proper monitoring of their performance,” Mr Heikinheimo said. He added that using this tool increases safety and can raise vessels’ secondhand values
and charter rates if the ship’s
performance and fuel consumption is known and independently verified. “Charterers might pay a premium to reflect the benefit of proven low fuel consumption.”

Mr Heikinheimo said: “Broadening the scope of our partnership enables us to serve the shipowners and operators even better by helping them to monitor and analyse actual ship performance. [They] have a significant savings potential of up to 30 per cent, which can be achieved with better designs and more efficient, well planned, monitored, analysed and optimised operations. NAPA solutions offer comprehensive tools for efficient operations and, in addition, a possibility to prove the superiority of the modern eco- designs and provide valuable feedback to the design process.” SDARI president Hu Jintao commented
to Marine Propulsion: “NAPA’s performance monitoring tool can assist at the design stage and it is also important to get feedback about how the ship is actually performing in different sea states. This will inform future designs.” It

Also at Marintec SDARI and DNV GL outlined their latest Green Dolphin 575 handymax bulk carrier design. This is a development of their previous Green Dolphin 38 version, incorporating greater fuel efficiency. The Green Dolphin 575 is designed to comply with expected future emission regulations,
featuring a number of
propulsion options. These include exhaust gas cleaning systems or dual- fuel operation with LNG. The core design

has an efficient Tier II long-stroke, low- speed main engine and a large-diameter slow-rotating propeller. As a result, main engine fuel consumption is about 22.8 t/ day with a 15 per cent sea margin. SDARI chairman Hu Jintao confirmed that the SDARI Green Dolphin 38 bulker design has achieved 44 firm orders plus 36 options spread among 10 shipyards. “I expect most options to be exercised as ship prices are now rising and I expect total orders to reach 100 ships.”

feedback from actual ships in operation and particularly in a loaded condition, he added. "Sea trials are done in ballast conditions and relatively calm sea states.”
He said that results from the system could result in recommendations for retrofitting. “Currently we get data feedback from only a very small proportion of ships built to our designs. The tool can be used to verify claims by other suppliers, such as coatings and other equipment for fuel savings and efficiency improvements on an objective basis and this will also help suppliers to verify their claims. It is also useful for educating crews in efficient operations.” He spoke of the two companies’ longstanding co-operation, which means “we can offer speedy delivery to clients for new projects. We have been using NAPA tools for many years, which improve calculation efficiency for different ship types and in daily work. From 2001 we decided we would do that for loading computers which saves time in getting data validated. The NAPA loading computer is similar and can transfer data with output no different.” He has a high regard for SDARI’s vessels. “[They] are already designed to industry- leading standards, but in order to increase competitiveness in an industry increasingly focused on cutting operating costs, we hope to introduce NAPA’s performance monitoring solutions to demonstrate the superior operating efficiency of our designs,” he said.
