Operators adopting CBM strategies can improve vessel uptime, reduce unplanned repairs, manage drydockings more effectively and reduce maintenance costs, said the ESRG report authors. For example, container ship operators could improve their equipment and scheduling reliability, and reduce fuel costs. They could use the onboard data to operate ships more efficiently, such as optimising the configuration of generators or engines. They could optimise the vessel’s power systems based on the actual electrical load and the performance of specific systems on the ships.
This is particularly relevant if ships are carrying large numbers of reefer containers that have high power requirements for refrigerating cargoes. Operators could also use the data to reduce vessel speed

It is relatively easy to install industrial internet technology on a fleet of newbuildings, but far more difficult on older vessels. Owners would need to do a major retrofit of these vessels with sensors and integrated networks and updated communications equipment. Of a global fleet of around 100,000 vessels, approximately 20,000 already have some of the technology infrastructure on board and could be upgraded fairly easily to having industrial internet on board, said ESRG. This is expected to rise by 3,000 vessels per year as most newbuildings incorporate this technology infrastructure. Some owners have adopted industrial internet and CBM. For example, Bernhard Schulte Shipmanagement retrofitted container ship Gabriel Schulte with sensors and a data network. The vessel has integrated main diesel engines, four generators, torque meter, fuel flow meters, ballast and fuel management and lube oil systems, oily water system, GPS and ecdis. The data from all these systems is available on shore for analysis and users can turn the data into actionable information. This enables the master, chief engineer, technical superintendent
and owner to have information on the health and performance of the ship, including fuel consumption, power generation, equipment condition and environmental compliance. Bernhard Schulte chief engineer Guenter Sell said the technology improves ship performance and reduces operating costs. “Not only am I able to assess the equipment performance over time with qualified data, I am also able to have more constructive discussions with the land-based technical superintendents. For example, after creating the visibility I was able to work through a long term sensor problem with the technical superintendent to get it resolved.”
HGO InfraSea Solutions has installed sensors on various systems on its latest windfarm construction vessel Innovation. This vessel was launched with a technology backbone that integrates four asynchronous thruster motors, four azimuth propellers, three motors and bow thrusters, six diesel engines, electrical jack-up system, bridge control system, DP, radar systems and ecdis all linked through the ship’s local area network.

Data can boost ship performance
With good quality onboard data, operators can identify or calculate key performance indicators (KPIs), which they can then use to improve their operational efficiencies and competitiveness. In competitive shipping markets it is important for shipowners to highlight their energy efficient operations and safety records, through KPIs. The next generation of ship deliveries are designed to be as much as 20 per cent more efficient, but without the KPIs this will be difficult to demonstrate. Individual companies can use the information to benchmark vessels in their own fleets, but the information is unlikely to be available from competitors. The newly restructured KPI Association (KPIA) aims to rectify this. The association has been set up to collate and correlate industry-specific data on behalf of the whole maritime sector. It manages the industry-wide KPI project, which was originally created by InterManager. During this year, KPIA is being
restructured to promote safety at sea and best practice. It aims to appoint a global network of regional certified consultants to be the first point of contact for shipping companies and maritime organisations. The consultants will advise shipowners why they should introduce KPIs, said the association’s executive director Helle Gleie. “Having a global network of consultants will enable KPIA

to identify relevant trends and correlations in the data as well as to analyse the feedback from shipowners and maritime organisations. The association expects this will
lead to an improvement in

to advise the shipping industry in the use of performance indicators and statistics, as well as giving us a vital point of contact to receive feedback and inspiration from the maritime sector.” There will be an expert group within KPIA incorporating representatives from key maritime organisations and companies. This group will develop and adapt KPIs to meet emerging industry requirements and expectations. The group will work with industry academics
performance efficiency, maritime safety and environmental standards. Ms Gleie expects that the restructured organisation will attract more shipowners to join the KPI project. “Many companies have struggled when deciding if, when or how to implement shipping KPIs, or have not known how to collect and share this information. Our new structure will enable us to assist with this challenge and spread understanding of how to gather this information to secure meaningful, future focused and commercially beneficial results.”
At the start of 2014, a total of 2,267
vessels worldwide were supplying KPI data to the project’s online database. “We are confident that the new structure will make a difference to its users and the industry as a whole. Only by working together during times of fast change and by sharing knowledge, can the shipping industry develop responsibly and financially with the desired speed,” said Ms Gleie. • The KPI project can be accessed by clients
