SkyLight – a next generation fleet performance monitoring service for optimizing vessel performance

SkyLight is an innovative, next generation fleet performance monitoring service that supports the optimization of the vessel’s performance, enabling ship operators to effectively manage their business.

Eniram and Wärtsilä are launching SkyLight – a cost-effective, next generation fleet performance monitoring service – that offers a vastly improved and more accurate solution compared to manual performance reporting with Automatic Identification System (AIS). With SkyLight, data about the ship’s movements is collected every five minutes and sent via satellite connection to Eniram’s data center. This data, together with the vessel’s noon reports, is combined and enriched with meteorological data, sea state and currents to model the vessel’s speed and fuel performance. This makes it possible to calculate very accurate fuel-speed curves without onboard integration or costly installations. This forms the basis for all ship and performance optimization.

Optimizing vessel performance with real-time data and advanced analytics services

With SkyLight, ship operators can cost-effectively monitor their fleet and compare the performance of each vessel in great detail. The software keeps records of the ships’ performance, enabling more prompt reporting, planning and cost optimization. “Access to fuel and speed performance data increases visibility and supports the optimization of the vessel’s performance. This way, ship operators can manage their business more effectively,” says Jan Wilhelmsson, Vice President Commercial Shipping at Eniram. “Delivering performance monitoring through portable equipment as a service enables operators with shorter business cycles to get the benefits of advanced data analytics. As satellite connectivity is rapidly improving, this type of service is a natural first step in the utilization of real-time data for fuel performance optimization.”

Making performance management available for all

SkyLight will also make the Charter Party monitoring transparent and near real-time. It will deliver an enhanced normalized fuel curve that can improve the optimization of commercial operations. SkyLight’s cost-effective approach makes energy and performance management available to all operators, owners and charterers, regardless of the size of their fleet. SkyLight is a subscription-based service delivered with a portable two-way transponder that is attached to the rail of the ship by the crew. The customer has instant access to the collected and analyzed performance data via Fleet, Eniram’s cloud-based software interface. Reports are also sent to the customer in a PDF format for easy storage.

“With opportunities created by connectivity and the Internet of Things (IoT), we can provide intelligent sensors, integrated satellite communication and web-based analytics tools for optimizing ship performance at cost levels never seen before. This, combined with the vast amount of data Eniram has collected over several years, brings cost savings to our customers and helps them to make the right business decisions,” Wilhelmsson concludes.

Eniram – a Wärtsilä Company

Established in 2005, Eniram provides the maritime industry with energy management technology to reduce fuel consumption and harmful emissions. Created by experienced seafarers and technologists, Eniram’s solutions range from single onboard applications to comprehensive fleet analysis. They are used by small and large shipping companies on ships ranging from cruise liners, tankers, LNGs, container ships, bulkers and ferries. Eniram is headquartered in Helsinki, Finland and has subsidiaries in the UK, the USA, Germany and Singapore. In July 2016, Eniram was acquired by Wärtsilä Corporation in order to strengthen its digital offering and in-house capabilities, specifically in data analytics, modelling and performance optimization.

Time has come for shipping to open up

Wärtsilä’s new Head of Digital says transparency will determine pace of change in development of technology.

By Adam Corbett, TradeWinds

Finland’s Wartsila took a major step forward in the digitalisation of its business through the acquisition of ship-performance company Eniram earlier this year. It was preceded by the appointment of Mikko Tepponen as digitalisation director at Wartsila Services. Tepponen made his name in digitising the Finnish mining and processing business, and now is ready to help Wartsila Services achieve its ambition of making digital operations “a cornerstone for the future”.

Interview with Eniram by Ship & Bunker

Interview with Eniram: First Major Product Since Wärtsilä Acquisition Ready for Launch

In July, Wärtsilä announced its acquisition of Finnish marine energy management company, Eniram Oy (Eniram). With technology set to play an ever increasing role in bunker savings and overall operational efficiency, Ship & Bunker talked to Eniram Managing Director Henrik Dahl about what we can expect following the acquisition, both in the near term, and what might be possible in the longer term.

The exciting news is that Eniram SkyLight, what Dahl describes as a radically new approach to performance management, is set to launch this month.
