Miami launch for Eniram’s OSA
Some 70 large cruise ships have already installed Eniram’s systems says the company, but the system, which is a modular add-on to Eniram’s Dynamic Trimming Assistant, can work on any vessel types.
Assistant (OSA) at Cruise Shipping Miami in March which the company says could save operators up to 3% a year in fuel-related costs. The software analyses real time data

about current sea conditions alongside historical information about a vessel’s performance to determine its optimum speed, ensuring just-in-time arrival in port. Eniram claims that its latest soſtware
tool will radically change the way the shipping industry manages speed, engine use and fuel consumption. The OSA is an onboard decision
support tool that enables a ship’s crew to attain the optimum speed profile for each voyage, allowing vessels to maintain a constant performance and arrive into ports just in time. Te soſtware, which builds on Eniram’s
existing Dynamic Trimming Assistant, combines real-time information about prevailing sea conditions with historical data giving operators the facts they need to be able to sail constantly at the optimum speed profile. Tis reduces the need for a crew to build in ‘buffer’ time and vary engine speed to ensure on-time arrival in port, a practice which is not fuel efficient. Calculations are served up to the
crew via an easy-to-use dashboard and colour-coded ‘traffic light’ system. Tis coordinates all of the information in one place, in a form that can be readily interpreted without the need for any manual input. “OSA shows quick gains in efficiency,”
says Eniram chief technology officer Henrik Dahl.
“For a typical vessel
such as a cruise ship, payback time is significantly less than a year. We see that our OSA together with Dynamic Trimming Assistant will be key elements of any vessel’s energy efficiency plan

“The OSA shows quick gains in efficiency,” says Eniram chief technology officer Henrik Dahl.
innish provider of real time decision support systems Eniram launched its new Optimum Speed
“If you optimise speed, but you don’t optimise the engine you might be gaining two to three percent on the speed side but you might be losing two to three percent on the engine side”
[SEEMP]. Tese tools coupled with Eniram Performance Management reporting and follow-up tools will guide our customers to achieve best performance and reporting of emissions and follow up of EEOI,” he added. Eniram expects OSA to also lead to
a change in behaviour for ships’ crews in the way they use a ship’s engines, Dahl adds. “It is not enough simply to optimise the engine loads for each engine, as the ship might end up consuming more energy. Obtaining the best efficiency on a passenger vessel usually means operating at a constant speed and therefore using the engines at less optimal loads than those for which they are designed.” According to Dahl the company
started developing the OSA product about six months ago. The company has 140 vessels sailing with its data collection platform around the world. The platforms were first introduced with the Dynamic Trimming Assistant product which was rolled out in 2007. Some 700 million signals are collected
daily from the 140 vessels which means that Eniram has a huge data repository of signals which “pretty much describes how vessels operate globally,” Dahl explains. “We analysed 50,000 sea days from the data repository. From that actual vessel data, we could see there is a 2-3% saving on average regardless of whether a voyage optimisation system or a route optimisation system is in use”. He says that there is a big opportunity
for customers to make further savings and so Eniram developed the OSA product. Eniram has recorded a vast amount of dynamic data and has developed the technology in recent years to measure what happens on the vessel. “We have the dynamic data to tell how
much the wind, weather and currents are actually affecting the performance of the vessel”. Te company needed to collect this data to optimise trim, and has now
