Performance monitoring of heat exchangers – Not as simple as it seems

Author Jussi Parvianen
Posted on

When a heat exchanger generates little heat loss, it may seem that the device works in every way as intended; the heat received by the cold fluid corresponds very well to the heat delivered by the hot fluid. The efficiency approaches unity and the customer can be informed that the heat exchanger works in the desired manner. A closer look, however, shows that the performance evaluation of heat exchangers is not quite such a simplistic matter.

Life Cycle Costing – predicting life cycle costs as part of maintenance management and investment planning

Author 
Posted on

How does one achieve optimal plant operation in relation to maintenance? Production would like to maximise equipment performance and management would like to minimise maintenance costs. Although operational reliability is important for all, maintenance actions are often postponed, and preventive maintenance and change planning are cut in the name of cost-efficiency. Life Cycle Costing (LCC) is a tool that can be used to predict life cycle costs as part of maintenance management and investment planning.

The ballast water issue cannot be wished away – here’s why

Author Mats Nyfors
Posted on

The same questions and claims regularly come up when talking about ballast water and its treatment. “Ballast water has been transported ever since ships were invented”, or “The invasive species have already been transported so the problem won’t get any worse”, or “There were no problems yesterday, why would there be any today”. Despite being rather common claims, they are not accurate. Here is why.

Modern methods in ship structure analysis

Author Leo Siipola
Posted on

Simulations are used commonly in ship design. Finite element simulations, for example, are used in the dimensioning of ship structures and systems, while computational fluid dynamics (CFD) simulations can be used in hull design to minimise ship drag and thereby reduce fuel consumption. CFD is also applied in propulsion design and propeller dimensioning. In this article, I discuss the use of simulations and finite element analysis in ship design.

Concept and preliminary design of energy efficiency measures – Turning optimisation suggestions into reality

Author Jussi Jääskeläinen
Posted on

Energy efficiency audits often generate good efficiency optimisation recommendations, but these are rarely developed into a form that allows practical implementation. The actual investment is clouded in many uncertainties that require clarification, even if the optimisation potential is known. In many cases the next step in optimisation projects is developing a concept, or in the best case scenario, a preliminary design.

Six reed nests for Saimaa ringed seals on Lake Haukivesi

Author Jukka Mikkonen
Posted on

Common reed collected last winter from Lake Tuusula was used in February 2018 to build six artificial nests on Lake Haukivesi. The nests are a continuation of trials conducted in conjunction with the Saimaa ringed seal LIFE project, which is studying how common reed nests can be used to safeguard Saimaa ringed seal nesting during winters of low snowfall.

Why use fuel when there is electricity? – Combustion engines vs battery power

Author Tobias Eriksson
Posted on

Why use fuel when we have electricity?” is a question one hears from time to time. It is mostly asked humorously, with several variants doing the rounds: “fuel” can be replaced with “coal”, “nuclear” and “gas”, or basically any other form of energy generation. Today, this is as relevant as ever, especially in the euphoria surrounding battery utilisation in different forms of transportation

Digital Twin, I and Opportunities

Author Petri Seppänen
Posted on

About a month ago I bought a new GPS running watch. The watch has many features to track your training and how you sleep. One of the new features compared to my old watch was that the user can pair gear (running shoes, bicycles, etc.) with the watch. The user can monitor and track how many kilometers have been cycled with a specified bike. or how many kilometers the user runs with certain shoes. This feature is quite a useful add-on to other information I get from the watch.
