Abstract
Machine operators have a large impact on fuel efficiency and productivity. This course teaches participants how to choose the right machines for the job, when to replace them, and how to operate them to reduce an operation’s energy intensity, or fuel per unit of production. The course introduces the concept of tracking fuel use and the factors that drive energy intensity. The course takes 3 hours to complete, including time for questions and answers. Workshop participants can save on fuel costs and boost productivity by up to 10%. This workshop is an essential part of getting the most out of your investment in logging machines.

Abstract
To support the implementation of biomass procurement practices, a formal, rigorous, consistent, science-based biomass quality control (QC) program is needed. This program should be designed to determine customer needs, the sources of product variation, and ways of eliminating or minimizing product variation as soon as it occurs. The program should also include a well-designed QC plan and sampling protocol, statistical process control methodologies and tools, formal QC teams, and regular training. This report describes various statistical QC tools and demonstrates those using examples of biomass moisture content data. These tools can be developed in-house or be purchased, but their integration with existing databases (e.g., LIMS) is recommended. FPInnovations experts can assist in developing customized QC programs for companies and for specific biomass products, and can train QC teams to develop and use the tools presented here.

Abstract
In the pulp and paper and biofuel industries, real-time online characterization of biomass gross calorific value (GCV) is of critical importance to determine its quality and price and for process optimization. Near-infrared (NIR) spectroscopy is a relatively low-cost technology that could potentially be used for such an application. However, the NIR spectra are also influenced by biomass temperature (T°) and moisture content (MC). In this paper, external parameter orthogonalization (EPO) is employed to remove simultaneously the influence of T° and MC on the spectra before predicting GCV. EPO is of particular interest when one desires to transfer information from one modeling experiment to another, such as when developing a calibration model for a new property from the same material, or when it would be more efficient to divide the experimental effort. EPO was found to be an effective method for desensitizing a PLS calibration model to the influence of T° and MC, enabling robust and accurate prediction biomass GCV. Partial least squares (PLS) regression models developed with EPO always provided equal or better performance than models developed without EPO. The paper shows that experimental efforts and costs can be reduced by approximately one half while maintaining prediction accuracy and model robustness.

Abstract
Lack of research and design information for the seismic performance of balloon-type CLT shear walls prevents CLT from being used as an acceptable solution to resist seismic loads in balloon-type mass-timber buildings. To quantify the performance of balloon-type CLT structures subjected to lateral loads and create the research background for future code implementation of balloon-type CLT systems in CSA O86 and NBCC, FPInnovations initiated a project to determine the behaviour of balloon-type CLT construction. A series of tests on balloon-type CLT walls and connections used in these walls were conducted. Analytical models were developed based on engineering principles and basic mechanics to predict the deflection and resistance of the balloon-type CLT shear walls. This report covers the work related to development of the analytical models and the tests on balloon-type CLT walls that the models were verified against.

Abstract
Forestry machines are constantly evolving thanks to technological advancements. As these changes happen, our best practices must change accordingly to ensure optimal safe production and efficiency. For many years, we have used various equipment to bring wood to the road, such as cable yarders, hoe chuckers, and even forwarders on semi-steep ground without the assistance of cable winches. However, there is an increasing need for forwarders to follow harvesters on steeper ground with short pitches. Logging on steeper ground with shorter slopes using winch-assist harvester/forwarder tandems has been taking place in several European countries, Australia, and South America for more than a decade. This manual contains techniques and procedures that will take you through every stage of the forwarding process, including planning, loading, travelling, handling the boom, and unloading.

Les visites réalisées dans le cadre de cette étude ont permis d’établir une structure afin de quantifier le coût d’installation des ouvrages traditionnels (ponceaux) et amovibles (ouvrages dont les appuis sont situés en dehors de la limite supérieure de la berge) en lien avec le RADF. Dans ce contexte, il a été possible de proposer une feuille de calcul permettant d’estimer le coût des ouvrages traditionnels et amovibles. Toutefois, le nombre limité d’observations ne permet pas de tirer de conclusions définitives sur les coûts de ces ouvrages dans plusieurs conditions d’installation.

Abstract
Continuous drying is still in its relatively early stages and mills are currently dealing with process adjustments to obtain desired throughput and quality of the final product. Field measurement carried out in 2015-16 illustrated a number of opportunities for process optimization involving each of the three main stages of current continuous kilns. Simulations of industrial continuous drying at laboratory level performed in 2016-17 were successful and allowed the evaluation of each of the drying stages to be fully characterized (lumber temperatures, drying schedule conditions of dry and wet bulb temperatures). Thus, different drying schedules provided an excellent opportunity to examine the impact of schedule conditions on drying defects, drying rates and kiln residence times. The main objectives of the project for 2017-18 were to simulate continuous drying in laboratory conditions for different products, products mix, species and green sort groups. In addition, a detailed evaluation of potential technologies was carried out to explore the concept of dynamically adjusting speed (push rates), based on drying rates and moisture content. Piecewise regression was used to identify the optimum push rate and suggest design modifications of continuous kilns. This method proved to be efficient in identifying potential reductions in drying time for different sorts of sprue/pine (SP) lumber without compromising the quality of the final product. Simulations also allowed identifying the push rate of 2 feet/h to satisfactorily dry green hem-fir 2-inch lumber. Initial tests showed that mid-sort sub-alpine (moisture content below approximately 70%) could not be mixed with wet sort SP in a continuous kiln operating at push rate of 4.2 feet/hr because only 73% of the sub-alpine sort dried below 21%. Decreases in push rate will reduce the percentage of sub-alpine fir wets but will also increase the amount of over-dried lumber. Changes in kiln configuration may reduce the drying time but increase the percentage of over-dried lumber. The results indicated that additional laboratory tests are required to develop drying schedules and temperature profiles in the main drying zone of continuous kilns, drying times and final moisture content distribution.

Abstract
There was no change to the moisture content of any of the western hemlock log sample sets during the study period between 1 Dec 2014 and 5 mar 2015. It seems that this lack of change is related to stability in environmental humidity experienced by the logs. Whether or not time since cutting influences the ability of Hw logs to change moisture content could not be conclusively determined by the study.

Abstract
Contamination of hog fuel along the supply chain was observed at Skookumchuk. FPInnovations recommends that the number of times hog fuel is moved be minimized, that operators be trained in correct handling procedures, that a penalty/reward system be instituted to habituate proper handling procedures, that cross logs be used beneath log decks, that hog fuel storage surfaces be paved or frozen, and that hog fuel produced in the field be ground directly into chip vans.
