Abstract
Les systèmes de contrôle de pression (TPCS) ou de gonflement central des pneus (CTI) deviennent de plus en plus populaires dans les opérations forestières canadiennnes comme moyen d'accroître la mobilité des camions grumiers et de prolonger la saison de transport. Cependant, il existe très peu d'information quant à leurs coûts de possession et de fonctionnement. FERIC a observé les systèmes TPCS Redline-Eltek et TPCS Eaton durant une période de trois ans. L'étude portait sur 24 camions grumiers de configurations variées, localisés dans six endroits différents de l'ouest du Canada. Le rapport présente les coûts de possession et de fonctionnement des systèms TPCS pour ces 24 camions et décrit comment le taux d'utilisation du camion affecte les coûts de possession du TPCS et du camion.

Abstract
In order to provide bridge designers with better information, International Forest Products Limited (Interfor) asked the Forest Engineering Resarach Institute of Canada (FERIC) to evaluate the bending strength and stiffness of log stringers used for constructing bridges on forest roads in coastal British Columbia. Given the lack of definitive standards for testing this material, FERIC developed a field-based test procedure and designed a test facility for destructive testing of full-size, whole-log stringers obtained from second-growth stands. Sixteen coastal Douglas-fir and twelve western hemlock logs were tested in 2003. This report describes the test procedure and methods of analysis, presents the log bending strength and stiffness results, and makes recommendations regarding future testing.

Abstract
The B.C. coastal forest industry relies heavily on water transport for the movement of logs. Logs are traditionally made into bundle booms or loaded onto barges and are towed by tug boats to sort yards or docks, or to mills for processing. This method of transport has been preferred due to its cost-effectiveness, given the unique and challenging terrain of the coast. However, by transporting logs in water, additional cost is incurred in the mill due to corrosion of equipment from salt water. Further, it is more challenging to find uses for, and to dispose of, salt-laden mill residuals, such as hog fuel. Previous work done by FPInnovations compared different modes of log transport: truck, boom, and small and large barge on a hypothetical trip from Campbell River to Nanaimo. The study found that when both direct and indirect costs are included, transporting logs by small barge and keeping them out of salt water is the most economical means of transport. Operations south of Cape Caution, which is on the east side of Vancouver Island, and the west coast of mainland B.C., could potentially replace log booms with small barges, should it be more economical to do so. The original report compared truck transport to water transport. The current report will solely focus on comparing the costs and operational implications of switching from log booms to small barges.

Abstract
This study tested ultra-high molecular weight polyethylene (UHMWPE) ropes for log load securement. Destructive testing of used rope samples done in a previous project found that the strength of these ropes decreased with use. To address this problem, the diameter of the synthetic rope was increased. In addition, a different type of rope with a UHMWPE inner core covered with a polyester protective jacket was tested. The outer jacket protected the inner core from dirt and abrasion which may help mitigate the loss in strength that occurs with use. Wrappers were put into service and tested for breakage after three and six months of use.

Abstract
Steel cables with sections of chain on each end are commonly used as wrappers or tie-downs (the term wrappers is used throughout this report and refers to both types of applications) to secure log loads, as outlined in National Safety Code Standard 10 – Cargo Securement (Canadian Council of Motor Transport Administrators, 2013). These wrappers are heavy, so it can be difficult for some drivers to throw them over a log load. Some senior drivers develop shoulder injuries that result from throwing wrappers, which may make them unable to continue working in the profession. For others, the inability to throw a load wrapper over a load may act as a barrier to entering this line of work.

Abstract
As part of FPInnovations’ and BC Forest Safety Council’s ongoing evaluation of fatigue management technology, Seeing Machines’ Guardian Gen 2, an eye-tracking–based driver assistance system that monitors driver fatigue and distraction, was evaluated in Interior B.C. log-hauling operations. In addition, driver fatigue scores based on a wristband technology, Readiband, were correlated with the drivers’ reported scores to verify the fatigue level in the participating fleets. The study findings, participants’ feedback, and onboard device performance are summarized in this report.

Abstract
Wide-base single tires are receiving renewed interest in the forest transport sector due to their inability to capture rock, as happens with dual tires, which can improve road user safety. Potential fuel efficiency gains are also attractive and, in support of this, the fuel consumption of a 9-axle tridem drive B-train truck was measured relative to a control truck under the following conditions: baseline, wide-base single tires on truck and trailer, and wide-base single tires on trailer only. The fuel consumption differences were insignificant, but the reductions in tare weight were significant. The tare reduction can be best used to carry more payload and increase revenue. Other potential benefits of wide-base tires are related to improvement of vehicle, operator, and public safety. Recommendations for implementation and economics of fitting wide-base single tires are discussed.
