For inland operators, Compliance, Safety & Technology make for heavy river traffic as software providers descend on a rapidly approaching, potentially lucrative niche market. Is there a panacea for subchapter M? Pending USCG Subchapter “M” (SubM) regulations will eventually require towing operators to implement safety standards and use safety management systems, or alternatively, allow for an annual Coast Guard inspection regime. The new rules are expected to allow towing vessel organizations to customize their approach to meeting the requirements, while providing oversight using audits, inspections, and reviews of safety data. As many as 5,000 vessels and their operators will eventually feel the impact of the so-called subchapter M rules.
