Yes, there is.
Several years ago the Federal Government finally decided start regulating Inland Pushboats. Amazingly, for years, there was very little regulation such as found in vessels operating off shore and on the open seas.
These new regulations are forcing Towing Companies and Barge Fleets to upgrade equipment and meet certain specifications pertaining to hull integrity and propulsion and steering equipment.
Also, many customers, such as the large oil and chemical companies, are demanding newer equipment to haul and push their product. It has gone so far that many will not let their products be transported in any Barge or vessel that is more than 25 years old.
That's the reason for the new boat construction "boom" that we have been involved in for several years.
Many Companies are now instituting a 30 month major drydocking schedule for their Inland Pushboats. That's about when everything is worn slap out and a refit needed.
Keep in mind. Inland Pushboats, especially the ones that operate on the Intracoastal Waterway, are some of the most abused equipment in industry. Everyday they are running, they are basically self destructing.
