Why Oil & Gas Reporting Is Raising the Bar for OSV Emissions Data
Why would an oil company want to know how much fuel your supply vessel burned last month? For years, few charterers asked. Today, many of the companies that charter OSVs report their own emissions against shared frameworks, with independent checks. The Oil and Gas...
The Conversion Gap: What Offshore Fleets Lose Between Data and Decision
