Compliance with Maritime Regulations

Our marine surveyors are heavily involved in the engineering and builds of our winch & deck machinery. This makes them the ideal candidates to oversee the safety and maintenance of your winches and deck equipment. Our inspectors perform detailed surveys by combining thermal imaging technology, vibration analysis, and physical examinations of the equipment.

When the equipment passes inspection, Sentinel issues a report that states the equipment is safe and in compliance with maritime regulations. This quantitative report is valuable for Coast Guard inspections. In the case that the Sentinel surveyors diagnose an issue, a parts & service estimate will be included with the report. The report will be completed as soon as possible to get your winch repaired and back on the job.

Field Service

No location is too remote for our marine surveyors and engineers. The Sentinel team will travel to your location to meticulously inspect and scrutinize your deck machinery to look for breaks or weaknesses. No need to come into port or dry dock for a winch inspection. For repairs, our team will work around the schedule of your vessel to bring your vessel into port or dry dock. This saves you time and money that your ship can be making out on the water.
