Key Features

Experienced Marine Winch Inspectors

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.

Compliance With Maritime Regulations

OEM administered surveys and inspections enhance the safety, reliability, and ensure regulatory compliance of your winch system. With the Markey Sentinel Survey a customer can use it to ensure their essential towing systems are in compliance with Coast Guard Subchapter M regulations by The United States Coast Guard regarding safety, proper equipment maintenance, and record keeping. Our team will make sure your winch or deck machinery is up to par for the Coast Guard and safe for your crew to operate.

On-Site & Remote Access Services

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.

Remote Access

Remote Access service allows our systems engineers to troubleshoot your control system from anywhere in the world. We can remote access your control system the same day you encounter a problem, saving you valuable time and money and preventing a costly trip back to port.

OEM Replacement Parts

Quick access to spare parts is critical to any successful operation. We stock critical wear items and can quickly produce service parts regardless of the age of your winch. Markey Machinery keeps detailed engineering records for virtually every winch or deck equipment item the company has ever built. Over the years, many electrical, hydraulic, and pneumatic product lines and components may become discontinued or obsolete. We actively identify reliable alternative components and suppliers to extend the life and functionality of your deck equipment.
