I recently used Diamonds services for an upgrade on my Credential. After completing the initial inquiry, I was contacted within the hour by a member of their team. The entire process from start to finish was very fast and effective. Diamond took the time to review, and answer any question I had. They calculated my sea time, and provided me with all the documentation I was required to submit. Their attention to detail was crucial for my application, and knew to ask for endorsements I was unaware I qualified for.
After receiving my new Credential, Diamond still took the time to answer questions regarding STCW, and provided information on future changes and qualifications. With constantly changing requirements, I will be using Diamonds services for all my future Credentialing needs.


TOAR assessments

Birk Thomas led the class at Boston Line in Boston Mass. Birk was very helpful in guiding the class through the assessments but also shared his own personal experience as well as personal preferred operating strategy for each corresponding assessment. The windy conditions gave a good learning experience to go along with the evaluations. The Eileen C was also a good vessel to assess on as it’s single screw and ran well, and allowed for good visibility to working gear and crew.
