Our Advantages

Experienced Masters & Officers

All of TSG's superintendents possess the knowledge and skills needed for cargo operations and have extensive experience as Master or Officer aboard large-scaled ocean going tankers and coal carriers as well as experience as Berth Master at tanker terminals. They are committed to conducting safe cargo operations by utilizing their know-how.

Independent Company

One of the advantages of TSG is that we are an independent company, not acting as a ship manager, operator or ship owner. This means that owners and ship managers can request safety superintendent and/or other services with confidence that all matters concerning their ship will remain confidential and not shared with competitors.

Superintendents all over Japan

The office is conveniently located in the heart of Tokyo with superintendents strategically placed in various locations across Japan. TSG can dispatch a Master who lives near a terminal thereby minimizing owner's expenses.

Accumulated Know-How

All occurrences, incidents and information from attendance are reported to the office and forwarded to next safety superintendent for the next port or for the next voyage when the ship returns to Japan. Technical know-how is accumulated at the office and conveyed to each superintendent when necessary prior to attending a ship.
