Create a World with
No Serious Marine Accidents

Our mission is to “create a world with no serious marine accidents.” No one on-board should encounter a hazardous accident. This is prioritized in the regular operations of our captains, crew members, and land staff. Their daily efforts prevent not only serious accidents but also various other accidents and troubles. We are committed to providing value through safe operation for everyone involved in vessel operation.

Based on our philosophy of “creating a world with no serious marine accidents,” we have established the following Sustainability Policy to contribute to the realization of a sustainable society through the management of offshore vessels and SEP vessels.

Pioneering the future of Japan’s seas with marine expertise and the power of people.

There are two major pillars that we have continued to support.

One is our “crew.”

Because our founder was himself a seafarer, Kyoei Marine has long placed special importance on crew members. In Japan, surrounded on all sides by the sea, crew members who connect islands and support logistics are extremely important. However, the environment surrounding crew has always been buffeted by difficult times, including a slump in ocean-going shipping caused by appreciation of the yen, the trend of rationalization of marine operations, and, in recent years, an aging population and a serious shortage of crew. Even amid such headwinds, we regard it as our mission to value and develop crew above all else and pass this legacy on to the next generation.

The other pillar is “ocean development, surveys, and operations.”

At the time of our establishment, our primary business was the transport of structures to the Persian Gulf area using large tug boats and delivery voyages for ships sold overseas. Later, our work expanded to marine surveys, salvage, and the towing of large barges in waters around Japan, where we continued to stand alongside our seafarers on the front lines of operations. Today, we are also engaged in ship management of subsea drilling vessels and installation vessels for offshore wind power facilities, e.g., SEP vessels. Many of the projects we have undertaken have broken new ground, including initiatives that were the first of their kind in Japan or in the world. We are convinced that this knowledge and experience will turn into an indispensable capability for ocean development and renewable energy projects around Japan, which are expected to accelerate in the years ahead.

“Create a World without Serious Marine Accidents”

Guided by this mission, we will continue to support safe and smooth project execution in the fields where our two pillars meet: marine development, surveys, and offshore operations. Together with highly skilled seafarers, and with advanced technology sustained by the strength of people, we will deliver lasting value to our stakeholders and contribute toward creating a better society.
