Closing the distance between question and answer

“Technical decisions in shipping have become too time-sensitive to manage at a distance,” said ClassNK TEC general manager, Daiji Aihara. “Owners need direct access to technical judgement, not a longer chain of communication.”

Three forces drove the development of ClassNK TEC (Tech Expertise Center): Greek shipping now accounts for more than 14% of ClassNK’s registered tonnage, this is simply too large to serve remotely; regulation has tightened, turning technical queries into commercial risk; and compliance is now a condition of finance – banks and charterers want independent proof, not promises.

ClassNK TEC is built to answer those challenges faster and with authority. It brings plan approval and rule interpretation to Piraeus, while feeding operational lessons gleaned in Greece back into ClassNK’s rulemaking and service development in Tokyo.

The shift is also digital. Two-dimensional drawings are giving way to 3D model-based approval, using standardised data formats such as OCX. The aim is fewer errors, less rework, and quicker decisions

“Moving from drawings to data models is a fundamental shift,” Mr Aihara said. “It improves accuracy, but just as importantly, it improves how quickly decisions can be made.”

But the constraint is not data. It is consistency. Disconnected onboard systems, manual inputs and fragmented reporting still blunt digital gains. ClassNK TEC works with operators to close those gaps and connect them to specialist teams in Tokyo.

“Our role is not to assign responsibility, but to clarify the technical reality,” Mr Aihara said. “That alone can change the direction of a discussion.”

The stakes are rising. There is no single fuel solution for shipping’s energy transition. The enduring question is not what works, but when, and at what cost.

ClassNK TEC, said Mr Aihara, brings numbers to that uncertainty. Through fleet cost simulations, owners can test fuel strategies, regulatory exposure, and investment timing before committing capital. Regulation becomes measurable; decisions become defensible.

While speed and responsiveness are core values, Mr Aihara is equally clear that the centre’s advice will always be driven by sound and reasoned judgement. 

He also sees the centre’s role expanding into digital assurance and fuel certification across the Mediterranean. The fundamental purpose will however remain unchanged: “Reduce delay, sharpen answers and improve decision making where it matters.”
