KESTO, the joint venture between KMC Line and ESVAGT, has signed its first long-term offshore wind service agreement in South Korea.

From 2028, and for a minimum period of ten years, KESTO will support Vestas with offshore service logistics at the ShinAn-Ul Offshore Wind Farm, marking the formal start of KESTO’s operational journey.

Under the agreement, two 27 m Crew Transfer Vessels (CTVs) will be deployed. The vessels will be designed in Europe and built at a Korean shipyard, supporting the safe and efficient daily transfer of technicians to Vestas’ V236-15.0 MW wind turbines, while contributing to the development of the local maritime supply chain.

KESTO said it combines KMC Line’s local maritime presence and regulatory expertise with ESVAGT’s offshore wind and safe transfer experience, delivering international operational standards anchored in a solid Korean foundation.

Han Cho, Representative Director of KESTO, said the agreement marks the official beginning of the company’s operational journey. He added that KESTO will focus on operational readiness well ahead of vessel delivery, including structured crew training and preparation, to provide Vestas with a safe, reliable, and long-term offshore service solution.

KESTO also said it looks forward to supporting Vestas and contributing to the continued growth of offshore wind in South Korea.
