KKR-backed Optic Marine Group (OMS) has awarded a contract to build two new cable vessels.

The company this week announced that it has signed contracts with Ulstein for the design and construction of two SX252 cable-laying vessels.

“This milestone marks the latest major step in OMS Group’s fleet expansion strategy and emphasises our commitment to the environment as well as to meet surging global demand for high-capacity submarine cable systems,” the company said.

OMS first announced it was seeking a contractor for the new vessels back in January 2025.

The two new vessels will join the company’s previously announced contract with Royal IHC for two cable-laying ships. Together, OMS said the four new ships will enhance its operational capabilities and support the rapid growth of data traffic and digital connectivity worldwide.

Ronnie Lim, group CEO of OMS Group, said: “With global connectivity demand accelerating, fleet capacity has become a critical constraint for the industry. These vessels significantly enhance our ability to execute complex submarine cable installations reliably and at scale, positioning OMS Group strongly for the next phase of global digital infrastructure growth.”

Cable ships are few and far between. According to the ISCPC, there are around 60 cable ships in operation, many of which are more than 30 years old. With more than 400 subsea cables running and demand increasing, a limited supply of vessels can delay new projects and slow repairs.

Founded in 1983, Optic Marine Group is based in Selangor, Malaysia. The company provides subsea cable installation and maintenance.

Currently, OMS operates six cable-laying and repair vessels – the most recent, the CS Cable Vigilance, launched in 2023 – as well as two barges and three tug boats.

Datuk Lim Soon Foo, founder and chairman of OMS Group, said: “This latest expansion reflects OMS Group’s clear strategic direction, to invest and build a future-ready fleet that underpins the rapidly expanding global digital economy.”

Ulstein is a Norwegian shipbuilder founded in 1917. The family-owned company was originally set up to modify local fishing boats. Its main shipyard is located in Ulsteinvik.

Designed by Ulstein Design & Solutions AS and scheduled for delivery from Ulstein Verft in 2028, the vessels will be 130 metres long and 22 metres wide, with a capacity of up to 6,500 tonnes of cable.

“At Ulstein, we are proud to partner with OMS Group on these next-generation cable-laying vessels. This confirms Ulstein's position within the design and construction of special-purpose ships. By integrating our proven Ulstein X-Bow design with advanced technologies such as the Ulstein Power Variable Speed Generator (VSG), we deliver vessels that set new standards for operational efficiency and environmental performance in this market. These solutions reduce fuel consumption and emissions,” added Gunvor Ulstein, CEO at Ulstein Group.

In 2024, OMS Group secured $300 million in loans through a syndicated facilities agreement with a financial institution consortium to expand its cable ship fleet. The company also announced plans to invest $300 million in subsea and cable infrastructure in September 2024. KKR invested $400 million into the company in 2023.
