Singapore-based offshore marine services provider PACC Offshore Services Holdings (POSH) has secured a lump-sum subsea diving and installation contract from Subsea 7, a major offshore engineering and services contractor headquartered in the United Kingdom.

The award was made through Subsea 7's Saudi Arabian subsidiary, Subsea 7 Arabia Co. Offshore execution of the project is scheduled for the third quarter of 2026.

The contract will deploy POSH's multi-purpose offshore construction vessel Posh Deep C, a DP3-class vessel built in 2003 and equipped with an integrated saturation and air diving system. DP3 denotes the highest level of redundancy in the International Maritime Organization's dynamic positioning classification, enabling the vessel to maintain precise station without anchoring even if a single fault occurs—an essential capability for safe subsea construction and diving operations in close proximity to offshore infrastructure. Saturation diving systems allow personnel to work at significant depths for extended periods, supporting complex underwater installation and maintenance tasks. Financial terms and further project specifics were not disclosed.

This latest award follows a separate long-term subsea diving services contract POSH signed earlier in the Arabian Gulf region, under which the dive support vessel Posh Mallard DSV is deployed. Together, the two contracts underscore POSH's continued expansion in Middle Eastern offshore subsea operations, a region where sustained investment in offshore oil and gas infrastructure by national oil companies and international operators continues to drive demand for subsea construction, inspection, repair, and maintenance services.

POSH is a subsidiary of Kuok Group and is listed on the Singapore Exchange. The company operates a diversified fleet of offshore vessels serving the oil and gas, renewables, and subsea construction sectors.

Subsea 7 is a global offshore energy services company with operations spanning SURF (subsea, umbilicals, risers, and flowlines), conventional oil and gas, and offshore renewables. The company maintains regional offices and operational hubs across multiple markets, including the Middle East.
