TMC Compressors, a renowned designer based in Norway, has recently secured a significant order to provide a marine compressed air system for two cutting-edge subsea rock installation vessels being developed for the esteemed Netherlands-based marine contractor, Van Oord.

Yantai CIMC Raffles Offshore has partnered with TMC Compressors to deliver a comprehensive marine compressed air system for each vessel. These systems will include robust instrument air compressors and efficient air dryers designed to operate effectively in harsh maritime environments. The contract’s financial details remain undisclosed, but the implications for both companies are significant, enhancing their capabilities in the competitive marine sector.
Hans-Petter Tanum, TMC’s Director of Sales and Business Development, expressed enthusiasm about the project, remarking, “It is always fun and interesting to equip innovative and unique vessels such as these two. They can play an important role in facilitating the energy transition through enabling, amongst other things, offshore wind projects.”
The new vessels are engineered for success, boasting an impressive loading capacity of 35,000 tonnes, which equips them to handle substantial rock sizes. Enhanced with a DP-2 dynamic positioning system, these vessels ensure precise maneuverability even in challenging oceanic conditions, such as turbulent waves and strong currents. These features are especially vital for long-distance project undertakings, where efficiency is paramount.
By minimizing round trips, the advanced design of these vessels will contribute to reduced emissions and lower costs per installed rock volume. Van Oord’s operational prowess is backed by a fleet of 61 vessels, including three dedicated subsea rock installation units, solidifying their position as a leader in marine contracting.
The sustainable design of the vessels marks a step forward in eco-friendly maritime engineering. Features such as multi-fuel engines that can utilize biofuels and methanol, combined with a DC grid and substantial battery storage, underscore a commitment to energy efficiency. Additionally, an optimally designed hull and advanced rock-handling systems are integral to stabilizing and protecting offshore energy resources. Subsea rock installation is increasingly recognized as essential for the protection and stabilization of these valuable assets.
“Our marine compressed air systems are highly reliable and designed so that the vessel crew can maintain the compressors themselves, even while at sea,” Tanum highlighted. This design consideration makes the system ideal for vessels intended for long-distance operations, ensuring seamless functionality regardless of operational challenges.
This contract is particularly noteworthy, as it follows TMC’s recent partnership with COSCO Shipping Heavy Industry to deliver a marine compressed air system for SBM Offshore’s FSO Chalchi, which is set to be deployed at Woodside’s Trion deepwater oil field off the coast of Mexico. Such consistent engagement with major industry players indicates TMC’s growing influence in the offshore sector.
