On February 12th, Nantong Rainbow Offshore & Engineering Equipment Co., Ltd. (Rainbow Offshore), a wholly-owned subsidiary of Jiangsu Rainbow Heavy Industries, successfully held the keel-laying ceremony for two SPP40 platform supply vessels. This event marked a critical stage in the construction of these projects and achieved a positive start for 2025.
The N1053 vessel began construction in October 2024, and the N1054 vessel started in November of the same year.
The Rainbow Offshore project team accelerated the production of these projects, carefully planning and achieving the significant milestone of keel-laying both vessels two months ahead of the original schedule.The SPP40 project is a high-performance, multi-functional offshore vessel, measuring 81.75 meters in total length, 17.40 meters in breadth, 7.8 meters in depth, with a maximum draft of 6.3 meters and a designed speed of up to 13 knots.
It is classified by BV and needs to meet the Clean Ship specification requirements of the BV classification society. In terms of the power system, it adopts an advanced electric propulsion mode, equipped with two tunnel-type bow thrusters at the front and two azimuthing main propellers at the stern.
This design allows it to navigate flexibly even in complex sea conditions. Moreover, it is the first to apply cutting-edge technologies such as lithium iron phosphate batteries and fuel monitoring systems, making it an environmentally friendly PSV that fully meets the demands of the international market.
