About This Project

Moonpool reducer structure

Fabrication, delivery and installation of a moonpool reducer structure. Moonpool dimensions of the client vessel were to be reduced in order to properly operate project specific equipment, the current dimensions of the moonpool allowed the unit to move too much. A cover frame on top of the existing moonpool was developed by our sister company Saltwater Engineering to reduce this excessive movement. Additional specifications such as working platforms (1000kg/m 2 ), railings, stairs, ladders, sheave blocks and a store function of project equipment were designed, manufactured, coated, delivered, assembled and installed on site.

On site installation was achieved by means of bolted connections assuring placement on sister vessels in
due time.

Challenges and solutions

Main challenge was the timeframe and availability of materials in which this frame needed to be made. Only fourteen (14) days were available from first offer to final delivery of the frame. Complete delivery of the full scope of work (including documentation package) was achieved by our local partners, short lines between the engineering and subsequent production proved again to be of great benefit as this resulted in the shortest lead time possible.
