Chinese Wuchang Shipbuilding Industry has launched two platform supply vessels it is building for the Singapore-based shipowner Otto Offshore.
The sister vessels Go Matilda and Go Mundara, were launched on January 6 and 8, 2016, respectively.
The vessels are number two and three in a series of four, the first vessel being Go Michigan. The Ulstein, PX121-design vessels for Otto Offshore are capable of supporting offshore activities which are being carried out further from shore and in deeper waters.
Norwegian ship designer Ulstein said that in addition to tanks for various contents such as oil, water, and drilling fluids, they have four stainless steel tanks for flammable liquids or corrosive chemicals (LFL tanks).
A vessel of the PX121 design has an overall length of 83.4 metres, a beam of 18 metres and a load capacity of approx. 4,000 tonnes. The ships are recognised as medium-sized PSVs and have a cargo deck of approximately 850 square metres.
Ulstein further said that each ship would be equipped with dynamic positioning system Class II and prepared for offshore crane and mezzanine deck for ROV.
Apart from design, the contract with Ulstein includes the deliveries of engineering and main equipment including integrated control systems, bridge (radio, navigation), switchboard, diesel electric propulsion and frequency converters, and communication systems.
