Ship history

The vessel was originally built for Otto Offshore. 

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 vessels are equipped with the most modern solutions for DPII (dynamic positioning), oil recovery and fire-fighting. The ships are recognised as medium-sized PSVs and have a cargo deck of approximately 850 square metres.

These vessels can carry flexible loads. 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). The vessels are certified by DNV and carry the ?Clean Design? notation.


Favourable combination 
The PX121 vessels boast a performance normally expected from a larger PSV. Being able to do this at a medium-sized PSV cost, with reduced emissions and fuel consumption. The ship owner gets a favourable combination of two market areas.

The vessels are of the X-BOW® hull line design, which is efficient on all draughts. A factor critical for PSVs, as they frequently operate with varying draughts. The X-BOW® has unique and documented qualities in head seas, in which the bow shape eliminates slamming and reduces bow impact, noise and vibration. This leads to better performance and increased operability, increased crew comfort and safety and reduced fuel consumption. Each ship will be equipped with a dynamic positioning system Class II and meets the requirements of Comfort Class.

The contract with Ulstein includes the deliveries of design, engineering and main equipment. An extensive delivery from Ulstein Power & Control includes integrated control systems, bridge (radio, navigation), switchboard, diesel-electric propulsion and frequency converters and communication systems.

The vessels will be prepared for offshore crane and mezzanine deck for ROV.


The sister vessels, ?Guo Hai Min Le? and ?Guo Hai Min Rong?, were launched on the 6th and 8th of January 2016, respectively. The vessels are number 2 and 3 in a series of four, all four vessels are now in the ownership of Sinoocean, and have changed names to the following:
