The 94-metre long vessel is capable of supporting offshore exploration, production and subsea construction activities.
Named Greatship Mamta, Keppel Singmarine said it was built to meet stringent standards of safety and stability.
The shipbuilding arm of Keppel Offshore & Marine added that this is a safety record and merits a bonus of US$10,000.
Looking ahead, the company said it will focus on its core competencies to meet demands in the offshore and marine industry.
It is also currently constructing a fourth vessel for Greatship and expects to deliver it in the third quarter of this year.
