12 PSVs in 18 months

In late October, Zhejiang Shipbuilding in Ningbo, China, delivered ‘Sea Swift’, the final of twelve platform supply vessels of the large PX105 design to ship owner Deep Sea Supply PLC.

In addition to the basic design, Norway’s ULSTEIN has delivered a comprehensive package of systems and equipment as well as on-site support. The Zhejiang yard, a part of the Sinopacific Group, delivered all the Deep Sea Supply vessels during 2013 and 2014. The twelve vessels are constructed for operations all over the world. Several of them are currently working in the North Sea.

“We are very pleased with the vessels – and so are our clients”, states Finn Amund Norbye, CEO in Deep Sea Supply. “ULSTEIN participated in the vessels’ construction and was also responsible for the electrical installations.
Communication and quality of work have been good. We have taken delivery of twelve large state-of-the-art platform supply vessels in approx. 18 months, which must be considered to be very satisfactory.”

Johannes Røren, project manager in Ulstein Design & Solutions, comments:  “We’ve had the pleasure of cooperating with Sinopacific on several occasions, and Zhejiang has much experience in constructing vessels of our designs. We’ve had a site team at the yard throughout the construction of these vessels, and the 12-vessel-project has been characterized by a steady progress and an open dialogue between the parties.”

The Deep Sea Supply vessels are 88.9 metres long and 19 metres in the beam. The vessels have diesel electric propulsion and can keep up a speed of 15.5 knots. The loading deck area is in excess of 1,000 square metres and the vessels each have a dead weight of 4,700 tonnes. The X-BOW® hull line design eliminates slamming from head sea, increases comfort and safety and reduces fuel consumption. The vessels comply with the DNV requirements of either the Clean or Clean Design standard.

ULSTEIN’s equipment deliveries include diesel electric propulsion and engines, and the system deliveries include power distribution and propulsion, automation, internal communication and entertainment, navigation and radio. The vessels were among the first in which ULSTEIN had the switchboards produced at their own company in Ningbo, reducing delivery time due to shipment.

Following the delivery of ‘Sea Swift’, Deep Sea Supply has a fleet of 40 vessels: 15 AHTS vessels and 25 PSVs.
