NOVEMBER 5, 2014 — Zhejiang Shipbuilding, Ningbo, China, recently delivered Sea Swift, completing a series of twelve 88.9 m Ulstein PX 105 design platform supply vessels ordered by ship owner Deep Sea Supply PLC, whose largest shareholder is John Fredriken’s Hemen Holdings.
In addition to supplying the basic design for the vessels, Ulstein delivered a comprehensive package of systems and equipment as well as providing on-site support.
The Zhejiang yard, a part of the Sinopacific Group, delivered all twelve vessels during 2013 and 2014.
The vessels are constructed for operations all over the world and several of them are currently working in the North Sea.
“We are very pleased with the vessels – and so are our clients,” says Deep Sea Supply CEO Finn Amund Norbye, “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.”
“We’ve had the pleasure of cooperating with Sinopacific on several occasions,” said Ulstein Design & Solutions project manager Johannes Røren, project manager. “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 m long and 19 ms 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 sq.m 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 included diesel electric propulsion and engines, and the system deliveries included 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 its own company in Ningbo,China, reducing delivery time.
Following the delivery of Sea Swift, Deep Sea Supply has a fleet of 40 vessels: 15 AHTS vessels and 25 PSVs.
