class / clean design. This is in tandem with current
industry trends towards
vessels with improved design on stability capabilities as well as inherently safer and more environment-friendly operations.” At the time of the sale, Leong stated:
“We foresee that financing for newbuilds available to our customers will tighten in the next year even as oil majors continue to invest in projects, which will create ample opportunities for our built-to-stock vessels to fill the demand.” Expanding on this, Leong says: “We see demand more for AHTS vessels and
PSVs. As offshore service providers replace older vessels with new and higher specification vessels, the demand for small size AHTS vessels remains strong. New businesses relating to topside maintenance, hook up and commissioning and exploitation of reserves from marginal fields have also created new opportunities for the group. “As for our built-to-stock vessels, we
carry out rigorous market research into in-demand vessels [including continued dialogue with customers] before commencing newbuilds. By building our
vessel in advance of order, we are able to respond quickly to any growth in demand for OSVs and to capitalise on rising OSV prices. To elaborate, building in a series is efficient in achieving economies of scale. With this model, we are able to command a higher profit margin because the time period between securing the contract and delivery is expedited for Nam Cheong’s customers.” Tis latest AWB is scheduled for delivery
in the second quarter of 2012 and is being built in one of Nam Cheong’s subcontracted yards in China. OMT

berths, a hospital, conference room, recreation room and five offices. With a range of 5000nm, or around 40
days, the vessel has a maximum speed of 12knots; propulsion is delivered by two Caterpillar 3512B main engines producing 1500kW each at 1600rpm, driving twin fixed-pitch propellers. With both main engines and one generator running, Shin Yang notes that fuel consumption runs at around 20tonnes/day. Dayang Topaz is designed to lend
itself to a number of roles in support of offshore construction and maintenance; the workboat is fitted with a four-point mooring system with capacity of up to 50tonnes, two anti-rolling tanks and a 45tonne SWL offshore pedestal crane supplied by Favelle Favco. The vessel also has a clear deck space of around 700m2 a deck cargo of 800tonnes. OMT
