The Graig Group has launched a unique double-hull handysize bulk carrier
design with an eight-ship order in Vietnam. Graig has contracted four Graig
Carl Bro-designed Diamond 34 bulkers, with four options, to be built at
Vinahsin's Pha Rung shipyard. Delivery dates begin in mid 2007.
The Diamond 34 is a new design
34,000 dwt handysize
geared five hatch double
hull bulk carrier which builds on the success of Graig's Diamond 53 double
hull handymax design. Graig is in the final stages of ordering six more
Diamond 53s to be built in Vietnam, bringing to thirty-five the total number
of these vessels ordered to date.
Hugh Williams, ceo of Graig, says, "This expansion of the Diamond concept
into a new size range makes all the proven success factors of the Diamond
available to handysize operators. We have had excellent feedback from the
five Diamond 53's already delivered, and we have developed this new Diamond
34 based on the same concepts. We are also very happy to extend our
co-operation with Vinashin, which allows them to further develop their yards
and Graig to procure excellent tonnage with early delivery dates."
Feedback from the five Diamond 53 vessels delivered from Chinese yards and
now in service for Norway's Spar Shipping and Turkey's Densan Shipping
indicate that power requirements for service speeds are lower than expected.
At the same time, masters report excellent manoeuvrability, which has led to
savings on tug costs, cargo friendliness helping to cut loading and
discharging time, and major savings of time in cargo hold cleaning.
The development of the Diamond 34 design is focussed on:
* economical operation / maintenance * environmental friendliness
* loading flexibility and robustness
* future regulations for bulk carriers
The double hull concept ensures easy discharging and cargo hold cleaning, as
well as a strong and robust hull structure and good environmental
protection, with all bunker tanks coffered from the ships sides. The
bulkhead framing and side frames are all outside the holds, ensuring clean
surfaces in the holds. Cargo friendliness is ensured with large hatch
openings and no lower hopper side tanks in holds 2, 3 and 4. Although there
is a floodable ballast hold, normal ballast condition doe not require the
hold to be flooded, and all ballast can be sequentially exchanged at sea.
The vessel is fitted with four cranes up to 36 tonne capacity each.
The double side skin ensures safe access for close-up survey of the complete
hull structure, even when the vessel is loaded. Furthermore, green water
protection - by the forecastle and the protected underdeck passage to the
fore decks - improves the safe operation of the vessel. The underdeck
passage way also carries all electrical and pipe services thus giving a
clean easy to maintain deck space. Cargo hold lighting units are also easily
accessible from this area.
