During the 2000's amidst a boom in dry bulk shipping, Graig developed, in collaboration with Ship Designers Carl Bro Intelligent Systems (Denmark), the Diamond Series of Bulk Carriers which lead a new generation of double-hulled vessels.
Working from the many years of experience that Graig has accumulated, we developed a unique business model to support our newbuilding activities. This model was proven to be highly successful and has over many years, generated significant returns for Graig and its partners.
The key features of the Diamond business model are:
Graig explored the dry bulk sector which had issues with sub standard ships and high tensile steel and developed the Diamond Series. The industry's first double hulled bulk carriers of 53,000 MT, Diamond 53 and then followed with the smaller 34,000 MT, Diamond 34.
Both ships were designed to accommodate the latest trends and developments within the Handymax bulk carrier trade, extensive focus was given towards:
The Diamond 34 & 53 vessels were designed by Carl Bro following extensive consultations with DNV for structural and regulatory issues and Graig from an operational view to secure a balance between theoretical and commercially practical aspects.
The designs were a resounding success and many remain in service today.
Graig were one of the very first Western shipping companies to exploit the potential of Vietnam as an alternative location for shipbuilding. Our experiences in Vietnam are an example of how through detailed risk assessment and mitigation, we were able to create value, opportunities and maximise prudent returns.
Graig's unique approach of a) an Owners design b) at a cost effective price but c) with a mitigation of the risk of substandard building through i) a strong specification, ii) a good shipbuilding contract, and iii) top class supervision with experienced “ China hands “ has been a highly successful blueprint for the business.
"The “Diamond 2” Ultramax design aspires to become the class-leading ship of its type, focusing on operational efficiency and flexibility, low fuel consumption and compliance with all present and future environmental standards. It takes advantage of state-of-the-art hull optimization, ballast water management and easily installed exhaust gas cleaning technology. By DNV GL’s formal hull optimization service ECO Lines the hull lines were extensively refined using leading-edge computational fluid dynamics (CFD) simulation technology, parametric modelling and systematic optimization for well-researched operating profiles. The design avoids using appendages, instead featuring an asymmetric stern, a high-efficiency propeller and a rudder with a vortex-reducing bulb. The vertical bow design improves performance across a wide range of weather conditions. Graig expects the efficiency enhancements to result in a fuel consumption of 14.6 tonnes per day at an optimized speed of twelve knots. DNV GL’s Build2Design service will ensure close adherence to the design specifications in resistance-critical areas during hull construction".
