Vaughan Pomeroy, Director of Lloyd's Register's Naval Business, says: "Lloyd's Register has worked on the Type 45 project throughout the design phase and has already approved the design by carrying out an independent assessment against the requirements of the Rules for the classification of naval ships. This contract for survey during construction of the initial production batch of six ships will result in the ships meeting the requirements for classification.
"The adoption of Lloyd's Register's approach to naval ship classification by the prime contractor, BAE Systems, and the U.K. Ministry of Defence demonstrates that we have created a recognized set of standards for front line naval ships. This contract is highly valued by Lloyd's Register, and we look forward to working with BAE Systems and the supply chain to ensure that these ships satisfy the expectations of the Type 45 Integrated Project Team."
The Rules provide a common technical standard for hull structure, machinery, electrical systems and statutory safety requirements in a form that can be applied to any size or type of naval vessel, from aircraft carriers to small patrol boats. With the Type 45 destroyer intended to remain in class for the duration of its service life, control of material state in line with design intent will be clearly visible without the cost penalties that 'unique to navy' standards impose.
The vessels will be built in sections at the BAE Systems yard on Clydeside and at the new Vosper Thornycroft facilities at Portsmouth, with final assembly and launch to take place at the BAE Systems Scotstoun yard.
Lloyd's Register surveyors will work at all yards to ensure construction proceeds in accordance with the approved design. The first of the six vessels, HMS Daring, will be launched in September 2005 and delivered to the Royal Navy in September 2007.

The Type 45 destroyer is the most recent example of the collaboration between Lloyd's Register and the MoD. Lloyd's Register is also preparing to publish its updated Rules for Naval Ships in July 2003. The Rules were first published in 1999 after eight years of development with significant support from the MoD, in particular its Defence Procurement Agency's Sea Technology Group, as well as many other British and overseas defence organisations.

THE MARINE LOG FEATURES CALENDAR FOR 2003
All six to be built under survey in accordance with Lloyd's Register's Rules and Regulations for the Classification of Naval Ships. The classification contract was signed yesterday by Martin Robinson, Head of Procurement, Combat Systems, for prime contractor BAE Systems and Dave Philip, Lloyd's Register's Type 45 Project Manager
HMS Daring will be notable in that it will be the first Royal Navy front line combatant vessel to be built to the requirements of Lloyd's Register's Rules and Regulations for the Classification of Naval Ships. The departure from the use of naval engineering standards reflects the changes which have been made in the Ministry of Defence's procurement practices and its pursuit of SMART acquisition policy. It is also the first major project in the world for which this approach has been applied from the concept stage.
