LR Provisional Rules for SPS

Lloyd’s Register, in conjunction with Intelligent Engineering, Ltd, has developed a set of provisional Rules for new construction and ship repair using steel sandwich construction. Entitled Provisional Rules for the Application of Sandwich Panel Construction to Ship Structure, the Rules were approved in early 2006 by a specially convened sub-committee of Lloyd’s Register’s Technical Committee, comprising independent experts drawn from across the industry. Sandwich Plate System (SPS) is a technology created by UK-based Intelligent Engineering Ltd in which two metal plates are bonded to a solid elastomer core. The elastomer provides continuous support to the plates and stops local plate buckling, eliminating the need for stiffeners.

It enables the ship to safely navigate cold weather in temperatures as low as minutes 52 C.

NAPA Releases 2003.1

At press time, NAPA Release 2003.1 was scheduled for launch this spring. Efficiency and user-friendliness are promoted by enhancing the availability of the graphic user interface, and by designing tools for entire processes. For instance, the NAPA Manager process handling tool supplies the user with templates presenting complete calculation chains. The new version includes a number of new features, among them a generic optimization tool. NAPA Geometry now supports the renewed interactive parametric surface definitions. The user can design and choose the parameters desired, as all the main particulars of the ship are always available whenever the software is in use. The NAPA Manager, introduced in 2001 for organizing complex tasks, has forged ahead.

VT Shipbuilding Delivers HMS Daring Foremast

VT Shipbuilding completed its construction work on the Royal Navy’s first-of-class Type 45 destroyer HMS Daring with delivery of the foremast to BAE Systems Naval Ships in Glasgow. The 89-tons steel structure was lifted onto a barge at VT’s Portsmouth Shipbuilding Facility and towed over 600 nautical miles by tug, completing the transit in just over four days. The foremast was then transferred directly to HMS Daring where fitting out will be completed. The major element of the foremast is to house the Sampson multi-function radar suite, which will be linked to the ship’s Principal Anti-Air Missile System (PAAMS). VT has already installed some 12,000 m of cable inside the 19 m high mast, with 800 different cables and 400 pipes included in the structure.

Fatigue and Fracture Analysis of Ship Structures

BMT Fleet Technology Limited, a subsidiary of BMT Group Ltd, announced the next Fatigue and Fracture Analysis workshop for Fall 2011. This three-day workshop will be of interest to Naval Architects, Engineers and Ship Superintendents who are responsible for vessel design, maintenance and operation. Senior students engaged in naval architecture studies would also benefit. The workshop presents tools and techniques for quantitative fatigue and fracture assessment of ship structures considering the materials, structural geometry and loading. Practical application examples are used to reveal the value of this technology in supporting safe and cost-effective material, design and maintenance decisions.

Finite Element Strength Analysis for ATB Load Box

Figure 1: View of Global Finite Element Tug Model.

The loading and response dynamics of an Articulated Tug & Barge (ATB) load box are complex. They typically require advanced finite element analysis methods and procedures to design an efficient support structure to ensure a durable design and to facilitate meeting Class strength requirements. To study the dynamic response of the loads imparted on the tug from the barge, a finite element analysis (FEA) is carried out. Loading conditions that include the static sea pressure, gravity loads, and reaction forces from the ATB Coupler are incorporated into the FEA analysis.

New Fatigue Model Leads to More Durable Ships

The model allows for the development of lighter structures, and as a consequence, more energy-efficient ships.

Heikki Remes, a researcher at the Aalto University in Finland, has developed a model making it possible to determine how fatigue sets in with various welded steel materials. The model allows for the development of lighter structures, and as a consequence, more energy-efficient ships. By utilizing modern manufacturing technology and new materials, it is possible to achieve more efficient structures than the ones that currently exist. In addition, better physical models are needed to ensure structural strength, Remes says.

Jumbo Delivers its Largest Container Crane

Last Month, 2011, Jumbo Shipping delivered a 71-metre-tall and 29-metre-wide container crane to the Port of Sète (France) for its client Eurocrane. Weighing close to 1,200 tonnes and equipped with a transport boom of 104 metres, it was the largest container crane ever transported by Jumbo. With this new crane the Port of Sète significantly increases its container handling capacity. The project presented several technical challenges, which required innovative solutions. The crane’s centre of gravity was located relatively high up and its base protruded by 4 metres off the hull of Jumbo's Fairplayer, which was to ship it. Jumbo’s and Eurocrane’s engineers developed a one-off solution which included adding ballast boxes. • Acting as outriggers for the lifting points.
