LNG tank 'fender' takes vessel design beyond B/5

  IMO regulations require a minimum safe distance between LNG tanks and the ship’s shell, which further restricts the naval architect’s design space. RINA article describes the idea of LNG tank placement which provides more design freedom without compromising safety, or even improving safety. Safety considerations IMO’s draft international code of safety for ships using gases or other low-flashpoint fuels (IGF Code) stipulates a minimum safe distance between a storage fuel tank and the ship’s shell of 1/5th of the ship’s beam, B. At other levels the distance should never be less than 760mm (IGF 2014). This requirement has been taken from existing IMO regulations for sea going gas tankers (IGC 2014), which has proven satisfactory over the past 50 years. In fact the B/5 requirement has been copied from the early SOLAS regulations on damage stability which is inspired by damage statistics recorded between 1948 and 1966.  It shows that, given a collision, the probability of the damage penetration not exceeding 1/5th of the ship’s beam equals 55%. It also shows that in 45% of the collision cases, this distance is exceeded. Obviously these statistics are outdated; ship structures have changed significantly since the late sixties of the previous ...

RINA develops new rules for offshore platforms

  Italy’s RINA Services has responded to the challenges of life extension and new regulatory regimes by completely updating its Rules for the Classification of Fixed Offshore Platforms. The new rules and guidelines will be published in May 2015 and will cover classification, certification and verification of fixed offshore oil and gas platforms. Andrea Bombardi, Head of the Energy Department, RINA Services, says, “The rules and guidance provide a comprehensive guide to classification, certification and verification. They are a cradle-to-grave framework for the structural and process safety of the entire platform. They build on RINA’s experience with offshore platforms in the Mediterranean, Red Sea, Indian and Atlantic oceans and the Caspian Sea. The new rules facilitate life extension, reduce downtime caused by inspection and maintenance and give owners more choices and control over their design, operation and maintenance strategies.” Original design, fabrication, installation, structural assessment, topside process certification, life extension assessment and de-commissioning are all covered. Environmental protection is central to the new rules which have been developed with the aim of significantly reducing the risk of accidents and environmental damage. Platform designers and operators can choose from and mix three approaches: classification, certification and verification. Under each of the ...

Interview with Michael Francioni, RINA

S4S: What was the biggest Safety & Environmental protection improvement over the last 10 years? How did it change the industry? M.F: As a classification society, we had big improvements and important steps in rules and regulatory developments. Certainly, the balance between safety and environment became much more important than before.  We had actually an important step in the approval of the Common Structural Rules which were approved by the IACS last December. Also, we have important works going on in the safety over the container ships and a lot of issues going on in environmental parts with several regulations coming up and lot of work done by the various class societies individually and also IACS for implementation of these regulations.   S4S: Do you realize the growing momentum for investing in eco -ships? What are the relevant services and offerings you may provide? M.F: Eco- ship has been a new venture in ship building and in the order book of new buildings. Surely the market has changed, the market is very different than what used to be just a few years back and there are a lot of things that the class society is doing in this aspect. Honestly, ...
