A new class notation from DNV GL aims to help shipowners prepare newbuilds for scrubber installations. Scrubber Ready ensures that the necessary preparations are in place for a smooth and cost-efficient scrubber retrofit at a later stage, the classification society said.

“There is no doubt that stricter emissions regulations for sulphur oxides are here to stay,” said Knut Ørbeck-Nilssen, CEO at DNV GL – Maritime. “This new Scrubber Ready Class notation gives shipowners the flexibility to minimize their initial investment when ordering a newbuilding, while at the same time having the confidence that their vessels are already on the track to easy compliance with incoming emissions regulations.”

“Ship managers have to factor in many considerations when planning for a potential future scrubber installation, from space and stability requirements, to fire safety, piping, corrosion resistance and the effect on the main engine,” said Hans Jacob Horgen, responsible engineer at DNV GL for exhaust gas cleaning rules. “It is very important to have an overview of the design and an understanding of how the system will interact with the engines and auxiliary Continue reading “New DNV GL Class notation announced: Scrubber Ready”

Moisture damage is the source of a significant number of cargo claims. Claimants allege that this is brought about by the ship’s failure to ventilate correctly, resulting in the development of condensation (known as “sweat”). This sweat can lead to the deterioration of a number of bulk cargoes such as grain, seedcake and steel surfaces. All modern bulk carriers are fitted with some form of ventilation, either natural or mechanical, which can be used to minimise the formation of sweat. The London P&I Club has launched new publication LP Focus to address all issues related to bulk carrier ventilation.

Ventilation can also be used for the removal of taint, fumigate gases, or other gases as directed by the shipper. These forms of ventilation only provide surface ventilation, i.e. lacking the ability to penetrate a bulk stow, and therefore cannot continue to maintain an equilibrium in conditioning a cargo such as grain within a silo.

PrimeShip-HULL (HCSR) has long been the go-to design support system for ship designers worldwide. To date, over 800 licenses have been provided to more than 90 shipyards. In response to the latest amendments to the IACS Common Structural Rules for Bulk Carriers and Oil Tankers (CSR BC & OT), ClassNK has just released its latest version, PrimeShip-HULL (HCSR) Ver. 3.0.0.

Adopted in 2013, the CSR BC & OT were designed to enhance safety and reliability. Although they represent a major step forward for ship safety, they also present a number of new challenges for shipyards and designers due largely to the increase in overall vessel design time. To alleviate the burden of these new rules on ship designers and cut down the required man hours, ClassNK released PrimeShip-HULL(HCSR), a multi-functional vessel design support tool that makes it easy for designers to carry out rule calculations and optimize their designs.

Ship breakers are watching the evolvement of mega ships with much interest – not in admiration, but as a future source of metal recycling.

If we’re to believe the big container lines, who justify ever larger ships as the remedy for their financial woes, why are so many of them still losing money?

In the size race, Maersk Line led the pack with its Triple-E vessels of 18,000 twenty-foot equivalent units (TEUs). But nearly all of its chief rivals, including Mediterranean Shipping Co., CMA CGM, Evergreen Line and China Container Shipping Lines, have been catching up with their own mega-vessels. Japan’s Mitsui O.S.K. Lines (MOL) recently announced an order for six 20,150-TEU ships, and Maersk, among others, is likely to match that.
