Ancillary equipment Cramm on deck
Cramm Yachting Systems has announced that it has added two deck crane concepts to its range of hydrau- lic products. One of the latest features of the cranes is a rotation system that reduces power loss due to friction. To achieve this, Cramm has developed quiet power packs for the cranes. Te cranes are made mainly from stainless steel and produced in accord- ance with Lloyds requirements. “Our aim was to develop an even better crane for a
decent price,” says Cramm director Rob Knoop. “And the enthusiastic reactions prove that we succeeded as dozens of orders have been received in no time.” Te urge for improvement is a constant in Cramm’s product development: All products have been or are currently being restyled.

Engines Type approval for
The V28/33D engine.
more efficient MAN MAN Diesel & Turbos has launched its first upgraded, twenty-cylinder 28/33D prototype engine, which recently passed a series of tests on the test bed at the company’s St. Nazaire, France works, and was awarded type approval by Det Norske Veritas (DNV) classification society.
Te approval has been conducted in compliance
with DNV rules for the classification of ships as well as high-speed light craſt and naval surface-craſt. Te type approval covers a rating of 9100kW at 1000rpm for 100% MCR and an additional 10% overload capacity for one hour every six hours of 10,000kW at 1032rpm. Te four-stroke, medium speed engine is accordingly the most powerful and fuel-efficient diesel engine in its class worldwide. The V28/33D engine range has 12-, 16- and
20-cylinder configurations, a state-of-the-art design featuring a high power density, and maintains full compliance with IMO-II and EPA Tier-II legisla- tion. Te 280mm bore and 330mm stroke engine has a
minimal number of components and is tailored for three main segments: multiple propulsion applica- tions including all types of fast ferry, naval ships, super-yachts; an STC (sequential turbocharging) edition; and as gensets for offshore applications. Te latest engine is characterised by its balanced
ratio between power and weight, high performance, shock resistance, quiet running and high reliability for maximised availability. With its ease of installa- tion and maintenance, it is a textbook example of a diesel engine featuring low operation and life-cycle costs. Additional design features include the new,
in-house-developed safety and control system – SaCoSone – and the high-efficiency TCA33 turbocharger, which has been especially tuned for the V28/33D engine. Due to a higher pressure rate, the turbocharger can reach values of up to 500kW per cylinder. Type approval from the remaining classifica-
tion societies is planned for later this year and the first upgraded 20V28/33D engines on order are scheduled for delivery in autumn 2010.
