MAN Engines To Power AHTS Vessels
Dubai-based Grandweld Shipyards has been appointed to build two Anchor Handling Tug Supply (AHTS) vessels for undisclosed offshore operators.
The AHTS newbuildings will each be powered by two 8-cylinder MAN L27/38 main engines delivering a total of 2 x 2720 kW in a standard twin screw propulsion layout for driving two ducted cp propellers. The calculated bollard pull is 90 tons. The engines will be shipped from Denmark in 2012.
The L27/38 medium-speed propulsion engine is designed for heavy-duty applications like offshore supply and service vessels, anchor handlers, tugs and workboats. The L27/38 is characterized by good performance over the entire load range, optimized for high-torque layout and dynamic behavior – good acceleration ability with invisible smoke from idling to full load, low fuel oil consumption and low NOx emissions, MAN Diesel & Turbo said.
The engine also features a ‘pipeless’ and modularized design principle. The front-end box is designed with all auxiliary system components for easy access and service. An integrated closed system circuit for lube oil – including engine driven pump, automatic filter, cooler and thermostatic valves – offers safety and easy and cost-effective handling and shipyard installation, according to the company.
