Powering Maritime Police Vessel

Volvo Penta IPS powers Massachusetts Environmental Police patrol boat

Posted on August 28, 2014

The Thomas Paine, the 15.24 m aluminum patrol boat that joined the Massachusetts, U.S.A., Environmental Police fleet in July, is the first commercial vessel in North America to be powered by Volvo Penta IPS propulsion.

Built by Metal Craft Marine Inc., the new vessel is equipped with twin 380 kW Volvo Penta D11 marine diesel engines driving IPS650 steerable drive units. Power Products, the Volvo Penta Power Center in New England, was responsible for supplying the propulsion system and overseeing installation.

The Volvo Penta IPS consists of a steerable underwater drive unit with two forward-facing counter-rotating propellers. The drive units pull the boat rather than pushing it through the water, the company said, providing 40% higher cruising range, 20% higher top speed, 30% better fuel economy, 30% reduction in CO2 emissions and 50% reduction in noise levels compared with traditional inboard shaft drives.

The Thomas Paine is the latest addition to the Massachusetts Environmental Police fleet, which patrols coastal and territorial waters; investigates illegal fishing practices and marine theft cases; enforces boat registration and titling requirements; mediates disputes between competing fishing interests such as draggers, gill-netters, lobstermen and recreational anglers; and provides security patrols during major maritime events such as LNG tanker escorts and tall-ship parades, and during elevated MARSEC levels in Boston harbor.
