PARAT Halvorsen three-in-one Combined Steam Boiler adds Shore Power to production trawler optimisation options

PARAT Halvorsen AS, Norway’s leading supplier of combined steam boilers for fishing, commercial marine and offshore applications, has launched a three-fuel boiler offering unique flexibility to vessel owners and operators in the fish production sector.

The company’s MCS Combined Exhaust Gas / Fuel-Fired / Electrical Boiler is a compact and highly efficient unit enabling trawler operators to switch between three different fuel sources and significantly reduce emissions. The additional fuel flexibility will cut emissions, provide additional electrical back-up during vessel operation, and raise vessel productivity.

Suitable both for newbuildings and retrofits, the boiler can produce steam from shore power during port calls, thereby cutting emissions; it can be used to optimise power generator load during transit; and the unit can also burn fish oil produced at sea, to extend fishing trips and prevent unnecessary return voyages to port.

The boiler, with smoke tubes, is available in vertical or horizontal configurations and has been approved by most major classification societies. Its electrical connection is available at 400V, 440V or 690V depending on the power distribution system on a new or existing vessel.

Johnny Svindland, Head of Marketing at PARAT Halvorsen, explained: “The MCS boiler is designed mainly for fish production trawlers. Now, with electrical connection, vessels will be capable of producing steam from shore power to reduce emissions in harbour. The burner is also capable of burning fish oil produced at sea to prevent unnecessary return voyages to port. The three-way fuel flexibility is a really significant benefit both for newbuilds and existing ships.”

In another key development, owners of existing vessels with combined PARAT boiler installations as well as boiler systems from other manufacturers can also upgrade steam production arrangements with the PARAT ECS Electrical Circulation Steam boiler, optimised for steam boiler retrofits. This allows users of existing steam boilers to add electrical system benefits, both via Shore Power-based steam production and back-up during transit. The compact solution enhances flexibility and reduces through-life maintenance costs in the process.

The boiler, which has an automatic setting for unmanned engine room operation, can be used both as a source of extra power during routine voyages and as a means of reducing fuel consumption. Similarly, its electrical connection can be delivered at 400V, 440V or 690V. The unit’s programmable logic controller (PLC) can be connected to a trawler’s main control system by standard ethernet / profibus / modbus links.

PARAT’s Svindland commented: “The ECS boiler can be used to upgrade any existing fishing vessel to provide an electrical connection as a back-up, enabling generator loads to be optimised and for shore power to be used when available. Installations, which can be vertical or horizontal depending on layout and space constraints, can be undertaken on existing trawlers in port or at sea, with the retrofit upgrade and boiler optimisation managed by PARAT as a turnkey project.”

The ECS boiler is available as a standard modular unit in capacities up to 500kW, equivalent to 750kg steam per hour. More powerful units are also available on request.
