The name on the side of the new fishing vessel delivered by Chantier Naval Forillon isn’t an easy one, but this reflects the Listuguj Mi’gmaq Government’s optimism for commercial fisheries

Ugjit Mijua’ji’jg throwing a clean wake on sea trials

In the Mi’gmaw language, Ugjit Mijua’ji’jg means “For Our Children” and the new vessel is the latest to be delivered to the Listuguj Mi’gmaq Government, an indigenous Canadian community on Quebec’s Gaspé Peninsula.

Designed by Navanex, the 19.81-metre LOA by 7.31-metre beam vessel has a layout that allows it to be rigged for fishing with traps snow crab for part of the year, with a clear aft deck capable of stacking 150 collapsible crab pots. To switch to trawling for shrimp or other demersal species, a gantry with twin net drums can be mounted over the stern, and a platform forward is prepared for a pair of trawl winches to be mounted.

Ugjit Mijua’ji’jg is built in steel and has a raised fo’c’sle with an aluminium wheelhouse. Accommodation for a crew of up to seven is forward in the raised fo’c’sle with the galley and mess in the aft part of that space.

Proven stabilisation

A newly designed bulbous bow, in addition to improving fuel efficiency, helps reduce pitching when working gear into a swell. A pair of stabilisers, follow a design first installed by Chantier Naval Forillon on the trawler Fundy Leader in 2006. A number of these systems have proven effective on other vessels.

The stabiliser is a steel plate, hinged at the bottom on the bilge chine. It can be hydraulically raised flat against the hull or lowered to a horizontal position. According to Chantier Naval Forillon’s technical director Jean-Nil Morissette, this system is effective in dampening motion both when steaming or when working gear.

Propulsion power is provided by an IMO-compliant tier III, Cummins QSK19 producing 750hp at 1,800rpm, coupled to a Twin Disc MGX-5222 gear with 5.04:1 reduction. This turns a four-blade Rice Kaplan Skewed propeller with a 57-inch diameter and a 67-inch pitch. The prop’s thrust is enhanced with a Rice Speed nozzle. This system will give the vessel a cruising speed of nine knots and a bollard pull of 8.2 tonnes.

Increased efficiencies

To meet the IMO tier III emissions, the QSK19 main engine is fitted with an SCR after treatment including DEF (diesel exhaust fluid) injection unit. The system utilises pressurised air to atomize the DEF for better mixing and a complete chemical reaction. This system allows for reduced consumption of DEF.

Multiple housing and configurations are available for these SCR aftertreatment systems. Cummins technicians were able to take advantage of the significant space between the engine room deckhead and the top of the QSK19 main engine. The arrangement allows ample access to the main engine while facilitating ready access for technicians to the service panel.

The engine and aftertreatment system are integrated, controlled and monitored through an electronic interface which displays system out NOx and NOx conversion efficiency on a monitor in the wheelhouse. On trials, the wheelhouse monitor reported NOx reduction of 91.2%.

The comprehensive set of deck equipment includes a Heila HLM 3-2S deck crane. For crabbing there is a crab hauler, crab table, crab boom and crab block. For trawling, in addition to the two trawl winches and net drums, there is a bag winch. The anchor winch is mounted so that the anchor will lower to the starboard side of the bulbous bow.

Auxiliary power includes a Cummins QSB7-DM genset producing 65 kW and an additional QSM11-DM engine producing 355hp at 1,800rpm. This engine drives the vessel’s hydraulic pumps and a back-up 65kW genset.
