Eastern Shipbuilding to build 194 ft fishing vessel

OHara-press-release-340APRIL 5, 2013 — Eastern Shipbuilding Group, Inc., Panama City, FL, has signed a contract with O'Hara Corporation of Rockland, ME, covering construction and delivery of a 194 ft (59.13 m) freezer stern trawler fishing vessel built to a Skipsteknisk, AS, Aalesund, Norway, ST 115 design with a highly efficient hull shape that reduces hull resistance and increases fuel efficiency. It will be built to DNV class +1A1, Stern Trawler, E0 Notation for hull and DNV ICE 1B.

To be called the Araho, the vessel is scheduled for delivery in mid 2015 and will be the sixth fishing vessel delivered to the O'Hara Corporation in a relationship that goes back to  the 1996 conversion of a catcher processor vessel.

The Araho is to be fully equipped with state of the art systems for bottom and pelagic trawling with single trawl.

The winches will be electrically driven. Provided by Rapp Hydema, they are designed for regeneration of power.

The main processing equipment, in the enclosed factory will include various types of fish heading machines and factory systems, consisting of transport systems, fish grader, storage tanks, weighing graders, weighing system, packing tables, packing machine, automatic horizontal freezer system, block elevators, etc.

The design intention of the process deck layout and the equipment selected for transport and handling is to achieve a system with the largest amount of automation, assisting the employees working in the processing area. This arrangement is designed to achieve very high throughput with minimum fish damage and improve employee efficiency — all in a clean and safe work area.

The vessel will be outfitted with three working cranes for various onboard operations.

One aft deck crane is dedicated to work during fishing operations. It is a 360° deck crane with a telescopic boom with a lifting capacity 6,400 pounds and a maximum working radius of 35 feet.

One midship deck crane (also 360°and with a telescopic boom) is dedicated as an off‐loading crane for continuous operation in port.

One forward deck crane is also dedicated for continuous operation during off‐loading in port. It is a 360° deck crane with knuckle boom operated by its own hydraulic power unit.

The vessel will be powered by one EMD MEL16‐710G7‐Tier 3 diesel engine rated at 4,000 HP at 900 rpm and provided by Valley Power Systems, Inc. of Seattle, WA. The propulsion vertical offset Lufkin reduction gear model VSQ4134HG‐K‐PTO with a 7.20:1 reduction is owner supplied.

While underway, a propulsion gear driven 1,700 kW shaft generator will provide constant voltage and serve as the vessel's primary electrical power source for utilization of the vessels total installed equipment, winches, processing, fish handling systems, pumps and ships services, etc.

Secondary electrical power is provided by two 550 kW Caterpillar C18 Tier 3 generator sets and emergency power is provided by one 95 kW Caterpillar C4.4 Tier 3 emergency generator. All are rated for 60 Hz, at 480 V AC.

The accommodations and interior outfitting are designed for 54 persons, excluding the hospital, and are, completely insulated for the harsh working environment. Marine Interior Systems of Covington, LA, is Eastern Shipbuilding's selected Joiner and Insulation sub‐contractor for the vessel. The two companies have a strong working relationship that has spanned almost a decade.

Eastern Shipbuilding has a long relationship with the O'Hara Corporation that has seen it deliver five previous fishing vessels to the company.
