Shipping News Feature
US – Jensen Maritime Consultants, the Seattle-based naval architecture and marine engineering subsidiary of Crowley Maritime Corp., has been awarded the contract to design ship assist and escort tugboats for Moran Towing Corp., a New Canaan, Connecticut tug-and-barge operator on the US East and Gulf Coasts. The new boats will be the latest in a series of seven Jensen-designed tugboats for Moran over the past decade.

New features on the tugboats include upgrades to meet the latest ABS regulations and US Coast Guard subchapter M regulations, as well as meeting US EPA Tier IV requirements. The upgrades will ensure the vessels meet current and future demands for performance and manoeuvrability, and that piping and electrical systems are consistent with Moran’s larger fleet of tugs and barges. Jensen’s Bryan Nichols, director of business development, said:

“Jensen’s team is pleased to continue our long-standing work for Moran, designing tugs that meet high standards for manoeuvrability while delivering compact power in highly capable vessels. We look forward to contributing to the success of the Moran ship assist and escort fleet.”

The 86 feet long and 36 feet wide tugs will be constructed at the Washburn & Doughty Shipyard of East Boothbay, Maine and will be equipped with two Caterpillar 3512E, EPA Tier IV engines with 2,550 horsepower each, and Rolls Royce Z-drive propulsion units, the tugs each deliver more than 5,000 horsepower offering a bollard pull of 68 short tons.

A deep skeg forward is included in the design for escort work, but the skeg will remain open at the aft end to allow for better manoeuvrability. A skeg is the tapering or projecting section of a vessel's keel which also provides for a more stable platform when underway, minimising rolling due to the seaway.

Moran is a leading provider of marine towing and transportation services, a more than 150-year-old corporation that was founded as a small towing company in New York Harbour and grew to pre-eminence in the industry. The cornerstone of their success has been a long-standing reputation for safe, efficient service, achieved through a combination of first-rate people and outstanding vessels and equipment.

Founded by Bruce Doughty, Bruce Washburn and Carl Pianka, the yard began building fishing boats in 1977. Since then, the yard has continued to prosper by diversifying its capabilities, developing innovative designs and building techniques, and reaching out to new markets. Washburn & Doughty has now delivered of a diverse mix of tugboats, commercial passenger vessels, fishing boats, barges, ferries and research vessels.
