Seattle-based Jensen Maritime Consultants Inc. (Jensen Maritime) Thursday announced that its new tractor tug design features "some of the first Tier IV engines" to meet the higher federal air emissions standards, and includes two exhaust cleaning systems to achieve the requirements.

The vessel also features a novel way to meet ballast water regulations - eliminate the traditional ballast water tanks for a bunker-based solution.

Jensen Maritime says that this is the third tugboat that it has designed to meet the Tier IV emissions-reducing performance requirements set out by the U.S. Environmental Protection Agency (EPA), noting that it will be powered by two 3,385 horsepower Caterpillar 3516 Tier IV engines.

"The development of the Tier IV engines for this tug demonstrates our commitment to innovative, environmentally friendly design while continuing to deliver powerful, high-quality performance," said Johan Sperling, vice president of Jensen Maritime.

With an increasing number of ULCVs expected to call at U.S. West Coast ports in the coming years, the multipurpose tractor tug will have escort capability in order to provide support to 18,000 TEU containerships.

"With new ballast water treatment requirements on the horizon from the EPA and U.S. Coast Guard, the tug was designed without any ballast tanks, thereby eliminating the need for ballast water discharge and the potential transfer of invasive species," explains Jensen Maritime.

In place of ballast tanks, Jensen Maritime says the tug will instead transfer fuel when needed in order to maintain proper trim.

The tug is being construction by J T Marine Inc (J T Marine) of Vancouver, Washington with delivery said to be slated for the second quarter of 2017.

In August, Jensen Maritime unveiled two concept Liquefied Natural Gas (LNG) bunker barges, said to be ideal for customers with LNG needs at ports not located near an LNG terminal, or as an alternative to over-the-road transportation.
