DECEMBER 3, 2014 — GE Marine used the opening day of the International Workboat show to announce that Harvey Gulf has chosen GE’s  Tier 4 compliant marine diesel engines for its latest multi-purpose field support vessel ordered from Eastern Shipbuilding.

GE says that Harvey Gulf will be among the first customers to operate the new GE medium-speed diesels that meet EPA Tier 4 emissions standards without SCR after-treatment or urea injection.

“We chose the GE Marine Tier 4 engines for their reliability, low life-cycle cost, capability to meet EPA Tier 4 emissions requirements without urea after treatment, weight and space efficiency as well as ease of maintenance,” said Shane Guidry, Chairman & CEO of Harvey Gulf.

“We are extremely pleased Harvey Gulf selected GE as a partner. We look forward to providing our advanced technology Tier 4 solution which operates more efficiently while meeting the most stringent global environmental regulations to date,” said Afra Gerstenfeld, General Manager of Transportation’s Marine group.

Local support for the Harvey Gulf project will be provided by GE Marine’s Distributor, Cummins MidSouth.

GE Marine’s Tier 4 compliant 250 Series Engine: GE Marine’s family of medium-speed marine diesel engines includes 12- and 16-cylinder V250 models and 6- and 8-cylinder L250 models that range from 1.3 MW to 4.7 MW.

GE Marine offers an innovative non-Selective Catalytic Reduction (SCR) technology for its L250 and V250 series diesel engines that requires no urea-based after-treatment. Eight years in the making, this technology reduces key emissions by more than 70% and enables in-engine compliance with EPA Tier 4 and IMO Tier III emissions standards.

A study to be published in early 2015 commissioned by GE Marine from Jensen Maritime), a leading naval engineering and architectural firm, compares GE Marine’s in-engine Tier 4 solution to a competitor’s solution requiring urea after-treatment on a typical line-haul tug.

A few of the highlights cited in the study include:

  • GE Marine provides a significantly less complex solution with no additional onboard equipment or storage for urea as well as no dockside support infrastructure for urea storage and processing.
  • GE Marine’s engine takes up about only 25% of the engine room space required by the competitive solution.
  • GE Marine’s engine weighs about only 25% of the competitor’s solution.

The study also noted the GE Marine engine’s advantages in fuel savings and operational capability on lower exhaust and ambient temperatures.
