HEC presents Committee report on USCG Polar Icebreakers

USCGC Healy Breaks Ice

USCGC Healy Breaks Ice

On Nov 17th, HEC's Eugene van Rynbach presented the findings of the report "Acquisition and Operation of Polar Icebreakers: Fulfilling the Nation’s Needs" to the American Society of Naval Engineers Arctic Day.

The report was produced by the Committee on Polar Icebreaker Cost Assessment of which Eugene is a member. The full report can be read here

NSMV Video Visualisation

19-Sept-15 Side on Aft Global.png

(Annapolis, MD) To help visualise the purpose and design of the National Security Multi-Mission Vessel (NSMV), MARAD commissioned a video showcasing the capabilities of the vessel, and putting into context the urgent need for both cadet training and disaster relief.

A highlights version of the video was produced that focused on the design aspects of the vessel:

DRYDOCK MEDITERRANEO REFLOATED

(Livorno, IT) Herbert Engineering served as a consultant to the salvage refloating operation of the drydock Meditteraneo and the research vessel Urania lying inside. A full article describing the operation can be found here. During the lifting operation a year earlier the vessel listed to the portside and fell from the keel blocks. In the subsequent response a leak caused the pump rooms to flood which put all drydock pumping and control systems out of service.

An Italian naval architect, Alessio Gnecco, of Stige Maritime was hired by the dock manager to prepare the refloating operation, with the Urania to be kept stable on the dock floor in the position she originally fell in. To assist in this task he obtained the cooperation of Herbert Engineering, to develop a refloating sequence and the design of the stabilizing devices.

On September 15, 2016 the refloating operation was kicked off with HEE managing director Luca Letizia attending to monitor stability, trim, list and stresses with HECSalv and to suggest corrective actions should they be found advisable. The refloating operation was a complete success, with the dock safely floating about 12 hours after pumps were first started. The photo shows the assembled team for the refloating operation, including HEC’s Luca Letizia. A video showing the full operation can be found here.

INNOVATIVE WORK FOR LNG FUELED VESSELS

(Alameda, CA)  HEC has carried out innovative work across the broad range of issues involved with adopting the use of LNG fuel in ships.  Concept and bidding designs with specifications have been prepared for several LNG fueled vessel designs.  We assisted ABS with the preparation of their Technical Advisory on LNG Bunkering.  HEC has provide plan approval and technical assistance to owners building LNG ready vessels.  HEC has analyzed the design and cost issues related to fuel selection in the new ECA era including fuel choices MGO, HFO with scrubbers and LNG fuel.  Our white paper presenting the results of this analysis is available here. As the cost of fuel has been changing the lowest cost fuel choice has been changing, pointing to the fact that careful engineering and cost analysis should be carried out before any owner makes a fuel choice commitment as the cost differences can be significant and vary by vessel type and service. HEC has made several presentations to technical and shipping conferences on the impacts of LNG fuel on ship design. The impacts may be more than some owners expect.
