Naval Architecture and Marine Engineering

Bristol Harbor Group, Inc. (BHGI) offers design services from the conceptual design through the detail design and shipyard support. Some of BHGI’s design services include but are not limited to hull design, structural design and analysis, stability analysis, and weight estimating. BHGI’s marine engineering practice focuses on the design of new vessels, repowering’s, and mechanical and electrical upgrades. BHGI’s marine engineers have many years of hands on experience, both aboard vessels and in shipyards. This practical experience allows our marine engineers to better understand both operational and technical issues. 

Finite Element Analyses (FEA)

Bristol Harbor Group, Inc.'s (BHGI) mechanical engineers are well versed in finite element analysis (FEA). We utilize NEi and Autodesk NASTRAN, and FEMAP to determine stress and deflection. Our engineers conduct analyses on a variety of projects including but not limited to: simple and complex beam element models, local and global shell models for vessels and foundations, coupled Computational Fluid Dynamics (CFD) and FEA in a variety of sea states to determine vessel hog and sag along a wave train, thermal analysis for cryogenically controlled cargo, and much more. 

Computational Fluid Dynamics Analyses

Bristol Harbor Group, Inc. (BHGI) performs computational fluid dynamics analyses (CFD) analyses using Orca Marine's CFD program to conduct resistance studies on various conditions to predict the performance of the vessel. BHGI uses CFD analysis to estimate ship hull performance in calm waters. This is especially useful when looking to optimize the vessel's hull form to improve fuel economy. We have used our CFD capabilities to conduct comparative studies of barges, tugs, towboats, and ATB units. From these studies, hull form was able to be optimized to provide vessels with improved flow and resistance characteristics. CFD results include running waterline, resistance, wave train, pressure plots, and a variety of other analyses. BHGI uses these results to determine the best hull for the client's needs. 

Consulting Services

Bristol Harbor Group, Inc. (BHGI) provides technical support and consulting services to vessel owners, charterers, and operators. These services can be in support of new construction projects, modifications, regularly scheduled dry docks or more comprehensive maintenance periods.  This can include anything from shipyard selection to construction oversight. BHGI also provides life-cycle management and fleet reviews, among many other consulting services. 

LNG Bunker Barge

North America’s First LNG Bunker Barge was delivered in the 3rd quarter of this year to TOTE Maritime. The CLEAN JACKSONVILLE is a 232’, 2,200m3 liquified natural gas (LNG) bunker barge that features one tank equipped with MARK III Flex cargo containment technology, from the French engineering and technology company GTT (Gaztransport & Technigaz). Bristol Harbor Group, Inc. (BHGI) was responsible for the design and engineering of the barge. The barge was built at Conrad Orange Shipyard in Orange, Texas. BHGI served as the regulatory lead and liaison between the regulatory bodies.

U.S. Army Corps of Engineers IDIQ

Birstol Harbor Group, Inc. (BHGI) has been tasked with a number of projects through our second five-year IDIQ contract with the U.S. Army Corps of Engineers (USACE), Philadelphia District. Some of the projects BHGI has recently worked on include: Completion of the design of a USACE wicket lifting vessel for operation at Olmstead Lock & Dam on the Ohio River. BHGI will also continue to provide design and engineering support to the USACE for the NASA barge PEGASUS. BHGI has also been tasked to perform design work and technical assistance to modify and develop upon an existing Marine Design Center debris collection vessel, REYNOLDS, a multipurpose vessel design for the National Park Service, Statue of Liberty National Monument and Ellis Island. BHGI was recently tasked to develop a contract level design for the DRIFTMASTER II. 

Delivery of 85k BBL Double Hull Oil Barges

In 2015, Bristol Harbor Group, Inc. (BHGI) was contracted by Conrad Industries, Inc. to develop the design of a 403’ x 74’ x 32’, 85,000 BBL double hull AT/B oil tank barge for Vane Brothers Company. The design is based on a previous proven hull design that BHGI had completed for Conrad. The last hull of three sister hulls was recently delivered. The construction of the barge took place at Conrad Deepwater South in Amelia, Louisiana and it is certificated by the American Bureau of Shipping (ABS) and the United States Coast Guard for unlimited oceans-unmanned service. The barges are equipped with a complete loading and discharging system in 10 tank compartments that include a cargo 10 MMBTU thermal heating system.

New York Power Authority Replacement Tugs

Bristol Harbor Group, Inc. (BHGI) was contracted by the New York Power Authority (NYPA) to design and perform construction supervision support services for two (2) new tug vessels. The tugs will be used for the deployment, retrieval and maintenance of the Lake Erie ice boom. The construction for the JONCAIRE II has been completed. BHGI developed and revised the second vessel specifications and bid drawing package in close collaboration with the operators, including significant detailed system design for the second vessel to provide improved ergonomics for the crew. NYPA recently awarded a contract to a shipyard for the construction of the B-2 BREAKER tug. BHGI is again performing construction oversight services on behalf of NYPA.

Sayville Ferry

Bristol Harbor Group, Inc. (BHGI) was recently contracted by Sayville Ferry Service, Inc. located in Sayville, NY to provide the design of an aluminum monohull high speed ferry for 400 passengers and cargo providing service from Sayville to Fire Island. The new design will be based on an existing parent vessel. The vessel will be designed to comply with 46 CFR Subchapter K. The project includes both preliminary and detail design packages for all aspects of naval architecture and marine engineering. There is particular emphasis on modernization of the propulsion plant, improvements for passenger embarkation/debarkation and cargo handling, hydrodynamic enhancements, and vibration reduction.
