Dometic Marine recently strengthened its position as a quality supplier of heating, ventilation and air condi- tioning by growing its footprint in the wider commercial marine sector. One such high-pro? le project includes the on-board systems for Harvey Gulf Internationals new- build projects. After securing the contract through Lem- oine in 2011, Dometic worked Harvey Gulf, builder Gulf Coast Shipyard Group (formerly Trinity Offshore) and Louisiana-based Lemoine Marine Refrigeration to develop custom systems for the forthcoming lique? ed natural gas (LNG)-powered Offshore Support Vessels. This allowed Dometic Marine to enhance, adapt and customize its in- novative DuraSea Air-Cooled Condensing Units to ensure the equipment will withstand the extremely harsh marine conditions associated with life on board these unique, en- vironmentally-friendly vessels. The ? rst Dometic Marine-built ship-set, comprised of four 10-ton DuraSea Air-Cooled Condensing Units, two six-ton units and two ? ve-ton units, was delivered to the Gulf Coast Shipyard Group in late July. Built speci? cally to operate ef? ciently for long periods in all extremes of sea and weather, the units arguably combine to form the perfect vehicle to support crew well-being and to ensure the correct environment for sensitive electronics and other systems on board todays increasingly sophisticated and far-ranging OSVs operating in the Gulf of Mexico. HARVEY GULF PROJECT A potential game-changer in the move towards an up- surge in the adoption of LNG-fuelled vessels across the marine and offshore sectors, Harvey Gulf Internationals six clean-burning, LNG-powered Offshore Support Vessels intended for deployment in the Gulf of Mexico will make Harvey Gulf the largest owner/operator of environmen- tally-friendly LNG OSVs in the world. Each STX USA Marine-designed vessel will be able to accommodate up to 42 crew members, with Harvey Gulf giving particular consideration to enhancing the crew comfort and accom- modation on its OSVs. For instance, the vessels have spa- cious quarters, modern kitchens and common areas with premium equipment and Harvey Gulf extend this consid- eration for crew with their attention to the HVAC equip- ment. Dometic Marine dealer and marine air conditioning and refrigeration specialist Lemoine Marine Refrigeration, secured the contract to supply and install the on-board HVAC systems following a bidding stage in 2011. R&D PRODUCES NEW, ROBUST DESIGNDometic Marine has further driven the technological advancement of its products to meet and exceed the re- quirements of a project to supply on-board HVAC systems for Harvey Gulf Internationals LNG-powered Offshore Support Vessels. Dometic Marines stainless steel DuraSea Air-Cooled Condensing Units were further enhanced and developed to incorporate several signi? cant design changes along with the addition of several features after prolonged discussions between the parties. The enhancements were largely initiated due to concerns about the harsh and vary- ing sea, weather and temperature conditions endured by the vessels during sustained operations. These design-led innovations and additional features and enhancements can now be offered to future commercial clients. The ? rst Dometic Marine-built ship-set, comprised of four 10-ton DuraSea Air-Cooled Condensing Units, two six-ton units and two ? ve-ton units, was delivered to the Gulf Coast Shipyard Group in late July. Built with a cabinet of stainless-steel 304 to resist heavy salt spray and UV damage, the DuraSea Condensing Unit is part of Dometics DuraSea air-cooled direct expansion air conditioning equipment range. It is suitable for deck or rooftop mount and employs a unique, vertical fan de- sign which prevents water puddling on the fan blades.
